“USER” Defined Digital Modes

Also provided in the

are two convenient “USER” Digital modes, one each providing USB- and LSB-side injection, which may be used for SSTV, Fax, Pactor, and other digital operating modes.

Here is an example involving the configuration of the USER mode for RTTY with USBside injection (as opposed to LSB injection, used in the default “RTTY” mode):

1. Use Menu #26 to set the Digital mode to “

USER-U

.”

2. Press the / will appear on the display).

key, as needed, to select the DIG mode (the “ DIG ” icon

3. Now use Menu #27 to configure the transceiver’s passband response. Once in the Menu mode, rotate the knob to select Menu #27 (

DIG SHIFT

), and rotate the knob to set the desired BFO offset (depending on how your TNC’s tones are set up). For typical high-frequency tone use, a setting of about “

+2100

” will be a good starting point.

4. Finally, depending on how you wish the display to respond, you may program in a corresponding display shift, using Menu #24 ( DIG DISP ). Remember to press and hold in the key for one second when exiting the Menu mode.

5. The setup of the AFSK drive level is identical to that described previously for RTTY operation.

The USER-L and USER-U Digital modes should allow you to operate on any

SSB-based AFSK Digital mode. Note that the “PSK31” configurations will also work well for many Digital operating situations.
