Possible memory upgrade for the GD-77?
Posted: Tue Mar 23, 2021 3:13 pm
Brand new to the GD-77 and starting to learn it. So please bear with the potential noob questions....
Where is the DMR ID's/contacts stored? I'm assuming they are stored in the 1 MB Winbond flash chip. Correct?
If so, could the Winbond chip be replaced with, lets say, an 8MB chip and allow for far more ID's to be stored (entire contact database).
I know this would require several steps such as replacing & copying the flash chip. And firmware/software changes to support the extra memory.
Also assuming an electronically compatible chip is available. I'll be experimenting with that soon.
BTW pricing on such chips are < $3. So it is a cheap upgrade if it's feasible.
I imagine the extra memory could be but to good use in other ways as well.
Thoughts?
