Synteza SI5351 wg UT5QBC

[SP5OXJ]

Yuriy, you are probably right. I guess I've some "painters" - only which ones?
Works soft for f100cbt6b (only ver. from 2017) and f100c8t6b. others don't work at all or don't save menu changes.
I'll leave the 2017 soft because the PCB may not withstand the next CPU change.

Thank you for your help,
73! de Jacek.
