[Lowfer] What type of signal am I hearing on 48.800 KHz

[Andy Bell]

Hello All: I have been playing around the past few
nights with the MultiPSK clock seeing if I can get it
to sync with the time stations in Germany ( 77.5 KHz )
, Switzerland ( 75 KHz ), and Japan ( 40 KHz ).
However, I am hearing a " unusual to me " type of
signal on some of the freq's. either some type of
RTTY, or maybe FSK. I don't know, but no mode setting
on MultiPSK will decode the signal. I can faintly hear
it at 37.500 ( Iceland ), I have heard it at times on
JJY ( 40 KHz ), the strongest one for me is on 48.800
KHz ( Puerto Rico ) always there; booming strong. If I
remember right, I think I even heard it at 73.750 KHz
pretty strong too. I am curious if anyone might know
what type of signal it is ?
Thanks for any replys: 73, Andy - KU4XR
