[Lowfer] 135.6 MSFSK

[Larry Molitor via Lowfer]

Maybe what I'm hearing here is not the same signal. I see a digi signal with an occupied bandwidth of about 200 Hz centered on 135.950 kHz. It is 50-60 dB above my background noise and has "sidebands" that are only 30 dB down and extend +/- 3 Khz or so. It pretty much wipes out 137.5 for me.
I have not had a chance to turn the loop to check direction, but my guess is that it is more or less west of my central WA location. I will be surprised if the origin is further south than Portland.

XND 136kHz decoded here is very  Geo stormy conditions - very odd!!

Signal on 135.6 beams up on 132degT bearing - looks like Ca - but I may be a bit skewed. Terrific qsb on this sig this morning from S5 to 0 in a matter of less than 2 secs - Overhead pulsing Au at the time - and k>7

Never heard that fast a qsb at 136kHz before -  this is a, Apple  MPEG4 recording which may or may not work on your machine....
