Lee is correct, I have had numerous times signals every 10KHZ across 160
all the way to 80 meters, the loudest being on 1810KHZ at times.
The culprit turned out to be a station on 1540KHZ. the second harmonic
3080
was mixing with a station on 1270khz, ended up 3080-1270 = 1810KHZ.

Hi we just got QRV on 160 right before the SP and noticed AM BCI at 1800 kHz
and every 9 kHZ up from there. Since 9 kHz is the BC channel spacing here I
suspect two adjacent stations are mixing. Somehow somewhere. Maybe here in my
station, one of the BC stations or somewhere else?
Greetings Bob, Having BC intermod on 160 meters has been a problem for a many
years.
It generally occurs from 2 or more of your 9KHz spaced BC signals mixing
together and coming out on their spacings on 160 Meters.
Mixing is the key word here and will be the key if you find the source.
