A mike that seems to be causing a stir in some areas. This is the Team DM5100 which is sold 6 pin so will work well with the President / Albrecht series of radios power and echo mike. I understand it can be used with no battery in some certain 6 pin radios which draw voltage from a pin but not confirmed here at the moment. For me not much known about this version and so will wait and see if can procure one for the blog. I think it will drive radios hard with audio, looks small and has the time and delay on the mike. Not seen any volume control so we will see.
