RADIO FAQ’s


Q.  What frequencies are available?

A.  The IR-803, 600 and 500 are available with the following frequencies:

     UK - Europe = PMR446 - License Free

     USA - Canada = FRS/GMRS - License Free

     Australia = CB 40 Channel - License Free (IR-803 Only)

     UHF = 410 - 470 Licensed (You will need a license to use frequencies in this band)

     VHF = Licensed  for 803 & 600 models, (Not the IR-500)

If you require a license, you need to contact Ofcom in the UK who can allocate suitable channels for you to use.  We can then add these channels to your radios at any time.


For customers ordering from the USA, Canada or Australasia countries, the appropriate radio channels will be supplied automatically.


Q.  What are the advantages / disadvantages of using a Remote Antenna?

A.  A radio antenna transmits it’s signal along it’s length, not out of the top or bottom (Imagine the antenna pushed through the hole in a really big CD, the CD would represent the signal).  So, when you lay the radio down on it’s back, in among the metal of the vehicle chassis, the signal will barely get out and what little does get out will be mainly going up, down, left & right, not to the front & rear which is where you want your signal to go.

The best place for an antenna is as high as it can go, away from the metal of the vehicle and “if possible” your body.  Strictly speaking, remote antennas are only supposed to be used on Licensed UHF & VHF frequencies as European PMR446 radio specifications state that the antenna should be permanently fixed to the radio circuitry.

The main disadvantage of adding a remote antenna is that with every join / connection between the radio and the antenna, a bit of signal power is lost, so if you can get your radio mounted fairly upright, using it’s original antenna, it will generally be better than adding a remote antenna in a similar position.


Antennas for use in the UHF band (including PMR446, FRS/GMRS and Aus CB), do not need a “Ground Plane” and so you can mount them on non-metallic surfaces with good transmission results.


Q.  How long will the battery last?

A.  Depends on a number of factors, including how much talking you do and what transmission power settings you are using.  The IR-803 and 600 radios come with a high-capacity battery pack as standard, which under normal conditions should be good for a couple of days or more average use.  

The IR-500 has a 700mah battery pack and should see an average day’s use between charges.

Additionally, we offer 12v power adapters to allow you to run the 803 & 600 radios directly from a vehicle.


Q.  How can I get the best performance from my radio?

A.  When using a radio by hand, try to hold it by the body with the antenna upright for best transmission.  Do not hold the antenna or swing the radio by it - it will break eventually !!

For maximum voice clarity, do not speak directly into the microphone.  Hold the radio about 10cm (4”) from your mouth, “side-on” so that your voice travels across the front of the radio, not directly into it, this will give clean, clear, professional sounding voice transmissions.  Shouting into the front of the radio will overload the microphone, giving a garbled, un-intelligible voice.

Whenever possible, try to run the batteries down before re-charging.  Although NiMh & Li-ion batteries are not supposed to have “Memory effect” they will certainly benefit from full and proper charge / discharge usage.


Q.  What “conditions” affect performance?

A.  Mounds of earth, trees and metal buildings, local interference, even heavy rain will all “sap” a signal.  UHF radio signals are generally considered “Line of Sight” which means don’t expect the signal to go through a mountain or round corners !!


Q.  What distances can I expect to achieve?

A.  Don’t believe the performance figures quoted for ½ watt PMR radios with tiny antennas !  We have seen quotes of “up to 5 kilometres” on boxes containing radios that would be lucky to get 500 yards in the “Real World”

As a very realistic rule of thumb, we quote about ¾ mile for ½ watt radios travelling at 70mph.  Our 2 watt radios have been independently reported to get up to 8 miles and we have had reports of over 10 miles from 4 watt settings.  Once again, it all depends on “conditions”.


Q.  Are IntaRide radios compatible with other makes?

A.  Yes.  All our current radios can “talk” to standard radios of other makes.  Our “Technical” section has a converter chart to help with this.  They have standard “Kenwood 2-Pin” headset connections to accept a vast number of accessories.
