[Elecraft] KX3 2 mtr ATU problem

[ejkkjh at gmail.com]

I installed the KX3 2 meter module about a week ago, it all seemed to go ok.
The module seems to work fine but now the ATU in the KX3 will not tune up on 80 or 160.
Best SWR KX3 shows is  about 10-1 on freqs I have used many times before where ATU used to get near 1.1. 
I used same cables, antenna, with different tuner and HF rig, two different antennas, tune up fine as before.
Any help or ideas would be appreciate.  73  and Thanks
