Arnie the DXman | HF4<p>Oh well, so today at 0900z &amp; 1200z, the historic <a href="https://mastodon.radio/tags/Alexanderson" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Alexanderson</span></a> alternator will make a transmission again, on 17.2 kHz CW 🗼</p><p>Haven't been testing antennas too much, but so far, my 15x4.5m loop, aimed roughly NE/SW (while <a href="https://mastodon.radio/tags/Grimeton" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Grimeton</span></a> is to NNW), seems to do pretty well.

G7IZU RRD<p>Space Weather</p><p>Solar Flare Alert:</p><p>An M3.2 flare peaked at 13h10 UT 08 Feb causing a minor R1 radio blackout across the mid-Atlantic. </p><p>The flare came from AR3576, which is continuing to be very active. </p><p>I've fired up my VLF station signal strength plotter (Spectrum Lab and a long-wire antenna plugged direct to the soundcard input*) and recorded the effect of the flare on some of the signals. The biggest dip can be seen on station GBZ (19.6 kHz) located at Anthorn, Cumbria, approx 500km north of my location.
