Just picked up a mint condition uniden washington with the 8719 PLL. It has amazing recive but the modulation could be better. Every now and then it looses modulation completly and I think it's in the stock hand mic, I hope anyway. You can unkey, wiggle the cord and then it will come back. I have a 4 pin tuner +3 and was wondering what the wiring diagram would be to hook it up.
