NOTE: Be care-full, when you press the microphone button, you can transmit 5 watts.
As a final test, with channel 20 setup on the FM92E connect your signal generator to 53.000 MHz. You should
hear a signal through the FM92E with approximately 100 mVolt of signal.
NOTE: If the VCO will not tune properly or the transmitter side will not come within voltage range, then check
that pin 19 of the VCO module is 0 Volts on receive and 10 Volts on transmit.
