Or the subject line could be why good house cleaning is a must. On Saturday I posted a message concerning my KAT100-2 not achieving a good SWR. I had the bottom off all weekend, reflowing solder, re-calibrating the SWR bridge. Pulling my head out. Two kind souls responded to my post, but neither offered the correct solution path. Even The Gary didn't point me to the correct path. Man last night I was depressed. And then I found it. I'm not an electronics guy, but I can play "Wayne Says" pretty good. Where I was building the stuff was on a birds eye maple table that normally hosts the Drake C-Line. I removed the C-Line and put a canvas cover over it to protect the table. When tinning toroids cr*p falls down. A miniscule piece, perhaps a 1/16 x 1/8 somehow got on the top of the board and was shorting C22. (Sorry don't know the metric for the VE/rest of the world.) Pull out the pick and remove it and the KAT100 was dead on. And I was looking on the bottom of the board not the top. It wasn't until I brought out the DVM and magnifiying glass to look at resistances across the toroids from the top that I discovered it. My confession will most likely cause my old pal WD9DHI to give me grief at the Cedarburg fest, well so be it. But if it helps one other person to avoid my angst it would be worth it. Bottom line - check both sides of the board. And stay clean. 73, Joe N9JR _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
