Changelog

Band Atlas follows regulators, operator notices, GSA reports and band databases. Every day the server compares these sources; a change goes to human review first, and only once confirmed is the data updated and recorded here. Every country is re-checked at least once a quarter, and a country past that date is flagged on its page.
