Haven't disconnected the PA but will try as soon as it gets a little warmer. It is putting out full power though. I don't think it made any difference pluging the mic in. This is with just the built in controller. Yep, pretty sure with all but the 10v card it stays keyed. All the cards work in my other station so they seem to be OK. Can you think of anything outside of the cards that would keep it keyed? Thanks, Ben > Does it do it with the PA output connected directly to a dummy load?
