Fishing In the Woods: Looking for Radio Signals



This was the first Winter Field Day that justified a reason to purchase an ice fishing tent.

The tent manufacturer claims you can set this up in under a few minutes and pack it up even quicker.  Lets see what the breakdown looks like.



 
Inside the Tent:  Gear needed

We all like lists right?  Here is what was in use in the photo below.

Excluding the table, chair and propane heater, this was a minimal operation which proved pretty comfortable even in the low temperatures during Winter Field Day.

The goal was to operate 10m or 15m  PSK31, JS8CALL or SSTV but most of the time it seemed that FT8 was more popular, so that would not count for Winter Field Day. Too bad!!   The 15m band was wide open which was really nice.  A few contacts were made on 40m SSB, hence the need for the headset.

Antenna Questions

A 40m Off Center Fed home made dipole was used with good success.  This design allows for 40m, 15m and 10m operation without really needing the tuner..  One leg of the dipole is 44 feet and the other is 22ft.  At the center point is a 4:1 DIY balun.  The antenna center was mounting with velcro ties on the 20ft orange Jackite fiberglass mast.   

The mast was secured to the ground with a ground stake and length of PVC pipe which the mast simply slides over.  The longer end of the dipole was attached to a nearby tree with a length of paracord.  The shorter end was attached to an artificial tree known as a tripod.

Even with heavy winds, the antenna system as expected maintained upright for the 24 hour event in the frigid cold!

This antenna system works great and easily stows in a bag designed for audio equipment.  Many other accessories for additional HF and VHF antenna also fit in this bag along with a few 25 and 50 foot RG-8X feedlines. 

I would estimate that my entire antenna kit which includes the storage bag, surplus tripod (RIP KE2EJ), feedlines, support stake, full wave 2m loop, Arrow II antenna, 40m OCF, 10m-17m-20m-30m linked dipole,  End Fed 40m/80 and a few other odds and ends cost less than $200.  This is a lot of antenna gear for different applications mostly meant for POTA operations and not SOTA activity which is much smaller scale.

An article like this can get really long if I wanted to detail how to set up Wi-Fi on the Icom IC-705 to talk to the laptop with virtual com ports and audio cables, but there are great tutorials on YouTube which cover that already.  

The only issue I really ran into which continues to be a level of annoyance is that the "705" has such a broad front end that semi decent antennae can easily overload things, so backing the RF gain down is a good idea.  

Nearby strong out of band signals also are problematic and an external band pass filter will be needed for the 705 to perform better during group special events like Hudson River Radio Relay coming up in June..

Last year during that event, the 705 on the 6m band was useless when nearby 20m or 40m CW and SSB activity was taking place.

Not really sure if this article answered any questions for anyone, but it was fun setting this up for Winter Field Day and spending some time playing radio plus teaching others about how to set up a minimal self contained field station.

The perfect tape measure beam for RDF?

 

There are lots of instructions and videos about the 2m tape measure beam available already.  Here are some build ideas based on the different iterations I have built over the years which are originally based on Joe WB2HOL's version before he went SK.

Please visit: http://theleggios.net/wb2hol/projects/rdf/tape_bm.htm 

Mounting the directive and/or reflective elements

Rather than using small hose clamps to secure the elements to the boom, I originally used zip ties. This method worked well, but sometimes warped the elements at an angle.  Using electrical tape works better, is easy to replace, cuts down on weight and improves the radiation pattern of the antenna.

Using electrical tape is inexpensive, secure, neater and
does not influence the antenna pattern like hose clamps do.

Boom Material 

1/2 inch PVC T and crosses seem the best.  A few antennae I made used 3/4 inch conduit and junctions to improve ruggedness, but 1/2 inch has proven just fine and weighs less.  Only use PVC cement once you are happy with the construction to secure the junctions to the boom pieces.  

Friction fit construction may fail at the worst possible time, so glue your junctions.  The only real major benefit of 3/4 inch construction is that your elements can easily slide into them for storage or transport.  This is still possible with 1/2 inch fittings but is a little too tight and the elements will take up more room during transport.

Here is a 2 element version with the director and driven elements folded up.

Is a current balun necessary?

After making identical versions of  2 or 3 element antenna with or without the balun, I find the pattern of the antenna is more stable with the balun.   Making sure the balun is close to the feed point is a really good idea.   

I drill two pair of holes a few inches apart to form the balun and the feed point goes into the boom for a clean construction. Drilling the holes as far to the interior of the PVC cross is a good idea in order to leave room for folded element storage.

Where the nut inside the PVC cross is where a crimp ring slides over the screw and is the secured by the nut. Outside the PVC cross is a washer and nut. Outside and on the top of the driven element is a star washer on top of the hairpin match.



