Re: LF: Weak signal on 137780.3

["Markus Vester" <markusvester@aol.com>]

The mystery signal was received between about 0:15 and 3:30 on 137780.310, with a 3.8 mHz downward shift from about 1:30 to 2:15 - somewhat reminiscent of a DFCW "GM". Greenish colour indicates southwesterly origin. The attached  screenshot was taken at 8 UT, timescale is 10 minutes per FFT.

 

I checked the other available TA grabbers around 4 UT, but no trace of the mystery signal.

 

73, and have a nice sunday,

LF,

 

there seems to be a signal on 137780.300 Hz, about 60 nV/m here.

Wondering whose it may be...

 

Best wishes,
