====== Model 1320 Sidetone Thump Fix ====== **From the Ten-Tec Reflector August 12, 2003** Just fyi, the thumping noise in my sidetone is fixed, I found that when I used a dummy load, the sidetone was just fine, on the antenna it thumped, so I removed the output coils L8, L9 and L10, and rewound them as tight as possible, reinstalled, and problem completely went away!
