with Ofcom, because they haven’t been to bad with us) when I said ‘jobsworths’
I was meaning that in loose terms, meaning in general. Jobsworths are these
folk who get rolled out by the DCMS sometimes at our meetings, you know the
ones we mean ‘’’the full of hot air brigade’’’
the junior Ministers for example. They spend two hours telling us what we
already know, have hardly any intention of changing anything, but run a survey
anyway so that the boxes are ticked and then we all just soldier on in the same
old way. If anyone has any doubt about this, look back over the past ten years.

It’s because commercial stations are licenced to use a preallocated and
cleared frequency by Ofcom. Should a licenced station make a case that either
Ofcom’s analysis was wrong, or over time the area has changed, then Ofcom
will need to reflect that by permitting changes to the coverage.<o:p></o:p></span></font></p>

with some development. For example if one could select a frequency or
transmitter of interest and set a filter to show only stations of that
frequency, or of that frequency plus adjacent and/or image channels it would
start to give an idea of potential for interference. Combined with perhaps a
crude free space range indication using semi-transparent overlays based on
on powers and direction templayes it might beging to give a rough feel for the
interference landscape for a given station. But as it stands I don't see how it
does that in the slightest.</span></font><font face=Calibri><span

transmitters to allow assessment of potential interference, it surely
isn't the way to go. As you'll be well aware you need much more than a
simple mapping of potential co-channels - you have to take into account
image channels and the directional power templates of antennas at the very
least, even before thinking about the intervening terrain. You also have
to take into account transmissions in neighbouring countries of course.<o:p></o:p></span></font></p>

<div>
<p class=MsoNormal><font size=3 face=Calibri><span style='font-size:12.0pt;
font-family:Calibri'>Of course, the elephant in this particular room is
not in any case what frequencies are or aren't occupied, but what
parameters Ofcom applies in assessing their potential for mutual interference -
eg should a 99% confidence level or a 90% confidence level be used, should
second adjacent channel be regarded as safe or not? Those are what make
all the difference to the assumed potential for interference between
transmitters. Similarly, is potential interference acceptable for 0.1% or 1% of
the time or location? All these parameters are really what set the
technical bar as to whether or not there are channels available.
Then of course there are strategic and political issues, agrements for the BBC
to have priority use of certain sub-bands etc.<o:p></o:p></span></font></p>

<div>
<p class=MsoNormal><font size=3 face=Calibri><span style='font-size:12.0pt;
font-family:Calibri'>One thing that could be considered for releasing more
community radio frequencies is for Ofcom to reuse channels more closely on
the basis of a mutual agreement between stations that they will not complain
about the remote possibility of mutual interference less than say 1% of the
time in 10% of their fringe. We have transmitters on the same frequencies just
a few miles apart, but terrain-limited with no significant mutual interference
in locations of interest, because we were able to agree not to complain about
our transmitters interfering with each other! A similar thing happens on
96.6 between Nevis Radio (<st1:place w:st="on"><st1:PlaceType w:st="on">Fort</st1:PlaceType>
<st1:PlaceName w:st="on">William</st1:PlaceName></st1:place>) and MFR
(Aviemore) in the Laggan area half way between them. I suspect many groups
would be willing to accept a service that might be subject to a little marginal
interference in some limited locations rather thna no licence at all.<o:p></o:p></span></font></p>

to have, could I suggest you add in the Scottish not-for-profit
stations that operate as non-profit community stations, but for historical
reasons have commercial licences (Cuillin FM, Two Lochs Radio, Lochbroom FM,
Argyll FM, Oban FM, Isles FM). That would give a more representative picture of
community radio cover in the northwest of the <st1:country-region w:st="on"><st1:place
