A trip to Old Buckenham to see Tony Walters about some work on the transponder. There is a bit of a story to tell about the KT76 with a KT76A faceplate but for now suffice to say it seems to be responding with a low power output. Tony is very pleasant but I sense not too keen to get involved with replacing the transponder as he knows the work invoved. I too, now know that the KT76A requires a different tray and a different plug with everso slightly different pins to those on the Bendix King KT76.
