Let others learn from my mistakes. I built a new EX/RX version 2. When I tested it, it would work OK but only for about 150 feet and any obstacle would get in its way. Had this been my first EX/RX I would have said, OK wireless works but not very good. But I had built other EX/RX and knew I could reach anywhere on my property. I knew I could transmit from the front yard, thru my house and still receive it anywhere in my back yard. So I knew something was wrong. After much rework and careful inspection I found, when I built it, I had put the jumpers on for both unit 2 and unit 3 (for storage). Removed the jumpers and it worked anywhere perfectly.
Point being, had I not known wireless worked better than that, I may have just thought it was not very good. People having distance problems, check your jumpers and for bridges on those pins.
