I had one and was quite disappointed by its image response (even in
the absence of strong signal IMD, overloading, etc.). For example,
WWV on 10 Mhz was equally strong on 9545 kHz. I never saw the
schematic so I know nothing about its front end and evidently
it is single conversion but one would have hoped for a varactor
tuned preselector

How is image rejection on yours?


Its acceptable for emergency, but not what I'd want for daily use.
I have a 50 KW FM transmitter and multiple cell sites within a mile
Right now I'm restoring a 1950's era national NC183R with a properly
designed front end, with two tuned RF preamp stages.

I also have a HP 312B frequency selective voltmeter:
