Did I read that someone inferred that I can use a usb cable from my computer to the arduino and do some digital qso's with the KD8CEC firmware?
?
When I downloaded the ubitx_1.061.zip file and extracted. I encountered 9 ino files.?
I think this file (ubitx_20.ino) is the one that I want. but am not sure.
Do any other versions of firmware that allow digital directly. from a ubitx or bitx40?
