While I own several DSTAR radios and enjoy that mode, I am rooting for the adoption of FreeDV as the digital codec of choice on HF. I have written about FreeDV before. It is a truly “free” CODEC that anyone can use without licensing fees. If you have a computer with speakers and a microphone AND a separate sound-chip interface like the Signalink USB, you are set for operation. Just pick up the latest version from http://freedv.org/tiki-index.php for your Windows, Mac, or Linux PC. FreeDV requires TWO sound interfaces. For example, the computer microphone will be digitized by your soundcard and converted back to analog on your Signalink output to the radio. Likewise the incoming radio audio will be converted to digital by the Signalink input and converted back to normal audio by your soundcard/speakers.
All you have to do is set up these pathways in FreeDV and get on the air. Since the mode is pretty new it can be difficult to stumble on to QSO partners. For that, John Hays created a neat online chat utility at http://qso.k7ve.org/ where you can see a live list of FreeDV ops and set up an instant sked. I made my first FreeDV QSO this afternoon with a station in Seattle on 40 meters, followed by a perfect copy from a Florida station on 10 meters.
It is digital but it is voice, so you need to operate in the phone sub-bands, not CW. Give it a try.

We only had three candidates take VE exams today but they all passed and everything went perfectly, thanks to Bruce, Don, Scott, Claire, Jim, and Deb. A special thank you to Brian K1BJ who came out to open up the building for us. Two people passed their Tech and one upgraded to General. The new General class licensee credited Bruce Prior’s (N7RR) license course for his perfect score. If you would like to take Bruce’s license course for Technician, General, or Extra, write to him at N7RR@mail.com
The next license exams in Whatcom County will be Saturday February 8 at 1000 am at the Search and Rescue building. Details under the Classes and License tab above.
All Whatcom County emergency communications volunteers are invited to attend a special meeting at the Search and Rescue building near Smith Rd and Northwest avenue (1041 W Smith Rd) on Thursday October 10th at 7pm. Deputy Director of Emergency Management for Whatcom County Kent Catlin will be speaking. This is a regular meeting of the WECG (Whatcom Emergency Communications Group), but all area hams involved in emcomm are encouraged to attend. Kent will be describing his vision for building a communications network within Whatcom County and to surrounding areas.
I finally pulled the pictures that I took at Field Day 2013 in Blaine off my SD card. Here are a few:
Budd WB7FHC drove his electric bug to FD. What a project!
Sarellite ops. They made a QSO just as the bird was falling below the horizon. Alt/Az 440/144 antenna in foreground; operating station under canopy.
Satellite Ops. Don W7AIN making the QSO and tracking Doppler shift on the VFO while Andy WA2TND positions the antenna during the pass. Gary KF7NJU looks on.
Taking a break from radio to rag chew and EAT. Everyone’s favorite FD activities.
We are already awash in RF fields from our modern conveniences, not to mention the contribution from our hobby. How about harnessing those fields for the power source and modulation medium of communications? Maybe the tin foil hat crowd are not so crazy after-all.
