K3 TX Gain Calibration Failure-Resolution

[w0mu]

I replaced the LPA board and my K3 now passes the Low and High Power TX
Gain Calibration tests.

We believe that there was a failure of one of the drivers which required
much more gain to get the desired 5 watts out of the board.

If your K3 has the transverter board and it passes the 1mw test then
everything before the LPA board "should" be functioning properly.  
There is only a couple of parts between the transverter stage and the LPA.

The radio was putting out 50 watts so we believed that the 100 watt unit
was also working fine.

As always the support from Elecraft was excellent.  Gary and Rene were
great and Rene tested the new LPA board in a K3 prior to shipping and
made sure it got out the door.  This is my main K3  that is heading to
J6.  Gary felt that we would be taking a big risk taking the rig with it
failing the TX Gain tests.  If that board had failed completely the
radio would have been useless.

Thanks again to all the Elecraft gang!
