Substation band library

The 48 bands this release ships in substation/config.yaml.default, as its own loader reads them, each with the template its type names merged in. A band is scanned by its name, and changed in a configuration file of your own, under bands.

Each band's reception_class groups it below, and decides whether it records out of the box:

How UK law treats listening to this band. general is what Ofcom calls general reception, which anyone may receive: licensed broadcasting, amateur and CB radio, and weather and navigation transmissions. not_general is a service outside general reception, such as PMR446, business radio, marine, military airband, and emergency services, which Ofcom says it is illegal to listen to. unsettled is for bands where the position is unclear, such as civil airband. A band that does not set recording_enabled records only when it is general. This describes UK law and is not legal advice: the law where you are decides what you may receive and record.

A band that sets recording_enabled records or not as that says, whatever its class.

Reception and the law, in the README, says more.
