After my first successful FT8 QSOs with the zBitx, I switched it off.
When I later switched it on again in FT8 mode, I was surprised, that I did not have any FT8 decodes, although I could clearly hear and see the FT8 signals.
Connecting a monitor showed, that the time was off, i.e. the real time clock obviously does not work.

I opened my zBitx (very nice concept of 3D printed parts for the case!) and took a picture of the mainboard:

There is a 2 pin connector next to the RTC DS3231, which I guess is J7 from the schematics.
Most probably this should be connected to a battery, but there is none!?
Has this been an oversight during assembly and if yes, will a CMOS BIOS backup battery work?
