Just wondered if anybody has experience of using the K2/100 in conjunction with a Collins 30L-1. I'm hoping the KPA100 switching line (rated at 200v) will cope happily with the antenna change-over relay of the Collins, which I think sits at about 120v (but I'm not sure of its current rating). A true mix of the modern, with the not so modern! -- 7K2, peter g3xjs
