What I meant was that 10000 KHz had an image 910 KHz below it, but a
station
that I received at 10855 KHz didn't produce an image 910 KHz below that
frequency. I was wondering why that was; why some frequencies produced
images, but others didn't. Sorry if I wasn't clear.





My first wild guess is 10855 wasn't the actual frequency of the
transmission, but it was the image of 11765. 11765 is in a standard
shortwave broadcast band. My older copy of Passport says that the BBC used
that frequency, but I don't know if they're still using it.


Here's some numbers:

Desired frequency -- 10000 kHz
Image frequency -- 9090 kHz

Desired frequency -- 11765 kHz
Image frequency -- 10855 kHz
