Split frequency operation 76
Split frequency operation allows you to transmit and receive in the same mode on two different frequencies the split frequency operation is basically performed using 2 frequencies on the main and sub readouts 76
Split lock function accidentally releasing the xfc switch while rotating the tuning dial changes the receive frequency to pre vent this use both the split lock and dial lock func tions to change the transmit frequency only the split lock function cancels the dial lock function while push ing xfc during split frequency operation 76
The dial lock s effectiveness during split frequency op eration can be selected in the set mode for both re ceive and transmit frequencies or only the receive frequency p 100 76
The following is an example of setting 21 90 mhz for receiving and 21 10 mhz for transmitting 76
To change the transmit and receive frequencies push change to exchange the main and sub readouts 76
