Just for the sake of interest I thought it would be good to explain how to add up these options as well, I know I was a little confused myself when I first saw the extra bit being used in the APX:
As with the older radio families, you add the digits in the example above for whichever options you need, so if we wanted G806 and G996 we would add [1+8] and this digit in the Flashcode would be a "9".
And if you then wanted to add W12 it would be [1+2+8=11 and convert to hex] "B".
Where it gets tricky is if you want to add something plus the "G" option, so this is the table for all possible Flashcode combinations after "G":
G+1 = H |
G+2 = J |
G+3 = K |
G+4 = L |
G+5 = M |
G+6 = N |
G+7 = P |
G+8 = Q |
G+9 = R |
G+A = S |
G+B = T |
G+C = U |
G+D = V |
G+E = W |
G+F = X |
Note that the letters "I" & "O" are not used so as not to be confused with one & zero respectively.
This seems like a dodgy patch-up job to me, unless of course there's such a thing as Base-24 integers, which I believe would be called "eicosa-tetra-decimal" (no I'm not making that up and don't ask me to pronounce it)!
God only knows what funky scheme Mother will come up with if they ever start using the 6th bit?
Technically speaking, a 96-bit (8-bits per byte) Flashcode should look like "090A04020708-020101060902-3" not "9A4278-211692-3"
Hopefully it will be a while before they do need to utilize another bit but when they do I suspect the Flashcode format will have to change, seems like a variation on the millennium bug... something written decades ago when nobody ever imagined we'd need more than 4-bits?
