I finally got a chance to replace the FS1000A modules on my Tx board today with the XD-FST versions that I just received. Unfortunately after just 5 - 10mins the Tx LED on the Rx board stopped flashing every 5 - 10 seconds and would only flash every minute or so.
I checked the soldering and did continuity tests on the pins of the FS1000A module before re-installing outside and all looked good. The Tx unit is still flashing the Tx LED every 5 seconds or so, so it looks like the Tx unit is working as it should.
I am now wondering whether I should replace the Rx module on the Rx unit and see if that makes a difference.
A guy at work suggested I also try a radio on the AM band, off station, to see if I can hear if the Tx unit is actually transmitting when it shows it is. I'll let you know how I get on with both this exercise and the replacement of the Rx module.
Another thing I have just noticed when I removed the power from the Rx unit, although it is still being powered by the PC USB cable, is that the TX LED has started flashing every 5 seconds again. Is there anything that would cause it to stop receiving the data correctly when it is being powered by the 12V power supply?
