K3LOE Mike<p>Flying to Hotlanta today for a conference. Decided not to bring a radio and to just tune around on websdr. If I have any free time, priorities will be learning about WSPR, WSJT-X &amp; Olivia and desoldering SMD IC chips. </p><p>I’m receiving WSPR signals but my tx is not being spotted.

Jesse Alexander, WB2IFS/3<p>I learned about this part of the <a href="https://mastodon.hams.social/tags/radiospectrum" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>radiospectrum</span></a> called the <a href="https://mastodon.hams.social/tags/waterhole" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>waterhole</span></a> around 1400 MHz that could serve as an <a href="https://mastodon.hams.social/tags/interstellar" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>interstellar</span></a> communications band. I was sooo excited that I took a photo of the frequency from the movie and tried to find a <a href="https://mastodon.hams.social/tags/websdr" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>websdr</span></a> with coverage in the band.<br><a href="https://www.seti.net/indepth/waterhole/waterhole.php" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">https://www.</span><span class="ellipsis">seti.net/indepth/waterhole/wat</span><span class="invisible">erhole.php</span></a></p><p>2/n</p>

Coraline Ada Ehmke<p>This afternoon I’m hanging out with WebSDR friends, exploring the radio frequency spectrum. </p><p>One of my daily go-to stations is out of Poland, Polskie Radio Jedynka broadcasting at 225 kHz. Sometimes it's talk radio, but when it's music, the music is usually _really good_ and varied. </p><p>What are some of your favorite frequencies?</p><p><a href="https://ruby.social/tags/websdr" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>websdr</span></a> <a href="https://ruby.social/tags/shortwave" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>shortwave</span></a></p>

DigitalInfinity<p>So ich muss jetzt echt mal Werbung machen für den <a href="https://digitalcourage.social/tags/amateurfunk" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>amateurfunk</span></a> <a href="https://digitalcourage.social/tags/amateurradio" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>amateurradio</span></a> !<br>Heute war der erste Abend Kurs N-Lizenz bei der VHS. Die sind so cool!

Wenn ihr technikinteressiert seid und mal in eine andere Welt schauen wollt dann schaut mal, ob's bei euch in der Nähe nicht auch nen Amateurfunkverein gibt.</p><p>So und jetzt muss ich mir nen coolen <a href="https://digitalcourage.social/tags/websdr" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>websdr</span></a> suchen und rumzappen ;)</p>
Alex (HB9IAH)<p>While browsing <a href="https://mastodon.radio/tags/SDRplay" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>SDRplay</span></a>, I was tempted to run my own <a href="https://mastodon.radio/tags/WebSDR" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>WebSDR</span></a> station using the "SDRplay nRSP-ST Receiver" 😄 <br><a href="https://www.sdrplay.com/nrspst/" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">https://www.</span><span class="">sdrplay.com/nrspst/</span><span class="invisible"></span></a></p>

Alex (HB9IAH)<p>That said, I checked a <a href="https://mastodon.radio/tags/WebSDR" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>WebSDR</span></a> after few minutes and heard <a href="https://mastodon.radio/tags/SAQ" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>SAQ</span></a> there. It was still faint in the Netherlands, probably because their antenna was way off for it, but I clearly heard it. 😁</p>
