The following table presents a concise description of the options available in the Channel mode.

Option

Description

TXM

Press to switch to the channel transmit frequency (appears only when using a duplex, or

TX-only channel – see Figure 2-3). After releasing the PTT, the radio returns to the receive

frequency.

BAND

Toggles between upper sideband (USB) and lower sideband (LSB).

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 function (fast/slow/off).

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.

GPS

Displays the GPS data. Refer to para. 2-9 for details.

NOTE

When ALE or CCIR is active, the following options appear:

• CALL – initiates an ALE or CCIR call.

• PAGE – displays the stacked received messages.

• MON – enables/disables the speaker during link establishment.

For a description of these options, refer to para. 2-12 (ALE mode) or

para. 2-13 (CCIR mode).
