    Does anyone still sell AM receiver chips? I'm interested in putting a radio together, but the old school crystal radio just doesn't work for me. I've tried several variants, but I just don't think there are any stations strong enough around me.

    I have found a few RF amps that go before the crystal, but at the point I'm going to have a pretty large circuit. So I figured I'd just as well use an IC to simplify the whole thing- but I can't seem to find any for sell.

    The last simple one I remember was the ZN414 (from memory)

    That is the main one I've seen listed in some old schematics, but I can't find it. I think its been discontinued for a few years or something. I was hoping someone here was into old radios and might know of a specialty site that dealt in this sort of stuff.

    If all else fails I could try the RF amp, but I don't have all of the specified resistors or caps in my collection, so that would mean buying even more stuff without knowing if it would work.

    Hi Kyjosh,

    the AN7224 is a FM and AM IF chip, as are the LA1260 and LA1266

    the datasheets are available on line, I can send them if you cant find them
    these chips are often found in car radios and portable radios

    cheers
    Dave