Scrap off the tape measure paint on both sides. Use a little De-Oxit to ensure excellent conductivity and to prevent any future rust. The 5 inch hair pin match is made from steel clad copper wire and crimp rings with the insulator removed are used to ensure secure operation. The crimp rings are also soldered to the hair pin match for further reliability.  A flat and star washer keep everything tight together.

How to connect your radio to antenna?

I like making a neat looking antenna and I route the RG-58 through the boom and out the back end.  You can make a long tail with a BNC male on the end to connect to your radio or via an SMA to BNC adapter.  Here is what a 3 element version of the antenna looks like configured that way.


The other option is a little more technically challenging to describe where a female BNC is fitted on to the end of the boom instead.  For the photo below, I also drilled a hole to secure a length of 550 paracord to act as a wrist strap of sorts.  

Using a short jumper cable to connect to the radio is needed, but when traveling, not having a cable dangling is a nice benefit and does not offer that much signal loss or leakage if done nicely.


Make your boom grippy?

Self amalgamating insulation tape works great as a grip and it wont leave a sticky residue behind if you care to remove it later. This same tape is also great for protecting antenna connectors, so pick up a roll or two and I am sure you will find many uses for this stuff. 

Here is a 2 element and 3 element 144 MHz tape measure beam antennae using similar construction practices. Put some electrical tape on the antenna ends to prevent potential cuts or eye pokes.

Measurements 

Many articles like the WB2HOL article cover measurements and you can find what works best for you. The goal of this article was to focus on some construction improvements.

When tuning the antenna it is best to adjust the driven element for lowest SWR at your operating frequency first and then add your reflector or directors after. This should lower the SWR further.

You can squeeze the hair pin match element to get a better match and as long as you are using stiff wire, it will hold its shape. The hardware used in construction of these antenna do not noticeably affect the radiation pattern of the antenna.

If you plan to transmit with these antennae, please ensure you adjust for a good SWR to protect your radio transmit circuitry.

Using these antennae

The original use for this design was for radio direction finding, but both will also do just for for transmitting if you are interested in light weight directional antennae for use with summits on the air (SOTA) or other portable operating scenarios.

Remember, that there is a null in signal off the back of the antenna and to the sides. This will be helpful when finding hidden transmitters.  The null is more pronounced with the 3 element version, but the 2 element design works great for other reasons.

If you are looking for a fun and inexpensive project you can build, please give these a try.

Hudson Valley Digital Network in conjunction with other area amateur radio clubs will continue to hold hidden transmitter hunts, so please check our activity calendar for upcoming events.


Safety first.  Be sure to protect the ends of your antenna elements with
some electrical tape to prevent injury

HR3:2021 Quick Engagement Results

Yesterday was the first annual Hudson River Radio Relay event. This year our fundraising theme was to support Bannerman's Castle Trust via GoFundMe and we managed to raise $1,418 in total with over $300 of that coming in the hours leading up to, during and just after the four hour event which took place from 1:00 PM to 5:00 PM Eastern US time on June 12th

While we await the final logs from all eight of our participating special event stations to get compiled and posted to the HudsonRiverRadioRelay.com website, an initial estimate from casual discussion with most all the participating locations sounds like we should end up around 500 to 600 total contacts as a collective group.

There are so many positive things that will get mentioned about this event that will get published in the coming days along with lots of pictures and videos, but here is a quick snap shot just based on who visited each special event web page as well as the QRZ.com page for each of our eight callsigns.   

Both metrics were measured from between May 13th and June 13th at 10:00 AM EST.


It was expected the N2B station would possibly gain the most attention as a never before activated USIAP island NY047, but the N2O station rivaled our flagship location mainly due to its various USIAP, COTA, POTA and SOTA designations along with an amazing number of enthusiastic members that promoted what they were doing.

Our three stations that were not aided by affiliation of the different "on the air" categories like islands, parks or summits such as N2H, N2S and N2V seem to have also been very popular too over the last 30 days of measurements and deserve a lot of credit also.

The three lowest elevation stations, some only a few feet above the river such as N2U, N2D and N2N are hidden gems that deserve much more attention considering how hard they worked and are all actually very rare locations that we need to help promote even more for next year. 

Between these three stations, there was a brand new USIAP NY-073 on a US Army facility plus POTA K-2079, K-4582, K-5161, COTA K-00825 and the former home of the founder of Paramount Pictures.

What's Next?

Now that we have an official website visit metric posted just after the event, please go and learn more about each club and location they operated at during this special event by visiting HudsonRiverRadioRelay.com 

More detailed articles from each station highlighting each sponsoring club and a list of total event contacts plus the winner of our Xiegu G90 package raffle will be coming soon, so please follow the HVDN blog for more details between now and ARRL Field Day which is just under two weeks away.

