Can this be a malfunctioning Russian beacon or is it a known pirate/ hobbyist beacon? Previous lists have always had the letter M tagged for 7039.400 coming out of Magadan, Russia. When I was in Fiji I heard M and K at the same time due to the receiver bandwidth being so so.
This source says that M was not sounding correct yesterday
http://www.iarums-r1.org/iarums/latest.pdfOn my waterfall display this morning I could see the dashes that looked like a T but it was just too weak for audio and for carefully checking center frequency.
Right this moment I can actually hear what sounds like T but it is on 7039.350 KHz which seems far off frequency for the typical Russian beacon. Signal strength is 10 dB or so above the noise floor with periodic quick fading or interruptions in the signal. Also the time of day is wrong for receiving Russian beacons here.
