Donovan,
Out of curiosity, what IF frequency are you planning to use that required
a 10.7 MHz crystal?

Does anyone know how common 10.7MHz oscillator crystals are and where I

can
get them, preferable in Canada.

The reason, I've decided to build a 21MHz xcvr and the 10.7MHz crystal,

when
multiplied by 2 is at 21.4MHz which is at the top end of that band. The
10.7MHz crystal will be running the LO (obviously).

TIA

actually, I've changed my design. I'm going to go with a direct conversion
reciever instead of building a heterodyne reciever this time around. It's a
lot simpler and smaller to build and will be a good refresher for 2-way.
(It's been about 4 years since I touched a radio.)
