40 FT-817ND Operating Manual
“USER” Defined Digital Modes
Also provided in the FT-817ND are two convenient “USER” Digital modes, one each pro-
viding 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 USB-
side 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 / key, as needed, to select the DIG mode (the “DIG” icon
will appear on the display).
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.
