[Fox_Tango] Receiver monitoring ( YO-100 )

[Michael Lawton]

Hi all,

I've been following this thread with interest. I have a YO-100 which I use
for general TX monitoring with an FT102. I'd like to monitor the received
signal as well, and the manual mentions an add-on adaptor for connecting a
455kHz IF. Does anyone know what this was, or have any details of something
I could build to do it? I assume it was some sort of 455kHz to 3812 kHz
convertor or mixer, but I can't find any details.
