Hi
I m working on remote controlled car where I requires FM modulator & Demodulator IC. Can anybody suggest IC no's that requires less hardware or a ckt that can be used in remote controlled vehicle.
I've used NE 566 for FM modulation and NE 565 for Demodulation... and it gave up pretty good results... I guess you can have a look at it... It is widely available too... Hope that helps...
For what is worth mentioning what is the frequency range you are making the application?
I think you can pull very well suggested using a VCO chip. If you want to act as a pro, then use some reactance modulator/demodulator circuit and not relying on IC's.

What range(in meter) are you getting with your Tx and Rx? I too need it! Better idea would be to use a RF module but that would be a costly affair NE566 and NE565 is real cheap so I would like to try out your idea.
