KX3 ATU Not Tuning

Aaron K5ATG
I have a KX3 with the ATU installed. I replaced the batteries and since
then the ATU will not tune.  When I hit the ATU TUNE button it just says
25.4-1 and I can hear the relays going off. I opened it back up and looked
for any cables not connected or anything and it looked all fine to me but I
could have missed something.  It was working just fine before the battery
switch.

Re: KX3 ATU Not Tuning

From what I’ve read, you have an open circuit to the antenna.   Feedline
okay?   I had a marginal feedline and had to replace it.

I also had a bad BNC cable that deformed the connector on the side of the
KX3 and had to replace it as well.

Re: KX3 ATU Not Tuning

Low batteries can also prevent accurate ATU operation, in my experience.  The ATU will do the best it can but can’t find a good match.  Fresh batteries or a switch to external power will help.

Neither a low battery condition nor a bad feedline or connector will have
any bearing on the ATU.MD menu option.
