In some cases, it might be intriguing to build a single channel FM
BCB receiver. Build it like a ham band converter, with plenty of
tuned circuits at the fronte end, little or no RF amplification,
and a good mixer. Being fixed tuned, one could optimize it for
that frequency, and not worry about tracking, or the problems of
ganging a number of tuned circuits. For the local oscillator, one
could go with a crystal oscillator chain.

Going to www.KitsAndParts.com by Dieter Gentzow, W8DIZ,
you can find the old Motorola MC3362P (2 for $4) which is a
complete FM receiver IC. There's a full Motorola datasheet there
with application data. A one-IC FM receiver for headphones.

For some audio power output, he has National LM380s at 4 for $5.
For an RF preamp, he has Fairchild J310 J-FETs at 12 for $4.
There's also a respectable number of Micrometals toroid cores for
IF and RF filtering. Datasheets for all except a full info range on
the Micrometals cores (which some think are made by Amidon).
www.micrometals.com for full core information.

If the MC3362 is too much or too little, Dieter has 612 Gilbert cell
ICs for mixer-oscillator applications and MC1349 gain blocks (its a
slightly higher gain version of MC1350) for the IF.

A fairly good supplier of oldies but goodies in semiconductors and
toroid cores.
