I called Justin lastnight about it. He said that a common problem was people blowing out the proccessor in the radios. I figured it out before talkinto him. I looked at a schematic and noticed pin 6 on mic socket was a 13.8 volt and I could not imagine how many people would have messed them proccessors up by wiring mics wrong or saying gee Ill plug my RCI Mic in considering its the same 6 pin set up. Well NOT!!!!

Its almost done Im looking forward to getting it back there waiting on a few small parts but the cpu is in 
they have none of these radios in stock but in fall will have some available they are the same radio but have the original manufactuers name on them which is Maycam but as I said there the exact radio. Anyone interested in these units let me mknow and I can check on availability and pricing or atleast get a ballpark figure. Im thinkin if we get enough people that want them I can get a better deal on a quanity order. They say there good radios but the biggest problem is people trying to plug rci 2950 mics in because it looks to be the same well they find out fast that its not when the cpu blows out. The reason for this is theres a 13.8 volt pin on one of those mic pins and well you can just imagine the rest. Anyways I ll be sitting eagerly to receive the radio my like that radio alot so it will be his.
