London Shortwave<p>The PiZero 2W spectrum recorder runs for 7 hours on two 18650s & a step-down 5V converter (which doesn’t seem to add measurable noise on HF). And of course the batteries are hot-swappable as the unit has its own small UPS battery. The only limitation is the amount of free space on the MicroSD card 📡<a href="https://mastodon.radio/tags/PortableSDR" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>PortableSDR</span></a> <a href="https://mastodon.radio/tags/SDR" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>SDR</span></a> <a href="https://mastodon.radio/tags/HF" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>HF</span></a> <a href="https://mastodon.radio/tags/Shortwave" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Shortwave</span></a> <a href="https://mastodon.radio/tags/SpectrumCapture" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>SpectrumCapture</span></a> <a href="https://mastodon.radio/tags/SpectrumRecording" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>SpectrumRecording</span></a> <a href="https://mastodon.radio/tags/AirSpy" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>AirSpy</span></a></p>

London Shortwave<p>🇮🇳 I miss having All India Radio's English language service in abundance on shortwave!

London Shortwave<p>🇨🇺 I've been digging through my old archives and my very first spectrum recordings. Here's Radio Habana Cuba's broadcast on Fidel Castro's 89th birthday (11670kHz - 06/08/2015 0101z). I captured this indoors with a Wellbrook ALA1530-SP antenna and FunCube Dongle Pro+. <a href="https://mastodon.radio/tags/Shortwave" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Shortwave</span></a> <a href="https://mastodon.radio/tags/SDR" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>SDR</span></a> <a href="https://mastodon.radio/tags/SpectrumCapture" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>SpectrumCapture</span></a></p>
