Overview of free tune
The transceiver can be used as a free-tune receiver. This enables you to tune to any
frequency within the transceiver’s operating range of 250 kHz to 30 MHz. In some
circumstances, the options installed on your transceiver may enable you to transmit
while free tuning, for example, the Amateur Mode option enables you to transmit
during free tune when tuned to amateur band frequencies.
