I am not completely understanding the tuning performed using the KX3 with the 
KXPA100.

First, I’m not even completely sure which mode I should be in: Byp, Man, or 
Auto. I have three antennas - one is a vertical which is resonant on 40 - 10 
except for 17 and 12 m. I have an OCF that is resonant on 40 - 10 *including* 
17 and 12 m. I also have a shortened 80 m inverted vee that I have to tune if I 
go to 75 m.

Currently, I have the shortened 80 m antenna selected with my antenna switch. 
No matter which mode I use, I never hear any relays in the KXPA100 ATU and I 
never get below about 7.4:1 SWR. The KX3’s ATU works just fine with the same 
antenna. Pressing the ATU TUNE button on the KX3 starts the 25 LED blinking but 
stopping the tuning does not stop the 25 LED from blinking. It’s blinking right 
now and I’m not tuning anything.

I’m going to go back and verify all my cabling (I also have a PX3 in the mix) 
and make sure I haven’t cabled something wrong. Otherwise, what else can I look 
for?

Thanks,
