Option Description
BAND
Toggles between upper sideband (USB) and lower sideband (LSB). The sideband change
takes places only after the current call is ended.
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.
•
••
• CLIP
Toggles the clipper on/off.
•
••
• NB
Toggles the noise blanker on/off.
•
••
• ATTN
Toggles the attenuator on/off.
PWR Selects the transmit power level: LOW – 5W; MED – 10W; HIGH – 15W; MAX – 25W.
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).
BW
Selects the filter bandwidth.
• 2.1 – 300 to 2100 Hz
• 2.7 – 300 to 2700 Hz
• 3.0 – 300 to 3000 Hz
• 3.3 – 300 to 3300 Hz. Always select this bandwidths 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.
FREQ
Displays the current frequency.
3-12.3.2.2 Replacing the Current Channel While in the Link State
If during an individual call you find that the channel in use is not good enough, you can replace it with
a better channel.
NOTES
• Channel replacement is possible only during an individual call in
the ALE mode.
• Only the initiator of a call can replace the channel in use.
