Many thanks for the information about the backup power. Looks like you have got to know your new receiver well already!
I only know a little bit about the MR27024. So I can only answer your questions from my limited knowledge.
I don't think you can change the MW frequency steps to 10 kHz, or upload a schedule.
Yes you can manually save a frequency.
The only firmware I know of is version 1.12, I have a copy, if you want it.

Have a alternative firmware?
I found some hardware modifications, but none about firmware.
