Keep in mind that for most operators the "TUNE" operation happens only once on each frequency segment within a band. Once L/C and antenna port values are stored, you'll hear a brief 'click' from the KAT500 and it's ready to go.
If you really want to avoid being surprised by a tune operation commencing when you go to a new frequency, step through the bands at the intervals listed in the manual (or at least do this on your favorite bands/frequencies) to "teach" the KAT500 what the proper L/C/Ant settings are for each frequency. Then it will almost instantly return there next time you transmit. 73 Ron AC7AC -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of [email protected] Sent: Sunday, January 27, 2013 3:53 PM To: [email protected]; [email protected] Subject: Re: [Elecraft] [KAT500] Auto Tuning Does anyone know when the new firmware will become available which will eliminate the need to "Tap the XMIT button on the K3" after the KAT500 finds a match? It would be nice if we only had to hit the ATU TUNE button once on the K3 and the entire tuning process would be automatic. Mike AC6JA In a message dated 1/27/2013 2:47:18 P.M.

Set the KAT500 output port by tapping the ANT button. 4. If you are using a KPA500 put it in standby. 5. Hold the XMIT button on the K3 to activate the K3 tune power. 6. The KAT500 will start tuning. You don't have to push the TUNE button on the KAT500. 7. When the KAT500 finishes tuning Tap the XMIT button on the K3. 8. If you are using a KPA500, put it in operate mode. 9. Start having fun! 73, Tom Amateur Radio Operator N5GE ARRL Lifetime Member QCWA Lifetime Member On Sun, 27 Jan 2013 16:23:32 -0600, Randy Moore <[email protected]> wrote: >I am trying to help a friend understand auto tuning on his KAT500. >Bear in mind that I have not yet touched a KAT500, so I haven't been >able to play with it to sort this out.
