Re: wrong frequency after software change. #ubitx
I suspect I may have slightly misread your email post.
You have a uBITx not a BITx40?
Is your Raduino 400kHz off frequency (or did you mean 400Hz)? It does sound like it could be a similar problem to Yvon's if it is 400kHz off frequency and the LSB/USB are backwards! i.e. the EEPROM has become scrambled. However, reinstalling the stock firmware should fix that. If it doesn't the EEPROM may in fact be damaged in the Nano. It is possible there is something really wonky with your replacement Raduino: either the Nano chip (most likely) or the SI5351a chip.
