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.
For a Micom with the internal vocoder option, this position displays PVT, DGTL, or CLR.
Pressing F1 then toggles the operating mode of the vocoder.
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.
•
••
• NB
Toggles the noise blanker function 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 (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 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.
< − −
< − −< − −
< − −
and
− − >
− − >− − >
− − >
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. 3-9 for details.
NOTES
• The RCLV item appears only if the received signal level display is not
permanently enabled using MENU>PROG>RAD>PRMT> RCLV.
• The GPS item appears only if your radio includes the GPS option.
