We use a piece of audio over ip software for our STL which cost about £200 and a £25 per month virgin contract each end.

> 25watts is enough to cover considerably further than 5km if you get the location right, and if there is not a strong local interferer - and Saddleworth (Key 103 TX location the last I knew) is  a LONG way from Macc.  I help at an RSL station in S Glos and we get out considerably further than 5km on the same power!
> Power has a surprisingly small effect on coverage area - you could double your power and scarcely detect the difference.  Geography (ie: hills) is far more important factor.  I strongly suggest you consider alternative transmitter locations if you have not already. This is relatively easy with the right computer coverage predictions tools used wisely.    If you have your transmitter co-located to your studio, it's unlikely to be in an optimal location - meaning you'll need an STL (studio to transmitter link).  Sounds scary and expensive, but it needn't be (but could be with the wrong choice!).
> As Ian says there are numerous suppliers with solutions out there.  Plug time - have a look at www.a-bc.co.uk.  Other broadcast consultants exist!

> DAB is part of the future of digital radio, not the only part.. DAB accounts for more digital listening than all other digital platforms, and more people listen via the telly than the internet... Internet radio isnt the sole future of radio, i know loads of "everyday" people with FM and DAB sets.. but the only internet radio i have ever known is owned by a real hardcore radio bod..

> However as purely community stations this is a difficult situation. We are currently in a no mans land of digital switchover will it ever happen or not (according to the CEG report) and the current status quo seems unlikely to change in the forseeable future. The current government has far too many other problems on its plate and it being a political hot potato with very little real reason/benefit for a kicking. I personally think that in that situation people will see over time that DAB is dead in the water and will be overtaken by internet radio listenership increasingly in cars.
> Where does that leave the community sector, well we carry on as best we can although some smaller community stations will fall by the wayside but I would encourage those stations with coverage problems to push their internet broadcasting instead.

> I think the concept of Community according to OFCOM need to be re-visit. I believe the licence system need to take into consideration of the real need to the community. How local is local before it starts to compete with the commercial sector? And is such competition always a bad things? How about the need of the dispersed community? The current licence system does not service communities which are large in number nationally but not concentrated enough in a single geographical area to apply for a community licence.

Out of the 16 ………… only 4 of them are listening to Canalside with some of the others (possibly through habit and influence from parents) listening to the local commercial station ………………………… however …… as mentioned last week / pointed out / moaned about yet again / made to look like a professional complainer which I am not ------------ 9 out of the group don’t listen because THEY CAN’T !         some of them live in Macclesfield, which, as the crow flies is at most 2 miles outside the pathetic 5km limit <> 25 watts etc etc ‘’not enough to blow your hat off’’   I wouldn’t mind, but Bollington is surrounded by 2 miles of fields N/S/E/W     surely this area cannot be included in the figures of the 5km ??
