If you have a K3 with the internal automatic antenna tuner installed
(KAT3), you can assign text labels to each of the two antenna jacks
(ANT1 and ANT2). Once you've assigned a label, tapping the ANT switch
or changing bands will briefly flash the antenna name. This serves as a
reminder of which antenna is in use -- especially useful for those of
in the 50 And Beyond club.
For example, if you have a triband yagi and a dipole connected to the
K3, you might name them "YAGI" and "DIPL".
One good reason to assign names to the antennas: you may want to A/B
test antennas on individual received signals. The ATU covers a wide
matching range, allowing you to use each of the two antennas on bands
outside their design frequency range. So, you could end up with several
bands on which both antennas are useful. This is especially true during
field outings, where you might have two long-wire antennas oriented in
different directions.
Here's how to assign names:
1. Select ANT1 or 2 by tapping the ANT switch.
2. *Hold* the ANT switch until the antenna symbol and blank text field
appears on the VFO B display.
3. Use VFO A to select which character to change.
4. Use VFO B to select a character (A-Z, 0-9, and various symbols).
5. After selecting all characters, tap ANT to return to normal
operation.
This is covered in the Owner's Manual under Basic Operation/Antenna
Selection and Matching (page 22 of the rev C manual).
