Ok I did end up purchasing. It. It came with the "channel mod" . Yes it is the 5 pin side mic .it has the 2166 driver with they 1969 final. (Made in the Malaysia) stamp date is 1995. So far I have had some great audio reports on Am but I still need to get it to a shop to make sure that everything is properly aligned. All seems to work great. So just wanted to say thanks to all on. The advise to purchase this radidio. Take care n 73's
