Professional DMR radio

The term Professional radio refers to licensed radio systems which are used by organisations. These operate using signals transmitted by the radio on either UHF or VHF Frequencies. The licensed frequency bands are UHF 400-527MHz and VHF 134-174MHz. In the UK the licenses are issued by OFCOM and can be applied for online. Should you need any guidance on which license you require please get in touch. 


At their simplest a professional radio system could just be one handheld radio transmitting to another, this is often referred to as 'back to back'. This is quick and easy to deploy and can provide reliable voice communications suitable for many applications. However there are drawbacks in that the range is limited by the power of the handheld and the surroundings in which it is being used.


To increase the range of effective communications base stations and repeaters are used. These transmit at a higher power and often use powerful antennae to transmit over larger distances. The drawbacks of these are the need for fixed infrastructure which is costly to deploy. 

Analogue vs digital, most modern radio systems are now digital but most manufacturers still offer a few analogue radios. The main advantages to an analogue radio system is the interoperability between manufacturers and a slightly enhanced range versus digital. The main advantages to using a digital system are the enhanced feature sets which can be utilised including GPS, Text messaging and many other features.
