<p><img src="eps/hpr4214/hpr4214/spectrum24.jpg" alt="closing picture" /></p>
<p>The Conference for Creative Use of the Radio Spectrum in Open
Systems, that brings users of the radio spectrum together. For over a
century, technology has made it possible to transfer more data, faster,
further. Today, wireless technology is everywhere and commonplace.
However, it remains a playground and a ground for innovation for many
communities. The spectrum24 conference provides an opportunity to
publicize projects and to allow the different communities that use the
spectrum to meet in person over a weekend.</p>

<p>The say that in Space no one can hear you scream, but here at
spectrum24 I'm not so sure.</p>
<p>The talk from <a href="https://www.qrz.com/db/f4eob">Thierry Alves
F4EOB</a>, <a href="https://www.qrzcq.com/call/CT2JTZ">CT2JTZ</a> spoke

<p>What do you do when you're not organizing conferences ? Hacking a
project to contrail radios, and a lot more besides, using Linux.</p>
<p><quote> trx-control is a modern and extensible software system for
Linux to control transceivers and other devices over the network. It can
as well be used to integrate third-party applications or databases.
