We have a bunch of SS-32's (the predecessor of the SS-64)and we key the CTCSS on ond off by simply switching the supply voltage into the board. This works well for eliminating the ID tones on links as well as EchoLink repeaters. We just let the xmit tone follow the rcv tone. Click on the link below for a diagram of the simple transistor switch we use. The pin numbers are for Motorola backplanes, but the idea should work for GE as well. http://webpages.charter.net/k4hal/Com-spec-sw.gif
