Tuning Methods
Throughout this manual, you will see references to sev-
eral different frequency setting methods. Each will be
particularly useful in a particular operating situation,
and they are described below:
VFO (Variable Frequency Oscillator)
The VFO is a “ tuni ng
dial” system which al-
lows you to tune through
the NAV or COM bands
using the
DIAL
selector knob, the Keypad, or the
scanner.
MR (Memory Recall)
The MR (Memory Recall)
mode of the
FTA-230
provides the user with
the ability to store and
recall as many as 150 channels in the radio’s main
memory bank. These memory channels may also be
labeled by you with an alpha/numeric name of up to
8 characters in length, to aid in quick identication
of the channel. See page 28 for details on creating
alpha/numeric labels.
BOOK (Pre-Programmed) Memories
The Book memories are
pre-programmed, either
at the factory or by your
Dealer ( depending on
your country’s requirements), typically including
the major COM and NAV band station frequen-
cies used in your area. The Book memories can be
changed by the user. See page 38 for details.
WX (Weather Channel) Memories (USA version only)
Ten Weather Channels
are pre-programmed at
the factory. The
FTA-230
will automatically scan
this special bank when it is selected by the user.
