<h1>D-STAR repeater interference</h1>
<p><font face="Verdana">Edition 52 of the International Amateur Radio Union Region
1 VHF/UHF/uW newsletter highlights the interference problems caused by
uncoordinated <b>D-Star repeaters</b> operating in the Amateur
Satellite segments.</font></p>
<p><font face="Verdana">The front page of the newsletter, edited by
<b>Michael Kastelic OE1MCU</b>, says The Cavtat conference has already
recognised the frequency requirement for digital voice, and the bandplans have
been adjusted accordingly.</font></p>
<p><font face="Verdana">We see, however, further development in this direction,
with rising number of users. In some countries, this leads to uncoordinated
growth, with D-Star repeaters operating even in the 2m satellite segment.<br>See
</font><a href="http://www.dstarusers.org/repeaters.php" target="_blank"><font face="Verdana">http://www.dstarusers.org/repeaters.php</font></a></p>
<p><font face="Verdana"><b>The situation is deplorable. We complain about
interference in the satellite segment caused by pirates and telephony systems,
while blocking the satellite segment ourselves, not to mention interference due
to irregular repeater shifts</b>.</font></p>
<p><font face="Verdana"><b>Whenever a new D-Star repeater is to be set up, it
must operate on a coordinated frequency pair, even if this means that an
existing analogue repeater has to be switched off for this purpose. I urgently
request all VHF managers to monitor the developments in their countries and to
use their influence to redress the situation as required.</b></font></p>
