Small helpers we actually use when programming a radio or reading a listing. They are educational — not official Ofcom data, not a substitute for the RSGB band plans, and not a reason to transmit without a licence.
If you are new, start with the guides (lawful listening, first scanner, amateur VHF/UHF). Come back here when you need 8.33 channel numbers, a short band crib, or a lat/long to NGR conversion for a listing.
