I doubt there is much difference between the C5000 and C6000.4I1RAC wrote: ↑Thu Feb 20, 2020 2:07 amRetevis RT8, Retevis RT3, TYT MD-380 and MD390 all still use C5000.
The newer MD-UV380 and MD-UV390 use C6000.
There's also the MD-2017 which is essentially the same as the Retevis RT82, which I believe also use the C6000 chip.
Maybe it would be easier to port there?
The C6000 has FM processing abilities, which the C5000 may not have, but they are not used by the GD-77 and we have no documentation on how to use the FM facilities.
The GD-73 uses a C7000, but that is completely different as it seems to contain a CPU inside the DMR chip hence the GD-73 does not have a separate CPU chip.
What RF chip does these other radios use. I thought perhaps the MD-380 used the same RF chip as the GD-77, i.e the AT1846S, but perhaps it doesn't
