Hi everybody,

there IS a difference between CT9.27 (and prev) and later updates. I 
had built an interface (optocoupled) few years ago, it worked ok up 
to CT 9.27. It used only pin 1 against GND for keying. After 
switching to CT9.3*, I had save behaviour like Frank. First bip 
caused rig hang. I consulted the manual, and noticed second 
transistor for enabling (pin 17??). I added it in my circuit and since 
then: it is working well.
BTW my old interface worked fine with demo version of NA and TR.
