Do you see those numbers on the display? Cool, isn’t it? That means I’m smart. Very smart. Bright and clever too. I admit I’m not too good looking, but I do have something of a genius in me. Come on guys, give me a round of applause. I did it! Finally fixed my Kenwood TS-440S. I feel like a million…..whatever currency is worth something nowadays. So, how did this sharp and brainy fellow do it? Simple: follow the 8 Volts.
After I rebuild VFO#5 last week I measured 8 Volts where I should measure 5. This bugged me for a week: where did those 8 Volts come from? So on Sunday morning I fed the family, kissed them good-bye and locked the door of my shack. With schematics, PCB layout and a DVM in hand I started out on my journey following the 8 Volts. It was a difficult track with many resistors on its path, a conductor or two and inductors to counter them. And then I arrived at a three-way junction called FET. Junction FET is known for regulating those obstinate Volts. But what do you know? Junction FET was tired beyond repair and those 8 Volts were going all three ways, where they clearly shouldn’t be. Now those of you who have travelled similar paths before (or should I just call you “old geezers”) know that you should handle junction FET with care. But until now I got away with rough-handling them. Not this time, so I quickly made amends and put in another junction with loads of TLC and some solder. And my journey ended there and then.
My thanks goes out to my family, the Yahoo TS-440S group, Mr. Liu for the components and to you, my dear readers, for putting up with me. SEE YOU ON AIR!!!
P.S. Your turn. I think I deserve at least 10 comments telling me how great I am, don’t you think?
