DIGI MODES OPERATION
Most modern DIGI Modes should be run
with the radio set to DIGI MODES.

up DIGI Modes is beyond the scope of
this manual. In general The only
adjustment is the TX audio gain which
is adjustable in
Software Menu item
#20 (Gain TX DIGI).
RTTY OPERATION
RTTY is normally run in USB mode
which enables it to take advantage of
the radio’s narrow filters. When
running typical 170 Hz shift, you can
use a bandwidth of 500 Hz (normal) or
250 Hz on a very crowded band. You
must use filter F4 for this and adjust it
manually. See example 3 on page 14.
AM/FM MODE OPERATION

must first enable AM/FM Mode in the
Software Menu item #16

FM Mode as described in SINGLE

Compressor in FM Mode.
