[Elecraft] Thoughts on internal vs external ATU for K3

[WILLIS COOKE]

You don't have to if you go back to the same frequency, but if you were on the cw band and go back to the phone band you might, depending on if the load changes.  It does not seem to remember the settings for frequencies within the band, but it is just the push of one button and two or three seconds to tune again.

Steve,

You stated " Every time you change bands, you must push the ATU Tune
button."  

If that's true then I have been operating my K2 ATU incorrectly but it seems
to work fine the way I've been doing it. Initially, or after any change, I
run thru the bands tuned to the cw portion and hit the ATU Tune button to
obtain close to a 1 to 1 swr. Once that's done I was under the impression
that the internal memory kept that setting stored and I didn't need to
re-tune (i.e. repress the ATU Tune button) until a change was made to the
system. I may go for several weeks without any changes.

So do you really need to re-tune EVERYTIME you change bands?

thanks.
chuck
