[Elecraft] KAT3 Auto Tuner issue

[Don Wilhelm]

Mike,

If you can select Bypass or Auto in the configuration menu, then the 
presence of the KAT3 is known to the K3 firmware.  What level of 
firmware are you using?  Perhaps you should upgrade it if it is backlevel.

Holding ATU should change between Bypass and Auto (just like the 
configuration menu).  Tapping ANT should change between ANT1 and ANT2.  
Tapping ATU TUNE should begin tuning.

Which of these button functions are working and which are not.  If you 
can be more specific, then perhaps someone with a KAT3 can respond and 
you can compare notes.  I do not have the KAT3 installed here.

73,
