You have two frequencies, solve for the third.
1940 = 2 * x - 1610 = 1775 (out of band)
or 1940 = 2 * 1610 - x = 1280
I would start looking at the allocations for a community
where you have a 1610 and 280 close together (preferably
co-located).

Hi All

I heard a frequency 1610khz said.
No directional antenna to the south east. Just North and NE nothing
heard on those. It is heard on the inverted V at varying levels.
The info draws a picture. See link below.

Hi Jim,
No one has yet reported a strong enough signal to be sure if its a mixing
product or a harmonic. Because everyone -- so far -- is reporting a weak
signal I suspect its a mixing product. Two reporters said that the audio
is badly distorted and appears to carrying two programs.
The signal it too weak here for me to analyze.
It appears to radiate from the vicinity on northern NJ, NY City or
southern NY
Perhaps a Topbander is that vicinity will report a stronger signal

I'm much too far away to hear anything, but the obvious question is, "is
it a harmonic or a mix?" So is anyone hearing it loud enough to tell if
there are two programs or only one?
