Subject: Re: Topband: 1940 kHz Intruder
I’m fairly confident that I’ve identified the signal to be coming from 1660
kHz, WWRU in Jersey City NJ. There is considerable fading but I confirmed the
source by listening to the programming, switching back and forth between two
VFOs on the TS890.
I’m located in Eastern Long Island, NY about 50 miles east of NYC. The 1660
signal is well over S9 and the 1940 is S4-5 max. At times, the signal changes
abruptly in amplitude.
