The M30 Series Wireless Transmitter is a crystal controlled low-power FM Transmitter with a self-contained antenna. It is available in 3 models:
- M30 – uses a replaceable 9 volt alkaline battery.
- M30R – has a self-contained 9 volt Ni-Cad battery and comes with separate, plug-in charger.
- M30FB – same as the M30 except it is equipped with a spring-loaded “push-to-talk” switch.
The M30 Series Wireless Transmitter transmits on a single frequency in the 30 MHz to 50 MHz range. The operating frequency is printed on a label on the bottom of the transmitter case and must match the frequency of its companion receiver which may be a model R31, R31AC, FM731 or FM831.
