You're most likely overdriving it -- if memory serves, you can't drive it with the same levels in
SSB that you can in FM because it's running class C.  Try driving it with 3 to 5W instead and see
what happens.  I run a 30W in/160W out Mirage and they suggest 10 to 15W of SSB drive.

Good luck & 73,
Joe,
