Your sample image in the repository starts:

My factory image, as well as every other dump I've checked that I've done, starts:
00000000 50 33 31 31 38 35 ff ff 00 00 00 00 00 00 00 00 |P31185..........|

I now understand that P31183 is the HD8, P31184 is GMRS, and P31185 is HAM.

But I have confirmed that TIDRADIO_TD-H3.img does start with P31183, I wasn't making it up. It also says "Welcome TD-H8" — So I think that your test image might actually be an H8 image?

Should I just replace it with an image from the new firmware, or do you want to do something more like have multiple versions for multiple firmware releases?

I have TX220 implemented and have successfully set the bit in my radio. Now that I understand how this works, I should be able to make fairly rapid progress on the rest of these settings.

I did see this in the TD-H3:

_tx_power = [chirp_common.PowerLevel("Low", watts=1.00),
chirp_common.PowerLevel("High", watts=4.00)]

According to my manual that should be 2W and 5W respectively. Do you prefer separate commits for such things, or is it less work to do it all together?

Also, I've seen mention that the firmware is upgradeable, but someone said that they only give it to you if you are in a facebook group. I'm curious about this, as not a facebook user...
