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. Willis 'Cookie' Cooke K5EWJ

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 -- View this message in context: http://n2.nabble.com/Thoughts-on-internal-vs-external-ATU-for-K3-tp4627735p4628261.html Sent from the [K3] mailing list archive at Nabble.com. ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
