https://stream.echo6.co/videos/watch/eabb73a6-8e19-4567-9f3b-747e61bdb66a In response to a user comment about the Airspy YouLoop performance on LF & VLF, I performed a real world test on a stormy night in Europe. Plenty of submarine communications were taking place! Previous Airspy YouLoop review can be found at https://youtu.be/Qzj_IX6gh1c Please note that the YouLoop requires an HDR receiver such as the Airspy HF+ Discovery Software Defined Radio used in this video. Stations were ID'd using several websites, including https://en.wikipedia.org/wiki/Very_low_frequency https://en.wikipedia.org/wiki/List_of_VLF-transmitters https://www.sigidwiki.com/wiki/Category:VLF https://www.smeter.net/stations/vlf-stations.php and a cached page from MWList (https://webcache.googleusercontent.com/search?q=cache:uhHKke0aqMUJ:https://www.mwlist.org/vlf.php+&cd=1&hl=en&ct=clnk&gl=uk&client=firefox-b-d) I'm not overly familiar with what VLF and low LF signals should be receivable in Europe, so I'll leave it for you to comment on whether you think I was getting good performance from the YouLoop or not. I look forward to your comments 😃 Thanks for watching the Frugal Radio (FR) channel!
