What are the practical differences between the RM and RM2 remote controls for the SM series of transmitters?

0

The RM2 does not have an LCD readout and can not set the frequency of operation of the SM transmitter. The RM2 uses a potentiometer for the gain control setting of the SM where the RM has the LCD readout. This means that you can only set the gain to an approximate value where as on the RM it can be set exactly. The speaker on the RM2 is not quite as loud as on the RM so the maximum range is a few inches less. The lithium battery on the RM2 is inserted into a clip on the circuit board and requires removing the back cover to replace, though it should last for years.