Please give 17m a chance....


With nice weather finally returning, its time to take some green pictures of some outside operating compared to the last still frosty excursion with the Icom IC-705 promoting some upcoming combined IOTA, SOTA  and POTA activity here in the Hudson Valley via the Hudson River Radio Relay event on June 12th.

After some portable antenna discussion with Nolan KE8JCT who will be a guest presenter on HVDN Live scheduled for May 17th at 8:00 PM Eastern US time, I was tempted to build an even lighter antenna out of some really nice yellow Teflon 24 gauge wire acquired from the local candy store known as P&T Surplus.

While Nolan will be talking about the recent USMA Balloon Sat in a few weeks time with us, he is also very interested in portable operations and CW QRP!

There is a growing number of portable focused operators in the Hudson Valley like myself, Nolan, Jonathan KC2BNW and a number of others interested in the convergence of radio and the outdoors.


With a freshly mowed and goose poop free lawn for the moment at casa de K2GOG, I set up my just constructed "Lazy Linked Inverted L" to see how well it would work on 17m.  I needed a back up antenna for my pack and this seemed like a good idea.

This antenna which is supported by the 20ft version Jackite pole in orange is supported by a simple $4.99 Tiki Torch stake at the bottom with a piece of PVC that the pole slides over.

Dimensions for the simple 52 foot long chunk of yellow wire is as follows:

  • 40m Band = 52 feet, plus 12 foot counterpoise, half wave, medium Z
  • 30m Band = Link at 46 feet, half wave, no counterpoise, high Z
  • 20m Band = Link at 33 feet, half wave, no counterpoise, high Z
  • 17m Band = 52 feet, full wave, no counterpoise, high Z
  • 15m Band = 46 feet, full wave, no counterpoise, high Z

The SWR was about 3:1 on 17m, but the magical ZM-2 antenna tuner got things quickly under control at 1.2:1 to help maximize my 5 watts of RF outwards on 18.1575 MHz.  The "long" end of the antenna not visible in the picture was tossed into a nearby tree.

Admittedly, my first contact with this antenna had a much better station down in Texas that probably helped a little, but a contact is still a contact. QSL? YES!

Tom K5VWZ has a world class station and was able to pick me up out of the noise as documented by the recording function on the IC-705. 

I really like this feature and how flexible it is, but to get the file off the radio still means I have to remove the SD card from the radio which is sort of annoying so I could trim it and convert to an MP3 to share with y'all in this article.

While this was far from an optimal antenna for 17m band and a dipole would have probably done much better, its still always amazing what low power communications without the internet can accomplish.

17m is your next challenge

Be sure to keep an ear on 18157.5 kHz USB as it is known as the 17m HFPACK calling frequency where portable people like me are likely to pop up, but usually not from the backyard.

During the upcoming Hudson River Radio Relay event next month,  expect to look for N2B located on Bannerman's Island (USIAP NY047) which has never been activated by radio before and also N2D, which will be operated by the United States Military Academy at West Point on Constitution Island that now has been awarded USIAP NY073 thanks to this event and its goals.

A few of the eight participating stations like N2B are also technically going to be part of Hudson Highlands State Park K-2079 which actually counts as separate parks such as K-5161 and which you will hear N2U operating on thanks to the PEARL club.  The Orange County Amateur Radio Club operating as N2O from K-2010 and possibly K-2081.

There is much more happening too, so hopefully this article excites you about 17m and some MAJOR upcoming activity across the Hudson Valley.

The perfect Icom IC-705 case?


Will this post address every possible need that everyone may have when using the Icom IC-705 at home, in the field or on a picnic table?  Probably not, but I think this comes awfully close to meeting my needs so thought worth sharing my journey.

How do I want to use the Icom IC-705?

After acquiring this radio, I spent time getting familiar with its functions and watching what accessory purchases others were making.  

Lessons learned as an early Yaesu FT-817 purchaser almost 20 years ago proved that spending more than that radio cost for addon's got quickly out of hand.

And, since the Yaesu FT-817 brand new back in the early 2000's was much less than the Icom IC-705 today, I wanted to go about things a bit smarter this time around.

My intended use cases for the Icom IC-705 are as follows:

  • Toss it in the backpack for easy to deploy legitimate field operations in rough conditions.
  • Perfect vacation and traveling demo "shack in a box" scenarios to excite new prospective hams.
  • Fill the "If I could use just one non-handheld radio" use case...
As a QRP enthusiast, I am fine with 10 watts RF output on all bands with external power or 5 watts on the internal battery. I also do not mind no internal tuner as I usually use resonant antennae for specific uses cases like satellite, digital modes and SOTA. 

