[GreenKeys] 50 baud RTTY

I'm hearing a station signing 9MR and giving some other call signs as 
well such as "MRB", "MCB", "MGO" and "RMMJ" as well as "JULL" on 
8463.872 Mc using 50 baud and. 850 cycle shift with a mark freq of 
around 1425 cycles.  The mark freq is more than likely not actually 1425 
but that's where i tune the radio to get the best copy thru the filters 
as using the high end stuff of 2125-2975 really restricts the high freq 
tones.  I also copy some of their RYRYRY's.  It sounds like they have a 
lot of chirp, perhaps a sour osc tube.  Signal is chirpy but about as 
copiable as the German DDR station on 10 mc when i have a good signal 
from over there.

Just something else to copy.  Using MMTTY as it's easy to change the 
baud rate, shift and stop bit settings.  Changing the stop bit from 1 to 
1.5 didn't seem to make much difference.

As i copy more this just seems to be a signal to occupy a frequency with 
no real traffic.  Doubt i'll be able to copy long enough to verify that 
is what it actually is for.
