[cma-l] Community Radio on AM

[Two Lochs Radio]

Certainly easier to put up the aerial system for DAB! 

But of course a lot more digital multiplex signal creation gubbins is needed before the transmitter, and the transmitter amplifiers are a lot more expensive at any given power than for AM or FM because of the much higher perfomance they need for digital signals (I believe the cheapest option for DAB transmitters at the moment is to use under-run small DTV transmitters).

  It’s hard enough to make ends meet on FM yet alone AM. 

   

  Let’s face it, these days no one is inclined to tune in and most don’t even know what the AM button is for! 

   

  The only way AM may work is by having exclusive mass appeal content, such as football, broadcast to an in car audience. 

   

  Although I’ve not done the analysis, I suspect the cost would not be too much more for broadcasting similar as a popup service on a regional DAB.

  I updated our own internal record of Community Radio stations today with the most recent additions.

  This is based with acknowledgement on Ofcom's published TX Parameters and shows that out of the 267 individual CR transmitters (as opposed to the number of broadcasters) licensed, 231 are currently on air.

  I will happily pass this document on to any interested parties that message me.

  At the same time I looked at the number of CR transmitters operational on Medium Wave (AM) and the power they are using.

  There are just seven out of that total of 267, - two using 100W EMRP, two at 70W which is the normal maximum allocated to a CR, one at 10W, one at 4W and the last which we know well at 1W.

  This illustrates I suggest the level of uptake of AM - that Ofcom is offering as an alternative where it says that no FM frequency is available.
