[HCDX] Re: [SWL] Question... RTTY on 11.690

[Mikhail Timofeyev <timofeyev@xxxxx>]

I have also noted unusually strong RTTY signals in the 6, 7, 9 and 11 
MHz mostly during local evenings (1400-2100 UTC) last some weeks. It 
seems all these signals are from one location somewhere in/near 
Eastern Europe. The exact frequencies vary almost daily. Here are 
some observations:
Sep 05 1500-1700  9584 11864
Sep 05 1700-	  6008, 7188, 9584, 11864
Sep 11 1800-1910+ 6164 (also 9867)
One more RTTY is very often on 6103 with short transmissions (5-10 
minutes each).
Maybe utility lovers will be able to help us?

There were also some other strange utility jamming-like signals in 
the official broadcasting bands last time (digital?), for example, 
one of these ones was this evening (Sep 11, 1800-1900 UTC) 
approximately on 7237-7238...
