QDX: Weird Problem


John N0TA
 

I am repairing a QDX -- One of the final BS170's (Q10) was blown. It appears to be working now, with the exception of the RED LED. When in TX, it slowly fades ON/OFF, at about 1 second intervals (rather than the 3 quick flashes). PTT seems to be correct - it flashes ON/OFF at one second intervals. It seems to transmit normally, and I've made several contacts. The receiver works great.

I have RESET the firmware, as well as updated to 1.08a. What else do I need to be looking at? Should I replace the other BS170's?

Thanks, John, N0Ts
