KDR 444
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. FM with a bandwidth of 16 kilohertz (25 kHz in Norway) is used.[2]
Channels
There are eight channels (originally six).
| Channel | Frequency (MHz) |
|---|---|
| 1 | 444.600 |
| 2 | 444.650 |
| 3 | 444.800 |
| 4 | 444.825 |
| 5 | 444.850 |
| 6 (new) | 444.875 |
| 7 (new) | 444.925 |
| 8 (old #6) | 444.975 |
Channels are wide FM[clarification needed] [citation needed]. Frequencies 444.875 and 444.925 may not be available in some regions (such as Norway); older equipment may also lack these new frequencies. Consequently, 444.975 is likely to be called channel number six on such devices.
European Use
From the 1st of May 2016 KDR 444 is now cleared for use across the European Union, and equipment is now becoming available in other countries.[citation needed]
