I used to own the first version of the Insignia NS-HD01. It was and still is one of the best radios for DX, but quite the opposite if near an FM transmitter.What Radio are you using?
I live like Half a Mile from 2 transmitters
There's like FM overload on emply channels on All my small radios
When NY's 94.7 was WFME, you could hear Harold Campings voice along with WSOU or WFMU drowning out several stations across the dial, within 5 miles of the transmitter. The newer version is way better with no overload.
