What's with Key 1 and Key 2 on the QSK-5? It appears that one will work the QSK when the unit is on, the other will operate the amp normally when the unit is off. I don't see a need for both--any reason I can't simply use the one that operates when the QSK unit is on and bypass the amp when it's off? Thanks! 73 de Tom tom@k4nr.org http://www.k4nr.org
