Using Licence-free Radios with Licensed Radios

Here’s the thing. You have a number of PMR446 licence-free radios and a number of licensed radios. You want them to work together and your local radio dealer has told you that it’s impossible.

That’s not strictly true. You could program your licensed radios to work on PMR446. But if you do, you risk a £10,000 fine and up to a year in prison. So don’t do that.

The Solution

The good news is there is a viable technical alternative to risking prison time. And it’s by using the SR-628 cross-band repeater control box by Surecom. Introducing the Surecom SR628. See this diagram.

How It Works

You connect Surecom SR628 allows you to connect a radio to either side creating a 2-way duplex repeater. When you talk on the PMR446 radio, this will be rebroadcast on the Licensed radio, and vice-versa. You need to use one of the radios from each system, but this solution allows you to talk between the two sets of radios legally.

Licence Free Two Way Radios

Licence free two way radios are a convenient way to use two way radios without the worry or inconvenience of obtaining a radio operators licence.

Advantages of Licence Free Radios
  • No licence required – of course
  • Smaller initial cost outlay
  • No call charges
  • No contracts
  • Pre-programmed frequencies, no programming needed
  • Can be used throughout the EU
Disadvantages of Licence Free Two Way Radios
  • Limited range compared to licensed radios
  • Potentially congested channels – many operators use the same channels so interference can be more frequent

Types of Licence Free Two Way Radios

Here at Radiotronics, we categorise these into two headings – Walkie Talkies which are more leisure style radios, and Professional Grade Licence Free Radios which more resemble high power business radios. Read on.

Walkie Talkies (Leisure Style Radios)

Walkie talkies, usually supplied in pairs, are cheap and convenient types of two way radios. They’re usually small radios no larger than the palm of your hand. Here at Radiotronics, we stock a wide range of walkie talkies from both Motorola and Midland. Walkie Talkies are not always used for leisure use – sometimes they can be a cost-effective solution for small schools etc.

Advantages of Leisure-Style Walkie Talkies
  • Usually Supplied in Pairs
  • Cost Effective – Very Low Cost
  • Easy to Use – Preprogrammed & work out the box
  • Most accept either bundled batteries, or alkaline AA or AAA batteries
  • Some models CTCSS to reduce interference
  • No licence required of course
Useful For
  • Camping & Fishing
  • Shooting Sports
  • Paintball Activities
  • Small Schools & Nurseries
What We Recommend

> See the Licence Free Walkie Talkies section on our website.

Business Grade Two Way Radios

Professional-grade licence free two way radios are radios look almost identical to high-power business radios. Business grade licence free two way radios are typically built to the same military specifications as their high-power siblings and are just as durable. The only real difference is that professional-grade licence free two way radios restricted to 500mW (0.5W) and operate on only the licence free radio band.

Advantages of Licence Free Professional-Grade Two Way Radios
  • Same build quality as licensed radios
  • Dealer programmable
  • Almost all models are CTCSS capable for minimum interference
  • Maximum feature set – almost all professional-grade licence free two way radios have similar features to licensed radios
  • Some models are waterproof
Useful For
  • Construction sites
  • Leisure centres
  • Hospitality / Hotels
  • Factories
  • Farms
  • Shooting & Fishing Sports

Vertex Standard Universal / Legacy Battery Reference Chart

Vertex Standard have completely replaced all their batteries with the all new Universal Range.

This means, in a nutshell, that now all Vertex Standard batteries can be charged in the CD-58 charger. This is great as no matter what Vertex Standard radio you buy, they all use the same “universal” charger. But this only applies to the latest version of batteries. The bad news is that if you buy a new “universal series” battery, you’ll also need to upgrade your charger to a CD-58 charging pod with either a PA-55U (UK) or PA-55C (EU) power supply.

Finding the right new universal battery for your old radio can prove challenging. So we’ve created this handy chart. If your battery is missing from this chart it just means there’s no direct replacement battery.

How to Open a Motorola GP340

Motorola 6680702Z01 ToolThere are many reasons you may want to open up your Motorola GP340 which include changing the front cover or cleaning etc.

This article also applies to: GP340, GP330, GP340, GP360, GP380, GP640, GP680, GP344 & GP388.

The good news is that opening your Motorola GP340 is relatively simple. You’ll just need a simple Motorola GP430 Case Opening Tool.

The tool you need is the Motorola 6680702Z01 tool.

This guide is designed to facilitate with changing the front cover when you buy one our Motorola GP340 front cover housing kits.

If you need detailed information you’ll need to download the GP340 service manual.

Front Cover Removal Procedure

This short guide assumes you’ve already removed the battery, unscrewed the antenna and removed the accessory socket dust cover.

All of our GP340 front cover kits come with the internal ribbon flex cable already installed, so here we just concentrate on removing the radio from the cover.

> Note: Fitting the cover is the opposite of this guide.

1. Remove the Plastic Knobs

It’s very important that you remove the plastic knobs on top. If not, this can result in fracturing the knob shafts and cause expensive damage to your radio.

2. Remove Chassis From Cover

Be very careful here. This process should be relatively smooth. If you find it’s very tough to do, you’re probably doing something wrong.

Prise the chassis out of the front cover by pushing upwards from the bottom, using the tool mentioned above. Then slide the chassis downward to remove from the front cover. Be very careful that you don’t snag the ribbon flex cable.

3. Detach the Ribbon Flex Cable(s)

Depending on if you have an option board fitted there will be either one or two ribbon flex cables. You can detach them by very carefully sliding a flat-blade screwdriver under their retaining latch. They should pop up instantly and release the ribbon flex cable. I they do not, do not force them, rethink and reassess.

Motorola 6686533Z01The only way to open a Motorola DP1400 or Motorola CP040 without damaging the casing is by using the correct tool.

The tool you need is the Motorola 6686533Z01 tool.

> We sell the 6686533Z01 for £9.99 on our main website – click here.

Front Cover Removal Procedure

There are just three simple steps to open the casing and potentially change the front cover on a Motorola CP040. The procedure is practically identical on the DP1400.

> Note: This short guide assumes you’ve already removed the battery and unscrewed the antenna.

1. Remove The Knobs

First you must remove the plastic knobs on top. Failure to do this may result in you snapping the volume and channel shafts.

2. Remove the Chassis from the Front Cover

Using the chassis opening tool, starting at the bottom, prise the chassis from the front cover. Be very careful not to strain the front cover housing or damage the chassis. The chassis will prise easily, so if you need to use too much force, you may be doing it wrong.

3. Remove the Speaker
