Cobra 142 gtl Transmit problem.

A well reputed cb technician said it still needed some work. I checked TP7 and TP8 and the driver is drawing current, but the final is not. hmmm.... Do you imagine the 1.5 watts I was dk was from the driver only, and as I spoke(modulated) the final would sink the signal instead of amplify it, causing my watts to drop? :blink: The final is good, as I have checked it. Adjusting the bias has no effect either. I imagine its somewhere in the final circuit, or bias circuit, that is causing it not to work. Without the right equipment this is VERY difficult:confused1:

    Hello gentlemen and Ladies. I have the dreaded RCI-2990 receive issue where my radio gets distorted when people get close to my location. I found the C90 Capacitor, but I can not for the life of me find the C89 capacitor. Can or does anyone have a picture of the exact location of C89 ? Thank you in advance, Wes
