Changing the Channel Steps
The synthesizer of the
FTA-850L
provides the option
of utilizing channel steps of 8.33/25 kHz per step.
The
FTA-850L
are set up with default channel steps of
25 kHz (NAV and COM bands). If you need to change
the channel step increments, select “
8.33kHz
” on the
item “
FREQUENCY STEP
” of the COMM Setup menu
in the SETUP mode.
Notes:
The 8.33 kHz steps are available in the COM Band only.
When you set the channel step to 8.33 kHz, the
channel display differs from actual operating
frequency; see the chart below. However, the
operator (pilot, tower, control, etc.) will call out the
frequency according to what the display indicates.

ANL Feature
For reduction of impulse noise, such as that produced
by an engine’s ignition system, the ANL (Automatic
Noise Limiter) feature may prove helpful.
To activate the ANL, select “
ON
” on the item “
ANL
” of
the COMM Setup menu in the SETUP mode.
