FreeDV Day, February 19, 2022, 1700Z

January 27, 2022 By Dan KB6NU Leave a Comment

This was recently posted to /r/amateurradio. I’ve always wanted to try FreeDV, and it’s supposed to be relatively easy to do with my Flex 6400. This seems like a good opportunity for me to get this all working and make some contacts……..Dan


If you’ve ever wanted to try out digital voice on HF, check out the upcoming FreeDV Activity Day!

I’m one of the maintainers of the FreeDV project and have been working on getting more activity on the bands as of late. Back in early November, we had our first Activity Day and it resulted in the most simultaneous FreeDV users in quite a while, so we figured we’d make it a quarterly thing from now on.

Speaking of making it quarterly, the next Activity Day is going to be from February 19th at 9AM PST (1700Z) through February 20th at 8:59AM (1659Z). There’s no limitation as to what FreeDV mode is used (these days, typically 700C/D/E and 2020) and definitely no obligation to log or submit anything after the event. Think of it more like the monthly JS8Call QSO Party than anything. :)

For reference, here’s where FreeDV can usually be found:

  • 80 meters: 3.625, 3.643 or 3.693 MHz
  • 40 meters: 7.177 MHz
  • 20 meters: 14.236 MHz
  • 17 meters: 18.118 MHz
  • 15 meters: 21.313 MHz
  • 12 meters: 24.933 MHz
  • 10 meters: 28.330 or 28.720 MHz

Of course, those aren’t the only places that it can be found. It’s typically allowed anywhere SSB voice can be used (minus 60 meters), at least in the US anyway. The QSO Finder and PSK Reporter are great sources for finding contacts, whether during the event or any other time.

Anyway, we’d definitely welcome more participation. If you have issues setting up or using the application (or SM1000 if you happen to have one), definitely leave a comment here or on the digitalvoice reflector and I or others can help resolve those.
