Ah yes, the pursuit of the proverbial "RED X", as espoused by an American quality control guru...! Don't ask me for his name, as I've forgotten it since I retired---but the ONLY sure-fire way to confirm the existence of the RED X is to be able to turn what you're attempting to "fix" either off, or on, by "activating" or "de-activating" it. So simple! Removes all of the other "noise" that could be interfering with any true root cause. ~73~ de Eddy VE3CUI - VE3XZ _______________________________________________ UR RST IS ... ... ..9 QSB QSB - hw?
