[MilCom] 11.175 Wierdness (HF)

[Ted]

Has anyone else noticed the USAF ground network on 11.175 (mostly Offutt & Andrews) seems to be having some frequency stability problems? At first I thought it was my aging R71, but it seems fine on adjacent channels. Their signals seem to jump up and down between 200 Hz and 1 Khz about every 20 seconds when the big transmitters are running. Anyone else hearing it - or, is time for a new radio? Heck, probably time for a new radio anyway - several, in fact! Happy Scanning! - Ted
