Alrighty, I'm back with some updates. The straight-wire counterpoise=20 worked well. Well enough to not warrant any other changes. It's in its=20 final place and working fine. However, I did first lower the UART comms baud rate, which should've=20 lowered the over-the-air transmission bit rate, but I didn't really see=20 any improvement with that. I do need to keep a good wireless transmission link in my arsenal, so I=20 will investigate LoRa. Much thanks for the help! Cheers, -Neil.
