KDR 444 (Norwegian "kortdistanseradio", Swedish "kortdistansradio", "short distance radio") or KDR, is a licence-free personal radio service in the UHF range used in Sweden and Norway.
It is usually referred to as SRBR 444 (Short Range Business Radio) in Sweden.
Transmitters are limited to 2 W ERP (previously 1 W) in Sweden[1] and 0.5 W in Norway.
Norway requires a radio with fixed antenna to be used with these frequencies.
KDR 444 is specific to parts of Scandinavia and is not cleared for use across the European Union.
