finally I found the problem...it was my BFO off...(11.053 i think, as factory); i set new value (reference with 1000 Hz USB with the RWM time station at 9.996 KHz carrier) and now rx is perfect and sa

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 her

thanks for the info; it's seems nothing changed also with your method; i tried with another nano (programmed etc) but the mast cal value is lost...anyone has CEC 1.200 and ubitx v5 and has the same pr

Thanks gary, yes i'ved tried to push ptt longer but nothing changed...yes i see "calibration set! Etc" message...on power on everything is lost...maybe a e2prom defect in the arduino?

Can you explain? I tried with once push of the encoder but nothing changed

I will try but i think i've tried also with encoder press; i follow this step: setup on , set calibration, zero beating with reference station like RWM, press PTT, setup off. On power on value is lost

Yes i use ubitx manager but , if my master calibration value is 18 how i can add this value in the cal value in the software? 18 correspond to? Thank you Mark

Same problem here, same software. Ubitx v5 with nextion 3.5, any suggests? Can't save master cal value, Thank you
