Upcoming Events

We’ll be at the Summer Gathering in North Bend WA this weekend (Sep 6-8) talking about changes to the FCC Regs and how that affects the UDR56k.

Then catch us at DCC in Seattle, after which we’ll release our progress update.


John will be presenting at Pacificon, October 12-13 in Santa Clara CA.

He’ll be talking about low-cost computing platforms for D-STAR and packet radio as well as the UDR56K. Stop by if you’re in the area.

A Hailing Channel for Packet Radio

Just gave a presentation here at DCC on declaring a single channel on 440 as a hailing channel, then QSYing to one of the other packet channels to handle traffic like email.

I thought this might be a natural way to bridge APRS and Winlink, but was nervous about the response from APRS users about using their channel.

Imagine my surprise when I asked the audience what frequency we should use, and none other than Bob Bruninga said:

“Use the APRS Frequency, that’s what it’s there for.”

Be sure to read Bob’s comment as posted on the APRSsig.

The video of the presentation was done by Gary at HamRadioNow and will be posted on the TAPR website.

Catch John on the PAPA Net

The PAPA System ( has invited me to participate on their net this Thursday the 7th on D-PLUS REF012C at 8PM Pacific (0300Z).

Apparently there is a lot of discussion about the UDR56K in Southern California.

I will be giving a general overview of the genesis, technology, and applications for the UDR56K, followed by a Q&A for net check-ins.

Since this will be “on the air” over amateur radio, I will not be able to provide any responses to questions related to sales or support.

The net can be accessed for check-in on REF012C. REF012 is also available as an audio feed at
