RTTY on 5346.48 kHz: what mode is it?
 
Greetings:

All last night and through the present time I am copying FSK RTTY (around
45 - 50 baud?) on 5346.48 kHz; signal was 20/S9 last night and about
S2 now. I am unable to hear it on web-controlled receivers in NC
and Ham Lake, MN (I am about 140 mi. north of the latter). I was unable
to decode the modulation (using MultiPSK) in any RTTY mode, normal
or inverted. The shift is about 850 Hz.

Can anyone else hear this signal? Can you decode it?

Regards,

Michael

I'm not hearing it here on the East Coast, but that may be because
conditions have been pretty poor here the last couple of days.

At 5345 kHz (center) I have fsk, 850 shift, 75 baud,
s9 in socal now at 1:50 utc. It's there all the time.
There are many others like it.
I googled this:

I believe it is applicable.

I was using a fairly wide filter and was on the upper side of
the signal; it is actually at 5344 kHz USB to put mark/space
at around 500/1350 kHz. Signal 20/S9 at 0440 GMT in No. MN.

Thanks for that link; a good read and impetus to record and
analyze this signal.

Michael
