[Elecraft] Thoughts on internal vs external ATU for K3

[Steve Ellington]

The K3 tuner does store it's settings in memory but you must transmit in 
order to get the tuner to change to your frequency. Let's say you're on 80m, 
all tuned up and hop to 40 meters. If you don't transmit and your reception 
may be rather weak because the tuner is peaked for 80 meters. I usually hit 
the ATU tune button and let the tuner switch to it's memory settings. I do 
this instead of hitting the key and transmitting a full 100 watts. Maybe not 
necessary but seems like it might be easier on the finals.
So yes....you need to transmit somehow to make the ATU change. It doesn't 
follow along as you spin the dial like ICOMs do.
