[Elecraft] WA7U-KPA100

[Todd Gahagan]

I seem to be having more than my share of problems with the amp project.
Everything checks out perfectly. Got the new firmware yesterday and it is
installed.
Everything seems to be working just as it should until I get to the Transmit
Tests portion.  Anytime I go over about 60watts the PA shuts down and I get
the High Reflected status in the K2 LCD.  It then drops to an intermittent
35 watts power output.  I have checked all coax cables, Heathkit Cantenna
dummy load, SWR bridge that I am using and can find no problems with them. I
have rechecked the SWR bridge null 3 times.  I have also closely checked T4
and surrounding components. All of T4s lead are correctly placed and
resistance checks show that the leads soldered properly.  I did use prewound
toroids.  I would appreciate any ideas.  Thanks, Todd-WA7U
