PostPosted: 09:27 - 07 Sep 2011    Post subject: 2 way radio Reply with quote

I've been trawling the net trying to find somewhere local to buy 2 way radios with headsets, but I'm not having much luck, somewhere near Chepstow, although I don't mind going a few miles past Bristol and surrounding areas

I was wondering if anyone would be able to offer some advice.

Since these are going to be useless after next week I'm not wanting to spend a fortune on them, preferrably not much more than £30, or at least something that will hold its value for selling on

I've seen some in argos from about £13 but they don't have any of them in stock and none of them say about headsets being included.

Anyway any help here would be appreciated.

I bought 4 PMR446 radios from Maplin for £50 plus headsets for £20 each.

I may have to go out and about rather than looking online.

had a look on maplin MarJay, those radios looked like they are about £80 each...

You should be able to find some Cobra MT975 locally if you phone round

Before you waste any money, Read This:-
Bike 2 Bike Communication.... where to start

£30 will just about get you ONE half reasonable helmet headset, in high street store (maplins) let alone two headsets AND radios to go with them!

Cheapo PMR's with 'hands free' headsets, dont have much range, tend to have poor reception, AWFUL voice activation, and the 99p headsets that come with them 'free' tend not be be brilliant either in the mic or speaker, and NOT designed to be worn under a helmet, damned uncomfortable... you have button pressing into your eardrum, hook cutting into your earlobe, and a mini mic stuck up a nostril!

'Entry' level PMR based bike 2 bike starts at about £50 a radio, with the Oxford Bike2Bike system... and go up from there, with 'good' bike 3 bike sets more likely around £100 a rider set.

We looked into cheap ones, but you don't get a decent range. We bought these
https://www.ebay.co.uk/itm/COBRA-MT975-MOTORBIKE-MOTORCYCLE-2-WAY-RADIO-INTERCOM-/260753013899?pt=UK_ConsumerElectronics_SpecialistRadioEquipment_SM&hash=item3cb6173c8b

12km range, which is about 7 miles, so if you're going through built up areas or "hilly" places like the lakes you wont lose signal Smile
And it comes complete with everything you need for 2 bikes!

The Cobra's are 'better' PMR's, and more likely to work acceptably, but seven miles? In ideal conditions, line of sight between radio areals; fully charged batteries, on a channel in the lower frequency of the allocated range....

PMR is SERIOUSELY restricted by the meagre 1/4 watt transmitter power limit, and high frequency 446KHz, and incredibly short 'coil' areals that are OH so easy to 'sheild', and REALLY need a good line of sight between them, with such a low transmitter power.... pop one into a jacket pocket, and if your body is between your areal and who ever your taling to, even if tyhey are only a few feet away, you CAN loose comms, on them.

Its NOT the ideal system for voice transmission; its a system developed to exploit the the licence exempt frequency range blocked out for kids radio controlled toys, walkie talkies, baby-monitors, garage door remote controls; alarm key-fobs and that kind to thing, intended to operate over very short range, to do a job, it WASN'T intended for.

For VOICE transmission, over more useful ranges you would want a higher transmission power, and lower frequency band; most of those though are blocked out for 'licenced' use, hence joe public cant just walk into a shop and buy one.... apart from the not QUITE ideal, CB Radio allocation, thats not 'ideal' but far more practical, and allowed sisteen times the transmitter power......

I have got 7 miles out of a pair of CB radio's..... in 'good' conditions.... NOT hand held ones working off a couple of AAA batteries, with tiny little areals.....

Out of hand held CB with coiled up 'rubber duck' areals, working of internal power supply (12v) I have had three or four miles in 'good' conditions......

More usually between 'mobile' CB sets, powered off big car battery, with big, high mounted aerial, mounted high on top of a Land-Rover... is 'about' a couple of miles.......

More usually, between hand held CB, 'around' half to a mile, depending how built up it is....

Now ponder the range of a short areal, low transmission power walkie talkie PMR, working on less robust frequency allocation, and 'in real world' conditions where the batteries wont stay fully charged for long, and the weather wont be most condusive to radio transmission, and chuck in back-ground noise, radio interferance, transmission obstructions and 'stuff....

Using 'reasonable' PMR on a bike, comms can, in normal use, be as little as a few hundred meters... and that is from sets equivilent to the Cobra's in quality....... in 'good' conditions they will offer perhaps half a mile, if you have line of sight, sometimes a tad more, but you cant rely on it.

DO NOT believe the hype of the sales blurb and believe that what they claim under 'ideal' conditions is going to be even CLOSE to what you should see, and presume that maybe HALF is a reasonable expectation. Its not!

For mobile CB in Land-Rovers, in 'ideal' conditions, people have clocked over thirty mile ranges...... between tops of big hills, with line of sight, and low cloud, offering optimal atmospherics, out in the sticks, with little interference, and little traffic on that frequency range..... so 'practically' with more robust system, we see perhaps one fifteenth of whats achievable under 'ideal'....

Brings your 7 mile PMR range down not to 2-3 miles, but the suggested 1/2 mile or so.....
