Bom dia, colegas<br><br>Apesar de já fazer a minha parte no uso da banda dos 70 cm (QAP habitual para contactos locais em UHF) conto nessa banda com: 7 (!!!) portadoras de som de TV por cabo, uma lâmpada de descarga, 4 ou 5 comandos de portões, um dispositivo de rega automático e uma estação meteorológica, uma colecção de portadoras de banda larga que não sei do que se trata (coincidiram com a instalação da TDT no Monsanto, mas de facto sei se existe relação) e por fim WCDMA que inter-modula quase todas comunicações em fonia numa parte da banda. <br>
<br>A somar ao PLC e como julgo que não sou caso único, já tenho a minha dose! Mais uma menos uma... <br><br>Cordiais cumprimentos.<br><br>Jorge Capelo<br>CT2JVH<br><br><br><br><div class="gmail_quote">2009/10/8 Carlos Mourato <span dir="ltr"><<a href="mailto:radiofarol@gmail.com">radiofarol@gmail.com</a>></span><br>

(tipo ZAP)...Se não utilizar-mos cada vez mais o radio, qualquer dia ..."Já foi nossa"<br>

<h1>Military radiolocation system to operate on 70 cm</h1>
<p><font face="Verdana">Canadian Radio Amateurs have been informed that a new
militay <b>Enhanced Position Location Reporting System</b> (EPLRS)
will be operating in the secondary Amateur 70cm band</font></p>
<p><font face="Verdana">From Radio Amateurs of Canada (RAC):</font></p>
<p><font face="Verdana">As described in Schedule I of RBR-4, amateur usage of the
<b>430-450 MHz (70 cm) band</b> is on a no-protection,
non-interference basis. Amateurs may not cause interference to nor be protected
from interference from stations licensed in other services operating in that
band. The same is true in the United States, and amateur operations on this band
in a number of areas of the United States have power limits imposed on them in
order to avoid interference to radiolocation services operated by the US
military.</font></p>
<p><font face="Verdana"><b>Industry Canada</b> has informed
<b>Radio Amateurs of Canada (RAC)</b> that it has authorized the
Department of National Defence to use a digital system called Enhanced Position
Location Reporting System (EPLRS) on these frequencies. The <b>EPLRS system
consists of mobile, fixed, transportable and airborne stations that use 5
MHz-wide spread spectrum channels to provide strategic telemetry information for
military platforms</b>. <br>This authorization is on a no-protection,
non-interference basis, which means that no new restrictions will be imposed on
Canadian amateur operations in this band as a result.</font></p>
<p><font face="Verdana">Industry Canada has informed RAC that there is a slight
potential for interference to amateur radio systems, typically in the form of a
minor audible clicking noise. If Canadian amateurs encounter such interference,
they are requested to report it to RAC at <regulatory @ <a href="http://rac.ca" target="_blank">rac.ca</a>>. The
information reported should include the geographical location, date, time,
frequency and mode being used by the amateur station, and a description of the
interference.</font></p>
<p><font face="Verdana">Questions or concerns regarding the planned implementation
of EPLRS may be sent to <regulatory @ <a href="http://rac.ca" target="_blank">rac.ca</a>>.</font></p>

Eliminate Broadband over Power Line. Salve o espectro electromagnético!. Não use a rede electrica para transmitir dados. Os "homeplugs power line" e a tecnologia "power line" causa fortes interferencias noutro serviços sem voce se aperceber. Diga não à tecnologia power line. Proteja o ambiente<br>
