This event has a little something for everyone interested in modern technology and applications, not just related to amateur radio or even computers.
The featured keynote this year will be led by Tony Sager of the Center For Internet Security which is headquartered just outside Albany, New York. Tony will talk about the importance of cyber-security and how it affects almost every aspect of our connected lives today.
Other featured presentations include:
- The State of Cyber Crime in New Jersey by NJ Department of Homeland Security Cyber Team!
- Maintaining the Integrity of Elections in a Digital World – Rebecca Mercuri
- Quantum Computing – Barry Burd
- Amateur Radio Satellite Spectrum - Steve Bossert
- WordPress Bootcamp – Lou Judice
- Cybercrime and Theremin Zen – Kip Rosser
- MMDVM Hotspot Construction - Joe Apuzzo
What about amateur radio?
- Hands-on Arduino Workshop for Beginners – Katalin Frolio
- All Day Robotics Pavilion – Seung-yun Kim
HVDN's very own Joe Apuzzo N1JTA and Steve Bossert K2GOG will be among the 50+ presentations and workshops also taking place during this fantastic event.
In N1JTA's 30 minute presentation he will talk about how radio and computers has converged through the popularity of digital modes in Amateur radio and how it has grown exponentially over the last few years due to the affordability of VHF/UHF digital handheld radios and other equipment.

is full duplex capable and the same size as a Raspberry Pi Zero. |
A large part of this growth can also be attributed to the impact of hot spot devices and the unique learning capability they create. A hot spot is a small access point type device that uses amateur radio spectrum and a decentralized network of servers to enable global or local digital communication.
Joe will cover at a high level, what is needed to construct your own "micro repeater" or hot spot device and how it works, along with how to create secure connections and utilize a decentralized network maintained by a group of amateur radio operators around the world.

| Brandmeister is unique in that it can route all types of digital voice traffic through its decentralized network of servers to end node devices such as hotspots and repeaters |
Since the hot spot device is nothing more than a Raspberry Pi single board computer and a multi mode digital voice modem hat plus some open source software called Pi-Star it is relatively inexpensive but very complex to understand how it works.
Steve will be cover in varying detail more than 21,000 MHz of spectrum available to amateur radio operators looking to experiment with satellite communications today. While much of this spectrum is above 1.2 GHz, this still leaves over 60 MHz of varied spectrum that can be used by those holding the easiest to get Technician class amateur radio license and with minimal expense.

| Your DMR radio can also be used for satellite communications via analog FM mode you might have forgot exists. |
Steve's discussion will cover the most common spectrum used today for amateur radio operators interested in satellite communications, additional spectrum users to be mindful of and a review of the most active satellites that can be used with less than $100 of invested equipment. He will also give a "sneak peak" on this topic to attendees of the March 11th HVDN meeting in Rhinebeck, NY.
