I would like to transmit digital audio via radio. I have the radio side sorted out ok. I have a transciever that is capable of 9600 data via the discriminator (RX) and direct drive (TX).
My guess is to use something like the MC3418 to encode the audio into a digital signal that can be feed into my transmitter.
I do not know where to find such a chip in canada. Maybe another delta modulator exists or a better (still inexpensive) way of doing it.
Maybe I should buy a $20 GE cordless phone and see what I can remove from the device.
Any one doing something like this? Any ideas?
