John VK7JB,
I have TWO QDXs that both suffered the same fate as yours -- working perfectly, then mid-transmission death resulting in high current on receive (400 mA) and a hot IC2.? I removed the four BS170s but the high current remains.? IC5 may be the problem, or perhaps Q6 (the T/R switch).? But nothing other than IC2 seems hot.
Have you solved your problem and/or do you or others have suggestions for me?
Thanks so much and 73,
Kirk