Case:  The cornerstone of all accessories

Someone did the hard work already and shared this on the Icom IC-705 Facebook User Group, so I purchased this enclosed hard case for reasons explained later compared to a soft or protective rail case. 

Cost was $12.99 USD for the large size case in orange on Amazon and is made in the USA.   Purchase link:  MTM Survivor Dry Box with O-Ring Seal




The Icom IC-705 fits perfectly in this case and offers some extra room for a few basic accessories such as the wired microphone and a VHF rubber duck antenna or small end fed wire for HF.  The extended BP-307 battery fits just fine and that lives full time inside the case now attached to the rear of the radio.


Case Access:  Before making holes for antenna stuff

The MTM case is a dry case, which means your expensive radio wont get wet or screen scratched when its inside this protective cocoon.  I am not going to say its waterproof, but it feels like I would not have a moisture issue so will call this case weather tight instead. 

Since you can pretty much operate the Icom IC-705 fully remote using software or a mobile device described later, I only wanted to make a external holes for antenna and power wiring.  

First thing you need to buy is a BNC cable that has a right angle male on one side and a female BNC bulkhead on the other.  Spending $9.49 USD, the Eightwood BNC Bulkhead Female to BNC Male Right Angle Adapter RG58 Cable 50cm /1.6 feet is what I settled on.

The length of cable also solves a counterpoise issue on the two meter band since using most standard HT antennae with the IC-705 do not work well, so this is a hidden benefit. 

The right angle BNC male is what connects to your radio. A straight BNC will be too long to go inside the case. This is why having a right angle is needed. If an easy to source right angle bulk head was available, I would have went for right angles on both sides to give me even more flexibility.

Carefully placing and putting a hole in the side of your MTM case is important, so measure twice and cut once!  

You want to avoid the straight part of the BNC bulkhead cable hitting the side of the radio inside the case. It is best to make your entry hole as indicated in the picture below.



You may notice a nice binding post next to the new antenna connector. This also has a hidden benefit since you will find you need a grounding point on your radio to connect a counterpoise for HF operation to your radio.

Purchase  Jabinco 2pcs Gold Plated Insulated Terminal Binding Post Power Amplifier Dual 2-Way Banana Plug Jack for a total of $4.99 USD and you will end up with 3 spare terminal posts you can use for some other project, like some type of portable balun.  Or, you may have a spare binding post left over from another project you can use instead, but this one is very high quality and I recommend this.

Using one of these posts will give us a ground connection to the radio. You can either use some bare copper wire or a thin piece of sheet metal with appropriate holes drilled to connect this binding post to the outer conductor of the BNC bulkhead on the inside of the case.

Be sure to tighten up your connections correctly and you now have a case with external antenna connections that are weather tight and be sure to test that your ground lug and antenna port are now connected by using your continuity function on a multimeter. You should have close to zero resistance.

Case Access:  Adding power 

It would have been nice to just use Power Pole connections for power, but they take up more space inside the case and some may require more complicated hole making, so using the "standard" 5.5mm O.D.  x 2.5mm I.D coaxial power connector which the IC-705 and the Elecraft KX2 and KX3 uses seemed like a better low profile idea. 

There are also many external battery packs and inverter generators that use this same connector, so I am not worried about interoperability too much since this is a lower current connector and the additional benefits of the Power Poles are not needed.




You will need to drill your hole carefully as pictured and then you will need to solder on a male right angle 5.5mm O.D.  x 2.5mm I.D coaxial power that will connect to your radio after you pass the free ends into the dry box case.

If you want to add a reverse polarity protection diode or fuse, I will leave that up to you since the IC-705 does not offer much protection if you plug in your external power the wrong way.

When using a diode like a Zener type, be sure to realize that some voltage drop may occur from your external power source. For the Icom IC-705 to give you maximum RF output, the below chart will help you.


The internal battery pack is only capable of 7.4 volts, so to get that extra kick of RF output, you need to be over 12.5 volts always if you need that extra tiny bit of decibels to make radio contact.

If you need to connect power poles, you can use a ready made cable like this one by Windcamp for $12.99. 

How to access the IC-705 now?

This is not yet a perfect solution. You will need to find a way to secure the IC-705 inside your case which may require bending a piece of sheet metal to make a bracket that can screw to the underside of the IC-705 and you can then Velcro the radio into the case.  



You can also decide to skip that construction step and ruin your radio by putting Velcro on it or your battery directly.  This is left up to you on how you like to do things. 

This really good Velcro allows for easy removal of the IC-705 so you can access the SD Card, USB port, keying jack or the other connectors you may care about.  

