<p>Hi</p>
<p>I hope everyone is having a good long weekend. I'm putting this
out there to see if anyone has any ideas.</p>
<p>I have a homebrew 6 headset/mic party line system that is used in
figure skating competitions for part of the judging panel to
communicate during a performance. This was built from what looks
like kit pcbs around 20+ years' ago and it is starting to show its
age.</p>
<p>I have been looking at broadcast / camera operator / studio comms
systems as a commercial replacement. The <a
moz-do-not-send="true"
href="https://www.datavideo.com/global/product/ITC-100">DataVideo
ITC-100</a> product looks like it would do what we want
(although we would probably be looking to by used equipment as I
have to put two systems together and none of this is cheap).
However, the beltpack appears to have a push/hold to talk button
(like a radio) rather than an open / always on switch option. It
seems that the premise for this and other systems I've seen is
that the director / producer can talk to one, some or all
operators and they can respond individually as required. I need a
completely open system where everyone talks to everyone.<br>
</p>
<p>Questions for the group:</p>
<ol>
<li>Is anyone aware of a similar system that could provide 6 to 10
headset/mic comms (wired as wireless is horrible to debug in a
live competition)</li>
<li>Would modifying the beltpack with a bypass switch make sense
or too risky (I'm not sure I want to spend $2000+ on a used
system just to run a test)</li>
<li>Anyone fancy restoring / renovating the existing system :) ?</li>
</ol>
<p>Thanks in advance</p>
<p>Alan<br>
