Changes to digital PMR446 Frequency Bands
The licence-free two-way radio service, PMR446, has provided leisure and business customers with a flexible, low-power two-way radio solution for short-range communications since it replaced its previous incumbent, SRBR, in 1998.
The next development of this technology was when Icom launched a licence-free digital radio, the
IC-F4029SDR in 2005 offering improved audio quality, data capability and increased battery life.
Things changed again when on the 1st of January 2018 the frequency band 446.1- 446.2 MHz was designated for use by PMR446 licence free radios across Europe in line with Harmonised European Standards EN 300 296-2, EN 300 113-2 and EN 301 166-2.
The new frequencies, which follow ECC Decision (15)05, create greater capacity by extending the assigned frequency spectrum for digital and analogue equipment to 446.0 - 446.2 MHz with a channel plan based on 6.25 kHz (digital) and 12.5 kHz (analogue) spacing where the lowest carrier frequencies are 446.003125 MHz and 446.00625 MHz respectively.

The digital
IC-F29DR3 and analogue
IC-F29SR2,
IC-U20SR licence-free PMR446 radios will have this new channel allocation as standard. Previous models of PMR446 cannot be programmed to the new channel allocations.
