Out at my workplace we have difficult to repair and somewhat unreliable European transmitters!Just got done fixing one of them!One problem after another-Meanwhile the GE's 40 yrs old,CEMCO,60 yrs old--still work.-and easier to fix.Wouldn't you know it-the fellow that works out here that loves these Euro-transmitters is on leave!Wish he was here-would save it for him.He likes the Engineering-to me too complicated,breaks easily-too complex control system-its less reliable than the equipment its controlling.Auto tuning on these transmitters can no longer be trusted.So--tune them by hand like the older ones.
