[Elecraft] K3

[k5nu]

Can someone assist?   All went well with K3 until the very last calibration.  After KPA3 install, the tx gain cal will not run above 12 w setting.  50w tx gain cal will not run and gives ERR TXG message.  Tx gain cal will run correctly at 12w or below.  KPA3 module problem??  Before I uninstall the KPA3, perhaps someone has an idea of something I am missing?  I have checked all the other settings and all seem to be where they should be.
