Hi - I need a 10.7 Mhz signal to debug an FM receiver kit I am putting
together. I have a Z8 Encore microcontroller eval board I bought
sometime ago so I might be able to use the pwm signal from it, but
otherwise I'll probably need to use some sort of crystal oscillator.
Any suggestions for simple circuitry ?
Thanks in advance,

** No you dont.
You maybe need an FM modulated signal at 10.7MHz.

Just tap into the IF strip and you have your signal.
Look for 10.7 MHz ceramic filters or small IF transformers .

If it is a wideband receiver, you can get by with modest stability. A
simple Hartley or Colpitts oscillator would work fine. A crystal oscillator
will provide better stability, if needed.
Any chance you can borrow a signal generator?
