The following table presents a concise description of the options available in the Frequency mode.
Option Description
T/R
Selects the transmit and receive frequencies and frequency type.
BAND
Toggles between upper sideband (USB) and lower sideband (LSB).
SQ
Toggles the squelch on/off. Always select OFF for CW operation.
DSP
Accesses the Digital Signal Processing menu, which includes the following options:
• CLAR
Enables to control the clarifier (off/lower frequency/higher frequency). The
function key is not available for TXO (transmit only) channels.
• NF
Enables to control the notch filter (off/lower frequency/higher frequency).
The function key is not available for TXO (transmit only) channels, and in
the CCIR mode.
• CLIP
Toggles the clipper on/off.
• CC
Toggles the ClearCom function on/off.
• ATTN
Toggles the attenuator on/off.
PWR Selects the transmit power level: LOW – 25W; MED – 60W; HIGH – 100W; MAX – 125W.
MODE
Selects the operation mode:
• SSB – single sideband
• AME – amplitude modulation equivalent
• PLT – single sideband with pilot signal.
AGC
Controls the automatic gain control (fast/slow/off).
BW
Selects the filter bandwidth.
• HS – high sensitivity filter (450 to 1500 Hz) for best voice communication under
marginal conditions
• 2.7 – 300 to 2700 Hz
• 3.0 – 300 to 3000 Hz
• 3.3 – 300 to 3300 Hz. Always select this bandwidth for data transmission
• LSM – bandwidth optimized for use with low speed modems (1450 to 1950 Hz)
• CW (Continuous Wave or Morse operation). The bandwidth used in this case is
selected by MENU > PROG > RAD > PRMT > CW.
RCLV Displays the receive level. The RCLV item appears only if the received signal level display
is not permanently enabled using MENU > PROG > RAD > PRMT > RCLV.
STOR
Stores the frequency parameters in the selected channel.

Move the cursor backwards and forwards. When these function keys are used in
conjunction with the UP/DOWN scroll keys, the frequency scrolls according to the location
of the cursor, enabling you to change the frequency with greater ease.
GPS
Displays the GPS data. Refer to para. 2-9 for details.
2-7.2 Selecting Operating Frequency in the FREQ Mode
NOTE
You cannot use the FREQ mode if the radio is locked. To unlock, refer
to para. 2-10.
To enter the Frequency mode:
1. Press MENU to display the Menu screen.
2. Press FREQ. The last used frequency blinks, and the frequency type is displayed in the top line.
