VLF,
OK, Jay responded to me personally. We will take the challenge. The first transmission is already running: f = 8270.1000 Hz Start time: 12.FEB.2018 22:32:00 UTC (daily) Symbol period: 32 s Characters: 1 CRC bits: 24 Coding 16K21A Duration: 07:06:40 [hh:mm:ss] Antenna current: 700 mA Reports welcome :-) 73, Stefan Am 12.02.2018 15:00, schrieb DK7FC: Jay,
