+UK call signs have two parts:
+
+- licence level and regional locator
+- three letters unique to the operator
+
+The prefixes for licence level are as follows:
+
+| Prefix | Level        | Example |
+| ------ | ------------ | ------- |
+| M7     | Foundation   | M7ABC   |
+| 2x0    | Intermediate | 2E0ABC  |
+| M0     | Full         | M0ABC   |
+
+> Note that for intermediate (and intermediate only), you **must** include the
+> regional locator. The second character ("x") is a placeholder for the country
+> code
+
+The regional locators are as follows. Their inclusion is mostly optional,
+particularly if you are in England and contacting others in England, unless you
+hold an intermediate licence in which case inclusion is mandatory.
+
+| Code | Region           | Pneumonic                            |
+| ---- | ---------------- | ------------------------------------ |
+| E    | England          |                                      |
+| W    | Wales            |                                      |
+| M    | Scotland         | Think "Macdonald"                    |
+| I    | Northern Ireland | Think "Ireland"                      |
+| D    | Isle of Man      | Think "Douglas", the capital         |
+| J    | Jersey           |                                      |
+| G    | U                | "U" is the second letter of Guernsey |
+
+Some examples:
+
+| Call sign | Meaning                        |
+| --------- | ------------------------------ |
+| ME7ABC    | Foundation, England            |
+| 2M0ABC    | Intermediate, Scotland         |
+| MD7ABC    | Foundation, Isle of Man        |
+| 2J0ABC    | Intermediate, Isle of Man      |
+| MU0ABC    | Full, Guernsey                 |
+| MI0ABC    | Intermediate, Northern Ireland |
+| MW7ABC    | Foundation, Wales              |
+
+## Suffixes indicating operation type
+
+These are also optional but can be useful - indicated by a slash after the call
+sign.
+
+| Code | Meaning                                            |
+| ---- | -------------------------------------------------- |
+| /M   | mobile: car, pedestrian, inland waters             |
+| /A   | alternate postal address                           |
+| /P   | temporary: a field or rally event with no postcode |
+| /MM  | maritime mobile (vessel at sea)                    |
+
+For example: MM7ABC/M would mean "Foundation, Scotland, mobile" and 2E0ABC/A
+would mean "Intermediate, England, alternate address".
+
+## When to give your call sign
+
+You should state your call sign as "frequently as is practicable". Good
+occasions:
+
+- calling CQ
+- making contact with someone you've found from CQ
+- changing frequencies
+- changing supervision
+
+## Supervision
+
+You can let other people transmit using your call sign under your "direct
+supervision". Anyone doing this must understand the conditions and limitations
+of the licence they are transmitting under and operate in accordance with them.
+
+## Emergency use
+
+In cases of disaster or emergency, you may allow a member of a user service
+(emergency services, St. John Ambulance, Red Cross, government department) to
+transmit using your equipment.