Icom has not enabled a way to access the SD card over Wi-Fi or Bluetooth via FTP or anything else should you want to grab screen captures or audio recordings from the radio.   

You can also not access those files over USB either, so this is one reason why you will need to remove the IC-705 from the case.

The other connectors for my personal use cases were not important, but if they are for you, that is up to you to solve for. 

I would however think to maybe add an external USB in the future if I can find a suitable connector for times where I do not thing that low power wireless signals like Bluetooth or Wi-Fi are appropriate but wish to still control the radio remotely.













Everything else can be done "almost" over bluetooth or Wi-Fi

Control of the radio can happen over bluetooth or Wi-Fi for different reasons. Using a bluetooth microphone solves some issues for portable voice operation but adds additional "how do I charge the bluetooth speaker complexity", so keeping the wired mic on hand is important.

I am only plugging in the microphone connector and not the speaker part of the hand mic. This will not impact if you use a bluetooth mic or digital modes.

If you want basic remote frequency control, you can use the 705 Remote application on Android or the free Icom RS-MS1A application.   

The Icom Android application will appeal more to those who want to use D-Star and related advanced functions where the 705 Remote by Ikeda Shogouki may be better for those looking for a classic VFO knob and more HF focused functions.  

The popular Dan Toma Pocket TXRX software does not yet support the IC-705 and your results will be mixed when using different CI-V addresses to try and use profiles meant for radios like the IC-7000, IC-7100 and IC-7300. For now, I am ignoring this otherwise great software and its capabilities.

Remote radio versus remote internet control operation

The prior mentioned basic remote setup will not offer much else than basic remote radio capability.

If you are looking for complete wireless control of your Icom IC-705, you will need to purchase the  Icom RS-BA1 software for about $120.00 USD that runs on a Windows computer or some other platform with containers or virtual machines. 

This Icom software allows you to use your radio totally remote from your computer, including virtualized COM ports for digital modes, audio and CAT operations.  

You can also use RS-BA1 to allow other software like FLdigi, WSJT-X or Ham Radio Deluxe to control or talk to your Icom IC-705 if you are interested in digital modes and wish to operate the radio remotely. For voice communication, you can use a headset or microphone with your computer.

One use case for this is putting your radio at near your portable antenna and then take your laptop to a comfortable rock or picnic table.   This way you can minimize feedlines which takes up more space and weight in your pack, if you are interested in portable operations and are not afraid of short range wireless signals

You can create a point to point Wi-Fi access point (AP) with the Icom IC-705 to connect your laptop to without the need of the internet for this type of use which is very nice.

Alternatively, if you do have internet access and wish to share your IC-705 over the "world wide web" from the field, you can do that instead by changing from AP mode to a regular Wi-Fi profile. 

If you are in the field, allowing the IC-705 to connect to a broadband hotspot or possibly an AREDN mesh network is possible.  You still need to use the Icom RS-BA1 software for this to work.

A second option, not requiring the expensive Icom software is brought to us by Norbert Varga and team via a workaround that can run on a Raspberry Pi and act as a form of  a "man in the middle" server that will bridge a computer and the IC-705 over Wi-Fi to make a server.  This may require some advanced setup to get it working if you are not very skilled with Linux. 

A link to this software and instructions are here: https://github.com/nonoo/kappanhang

While this works great, I would not recommend this if your goal is less complexity in a field environment since it means transporting a raspberry pi and power source for it which if bought new, getting the Icom RS-BA1 software may be a better long term solution. 

A third solution is the very excellent Win4IcomSuite by VA2FSQ. His software is less than half the cost of the Icom RS-BA1 and offers nearly all the same functions but also allows for better integration with other software such as digital mode or satellite related programs. This may appeal to those who do NOT want the Raspberry Pi solution complexity.

Summary:  Case closed?

Everyone has an opinion and I am not claiming this is a perfect solution for everyone, but it does offer complete protection of your expensive radio and offers the ability to use it in the field with a good degree of safety.  

Here is a list of things mentioned in this article if you wish to buy it all from Amazon Smile, which a tiny part of proceeds benefits the Overlook Mountain Amateur Radio Club.

What's in the bag? EDC & SOTA Tips from KC2BNW

 



Another excellent video over on The Farmacy Seeds Network highlighting more convergence between the outdoors and amateur radio.  Jonathan KC2BNW last appeared on CJ  KD2IIN's show when he was remote at Sam's Point in February and joined by Steve K2GOG at home.

Following that video where Jonathan showed us his gear in use, Steve took us on a tour of some of his kit.  To go one better (maybe even three better),  this latest TFSN episode goes into depth on every day carry and field pack organization.

Be sure  to watch the first hour for things not related to amateur radio, but the below like will get you right to radio focused discussion if that is what your more interested in.

