The SWR bridge on my K2/KPA100 had been working perfectly for years, but I apparently blew something while making comparison measurements with a friend's K2 I was trying to fix. Now the K2 panel LCD SWR indicator reads around 5:1 for a near-perfect dummy load. Adjusting C1 makes almost no difference. I can force the SWR to read 1:1 by setting R26 toward one end of its travel and R27 toward the opposite end of its travel (instead of both at midpoint), but then every load reads as 1:1 SWR. Replacing D16 and D17 didn't help (I tried it twice). Except for the SWR reading, everything seems OK. Perhaps I should try replacing U5 and U6? Other ideas?
