Re: [IRCA] 1500 Mystery Station



This noise appears in both the upper sideband and lower sideband of 1500,
meaning it's not likely this is being generated from a station above or
below 1500.  From careful frequency measurements tonight under the Perseus
microscope, the mystery station's offset appears to be 1500.007 kHz - maybe
useful to those with calibrated SDRs who are chasing it down.

73,
Tim
