Thank you to all of you that have replied so far on this matter.? As I noted in my post, the replacement units as pictured by the different suppliers are identical to the module in the repeater which I believe is the one that has been in the repeater since manufacture.? It does not have an Icom logo on it, just the part number; what I believe is the production date and lot code as well as the Mitsubishi tri diamond trademark.? All sources state that the unit is new and not rebuilt which I don't think can be done based on the appearance of the module.
