One of my SCIIs has stopped working. IT will occasionally throw the first switch of the six assigned to it. Other five, no indication of command received. Almost all of my TMCC problems over the years have involved engines, and I believe that all their problems have been solved by modifying or replacing the antenna. I know the SCII receives command from the base via the radiated track signal like an engine. Has anyone else experienced reception problems with SCIIs? What solutions have you found and is there anything internal which can be repaired, replaced, or modified to improve signal reception?
