Hi. I just bought the radio 2 weeks ago. Just got the time to try it out. The radio transmits and receives fine. It did not come with a mic. So i found the wiring diagram to wire up my d104. White pin-2 shield and blue pin-1 red pin-3 I hope that is right. Any way i tried two different d104 mics. I have carrier but no modulation? Any ideal of what mite be wrong.
