Test for you then ... I'd like to build a simple FM broadcast receiver
that I can tune (and lock) to R4 for our daughter to listen to when
she's out walking the dog.

A kit would be nice but I don't want anything that scans, unless it
can be locked on a single freq (93.2 MHz?) at startup?

I think it would only need to drive a small speaker or single
headphone.

There are several ICs designed for something similar. I have, or had (Im
not sure where they are) a couple of cheap €˜Chinese radios someone gave me
which were about the size of a match box. They had a couple of buttons to
control the volume to a pair of ear phones and a couple to scan. FM only. I
think the ear phone cable doubled as the antenna. I used then while walking
before I bought an iPod.

The case was clearish plastic and, as I recall, there was only one IC and a
few support components inside- plus the batteries.

I saw similar ones on sale for a few pounds.

Considering the price/simplicity etc, the performance wasnt bad- certainly
good enough for casual listening while walking etc.

The only niggle, you had to scan through stations to find the one you
wanted, although I think I remained tuned to the last one used when turned
off and back on.

Try a google for €˜single ic fm receiver.
