Homebuilt NBFM Receiver
 

I'm hoping I can get some ideas and guidance here...

Here's the story so far:
I'm trying to build a Narrow Band (and/or Super Narrow Band) FM
Receiver, targetted primarily at frequencies around 75MHz (The band our
Fire service operates on here).
Now, I know the MC16136 IC would be almost perfect, and I can find many
circuit diagrams for it, as well as for the famous TDA7000 (and
children of the TDA7000), however, I can't find a reliable source in
New Zealand for these two ICs.

So what I am looking for is, a circuit diagram for a NFM receiver that
uses current production chips, that I can get my hands on. (I am
considered building a few of these, but not enough that I can order
these chips from overseas).

If anyone has any ideas, or places I can try, etc I would very much
appreciate the input.

I do have some electronic skills, and can build basic single layer
PCBs, so I'm not a total novice.

Obviously what-ever I eventually come up with, I will be posting such
circuit diagrams on the Internet, share and enjoy, etc.\

Thanks,

Nick

Farnell sells the TDA7000, you should be able to get some from them.
It's the easiest way to build a simple FM Rx.
