This circuit uses the same number of components as the 2-Channel circuit above but has 4 channels. The frequency of the multivibrator is determined by the value of resistance on the base of each transistor.
A 4 channel receiver has been designed by talking Electronics using a PIC12F628 micro to detect the different frequencies.

Does anyone know why most 27 mhz transmitters only have up to 4 channels?
