[cma-l] Community Radio on AM

[Ian Hickling]

I haven't done any real appraisals apart for the Farnborough station which manages about a 2-mile radius in daytime hours which is be barely adequate but does at least cover the core population.I'm not aware of any computer coverage software that will cope with MF - and of course there's the question of exactly the EMRP value - and even more indeterminate - the antenna propagation pattern.
I'm sure other members will  have first-hand information.

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.
