Incorrect subghz frequency bands for Thailand region (TH) #3650

Describe the bug.

The subghz module does not allow transmitting frequencies in the range ~433Mhz, saying "Transmission is blocked". According to the Thai website, this range is allowed for amateur radio. In fact, I live in Thailand, and have been receiving signals in this frequency range from various of my RF remotes already, so it seems to be widely used.

Reproduction

  1. Update firmware to the latest version using the mobile app while in Thailand (not sure how the app figures out the region).
  2. Navigate to Subghz -> Region Information and see that the ~433Mhz range is not listed.

Anything else?

It seems to be using the same frequency bands as the Japanese region. I would try to open a pull request, but somehow could not find anywhere in the source code where the "TH" region is even defined.

The region database indeed seems to assign Japanese frequencies to Thailand:

"TH":["F_JP_312","F_JP_920"]

Interesting. Is there anyway to contribute to this list?

This repository is exactly where it should be done. I'll take a look on provided papers tomorrow and update list if our certification lab accepts it.

I've updated region data, should be correct now
