Hi Tony,toggle quoted messageShow quoted text
Your best bet is the mixer diode from an LNB
But whilst this will produce harmonics it won't tell you which one you have - unless you feed it thru a WG filter.
It should be possible to design a very broadband and easily constructed filter to enable harmonics in the region of 10 to 10.5 Ghz. 432MHz would give you a good harmonic on 10368. Measuring the distance between peaks or nulls with a rule will give you a clue as the the region of the freq.
I've just checked my old LNB's - they use a later IC in place of the old diode pair.
