Looking forward to the notes. Yes it could be fairly simple if what ref 0 wants is a string that essentially says the system is fixed with 3 d accuracy. Perhaps after that the ref 0 makes no checks other then the string keeps coming with the correct quality. Not to push a particular proc but any of the low end ones will do that stunt very easily. That would be pretty sweet. Paul WB8TSL