UPCOMING 3/15/2021 HVDN:LIVE - VHF/UHF is NOT just FM Repeaters: The IC-9700 & IC-705 Punch-Out



On the 8:00PM EST March 15th 2021 episode of HVDN:LIVE, we will take the Icom IC-9700 and IC-705 for a in depth conversational review thanks to Neil W2NDG as moderator with Jim WA2UMP and Steve K2GOG trying to defend reasons why to or not acquire either of these radios.

VHF/UHF is NOT just FM repeaters

This review is not going to be a product endorsement in any way, but it just so happens that both of these radios do not have any direct current production competition, so that is why we are stuck with making this an Icom focused discussion. 

The goal will be to highlight all the interesting things you can do on VHF/UHF aside from only talk on repeaters.

Both the Icom IC-9700 and IC-705 will be in full view during the discussion to ensure we provide fact rather than fiction for both radios. It will be really fun! 

Basic flow is going to be:

  • Introductions 
  • Reasons why did Jim acquire the Icom IC-9700  
  • Reasons why did Steve acquire the Icom IC-705 
  • Discussion on if they would do it again
  • Discussing "Was it easy to do...…" 
  • Focus on hardware tips & tricks
  • Focus on software tips & tricks
  • Remote operation comments 
  • Live Q&A

How to join HVDN:LIVE?

We are going to experiment and see how many people can join the live meeting and we will be using  Jitsi instead of Zoom since HVDN supports and encourages open source projects.

If interested in attending on March 15th at 8:00 PM Eastern Time , please join using http://meet.jit.si/hvdn/livemarch15th2021 and use the password "hvdnlive"

This event will be recorded for later playback, but anything live is always better than a recording, so be sure to check it out and get your questions ready for Neil, Steve & Jim! 

Feel free to drop some questions below in advance!

Prepping for SOTA: Field Report and Gear Dissection


Live from high on top of Sam's Point (W2/GC-020) were brothers Jonathan Gong KC2BNW and Michael Gong KC2BNX at the 35:00 minute video mark of this great interview focused on how to integrate amateur radio into outdoor activities or find ways to take your "ham radio hobby" with you as part of "Summits On The Air" or SOTA for short.

Steve Bossert K2GOG shares some background about radios that might be good for "prepper" or other emergency communications for the first show segment and then Jonathan shows them in real life use.

Later on in the show, Carlton made Steve empty a few of his packs to talk about some of the non-ham radio things to consider when out in the field.

Major topics were staying hydrated, organized and illuminated along with communication tips.  Not covered in this episode are details are anything related to staying warm.

Video below starts at about the 90 minute mark, so if you like what you hear, go ahead and jump backwards for the full video.   Even a brief mention of BlackHat and #DEFCON as a way to tie together hiking, cyber security and ham radio come up via a special "Ham Village" Velcro patch courtesy of Joe Cupano NE2Z.

Please follow "The Farmacy Seeds Network" for future videos with Jonathan, Mike and Steve.  You can even buy a really cool TFSN mug for home use to help support the channel.

6 Hudson River islands & a mission....


The Hudson Valley of New York gets its name sake thanks to the 315 mile long Hudson River. which starts in the Adirondack Mountains and empties out into the Atlantic Ocean between Manhattan Island and Jersey City.

There are only six present recognized islands in the Hudson River but many former islands that have been lost thanks to human based expansion. 

Over the last 200 years, islands which were close to shore were reattached to the mainland by filling them in with construction debris or earth materials to help make room for rails, bridges and roads.

As of 2020, the remaining official six islands of the Hudson River are:

  • Schodack Island
  • Esopus Island
  • Pollepel Island
  • Constitution Island
  • Iona Island
  • Hudson River Islands Park

HVDN & Islands


When Hudson Valley Digital Network was formed in 2017, the goal was to find areas of convergence between wireless technology and other hobbies. 

The word "convergence" is referenced many times across our website, other articles and presentations. 

This article will help share a great example of convergence thanks to these six islands and some ways that area outdoors enthusiasts and conservation groups can work with amateur radio aficionados to broaden the reach for needed donations related to the upkeep of these island treasures.

Esopus Island, Iona Island, Constitution Island, Bannerman Island, Pollepel Island

Lets explore some history of these six islands and why they matter to the future of the Hudson Valley and the evolution of amateur radio activities related to these treasures and extending to other destinations in the future like the man made Walkway Over The Hudson and our many peaks that flank either side of the mighty Hudson River.

Schodack Island

This 1,052 acre island is actually no longer an island since it became a continuous peninsula in the early 1900s, but its still called an island, just like New York City's famous Manhattan Island which some may call a peninsula too. 

