[PPRAANet] RFI MYSTERY

Been awhile since in lived in CS, but 50.9 x 2 =100.8.  Seems I remember a
Pueblo station on 100.7.  Maybe they have moved to Cheyenne Mt. and are
radiating a spur in the 50.9 MHZ area (or 100.7/2 = 50.31 with 65 kHz
Deviation). Also the receiver might be experiencing some intermod with that
station.   (How about 50.31 MHZ + 690 kHz = 51 Mhz, both licensed to Pueblo. ).
Just a thought.   Someone with a spectrum analyzer might take a look.
