burned up L39 while working on a no tx power issue. when it had that surge something else has happened. The radio will not transmit. When you key the mike, the receive light stays on and very bright. When I flip the CB PA switch to PA, the receive light stays on bright. When you key the mike then, the receive light stays on but dims while keyed.
I took the mike off and tried to key the radio by touching the pins on the mike jack which I have done before. It sparked really bad at the jack and the clock and frequency counter blinked out for a second. That’s definitely not normal.
Finally the frequency counter is stuck in the same channel (26.51 approximately).
Any ideas where to check?
i checked voltage readings at the voltage regulator and they seem to be ok there and other places. So I think I toasted another component. Hope it isn’t the VCO or PLL though quick voltage checks in both are ok.
