Choosing A Two-way Radio
Two-way radios, mobile radios, walkie-talkies or whatever name you prefer to use, are an effective
way of communicating. Two-way radios are commonly used by security teams, site managers, event organisers and many
others who wish to stay in contact in an easy and low cost manner.
What To Look Out For
Channels - The number of channels you require will depend on the environment you plan to use the
radios. In built-up areas it is best to select a radio with more channels so you have greater flexibility when
selecting a channel. Entry level models generally offer just two channels with top of the range radios offering up
to 14 channels.
Privacy Codes - Radio channels are open, which can result other users listening in to your
conversations. Privacy codes prevent eavesdropping by scrambling your communication; this is an important feature
when buying two-way radios.
Scanning - This allows you to quickly find all available channels and can be offered as either
an automatic or manual feature.
Licence-free radios - Nicomm.co.uk supply two-way radios which do not require a licence from
Ofcom. These operate on PMR446 which is the personal mobile radio 446 Mhz frequency. To operate other UHF or VHF
radios you will need to buy an appropriate licence. Licences are not offered to personal users.
Range - This is the maximum distance between which radios can communicate. Manufacturers may
advertise "up to" ranges. These will be based on ideal conditions so remember to consider surrounding obstructions
such as buildings, woods and high or low ground as these will significantly affect range capabilities.
Batteries - However much you plan to use your two-way radios, it is better to opt for radios
which can use rechargeable batteries. Remember to also check the manufacturers' estimated battery life.
Hands free - Some radios feature a microphone jack, a lapel microphone or in-ear or headset
microphone-speaker combinations.
FAQ: Is there a limit to how many radios can be linked? - No. You can communicate with an
unlimited number of radios, provided, of course, that they are within range and tuned to the same channel.
