To check my loop is working I run SM6LKM's VLF receiver to see levels of the Alphas and GBZ etc and notice a station sending 5 number sequences in CW around 17.975kHz. This frequency was not accurately measured as I only caught about 2-3 minutes before the signal disappeared. It has now reappeared with what sounds like high speed CW. Can anyone tell me who this might be? Signal was about 30dB over noise on my loop aiming roughly WSW-ENE. I wasn't aware any of the military VLF users still used CW. 73s Roger G3XBM -- http://g3xbm-qrp.blogspot.com/ http://www.g3xbm.co.uk http://www.youtube.com/user/g3xbm https://sites.google.com/site/sub9khz/ G3XBM GQRP 1678 ISWL G11088 |
