Hello all,
I was reading over the Kenwood D74 code in https://github.com/kk7ds/chirp/blob/master/chirp/drivers/thd74.py and noticed something peculiar with the MEM_FORMAT specification.
Looking closely at the channel information starting at offset 0x4000, by my math each of the channels takes up 40 bytes. This, combined with the 16 bytes of padding for each "group" places 6 channels in one 256 byte page, preventing channels from spanning pages makes sense to me. Then, there are 210 groups/pages. This is where things get odd. 210 * 256 = 53760, plus the offset of 0x4000 places the end of this region at 70144 (0x11200), which overlaps with the "names" section that starts at offset 0x10000.
Am I missing something?
Thanks, Jacob
