Nice pics.

As for the static protection diodes. Yes, I am seeing images of local
broadcasters scattered as far as 1khz from the known frequecies.
I thought it may have been my antenna. Hmmm....might rethink the
diodes. They are 1N914 as specified.

I suspose the resistor I have across the lead in to ground should
reduce static buildup.

Did I turn my tuner into a crystal radio..grin

After thinking about this a little more. What if my current impedance
mismatch between my antenna and transmission line is actually causing
reflections which are noticed by me as images on other frequencies?

Might a signal coming in on 3200 khz echo end to end back to 2300 khz?

This seems probable and the diodes may not be causing it at after all.
