[GreenKeys] RTTY Signal

I listened to it last nite at 0540Z and it sounded like it was marking for long periods, then sending a few characters. Since it was using 170 Hz shift, the baud rate could not be very high --- I'm guessing that it was 50 or 75 baud, based on the few characters I heard. I should have tried my WinRadio software to analyze the bit width. Another mystery station.

Hi

Are you sure it's a RTTY signal at all? Does it have a proper start  
and stop pattern? Many systems idle with a square wave of some sort.
