I found a Kenwood TS-830S in excellent condition and it needed only minor cleaning to get on the air with full power output on all bands.

The Kenwood TS-530SP is among some of the most popular hybrid rigs from the 80s which are still in service today. I purchased mine from N1QQV who got me into the hobby and who is now a silent key. The radio has sentimental value and operating it is like stepping back in time.
