Last night is the first time that I've heard it so wide. If I hear it again, I'll save a screenshot with the P3 Utility.
Jim N7US -----Original Message----- It's been there, 24/7 it seems, since we first got 30m. I think it's one of the primary users we are supposed to avoid QRM to. 850 Hz shift, decodes just fine in MixW and MMTTY to continuous random characters which would be characteristic of most of the not-so-new TTY encryption devices. It's pretty strong daytime here on the western frontier. It's at most, about 2 KHz wide, which would be about right for 850 Hz shift RTTY. I haven't heard anything else around it, but I'll listen around 0400Z tonight. 73, Fred K6DGW - Northern California Contest Club - CU in the 2011 Cal QSO Party 1-2 Oct 2011 - www.cqp.org On 9/19/2011 10:00 PM, Bob Cunnings wrote: > I've been hearing (and seeing on the P3) an 850 Hz shift RTTY signal > on 10.130 MHz for years now, virtually every evening.
