As I like the challenge to identify new beacons, I started monitoring it. It became a kind of a nightmare, trying to to catch the beacons callsign. It seems to be very chatty, transmitting a whole bunch of unuseful text. despite the fact I got a lot of good quality fragments via aircraft scatter, it took me hours to identify it as F1ZBK. At least I am pretty sure it is, as there is a second callsign in the end of the text: F1DND, maybe it\u00b4s the keepers call.<br><br>The text decoded so far is:<br>&#8212;&#8212; beacon f1zbk jn38bp nancy \u2026 854 khz \u2026 5 watt \u2026 f1dnd \u2026 orange KA \u2026 &#8212;&#8212;-<br>Where the &#8220;&#8230;&#8221; represent gaps and KA is the prosign for &#8220;Attention&#8221; or &#8220;New Message&#8221; (not to be used at the end of a message, like AR).<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">There are many beacons running in bad modes like reversed F2A or keying the subcarrier of F2A, but transmitting such a lot of stuff is worse.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It would be a great advantage, if all beacon keepers will respect the<a href=\"https:\/\/iaru-r1-c5-beacons.org\/index.php\/beacon-requirements\/\"> beacon requirements<\/a> as published in the <a href=\"https:\/\/www.iaru-r1.org\/index.php\/downloads\/func-startdown\/1008\/\">VHF Handbook of IARU R1<\/a>.<br><\/p>\n","protected":false},"excerpt":{"rendered":"<p>June 7th, 2019 When looking for EA2TZ\/B during a beacon check a couple of days ago, I mentioned a signal with strong doppler shift about a khz below.
