We’re good, but not that good!


Here at Radio-Active we have dealt with a wide range of repairs that put our technical skills to the test. But sometimes the radios are just a complete and utter mess that even with our expertise we can’t bring the radio back.

Motorola have released a floater!

Motorola’s new T92 H20 is a licence free twin pack radio that features a waterproof design and rugged construction that will keep you connected with others, even on the wildest adventures. You should definitely get this twin pack if you need to stay connected while on the water, jet skiing, snowboarding, fishing, rock climbing, mountaineering and everywhere else. It also floats!

Bomb on the Beach

A member of the public discovered a remnant of ordnance found on site at Dyfi Ynyslas on the 31st of March, 2018. It was brought to the Visitors centre and the centre was evacuated whilst investigation was undertaken. So this is where the radios came into action as they were used to co-ordinate the evacuation of the visitor centre and the cordoning off of the surrounding area. The HM Coast Guard Borth was alerted and the ordnance was fortunately deemed to be safe.

Situation like this regularly occur at the beach, so the radios are a vital part of the process.

Fancy a quiet day at the beach? Think again!


Ynyslas National Nature Reserve and Visitor Centre, near Aberystwyth stretches over 3 miles and is full of activity, especially in the summer months. The need for radios is a must which is why we were called.

National Nature Reserves are places with some of the very finest examples of wildlife habitats and geological features. As well as maintaining the unique nature reserve, from the boardwalks to the sand dunes, the staff at Ynyslas beach need to keep in contact so they are ready for any situation.

Channel 0 was programmed into the radios which directly links to the coastguards. The weather can change very quickly, strong winds and tides can be dangerous and can cause a need for quick communication to recover stranded vehicles stuck in the incoming tide.

Radios are also used to cordon off areas as unexploded ordnance from WW2 are normally found uncovered on the beach.

The Fixed Penalty Notice introduced by Ofcom

Under new regulations, Ofcom now has the power to issue a fixed penalty notice to unlicensed radio users. This has been put in place to reduce the congestion and levels of interference to legitimate licence holders.

The fixed penalties Ofcom use are sent to alleged offenders by post. They will then have one month to respond. If you receive one, you can choose one of the following options.

  • Pay the fixed penalty of £100.
  • You could make representations to Ofcom to explain why you shouldn’t receive a fine. You are still advised to pay the penalty while Ofcom review your case.
  • You may ask to be tried for the offence by a court.

If you fail to respond to the letter, Ofcom can then decide whether to prosecute you. If found guilty you may have to pay a fine much greater than the amount of the fixed penalty.

Moral of the story, get a licence, its cheaper!

British Bobsleigh and Skeleton Team


The British Bobsleigh and Skeleton Team have been using us as their radio supplier for a number of years. We have recently supplied them with Kenwood TKD340’s and unique programming for the Pyeongchang Games. The radios are a vital part of the team’s training as it allows the coaches to stay in contact with the athletes and other team members for communications up and down the track. It allows for smooth operation and is a vital tool for the success of the team.

We would like to wish them the best of luck!
