UK

The UK now has 3 classes of licence.

These are:

Foundation, Intermediate, and Full.

None of these require the passing of a Morse exam, due to the effort of Bruce Perens, and his No Code campaign.

The only difference between the classes is the amount of power they can output.

Foundation: 10W max
Intermediate: 50W max
Full: 400W max

However, this does not mean that a Full licence-holder can use 400W on any band - there are various restrictions based on frequency, and location.
