Just dont mess with: GPS, Airline radio, cell phones, broadcast infra, emergency services
If you're blowing double the power for ISM, nobody cares. Your PEP using a yagi is 4x what is legal? Unless you piss off a ham, nobody cares.
And even if you are a ham, and are using 150KHz bandwidth with low power in, say 50MHz (regulation says 40KHz max), again, nobody cares.
And also if above 6GHz (common SDR top end), nobody will notice. The equipment up there is $$$$$.
But damn, you want to piss off hams? Mention bitrate maximums or encryption. You'll never hear the end from the old gatekeeping idiots.
