href="https://infosec.space/tags/RadioSpectrum" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>RadioSpectrum</span></a> and that we should be more mindful of, espechally since the solution to overcrowded <a href="https://infosec.space/tags/spectrum" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>spectrum</span></a> is rather obnoxious as in <em>"dialing up power consumption to implement ever more complex coding schemes"</em>...</p><ul><li>Not to mention it's easier to secure an optical link and I think that it would be best if said

href="https://infosec.space/tags/UVOL" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>UVOL</span></a>"</em>, cuz <em>"VOL"</em> and <em>"UVLOL"</em> or "<em>ULOL"</em> may be too much of a bad take) could really do wounders.</li></ul><p>Even if it can only do like 12Mbit/s for USB 2.0 it'll still be practical for many use-cases.</p><ul><li>As you said: You want to focus on

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" target="_blank">#<span>radiospectrum</span></a> called the <a href="https://mastodon.hams.social/tags/waterhole" class="mention hashtag" rel="nofollow noopener" 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" 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" 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" 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>
