Hi Kenneth,

If a TTL "Can" oscillator would work, then you could use a TTL or CMOS
quad gate wired up as an oscillator with a 42 MHZ 'rock' and use that.
There are schematics on the web for building the equivalent of a can
oscillator using a 74x00 quad gate, some resistors, caps, and a crystal.

I think that 74xx00 oscillators are difficult to make with 3rd overtone
xtals (like the 42 MHz one available), I might be wrong and probably
I'll have a try.

If you need a buffer amp between the oscillator and the mixer, here is
an idea: http://www.kitsandparts.com/rfamp1.1.php


if I had space, I'd put a similar buffer after a well proven good xtal
oscillator. I have many successful designs handy, but not much space
inside this transverter :/