A small land bridge at the north end of the Schodack Island now connects it to the mainland, while the New York State Throughway Connector passes over the island and links I-87 and I-90 together for more efficient transportation. 

Before a federal government project dredged up material from the river to create deeper water navigation, Shodack Island was actually six islands. 

Schodack Island
Going back to the time before Europeans had settled in the area in the 1500s, the native Mahicans called the area home and was considered a major settlement area dues to its abundance of life sustaining animals, fertile farming conditions, access to fresh water and natural security brought on by the river.

Little Shodack Island, Moesmans Lower Schodack Island, Mull Island, Houghtaling (Schutters) Island, Schodack Island and Mull's Platt are the six islands that now are simply referred to as Shodack Island. The only free standing island of Schodack is the tiny Little Schodack Island.

In 2002,  Schodack Island State Park was created to help maintain its conservation and enjoyment.  

This relatively large island has parts that span Rensselaer, Greene and Columbia Counties.  The island is also located in what is known as grid FN32 for those interested in a really short international standard way of defining a location using the Maidenhead Locator System.  Schodack Island also can be known as K-2136 thanks to the "Parks On The Air" initiative.  Unfortunately, Schodack Island is not part of IOTA or USIAP. 


Esopus Island

Compared to the expansive Schodack Island, the much smaller Esopus Island can be found in Dutchess County and is roughly 1500 feet long and 120 feet wide. The Lenape native American tribe had made use of the island for centuries and prior to its current name, Esopus Island was once known as Pell Island dating back to the 1800s.

While now uninhabited and under the control of the New York State parks system, back in 1918 there was a Mr. Aleister Crowley who spent 40 days and 40 nights on the island, who has a somewhat sordid story himself involving the occult and magic.  

K-2101 POTA Esopus Island
There is some further mystery surrounding this island, including its stone boat house and a small million dollar cottage on nearby private Bolles Island, which is considered part of Esopus Island under the same park system name linked to Mills Norrie State Park. 

Sadly, Esopus Island is not currently recognized as an "Islands On The Air" destination, but it is part of POTA thanks to it being officially part of Mills Norrie Park (K-2101), where you can launch a kayak from if you wish to access the island. It is also part of the US Islands Awards Program.


Pollepel Island

This rocky island is also more famously known as Bannerman's Island and is also located in Dutchess County.  

Before it was purchased by Francis Bannerman VI in the mid-19th century, the island was already part of American history as a defense point during the Revolutionary War where "chevaux de frise" were put in place to help slow down British military ships.

Following the American Civil War and the later Spanish-American War, Mr. Bannerman purchased surplus military equipment and he needed a place away from population centers in New York City to store the more "explosive" merchandise in his inventory.

In 1901, Bannerman started construction on his newly acquired and soon to be island fortress.  A castle like structure was built to hold over thirty million munition cartridge's and his name was boldly painted across its widest wall, some of that lettering can still be seen over a 100 years later.

















The same year that Mr. Crowley was squatting on Esopus Island, Mr. Bannerman passed away and two years later in 1920, a large explosion destroyed much of Bannerman's Castle.  Luckily, no one was injured and the family residence building was not harmed since it was located further away on the island from all the arsenal remnants.

Fires and natural conditions have started to reclaim parts of the magnificent buildings, but the Bannerman Island Trust which was formed to protect this national landmark has helped maintain what is left for future generations to enjoy.

While Bannerman/Pollepel Island is now also considered part of the New York State park system, it is not qualified as part of IOTA, but is registered as part of USIAP, but not activated.

Via the core mission of HVDN, we seek to not only change this, but to do so in a way where this historic site will be able to benefit through the generosity of amateur radio enthusiasts wide reach that many do not really think about to help with needed donations.

The bigger challenge is explaining how we will do this, so please keep on reading.


Constitution Island

The name of the island is directly related to our rich regional history and is the only part of the famed West Point U.S Military Academy to be located on the eastern side of the Hudson River.

This island was home to the earliest of the Revolutionary War fortifications and now includes an amazing educational center which details the last 250+ years of natural and human influenced history. 

Constitution Island is home to the important conservation center known as Constitution Marsh Audubon Center, which is a hidden gem along the shores of the Hudson River and nearby the famous Boscobel House and Gardens.

Just like Schodack Island, its possible to access some of the Constitution Island property without needing a boat and this is thanks to a series of walk ways that spread out into the marshlands funded by donations and built by volunteers. 

While almost everything in the surrounding area is considered as historic as you can get in American history, there is no official Parks On The Air,  Islands On The Air or US Islands Award Program designation for this fantastic day trip destination located in Putnam County. 





















