If you're up for a test, try the two .hex files attached. One for an encoder, and one for a
decoder.
Both files have been compiled for a 12F635. Schematics for connections are in the screen
captures. If your RF modules can handle 4800bps, connect the baud pins to Vcc.
For 2400bps connect the baud pins to ground.
D0-D3 on the decoder are momentary, and should stay high for as long as a button on the
encoder is held at Vcc. Let me know what kind of range you get.
