CHIRP

Dan, I have an Alinco 635T and I'm a software engineer. so I would love to help with this. Can you point me to documentation about developing a generic module for radios? Thanks.

Hello,

Do you have any news with theses radios ?
I'm having two of them, and it would have been great to be able to use CHIRP with these !!

Thanks,

Quentin

Does this look like a reasonable first attempt to talk to the radio?

@directory.register
class DR635Radio(DRx35Radio):
    """Alinco DR635"""
    VENDOR = "Alinco"
    MODEL = "DR635T"

    _model = "DR635"
    _memsize = 8192
    _range = [(350000000, 174000000), (335000000,449000000)]
    _power_levels = [chirp_common.PowerLevel("Low", watts=5.00),
                     chirp_common.PowerLevel("Med", watts=20.00),
                     chirp_common.PowerLevel("High", watts=50.00)]

    @classmethod
    def match_model(cls, filedata, filename):
        return len(filedata) == cls._memsize and \
            filedata[0x64] == chr(0x00) and filedata[0x65] == chr(0x00)

I know that it has been a while, but life is getting in the way. So don't get too excited, but I have a question:

I was sniffing the USB traffic between the DR-635 and my computer, and I think I understand (somewhat) the banks and their structure. But the label of each memory bank baffles me: they are string of 6 characters, but they are stored in a somewhat cryptic way. For example:

CALL2M
is stored here (Hex):
30 33 43 33 41 34 35 34 35 33 32 34 36 30 30 46
that represent these characters:
0 3 C 3 A 4 5 4 5 3 2 4 6 0 0 F

CALL70
is stored here (Hex):
30 33 43 33 41 34 35 34 35 33 37 33 30 30 30 46
that represent these characters:
0 3 C 3 A 4 5 4 5 3 7 3 0 0 0 F

NWS
is stored here (Hex):
30 34 37 35 30 34 43 30 30 30 30 30 30 30 30 46
that represent these characters:
0 4 7 5 0 4 C 0 0 0 0 0 0 0 0 F

For both CALL2M and CALL70, you can see C, A, a double character (0x35, that I imagine represents the L) and the correct 5th character (2 or 7).
But what about the rest? And what are the other values in the middle?
And NWS does not seems to fit that pattern.
Ideas? :-)
