[Spooks] Morse Code Broadcast

[Christmas Peter]

Yes but we aren't talkng about a spur from a dirty occilator but rather just a frequency multiple blowing out the receiver due to poor design and rfi shielding...sheer brute force of the signal and its multiple...

Since the IF frequency of most radios is 455 KHz for AM recption, that would make the received (mirror image) frequency 1630 + 455 = 2085 KHz. Some use 472 KHz and that could make the received frequency 2102 KHz.

But that doesn't mean it couldn't have been someone working a little DX, especially if propagation was good that night.  (I wasn't on the air then so don't know what conditions were like.)

I wonder if there might be a commercial station in the Maritime Service that is on the right frequency and strong enough that it would cause an RF image in your receiver on 1630 kHz.  I know that many maritime mobile and fixed stations operate in the 2.0 to 3 MHz band, for example.
