[cma-l] Radio Link Transmission systems

Thu Jun 2 11:45:21 BST 2016

Life would be sweet if we had 4G coverage at our TX sites, or even 3G! We don’t even have 2G Edge service for most! However, one will soon be in wireless link range of a fibre-enabled exchange, and that will be a game changer.

Using IP, you can easily stick in a router at the TX with automatic network fail-over. It will pick up your internet stream via a secondary ADSL and /or plug a 4G modem .

not only that but sometimes the studio location can be in a really non suitable position for a transmitter site, and so you have to be situated somewhere else.

Stop hyping on about 5 km it's a radio wave! Besides some stations have special constructions which affect pattern from a perfect circle!

What’s fascinating on this one is that the distance I believe between the Transmitter site and the actual base signal is about two and half miles ….. crikey !   that’s nearly as big as the actual broadcast area !

May I remind everyone ….. 5km !     don’t exceed that or else Ofcom will reach for the panic button the Commercials will chuck all their Toys out of the Pram and you’ll be in danger of broadcasting to more than one man and his Dog and we can’t have that now can we ?? as it just wouldn’t be Cricket. Everyone else pleases themselves but we have to stick to the rules of the fair play award.

Remember, our aka name is   <>   Restricted FM                    LOL       :)

A couple of yogurt cartons and a piece of string normally does the trick and keeps the signal strength to a whimper, and the cost is negligible as well       a fiver (£5) tops

With reference to what Glynn has suggested, if the signal does stray by a few yards then you can always lob a few twigs in the way of it, that also usually does the trick.

Listening to the state of ours in certain parts of Macc, I think someone has chucked a Tree in front of it.

I agree with Bill - if you have perfect line of sight (not even a twig in the way) then a digital 5.8GHz link is the way to go.   It gives you ample bandwidth to deliver perfect uncompressed PCM (ie CD quality) audio - no need for mp3, aac etc compression. 

Rather than the free spectrum though, I'd go for licenced spectrum - for £50 a year fee it should be cleaner spectrum less susceptible to interference. 

A few more details available on our website 'ere <http://a-bc.co.uk/studio-transmitter-links-stl/> .

Hi all

We’re looking for cheap and reliable solutions to get our “on-air” output from our studios in Bradford city centre to our transmitter site a couple of miles away. We’ve got line of site from the top of our building to the transmitter site.

Please let us know cost effective & practical solutions that work for you.

Thanks
