Recently bought RFM. Found about five micro switches not working.
Switch Matrix - anything that says the "matrix" just scares me and makes me thing Agents are going to get me. After all these years I just don't understand "the Matrix".
Jim reminded me that it's not likely that five switches would be bad and encouraged me to check the wire connections. Thought I had but I checked them more carefully and, sure-nuff, a wire that looked well connected wasn't. A bit of solder and four out of five came right back up - I only had to change one return roll-over switch that was actually bad.
Jim always takes the time to try and shine some light when I'm stumbling in the dark.
Thanks to Jim - Again
