Easy DIY FM tuner on a chip wanted - ideas anyone?
Posted by Morse on July 1, 2003 at 12:58:56:
Hi everyone and thanks in advance for any help or suggestions.
I'd like to toss together a nice little FM stereo tuner to go with the rest of my DIY hifi. Okay, valves would be nice, and I've been slowly tooling up to scratchbuild a valve based superheterodyne FM tuner with stereo multiplex, BUT right now I'm looking for a quick and dirty project - something cheap and easy using *ack* IC chips. To clean up the audio a little I can toss together an audio output stage with something like 6922's or maybe some old hearing aid valves.
I see that NTE has a nice line of dedicated FM radio chips but I can't find application instructions on most of 'em and I haven't found sample schematics on ANY of them (i.e. if I buy this or that FM front end, what circuits do I have to build leading into it? will other chips like an IF amp be needed? How about a display - how would I add one? etc.).
Thanks for any help or info you can provide!
All the best,
Morse
