Hans, one FYI on updating from 015 to 016 firmware ...
When going from 015 to 016 I did not see a factory reset, and so didn't have to reset any configuration parameters (such as VFO frequency separator, comma or dot and others). It just worked and kept my settings (which I liked).
It may be intentional, but it made me wonder if someone going from a pre-015 firmware to 016 will get the necessary Factory Reset invoked for them. I suspect your firmware update process has logic to determine when the factory reset is required. But thought I'd point this out ... just in case it needs your attention.
