The NE602 is a favorite with the Ham crowd. Plenty of projects found on
the
web, including FM.

Hi

It could be that the ICs I'm searching under are not popular with
homebrewers. Or, that articles are in printed publications, (like Practical
Wireless etc) or folks just rely on application notes.

ICs I've mentioned are ones typically found in your average AM/FM radio
perhaps in the '90's.

LA1177: Electronic Tuning-Use FM Front End for CarRadio, Home Stereos.
LA1266: AM/FM Tuner Syatem of Electronic Tuning Type.
LM7000: Direct PLL Frequency Synthesiser for Elexctronic Tuning.

LA1235:FM IF Sysyem Applications.

But, I think if anyone wants to mess with these ICs it's more economical to
get some 90's radio, take it apart and rebuild it, with mods. That a way you
get all the hard-to-get bits, like the display.

So, these could be the reasons I've not found many articles incorporating
the ICs I mentioned.

Although I have been interested an amateur radio for about 30 years,
I've
never focused much attention on radios made with ICs.

Lately I have got an interest in FM receivers, and have discovered some
FM-related IC's/chipsets. ICs such as LA1177, LA1266, LM7000, (these
three
being a chipset), and LA1235 etc etc.

But, doing a web search , you cannot find any homebrew AM/FM RX using
these
IC's.

Why is this? I would have though they would be ideal for the hobbyist
to
mess around with.
