9) Configuration Menu

Configuration of the modem is done through a menu system. For example, you can

select between PSK, QPSK, and QPSK reversed. You can also change the software

squelch setting, the gain of the programmable gain amplifier (PGA), turn CW

Identification on or off, turn the display backlight on or off, change the tuning

"increment", monitor battery voltage, or monitor the setting of the TX audio

potentiometer. Other items may be added to the menu at a later time.

The method of menu access is through the "Select" button on the menu and the rotary

encoder. Pressing and holding the Select button for more than ½ second will activate

the menu system. When initially activated, the display will show "Configure" on one line,

followed by "Exit" on the line below. If you wish to abort configuration, simply tap the

Select button at this time. If, on the other hand, you wish to configure one of the modem

settings, simply rotate the encoder clockwise, or counter clockwise, to cycle through the

top level menu selection. Once you see an item that you wish to change, tap the Select

button again. This will then allow you to cycle through a list of choices (again by

rotating the encoder). When the choice you wish to make appears on the display, tap

the Select button again. This will record your choice, and the menu will revert to the top

level, showing "Exit" as the default choice. You can now make additional changes, or

tap the Select button again to exit the Configuration menu.

The current menu choice is the item initially displayed when a given menu is selected.

For example, if you dial up Squelch Threshold menu item and change it to show "25",

the next time you access this menu item it will still show as "25", thus allowing you to

always see the current setting before (possibly) changing it.

Another way to see a full "status display" of current settings is to press the F12 key.

This function shows the current value for each of the changeable settings: Mode,

Squelch, CwID, Backlight and PGA. This is a convenient way to determine at a quick

glance how your modem is currently configured.

Once a change is made in Config mode, the display shows "Exit" as a prompt for you to

tap the Select button to get out of Config mode, and once you exit that change will be

effect as long as the modem has power applied. However, you have an opportunity to

save any changed Configuration settings to nonvolatile memory such that those new

settings will be in effect the next time you power up the modem. Just turn the Tune dial

one position counterclockwise and see the option for "Save Config". Tapping Select at

this point will save the current settings to EEPROM and they will be loaded and put into

effect when you next turn on the modem.

See a useful list of available menus and hot key assignments on the next page, along

with a sample usage scenario for saving data to the USB device.
