It's worth noting that the K1 continues transmitting after the tuning is 
complete, until the TUNE process is manually exited.

I'll add the obvious "or you operate far enough from the last-tuned frequency 
while using a limited-bandwidth antenna."  That happens easily if you have the 
150 kHz (typically 170 kHz) VFO span option and a dipole on 40 meters.  :-)

Re: [Elecraft] Elecraft KAT1 AUTOMATIC ANTENNA TUNER

2015-10-26 Thread Don Wilhelm

Dick,

First make certain the ATU menu parameter is set to "tun".
Then hold both the buttons in the upper right of the front panel 
together to initiate a TUNE.


If the KAT1 already has a tuning solution in place, the process will go 
quickly and you may have to listen closely to hear relays click.
When it has found a tuning solution, it will display the resulting SWR.  
Tap any button to exit the TUNE process.


Once you have Tuned the KAT1 to a particular antenna on a band, when you 
return to that band it will switch to that tuning solution.  So if you 
have done a TUNE on all bands, there is no need to re-tune unless you 
change antennas.

Have been trying to follow the KAT1 operating Instruction Assembly and
Operating Instruction manual apparently to no avail.  Obviously feel I am
missing a step somewhere.  Would be most appreciative to receive clear
step-by-step tuning instructions, re tuning, loading, SWR etc.  Thank you in
advance for your assistance in this matter.  Dick - W7MPZ
