I might be able to pick up a Kenwood TS940 in a trade, and the 940 looks like a great older radio. I have heard a couple of people mention that the TS930 is one of the best CW contesting rigs ever build, so I figure the 940 should be good at CW as well. Are there any typical problems that show up in the 940 that I should look for or be aware of? 73 John AF5CC
