Re: QMX real RTC #qmx

Hi Pawel, it would be nice and useful to be able to have a watch independent of the QLG2 GPS and be able to manage it directly as we like directly from the QMX to always have the time at hand during QSOs, but the frequency calibration always remains which without GPS can happen, for those who use the qmx in wspr it would be mandatory / essential to have it.? 73 iu8eun

Hello OGs, YLs,
Question, actually it could be a feature request.. The stm32 chip has an internal real time clock. Wouldn't it be nice to make usable? Currently the clock may be shown on the display ant it starts counting - starting from zero on power-on. Two things would be needed:
?- software - a settigs menu where the user would be able to set current time without a need of playing with gps
?- hardware... the diagram shows that cpu's vbat leg is connected right to the gnd... adding small battery there would be required to persist the time on power off. And since stm32's rtc draws some microAmps, some small button battery should suffice.
What do you think?
