switch between VFO-A and VFO-B. You may set VFO-A to the NAV band, and VFO-B
to the COM band, if you like.
MR (Memory Recall)
The MR (Memory Recall) mode of the VXA-220 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 identification of the channel. See page ?? 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 frequencies used in your area. The Book memories can be changed
by the user. See page ?? for details.
WX (Weather Channel) Memories (USAversion only)
Ten Weather Channels are pre-programmed at the factory. The VXA-220 will
automatically scan this special bank when it is selected by the user.
Reception of Weather Channel Broadcasts (USA version only)
The VXA-220 can receive VHF Weather Channel broadcasts, which may assist your flight
planning. The VXA-220 includes a ten-channel auto-search feature, which simplifies access
to Weather Channels when you are in an unfamiliar location.
To receive Weather Channels, press the [ENT(LOCK)] key (repeatedly, if necessary) to
select the Weather Channel mode. In the Weather Channel mode, “- WX -” will appear
on the display.
The VXA-220 will now scan quickly through the ten standard Weather Channels, and
will stop on the first active station found.
If there are two or more weather channels audible in your area, you may select the
alternate channel(s) by pressing the PTT switch. Pressing the PTT switch re-initiates
the scanning process.
If there are no Weather Channels in your area, the scanner will not stop. Press the
MONITOR button to stop the scanner.
You can also select Weather Channels manually by rotating the DIAL selector knob*.
To confirm the current Weather Channel frequency, press the [XFER(LOCK)] key
momentarily. The display changes to frequency indication. Press the [XFER(LOCK)]
key again to return to normal display.
To exit the Weather Channel mode, press the [ENT(LOCK)] key momentarily to return
to the VFO mode.
*1: If you change a function of DIAL and []/[] key by pressing the [F] key followed by the
[5(DIAL/)] key, you may select Weather Channels by pressing the []/[] key.
Note 1: In the event of extreme weather disturbances, such as storms and hurricanes, the
NOAA (National Oceanic and Atmospheric Administration) sends a weather alert
accompanied by a 1050 Hz tone and subsequent weather report on one of the NOAA
weather channels. You may setup the Alert function when receiving the Weather Alert
signal via Menu Item “WXAF,” if desired. See page ?? for details.
Note 2: The Weather Channel mode memorizes the last Weather Channel you have used,
and will retain this information until the radio is turned off.
Monitor Key
When listening to a very weak signal from an aircraft or ground station, you may observe
the signal disappearing periodically as the incoming signal strength becomes too weak to
override the squelch threshold setting.
To disable the squelch temporarily, press and hold the MONITOR key for 2 seconds on the
left side of the radio, just below the PTT button. The squelch will remain open and you
should have a better chance of hearing weak signals.
