I been trying to contact the Maycom company but am having no luck. I know there somewhere in Europe anf there email always rejects my emails to them. Ity says there Email is full and rejects mine. I am thinking the part I need for a radio is obtainable through them because I see they have 2 versions of the Superstar 4900B and its the same as these superstars but with a different name and model number on the front. I needs some input on getting a hold of them. I am having a heck of a time here thanks.... Tony
