Duane, Have run into the same thing as others have mentioned. Should you need to replace the two diodes in question, you may want to consider mounting them on the opposite side of the board. I found they were easier to replace, should you have to do it again.
The best thing to eliminate this problem is to disconnect the antenna when the radio is not in use. Some go as far as disconnecting any power or computer lines as well. A good antenna switch, like the Alpha Deltas or separate surge suppressors with other antenna switches will help. The same devices could be used on both antenna positions on the KAT100 too. Too, any power sources (power supply, logging computer connected to the mains) should also have surge suppression to help protect "back door" hits. I'm partial to Tripp-Lite products. Hope you've found the problem and have it fixed.
