Futuristic Robert [KJ5ELX] :donor:<p><a href="https://infosec.exchange/tags/VLF" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>VLF</span></a>/#LF/#MF spectrum waterfall recorded for 5 hours overnight with <a href="https://infosec.exchange/tags/lightning" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>lightning</span></a> in the area. Unfortunately the time is incorrect but I started this around midnight, a few hours later a storm system came through. Used an <a href="https://infosec.exchange/tags/RTL" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>RTL</span></a>-SDR and a modified MLA-30 active loop antenna in the attic. </p><p>The solid line around 0.060 (60 kHz) is <a href="https://infosec.exchange/tags/WWVH" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>WWVH</span></a>. All the stuff on the right pat 0.50 (500 kHz) is the AM broadcast band. </p><p>There's harmonic/image of <a href="https://infosec.exchange/tags/WWV" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>WWV</span></a> in there somewhere, probably due to a cheap setup but worth more experimentation to clean up, particularly needs better AM broadcast filtering (it's not supposed to show up). The signal path is <ActiveLoop>--<Power Injector>--<AM Band Filter>--<Upconverter - Ham It Up Nano>--<RTL-SDRv3> </p><p><a href="https://infosec.exchange/tags/GQRX" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>GQRX</span></a> <a href="https://infosec.exchange/tags/SDR" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>SDR</span></a></p>

developer<p>Before the interwebs, we used to check <a href="https://mastodon.sdf.org/tags/wwv" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>WWV</span></a> for solar conditions, now commonly referred to as "space weather".</p><p>Geophysical alerts are broadcast from WWV at 18 minutes after the hour and from WWVH at 45 minutes after the hour.</p><p>I truly believe that without WWV and <a href="https://mastodon.sdf.org/tags/wwvb" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>WWVB</span></a>, life would lose much of its luster, </p><p>HAPPY BIRTHDAY WWV! </p><p><a href="https://mastodon.sdf.org/tags/dx" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>dx</span></a> <a href="https://mastodon.sdf.org/tags/swl" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>swl</span></a> <a href="https://mastodon.sdf.org/tags/ham" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>ham</span></a> <a href="https://mastodon.sdf.org/tags/wwvb" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>wwvb</span></a> <a href="https://mastodon.sdf.org/tags/spaceweather" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>spaceweather</span></a></p>
