Ofcom, the Super Regulator, is holding a consultation on Licence Exemption of Wireless Telegraphy Devices.
Walkie Talkies or as they're officially known as Private Mobile Radio (PMR), are allowed to operate in license exempt status in the band 446.0 - 446.2 MHz. Previously this was split into to bands, 446.0 - 446.1 MHz for Analogue PMR446 equipment and 446.1 - 446.2 MHz for Digital PMR446 equipment.
Ofcom is proposing to make the whole band available for both analogue and digital PMR446 equipment, whereby: -
- the band 446.0-446.2 MHz for the use of analogue PMR 446 with a channel plan based on 12.5 kHz spacing where the lowest carrier frequency is 446.00625 MHz
- the band 446.1-446.2 MHz for the use of digital PMR 446 with a channel plan based on 6.25 kHz and 12.5 kHz spacing where the lowest carrier frequencies are 446,103125 MHz and 446.10625 MHz respectively
- the band 446.0-446.2 MHz for the use of digital PMR 446 with a channel plan based on 6.25 kHz and 12.5 kHz spacing where the lowest carrier frequencies are 446,003125 MHz and 446.00625 MHz respectively as of 1 January 2018
- analogue PMR446 equipment operating in the frequency range 446.1-446.2 MHz should use more robust receivers as specified in ETSI TS 103 236 or equivalent technical specifications
This would allow any device to transmit max 500mW while NO fixed basestations are allowed and the maximum transmit time would be 180s, This would all come into effect in Jan 2018.
Ofcom also wish to change mandated exclusion zones around radio astronomy sites for level crossing radar to that of co-ordinated exclusion zones i.e. level crossing radar in the exclusions zones could be used with the coordination of the Radio Astronomy sites. The methodology, decision and appeal processes to determine whether a device can be deployed in the coordination zone is to be agreed between the rail network operators and the Radio Astronomy service.
The current exclusion zones are
| Site | NGR | Exclusion zone |
| Jodrell Bank | SJ 79650 50950 | 20 km |
| Cambridge | TL 39400 54000 | 20 km |
| Defford | SO 90200 44700 | 20 km |
| Darnhall | SJ 64275 62265 | 20 km |
| Knockin | SJ 32855 21880 | 20 km |
| Pickmere | SJ 70404 76945 | 20 km |
DECT equipment has been license exempt for a number of years, operating in the band 1880 to 1900 MHz. Currently the document exempting the equipment states that a handset connects to a basestation and it is proposed to just change the to a short range device (SRD) to make it more applicable to handsets that aren't connected to the telephone network.

Misfit have produced the prettiest wearable for a while, the original Shine tracked steps and was one (if not the) first to do automatic sleep tracking. It was a small disk (27.5mm across and 3.3mm high) which contained the electronics and a changeable CR2032 coin cell which lasted for about 6 months. It came with a silicon strap and a silicon magnetic clip so it could be worn on the wrist or clipped on to a t-shirt, bra, shoes, trouser pocket or wherever suited the user. It's also possible to buy socks and t-shirts with a dedicated Shine pocket and a necklace too. It links back to the Misfit app (Android and iOS) using Bluetooth 4.0.
Now the Shine2 is out it's bigger (it's 30.5mm across and 8mm height) and comes in matt black (carbon back as Misfit describe it) and rose gold. It's also 50m water resistant. The original Shine had 12 white LEDs around the edge and the have been upgraded to RGB LEDs, there's also a 'buzzer' inside that can notify you of various things. The battery is still a CR2032 which should last for around 6 months and Bluetooth is now 4.1 which allows for faster data transfers.
The Shine2 can now wake you up by its buzzer (you set the time in the app), the original Shine had the smart alarm feature, but you'd need the phone by your side. It can now also notify you of calls and texts.
The strap and clip unfortunately don't feel as well made as the smaller ones with the original Shine, but then there'll probably be a slew of new accessories for you to spend more money with Misfit.
Having used the Shine2 for a day, sync'ing definitely seems faster, though you definitely notice the size increase.
Still a very pretty wearable compared to most.
It retails for $99.99 from the Misfit Store (they do ship to the UK using DHL so add shipping costs and import duties/VAT).
Ofcom, the Super regular has published a report on how it has worked with Haringey Council to remove equipment used for Pirate Radio broadcasting from buildings operated by the council. 19 stations were closed in 2014.
Ofcom and Haringey estimate that this has saved the council £90,000 in enforcement and maintenance costs. Ofcom is meeting with other councils on the 3rd of November to report their findings from the Haringey cooperation and if this is rolled out across London could save councils £1m per annum.
Though Pirate radio is illegal it can form a basis for community radio, unfortunately it can cause real issues and NATS has reported 55 incidents of interference from Pirate station. There have also been complaints from emergency services and licensed commercial users.
There are schemes in place for local broadcasters to legally broadcast and Ofcom has even allowed DAB stations to be set-up using off-the-shelf hardware and open source software which means a DAB station can be set-up for around £6,000. These use Linux and efforts from OpenDigitalRadio and commercially available software defined radios.
Pirate radio has been groundbreaking in the past and it will be a shame if all Pirate radio stations disappear, but if Ofcom genuinely allow more open access using local commercial DAB multiplexes maybe it won't matter.
