just installed and tested FreeDV https://freedv.org/ ("Open Source Amateur Digital Voice"), and had a decent contact with someone in Houston TX using just 30 watts on 14.236MHz... sweet, a digital voice mode that is a FOSS project instead of corporate/proprietary

#AmateurRadio #DigitalRadio #FreeDV

Monitoring the FreeDV freq on 20m, when there was no signal, the app still broke squelch and attempted to interpret channel static as signal.

With upper sideband signals, this would have been a rush of white noise, a meaningless roaring hiss.

But FreeDV is built on Codec2, where the sounds of human speech...make up...the basis vectors of the encoding.

So false decodes came out like garbled phonemes, incoherent muttering.

Somebody talking. Nobody there.

@chris

I am trying to get into some #FreeDV at moment too to try up my voice contacts, but I have not noticed much on, even not many on FreeDV #QSO finder.

I.... what? #HamRadio #40m #HamRadio #FreeDV #HF

Feel like getting #freedv running on an #esp32s3 as an #opensource #openhardware #homebrew #github project?

@W1CDN I really hope that #FreeDV and #M17 modes take off as the new normal for voice coms.

Is that overly optimistic of me?

Downloaded #FreeDV last night but nobody was on. Haven't had time to try today.

Trying some FreeDV on 80m (3.736 LSB).

#introduction Hi all! I’m soon-to-be licensed ham, and I have a very keen interest in digital communications such as #dmr #packet #nxdn #dpmr #M17project #js8call #freedv and this is by no means an exhaustive list.

@dj3ei Why I'm not surprised to meet you here? :) #FreeDV ist exactly my plan for this evening. I noticed the FreeDV #HAMgroup in December, but my focus was still on getting the A license. On monday I asked Tom Kamp, DF5JL how to get access to the HAMgroup. And yesterday I've set up FreeDV and the connection to my rig. Unfortunately Rx on 80m @ home is vy bad, Tx even impossible. So I will be operating on #DL0RN with a #FD-4 antenna. At 19:00 CET I will start to set up the clubstation.

@DF2KS Hi, Sven, I'm delighted to meet you here, too!

Later today, at 19:30 CET = 18:30 UTC, the DARC HamGroup for free digital voice #FreeDV https://freedv.org/ will meet on approximately 3625 kHz, probably using mode 700E (or 700D?). I hope to be there, too, and am curious how far I'll get with my #qrp station. Details and BBB backchannel https://treff.darc.de/kalender.html . Would be great to do another long group talk!

@sm6ywy #FreeDV is cool. I need to get an extra sound card to try it in HF.
