Types of licenses in the UK
There are currently 5 types of radio amateur licenses issued throughout the UK (soon only 3).
They are:
Foundation: max. 10 W, all bands and modes (except 10m) up to and including 70cm. (M3 ABC)
Intermediate class B: 50W all bands above 30 MHz. (2E1 ABC)
Intermediate class A: 50W all bands. (2E0 ABC)
Full class B: 400W all bands above 30 MHz. (G6,7,8 ABC)(M1 ABC)
Full class A: 400W all bands. (all other G prefixes in conjunction with the 2 letter suffix and M0.5 ABC)….. simple isn’t it? :)To pass from group B to group A, it is necessary to pass the 5WPM test in telegraphy.
Očakáva sa, že v júli na stretnutí WRC v Ženeve bude odstránená povinnosť vykonať skúšky aj z telegrafie (CW ). Akonáhle sa to stane, v UK zanikne licenčná skupina B a automaticky budú presunutí všetci rádioamatéri do skupiny A.
Types of licenses in the US
There are currently 3 types of licenses issued in the US, but not long ago there were 6. So let's look at the remaining three:
Technician – 1500W max, 50MHz and above
General - like Technician, but HF rights are allocated, all bands except small areas which are allocated specifically for the Amateur Extra license group
Amateur Extra – like General but all bands without restrictions
Progression from the Technician license group to the General license group is ensured through a telegraphy test - 5WPM as in the UK.
