[Elecraft] Thoughts on internal vs external ATU for K3

[Richard Ferch]

You do *not* have to push the ATU button every time you change bands. 
See the firmware release notes for MCU 3.03.

The ATU remembers the last setting used on each band/antenna input; in 
fact, it remembers the setting for every 20 kHz segment (every 10 kHz 
segment on 160m, every 50 kHz segment on 10m and every 200 kHz segment 
on 6m).

If you use an external antenna switch, then you may have to push the ATU 
button every time you switch antennas on a given band.

One other thing the KAT3 gives you, by the way, is two antenna inputs, 
switchable on the radio, and remembered on a per-band basis.
