I am trying to wire this mic to a Ar-3500.I was using this mic on my Yaesu ft 1200,i just got a ar-3500 that has a 8 pin..All I see is 1-5 is basically for the scanning purposes.Think only 3 pins are used 6.7.8. transmit,shield,audio.I have no paper work on the shure mic...as for the shield its most of the time with blue,but what I am seeing its just calls for shield.I have blue,white,black,red,shield..its adapter with a hand key..i have almost tried every way on this.i am just wondering if the hand key is the problem...Thanks Any Info would be appreciated..thanks..rick
