With the new mixer, all of the IMD products are gone. I still need to match
the mixer output to the 30MHz crystal filter, but it looks like I am on the
right track.............

Has anybody ever changed the 1st mixer diodes to hot-carrier types. I have
one of these in my possession and the IMD is terrible. They've got to be
using ordinary switching diodes for the performance to be this bad. I
notice that they are using a 2N5109 post mixer amplifier, so I don't
understand why they would skimp on the mixer diodes.
