Well tell that to the FCC and ITU. This is not the only mode with some restrictions, but just keep the power lower than you can output, and it will work without sucking up everyone else's bandwidth. Trying to use rules for commercial signals and those used for amateur radio signals sometimes muddies the waters too. But the main thing here is that this band will always change Region 2 and US use of it, so the mod becomes a necessary evil. A magnifying glass is needed along with a steady hand or use of a zero pad vice solder bridge.
