Transmitter Operation

"USER" Defined Digital Modes

Also provided in the FT-818 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 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
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 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 start-
ing point.
4. Finally, depending on how you wish the display to respond, you may program in a cor-
responding 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 op-
eration.
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.
