Quoting the manual for my VI Plus (3-5.14)(QSK FAST/SLOW) "QSK can be overridden entirely by plugging a hand or foot operated transmit/receive switch into the rear panel MUTE jack." Question to Scott: How hard would it be to accomplish the same on the Orion, using perhaps the rear panel SPARE jack as the input. Best Regards in 04 Mike W7MGC
