DG1JAN :mastodon:Wow, the digital HF Mode RADE V1 can pack a speech signal with an audio bandwidth of 8kHz, into 1500Hz of RF bandwidth working down to a SNRs as low as -2dB. <a href="https://radiosocial.de/tags/freeDV" class="mention hashtag" rel="nofollow noopener" target="_blank">#freeDV</a> <a href="https://www.youtube.com/watch?v=7OfrYwtiKgw" rel="nofollow noopener" translate="no" target="_blank">https://www.youtube.com/watch?v=7OfrYwtiKgw</a>

Muro deGrizeco<a href="https://mastodon.hams.social/@Geojoek" class="u-url mention" rel="nofollow noopener" target="_blank">@Geojoek</a> On an only partially related note, I was goofing around with <a href="https://toad.social/tags/FreeDV" class="mention hashtag" rel="nofollow noopener" target="_blank">#FreeDV</a> mode a few years back.USB headset for human, USB dongle for radio. Rolled up speech got changed to Codec2 beeps and boops, transmitted, decoded and played elsewhere.Best part is, with squelch down, codec interprets incoming radio static as random human phonemes!Pigs grunting, inarticulate gurgles, blurted half words, weird muttering came out the speaker!I got to try that mode again.<a href="https://toad.social/tags/HamRadio" class="mention hashtag" rel="nofollow noopener" target="_blank">#HamRadio</a>

PE1PUXPlaying around with FreeDATA (<a href="https://freedata.app/" rel="nofollow noopener" translate="no" target="_blank">https://freedata.app/</a>) app on 40 meters. What a nice modern application, can operate keyboard-to-keyboard QSO's and leave messages from a remote PC using a webbrowser. Seems like a nice modern alternative to <a href="https://mastodon.radio/tags/JS8CALL" class="mention hashtag" rel="nofollow noopener" target="_blank">#JS8CALL</a>. It's based on the open source <a href="https://mastodon.radio/tags/Codec2" class="mention hashtag" rel="nofollow noopener" target="_blank">#Codec2</a> which is also used for <a href="https://mastodon.radio/tags/FreeDV" class="mention hashtag" rel="nofollow noopener" target="_blank">#FreeDV</a> and <a href="https://mastodon.radio/tags/M17" class="mention hashtag" rel="nofollow noopener" target="_blank">#M17</a>. No need for proprietary software modems like <a href="https://mastodon.radio/tags/VARA" class="mention hashtag" rel="nofollow noopener" target="_blank">#VARA</a> anymore. If you like stuff like <a href="https://mastodon.radio/tags/VarAC" class="mention hashtag" rel="nofollow noopener" target="_blank">#VarAC</a> or <a href="https://mastodon.radio/tags/JS8" class="mention hashtag" rel="nofollow noopener" target="_blank">#JS8</a> give this a try! <a href="https://mastodon.radio/tags/hamradio" class="mention hashtag" rel="nofollow noopener" target="_blank">#hamradio</a> <a href="https://mastodon.radio/tags/ham" class="mention hashtag" rel="nofollow noopener" target="_blank">#ham</a> <a href="https://mastodon.radio/tags/freedata" class="mention hashtag" rel="nofollow noopener" target="_blank">#freedata</a>

Christian HB9HOXToday at <a href="https://mastodon.radio/tags/HamRadio2024" class="mention hashtag" rel="nofollow noopener" target="_blank">#HamRadio2024</a>, I got the change to pitch a dream of mine to several radio vendors. I just did a write up [on my blog](<a href="https://hb9hox.radio/en/posts/radios-for-sofware-tinkerers/" rel="nofollow noopener" translate="no" target="_blank">https://hb9hox.radio/en/posts/radios-for-sofware-tinkerers/</a>).In short, I would love to buy ready-to-use radios I can extend in functionality though software. This would make experiments with new things like <a href="https://mastodon.radio/tags/m17" class="mention hashtag" rel="nofollow noopener" target="_blank">#m17</a>, <a href="https://mastodon.radio/tags/freedv" class="mention hashtag" rel="nofollow noopener" target="_blank">#freedv</a> and the like easier and more accessible.Let me know if you would like to have such radios. And if you do, please talk to vendors as well.<a href="https://mastodon.radio/tags/hamradio" class="mention hashtag" rel="nofollow noopener" target="_blank">#hamradio</a> <a href="https://mastodon.radio/tags/experiment" class="mention hashtag" rel="nofollow noopener" target="_blank">#experiment</a> <a href="https://mastodon.radio/tags/tinker" class="mention hashtag" rel="nofollow noopener" target="_blank">#tinker</a> <a href="https://mastodon.radio/tags/learn" class="mention hashtag" rel="nofollow noopener" target="_blank">#learn</a> <a href="https://mastodon.radio/tags/sdr" class="mention hashtag" rel="nofollow noopener" target="_blank">#sdr</a>

Jeff Sonsteinjust installed and tested FreeDV <a href="https://freedv.org/" rel="nofollow noopener" target="_blank">https://freedv.org/</a> ("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<a href="https://masto.deoan.org/tags/AmateurRadio" class="mention hashtag" rel="nofollow noopener" target="_blank">#AmateurRadio</a> <a href="https://masto.deoan.org/tags/DigitalRadio" class="mention hashtag" rel="nofollow noopener" target="_blank">#DigitalRadio</a> <a href="https://masto.deoan.org/tags/FreeDV" class="mention hashtag" rel="nofollow noopener" target="_blank">#FreeDV</a>

Muro deGrizecoMonitoring 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.<a href="https://toad.social/tags/FreeDV" class="mention hashtag" rel="nofollow noopener" target="_blank">#FreeDV</a> <a href="https://toad.social/tags/AI" class="mention hashtag" rel="nofollow noopener" target="_blank">#AI</a> <a href="https://toad.social/tags/hamradio" class="mention hashtag" rel="nofollow noopener" target="_blank">#hamradio</a>
