Hi Alan,
Thanks for sharing.? Our club is in the midst or integrating a FlexRadio 6600 into our station for remote operation.? Like you, we're going to use a RPi to control relay, including remote on/off.
I chose to use FTDI USB relays vs GPIO relays, but only because of the convenience of using a USB cable to a centrally located relay board/box.? The trade-off is that things are rather serial? - using crelay - but it works flawlessly.??
So, now I'm pondering, is USB likely to be more resilient to "short duration" drops in the GPIO?
Tks es 73,
