Since you have the KAT500 inline and have your K3 internal ATU bypassed, you should never need to press the ATU TUNE button.
To send reduced power to the KAT500 for its tuning, press the TUNE button on the K3. If you take the time to 'train' your KAT500 by allowing it to store tuning settings up and down each band, you never have to worry about it again. Ideally, you program the KAT500 to switch antennas automatically and not have to worry about manually switching. Not so of course if you use multiple antennas for the same band. Since you only connect from one antenna port on the K3 to the KAT500, I'm not sure how the K3 ANT button would switch to different antennas on the KAT500. To me it's actually easier to change antennas using the KAT500 ANT button. These are all just my experiences. 73, Mitch NWØM -- View this message in context: http://elecraft.365791.n2.nabble.com/ATU-Tune-with-the-KAT500-tp7628038p7628040.html Sent from the Elecraft 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:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected]
