I'm building a KPA100 and am having trouble with the SWR bridge adjustment.
I'm getting high swr on the lower bands and can't get 1:1 on even the upper
bands.
160 9.9:1
80 9.9:1
40 9.9:1
30 9.5:1
20 6.7:1
17 5.0:1
15 4.5:1
12 4.0:2
10 3.7:1
(I know 9.9 is the highest it will show and it's probably higher on some)
I've checked T4 and it seems to be working properly. The toroid was build
by the
toroid guy. The diodes all seem to be in the proper orientation and
working.
Can anyone point me in the next step in figuring this one out?
Thanks
