K3

[Mike K5NU]

I have been unable to run the 50w tx gain calibration after installing my KPA3.  I opened it back up and found two unsoldered diodes on the KPA3 board.  However, after resoldering the two diodes, unfortunately still not able to run the calibration.  Getting ERR TXG on some bands and HI CURR on others.  Hair pulling time.

This is due to the FLTX setting not being set to the correct value I believe. Take a look in the construction manual and the owners manual for the correct configuration and setup parameters.

I hope this helps,
