Hello Mac,
Usual is correct, but the 1940 kHz intermod is not a usual case.
The intermod on 1940 kHz is being heard hundreds of miles away, far from
very strong signals that might cause 1940 kHz intermod in nearby the receivers.

Isn't this sort of thing usually an occasion of fundamental
overload of the receiver front end? Attenuation is probably
the only remedy.
ICE made a high pass filter at one time as a possible aid.

So that’s where it comes from! That spur is S9, I live about 5 miles from
those towers. So has anyone contacted the two stations? Is this something
the FCC could be involved in? FYI I’m two air miles from WABC and luckily
they don’t give me any problems. My Flex radio is tight as a crabs butt!

Hi Rick
I've attached a photo of the four 237 foot towers used by 1660 kHz WWRU
and the four 237 foot towers used by the 1380 kHz WKDM.
The two directive antenna arrays share the same site at
350 Paterson Plank Rd, East Rutherford NJ

The 1940 kHz intruder is the third order intermod of 1380 and 1660 kHz
