I want to thank everyone who helped me figure out how to update my uBITX V5,
I practiced it on a spare Arduino Nano that I purchased... and this
morning successfully uploaded KD8CEC's V1.2 firmware to my radio.
However, this did not happen smoothly (Murphy's Law). My first few
attempts failed, but I discovered that the baud rate needed to be
57600 instead of 115200 that I was using on the spare Nano.
Thanks to all...
