It's quite common to hear intermod from broadcast stations on 
multiples of 10 kHz. This CAN occur within the transmitter of one of 
the stations, but also within some non-linear detector near you (or 
not so near you) that then re-radiates it on attached conductors. In 
Chicago, I was regularly bothered by spurs like this that came and 
went at random times not related to station sign-on and sign-off or 
power/pattern changes. 

Here in Santa Cruz, I hear a very weak product on 1810. In Chicago, 
they were often strong enough to copy the audio. There are also 
occasional problems with intermod from poorly operated shortwave 
sites.
