Phil's Cobra 148 GTL(Taiwan 1978)...
The radio had many issues when it came into the shop...horrible tx audio, truck stop mods galore..the radio was receiving on one channel and transmitting on another. The unlocked clarifier mod was all kinds of wrong...
I put the clarifier mod back to stock and replaced several parts that were removed or clipped out of the circuit...

New S-meter and ultra bright white led
