TS-830 repair started

Comments Off

[Today’s run: 4 miles]

I’ve been looking at the old bank balance and also at a stack of radio stuff that I have which I am not using.  It finally dawned on me that I have some stuff I could either use or sell if only I would dive in and make a few repairs.

The Kenwood TS-830 is a 1980’s vintage HF transceiver.  It has the reputation for  having a very sensitive receiver.  I bought mine off of ebay a few years ago.  It worked just fine for awhile.  It started to get very flakey so I put it under the desk.

I investigated  (google is my friend!).  The problem usually is the bandswitch.  They used little rivets to hold the switch contacts into place, touching circuit board traces.  And the little rivets get loose over time and make just intermittent contact with the board traces.  The solution is to take the RF board out, take the bandswitch sub-boards out, and solder the contacts to the traces.  There are 7 sub-boards and each has 12 switch positions.

I’ve got the board out.  I need to buy some solder wick so I can get the sub-boards out neatly.

Thanks to http://www.qsl.net/af4o/bandswitch.htm for helping me get the right info to get started.
