[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.
