Frequency Mode
Frequency mode is used to receive and transmit on a specific frequency. You can
select the frequency type, change the frequency being used, and operate a variety of
functions and options to facilitate good transmission and reception. You can also
store the frequency in a channel of your choice.
There are four frequency types:
■
SMPX (Simplex Frequency) – the same frequency is used for transmission and
reception. The frequency can not be zero.
■
DPLX (Duplex Frequency) – transmits on one frequency and receives on a
different frequency. The frequencies can not be zero.
■
RXO (Receiving Only Frequency) – defines a frequency for reception only.
■
TXO (Transmitting Only Frequency) – defines a frequency for transmission only.
The available frequency ranges are:
Reception
