I think that the question was about where the frequency offset calibration disappeared from the calibration menu. It was there in previous versions of firmware before the UHF/VHF rework of this section. EDIT: SK2 works, I mistook it with SK1 when trying, so I misunderstood the reply.
Also, I have a question which came to me when thinking about the GPS for DM1701 about recent beta firmwares - do you limit number of writes into flash to prevent too much wear for it for settings which change quickly, such as selected channel in zone (esp. when scanning) and when updating the location from GPS (which was added in recent firmwares)?
Or is the RTC memory used for these settings with only manually entered location stored in flash (or the GPS location stored only from time to time)? Otherwise the external/internal CPU flash may start failing after some time period and write cycles (especially the quality of TYT CPUs internal flash is a big unknown, STM32 should guarantee 10,000 write cycles, I am not sure which external flash chip is used for external flash, typically it is around 100,000 cycles)
EDIT: Or are the values just stored in RAM and copied to flash only when powering off and I am worried for nothing?
