The positions of antennas and arrangements of anything inside the house near the receiver, or in the back yard between the receiver and TX0, has not changed. Some part had to have failed.
It makes no sense why a system would work practically flawlessly for months to suddenly stop working? There are no other 433.92MHZ devices of any significant strength being received so I can't see what is happening being caused by another transmitter nearby.
TX1 is on the roof about 15ft directly above the receiver. Absolutely no issue with TX1 or the sensors connected to it.
TX0 is the original transmit board I've had and have been using since I first started this. It is in the back yard about 100ft or so away.
I just measured the battery voltage with my multimeter and it is 13.01VDC fluctuating to 13.00VDC on transmit. 13.00VDC at the terminals on TX0.
