oscillator needed

[el_squid_2000@yahoo.com]

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.

Any suggestions for simple circuitry ?

** Own an FM broadcast radio of any kind?

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?
