<h1>Save Analogue Radio campaign</h1>
<h1><strong><font size="3" face="Tahoma">A National Campaign to
maintain essential traditional analogue broadcast radio for everyday
listening and for use in times of national emergencies.</font></strong></h1>
<p><font face="Tahoma">The pressure is on to replace traditional
analogue radio broadcasting with Digital Audio Broadcasting (DAB)
radio. </font></p>
<p><font face="Tahoma">Indeed, the UK Government has provisionally
set 2015 as the date when the world wide standard frequency modulation
(f.m.) services are to disappear from the Band II 87.5 to 108MHz
(v.h.f. f.m. band), to be replaced with DAB radio transmissions. </font></p>
<p><font face="Tahoma">Eventually, the analogue services on long
waves (198kHz) and medium waves (500kHz to 1.6MHz) will also be
replaced by digital transmissions.</font></p>
<p><font face="Tahoma"><strong>Obsolete radio receivers:</strong> </font></p>
<p><font face="Tahoma">Several million non-DAB equipped radio
receivers could be made obsolete, if the Band II plans are implemented
– requiring people of all income groups to purchase new receivers. The
'digital effect' is already apparent as very few manufacturers now
produce analogue-only receivers.</font></p>
<p><strong><font face="Tahoma">Practical considerations and technical
difficulties: </font></strong></p>
<p><font face="Tahoma">Unfortunately, the Government's plans don't
take into account the large number of practical considerations and
technical difficulties involved with the present forms of digital
transmissions – particularly when radio broadcasting is involved
because of the 'digital delay' effect (known as Latency). The problems
are likely to be difficult to overcome because most listeners use
portable receivers, utilising simple antennas (aerials). </font></p>
<p><font face="Tahoma">So, in response to the Government's proposals
I am planning to organise a national campaign urging the Government to
retain analogue broadcasting on Band II v.h.f. f.m. and on long and
medium waves, while maintaing the DAB radio services on Band III.</font></p>
<p><font face="Tahoma">Please don't hesitate to contact me if you
need further information on the complex problems that are in store for
the radio listener in the UK – if the Government's seemingly
ill-considered plans proceed.</font></p>
<p><font face="Tahoma">Thank you.</font></p>
