Re: fm wireless microphone

what is with that fm transmitter?
if you want to make a good fm transmitter (stereo ) use BH1417 or BA1404

I have the same problem

I have another question about FM transmitter. If FM is used for guitar or microfone, is better to use high frequency (300Mhz, 800Mhz) with modulation. This is necessary to eliminate FM noice and influence from power supply and other.

And I want to ask, Is there in the net some schemes with high frequensy transmitter and reciever?
Thanks
