Incorrect subghz frequency bands for Dominican Republic region (DO) #3714

Closed emiltejeda closed 2 months ago

emiltejeda commented 3 months ago

Describe the bug.

The subghz module does not allow transmitting frequencies in the range ~433Mhz, saying "Transmission is blocked". According to the INDOTEL Dominican Institute of Telecommunications page 36, this range is allowed for amateur radio (Aficionados), this also match with attribution of ITU Region 2 Dominican Republics belongs to. image

Reproduction

  1. When the region is determined as Dominican Republic.
  2. Navigate to Subghz -> Region Information and see that the ~433Mhz range is not listed.

Anything else?

Using ITU region to determined the correct frequency for regions where not information is available might be a better option than defaulting to 312.00 - 315.25 MHz and 920.50 - 923.50 MHz as it seems to be the case at the moment

@emiltejeda good catch. I've updated region data for Dominican Republic. And yes, moving to ITU region zoning by default make sense.
