PMR radio channels: 8 new frequencies

PMR446 (“Personal Mobile Radio”) is a European standard for licence free wireless communications. Radios (usually “Walkie Talkies”) following this standard are usually very affordable and easy to find. They’re often used by store staff, security guards, traffic controllers etc. Also some baby monitors and toys use the standard.

From the 5th of november 1999, the exempt status of PMR446 is officially in effect in the Netherlands. Because of this, using it doesn’t require a license. Originally there were 8 channels allocated between 446.000-446.100 Mhz with a spacing of 12,5 kHz. The maximum allowed transmitting power is 500 mWatt. This gives you a range of up to 10 kilometers when there’s a line-of-sight. In build up areas the range is usually closer to 500 meters.

Although the use in the European Union is license free, in the United States the frequencies are allocated to radio amateurs by the FCC. So in the U.S. the radios can only be operated by licenced HAMs.

PMR: 8 additional frequencies according to CEPT

Observant members of the Dutch Facebook community “LPD/PMR Nederland” recently discovered that the revised CEPT-rules mention 8 new channels. This gives a total of 16 licence free frequencies.
