We have 2 repeaters that are more or less the same. One is on 2 meters and the other is on 440. They both exhibit the same problem, they lockup after a while and then need to be power cycled. They ran for years without issue.
We have the Instruction manual for the Zentron controller, but nothing on the radios. The 440 radios are Motorola M44GM29C3AA's back to back. That's the only model number on the radios. Does anyone have any information on them? A Google search shows 2 Chinese sites having them for sale on e-bay, that's it. Seems strange. Any information would be greatly appriciated, Joe Loucka -- AG4QC
