2-7. USING THE FREQUENCY MODE
The Frequency mode enables you to select freely the receive and transmit frequencies. You can select
the operating frequency type, change the frequency being used, and operate a variety of functions and
options to assist transmission and reception. You can also store the frequency in a channel of your
choice.
There are four types of operating frequencies:
• SMPX (Simplex Frequency): the same frequency is used for both transmission and reception.
• DPLX (Duplex Frequency): the radio transmits on one frequency and receives on a different
frequency.
• RXO (Receive Only Frequency): defines a frequency for reception only. You cannot transmit
on a frequency configured as RXO.
• TXO (Transmit Only Frequency): defines a frequency for transmission only. You will not
receive on a frequency configured as TXO.
The supported frequency ranges are:
• Reception: 100 kHz to 30 MHz.
• Transmission: 1.6 to 30 MHz.
NOTE
The ALE, CCIR, and Frequency modes are mutually exclusive.
2-7.1 Frequency Mode Options
In the Frequency mode, you can operate a variety of functions and options which can eliminate noise
or otherwise assist reception and/or transmission.
The structure of the FREQ menu is shown in Figure 2-3.
