Re: [IRCA] [NRC-AM] 1610 mystery station - Invitation to #mwdx

["Jim Tonne" <tonne@xxxxxxxxxxx>]

In Oak Ridge, Tennessee, the signal on 1610 is now
(6 PM) quite clear.  Looking at the RF (at IF) on a
scope shows pretty full modulation.  Kicking in a
3 kHz mechanical filter allows one sideband at a time
to be lopped, yielding the "two-tone" pattern.  That
observation then concludes that this is a full-carrier
doublesideband signal.  Strength is similar to the
10 kW carriers on nearby frequencies but below
the level of the 50 kW signal in the low 1500s.
Some fading so it is not local to eastern TN.
