Eric, I'm usually dyslexic on Yundas! It's a MSR2000. About 12 years ago I converted a base station variant to a repeater. As I recall I had some difficulty configuring it; i.e. there were some jumpers to add and remove, but thus puppy has been trucking along at a very busy site and nary a problem, 5 mHz split on VHF. Because it has been working so well I was wondering if some the older mega-kg Motos were produced with equal filtering in all variants. I was just luck, I guess.
