I Have a Realistic Navaho TRC-458, PLL: D858 AND PCB: PC196BD, It will turn on and light up, but no tx, When the mic is keyed, something is heard clicking in the radio but no tx meter movement. I have tried changing the RF final and the driver, any suggestions?

Try replacing transistor TR24, this is a common fault.
