Everything has gone fine with my new KAT100 until I got to the SWR bridge 
null adjustment.  The best null I can get is about 1.9 to 2.0 volts. I 
checked T1 and even took it out and rewound it with new wire. The 4 leads of 
T1 are in the correct holes and continuity checks fine. Everything else in 
the bridge circuit looks fine to me and the coax jumpers I'm using are fine. 
I have the KPA100 so I'm attempting the adjustment at 20 watts.  U5 is 
installed correctly.

Very frustrating!  Any help is GREATLY appreciated!!
