Option Description
MODE
Select the channel radio operating mode:
• SSB – single sideband
• AME – amplitude modulation equivalent
• PLT – single sideband with pilot signal.
AGC
Select the channel Automatic Gain Control mode. Micom-Z offers two AGC response
speeds: SLOW and FAST. You can also turn the AGC OFF completely.
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.
4-3.2 Configuring Radio Parameters
The radio parameters are global parameters, which are used for all the channels.
To start the radio parameters programming:
1. Enter the Radio Programming menu.
2. Press PRMT.
The PRMT option in the Radio Programming menu provides the following options (see Figure 4-1):
Option Description
BAUD
Selects the data transmission rate of the internal modem:
• 1.2 – 1200 bps
• 2.4 – 2400 bps
• 4.8 – 4800 bps
• 9.6 – 9600 bps.
DPWR
Selects the maximum transmit power for data transmission, that is, for a transmission
initiated by the data PTT. The available selections are:
• LOW – 25 W nominal
• MED – 60 W nominal
• HIGH – 100 W nominal
• MAX – 125 W nominal.
The transmit power used in the other modes is independently selected for each channel.
If the selected data transmit power exceeds the transmit power configured on the
operating channel, the radio will use the lower channel transmit power.
When operating the radio without the optional cooling tray, it is recommended to use the
lower power settings (LOW or MED).
MST
Enables/disables the sidetone heard in the speaker when you transmit using the
microphone.
AST
Enables/disables the heard in the speaker sidetone when you transmit using an
accessory connected through the rear panel.
