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.
