Hello Evan, sorry for delay, i checked all the informations in your post but still today I can't calibrate my uBITX;
i tried let it off for 1 day but nothing changed; i don't know how i can upload here a video of my cal process, in case i can show to you my process.
I changed Nano but is not the problem; value don't change in the uBITX Memory Manager, i don't know what do with this problem.
Thanks for support!