Iona Island

The only major island on the Hudson River that is part of the western shore county of Rockland, is Iona Island and is officially part of the USIAP via its NY022R designation. While this island sometimes is referred to as a stand alone park, it is actually part of Bear Mountain State Park.  

Until 1947, the island was used as a Naval Ammunition Depot and has since been added to the National Natural Landmark register in 1974.

Iona Island is part of the POTA program with its K-2081 designation, but is not part of IOTA.  This island located in grid FN31 is also very close to FN21 nearby, which may interest those interested in grid chasing expeditions, another popular amateur radio activity.

Hudson River Islands Park

We close this journey along the Hudson River with the most unimaginative named island on this important waterway, which also holds the POTA designation of K-2080.

This state park is located in Greene County and is comprised of the Stockport Middle Grounds, the Middle Ground Flats and Roger's Island if you were wondering how did this park get the name. Roger's Island has USIAP NY043P status.

The downriver Esopus Island is not the only island to have a history of those looking to have a temporary island home, but the scenery certainly makes one wish to spend an extended time here, especially in the warmer months in part to its natural beauty in Columbia County.

A second POTA designation exists for the same park, which is pretty rare plus it is also part of USIAP too, making this a triple threat activation or reason to visit by boat, car or bike.

The Middle Ground Flats has K-5417 assigned to it and if you have a boat, its possible visit and make an additional POTA activation that technically should really be an island, but is not recognized by IOTA or USIAP.


Explaining IOTA & POTA Importance

Unless you are an amateur radio enthusiast already, the constant reference to IOTA, POTA, grid squares, chasers and  activations may have been confusing.  

The reason why explaining this last was important and hopefully draw you into something interesting without getting super technical right away, but hopefully you noticed the many hyperlinks you can go back to visit.

Most people associate amateur radio with people spending late nights in a dimly lit basement conversing via Morse code on big radios that have ancient vacuum tubes inside them.

While that image may have been true overly 50 years ago, much has changed in the radio enthusiast hobby which now encourages the ability to get outside and play radio from temporary locations with very modern equipment, a DIY kit or something entirely homemade.


Various recognition awards exist which "gamifies" the ability to either make contact with many other POTA or IOTA based stations or even get out and allow you to become the sought after station yourself.

It is very easy to obtain a General class amateur radio license which permits almost all use of the  "high frequency" 1.8 to 30 MHz spectrum used that amateurs and make wireless contact without the need of any network for long distance communications.


An example station used by Don WV1W is pictured and who also has a great book available for purchase with lots of helpful tips to get started with POTA and related operating activities. 


There are actually other ways to activate parks, islands and even summits on the air (SOTA) using satellite communications capabilities or even simple hand held radios too on the VHF/UHF bands. 

An example is Steve K2GOG who is shown with handheld radio he used to make contact with others from on top of the fire tower in his background since space was limited and did not allow for larger HF antennae at the top of the tower!

Amateur radio offers something for everyone and if you like talking with other people about your recent hikes, bike rides, geocaching adventures or country side strolls where you may end up painting or sketching your destination, imagine the discussion you may start with a fellow human when they ask you about your radio equipment when trying to make contact with other people.

How can IOTA, POTA & XOTA help great causes?

If you have ever participated in different walks or events to raise awareness and donations to support great causes like Wounded Warrior Project, National Alliance for Mental Illness (NAMI) Walks or Relay For Life; its possible with amateur radio to open up new possibilities in creating awareness on a much greater scale and beyond just your local community.

For over 130 years, amateur radio operators have sent each other commemorative keepsakes called QSL cards.  These postcard sized tokens often include a special photo on the front and contact details such as time, date, frequency and location on the back.














During certain contests or special events, sending a small donation to support the event in question, would certainly motivate who you contacted to send you a QSL card.  

In the past, for those extra rare contacts it was even common to mail ahead some extra stamps or something called an international reply coupon (IRC) to help offset return reply costs.

If local communities of amateur radio operators and the clubs they are members of can help raise exposure for great causes like Bannerman Island conservation through a special event activation, it should be easy to raise funds via a donation page where the contact can be confirmed and a QSL card be mailed out.

2021 Resolution: HVDN GO:GREEN Initiative

Using the Hudson Valley Digital Network callsign N2HVD, we expect to schedule an official activation of Bannerman Island in the May/June timeframe.

The 1st initial planning meeting among area amateur radio leadership took place in December and will meet monthly to help organize efforts and to engage in advance with other organizations who may wish to help make the event a success. Things we will be looking for include, but not limited to:
  • A uniquely designed QSL card to commemorate the event
  • Help with a donation landing page, with all proceeds going to Bannerman Island Trust
  • Willing and capable radio operators interested in a boat journey to the island
  • Assistance with marketing and advertising of the event
  • Other area communications and well wishes for success
