Elektor Magazine did a 2M FM receiver a few years ago. They have good
quality PCBs so most of the job is done. The only problem was that the
oscillator was free running and tunable. This might not be stable enough. In
this case I would suggest a crystal osc for a single frequency, multiplied
up. If you want it programmable, you will have to use a PLL circuit, and
things start to get a bit harder. Could you try E Bay for an old FM rig and
modify it?

Hello,
I'm looking to rig up a cheap way
to monitor the local repeater without having to invest in a complete
transceiver.

I've just gotten into VHF ham radio (HF is more familiar to me). I'm not

too
strong in making radio receivers, but I made VCO's, so I have some

homebrew
skills:-)
I need a 2m receiver circuit, with good selectivity and stable frequency.
I've seen some easy to build circuits with good performance on Motorola
IC's, but I can't find that circuit in my country. Well in my country

there
is a bit difficult to buy any kit or specific parts, so I will do

everything
from parts I could find at local radio shack store.

Any suggestions/help would be greatly appreciated.

Thanks,
Edgar
