I would encourage whomever is facing issues to contact AP directly - my experience with the 75 has been satisfactory to date and I know they care a lot about their customers from the feedback I've seen [George, etc]. My 75 broadcasts 600 and 500 mixed just fine...maybe I got lucky. I sure hate to see guys going thru these issues...would be nice to think an affordable feeder could also be functional...maybe I'm just dreaming.
