<H1>Operating Practice on FM Satellites </H1>
<P><FONT face=Verdana><STRONG>Ib OZ1MY</STRONG> has written some usefull
operarating hints for those wishing to use the FM single channel Amateur Radio
satellites. </FONT></P>
<P><FONT face=Verdana>Satellites with linear transponders can allow many dozens
of QSO's to take place simultaneously and operating on those is in many ways
similar to say 20 metres, however, things are different for the single channel
FM satellites. </FONT></P>
<P><FONT face=Verdana>With FM sats only one QSO can take place at a time and
they require different operating procedures. When a single channel satellite
passes over densely populated areas they can get a bit congested, so Ib OZ1MY
has posted the following operating guidelines to the AMSAT-BB: </FONT></P>
<P><FONT face=Verdana>This is a short version of an article I wrote in 2000
about using FM (single channel) satellites.</FONT></P>
<P><FONT face=Verdana>Short version:<BR>The golden rule - do not transmit if you
can not hear the downlink. </FONT></P>
<P><FONT face=Verdana>Calling "CQ satellite" 3 - 4 or more times and give the
call and the full locator at the same time is non-productive.<BR>It simply takes
too long time. Experienced operators easily pick out new stations using a short
CQ call.<BR>It is not really necessary to call CQ - just give your
call.</FONT></P>
<P><FONT face=Verdana>Considerate operating practice allows a QSO to
finish.<BR>Many operators on the FM satellites do not adhere to this.<BR>You
very often find a station calling on top of a running QSO, which makes the QSO
take much longer time than necessary.<BR>Often it is because the QSO takes a
long time, which leads to the next "rule".</FONT></P>
<P><FONT face=Verdana>Make the QSO short when the satellite is busy. Valid QSO's
just need to exchange calls and signal report. That is it.<BR>You do not need
locator or operator name. If there is very little traffic OK go ahead and talk
about anything - but not when the satellite is busy.</FONT></P>
<P><FONT face=Verdana>Here in Europe we also have the habit of asking for the
full locator.<BR>I have tried to avoid that, but I have failed in this
respect.<BR>For a terrestrial QSO or in a contest you need the full locator -
but not for a satellite QSO.</FONT></P>
<P><FONT face=Verdana>A considerate operator will make one QSO per pass. If you
are an experienced operator, who has made a lot of contacts before - limit your
contacts to new stations.</FONT></P>
<P><FONT face=Verdana>Do not use the FM satellites to elaborate on the weather
situation in your local area, when the satellite is busy.</FONT></P>
<P><FONT face=Verdana>Give priority to portable and mobile stations if they can
hear the satellite.</FONT></P>
<P><FONT face=Verdana>Give DX stations (rare calls) a chance to get through. I
have witnessed JW stations being "drowned" by local QSO's.</FONT></P>
<P><FONT face=Verdana>Look at your satellite tracking program in order to avoid
calling stations that are out of the footprint.</FONT></P>
<P><FONT face=Verdana>If someone is really annoying - don't try to block their
signal - try to send them an e-mail especially if they are from your own
country.</FONT></P>
<P><FONT face=Verdana>Also respect if people want to use their own native
language. It is perfectly OK to talk Danish, German or any other language, as
long as they do not carry on for many minutes.</FONT></P>
