Default uniden pc68xl no TX


this radio has a good tr7 and tr8. i checked them. the ic1 good. and i got a radio that i use to check output on. and the radio is putting something out. i got a test radio on channel 15 just to listen for anykind of audio. the radio i'm working on is on frec. i can turn it to 14 or 16 and not hear anything on those channels. all i am hearing is just a key up with no audio. it put about a 3 on the signal meter of my test rig. tr16 has 9 volts, 4 volt and 8 volts on it on RX. It should be 9 volts , 0 volts and 6 volts and the IC2 has like 2 volts on every pin on RX. and if you put it on PA and key the mic it will stick the rf amps tr13 and tr14 on untill you turn the pa switch back to cb. if you can help i really thank you. it's been a while since i worked on anything around here. almost a year. thanks
