Technical Advisory Committee (TAC) Update

Jon Kemper (KA6NVY) headshotThe TAC has been working on refining 44Net VPN server technology as part of the ARDC PoP project. This resource will allow a ham to quickly request a static IPv4 or IPv6 address and automatically generate Wireguard VPN keys to use with an OpenWRT router. This can be useful for remotely accessing equipment such as a repeater controller, SDR, or RaPi when connected through CGNAT Internet networks. The PoPs are currently set up in Atlanta, Frankfurt, and coming soon to Los Angeles. For more information or to become a beta tester, please email

What ARDC Has Been Up To

Jon Kemper (KA6NVY), John Hays (K7VE), and Tim Tim Požár (KC6GNJ) at the Amateur Radio Digital Communications (ARDC) booth at Pacificon 2023This month, Jon Kemper (KA6NVY), John Hays (K7VE), Tim Požár (KC6GNJ), and Board member Phil Karn (KA9Q) attended Pacificon 2023 in San Ramon, CA. Local GAC members Judi Clark (KK6ZCU) and Don Prosnitz (N6PRZ) also dropped by. They were all able to interact with our community at our booth, where many of our grantees – including MMDVM, M17, FreeDV, and Bay Area Mesh – came by to visit. Visitors to the booth also got to see our demo of a 44Net VPN router, which was a hit! At the ARDC Forum, John gave an overview of the ARDC Grants Program, and Jon provided a report on the recent advancements of 44Net, which include improved access and management tools. Grantees and 44Net users that attended the Forum were invited to share their respective experiences. This was a fantastic event: the Pacificon organizers did a great job of ensuring that our needs were met as exhibitors, and we look forward to attending Pacificon 2024.

ARDC Team Spotlight

This month’s spotlight will be highlighting GAC Chair Bob Witte (K0NR) and TAC member Zach Seguin (VA3ZTS).

Regarding the grant proposals that have come through ARDC, Bob says “I have really enjoyed looking at all of the great ideas that have been proposed and being part of funding a large portion of them.” Outside of ARDC, Bob is also a contributor to, a site dedicated to helping people get their amateur radio license and enhance their operating skills. In addition to his volunteer work, Bob is either at home in the mountains, establishing a VHF/UHF ham station or enjoying the outdoors with his wife Joyce (K0JJW), summiting mountains in Colorado or traveling to parks in North America while completing SOTA or POTA activations along the way! You can learn more about Bob by checking out his personal website,, where he makes many posts about him and Joyce’s SOTA and POTA operations while enjoying the outdoors.
