Does anyone have a link to the xipar source repository? I'd like to take a look how they are doing it. It might be possible to do it via 1588 or some other network time protocol.<br><br><div class="gmail_quote">On March 30, 2016 12:01:38 PM EDT, Joe Leikhim <rhyolite@leikhim.com> wrote:<blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">
Without GPS, how does XIPAR deal with jitter and network latency?<br />

<div>If you looking for the alternative IP voting of the
varuious app_rpt flavors you can try XIPAR: <a moz-do-not-send="true" href="http://www.xelatec.com/xipar/simplevoter"></a><a class="moz-txt-link-freetext" href="http://www.xelatec.com/xipar/simplevoter">http://www.xelatec.com/xipar/simplevoter</a><br />
<br />
</div>
It wont be as seamless of voting as a RTCM, but its much
simpler, doesnt require anything more then PC's, the IP
backhaul and usb radio interfaces with radios capable of
giving discriminator audio.<br />
<br />
</div>
Conventional hardware voting comparators could work but require
the backhaul, which in most commercial applications is 4 wire
e&m voice circuits using either tone signaling or e&m
signaling. (This method of voting is done outside of
allstar/app_rpt.)<br />

Raytheon JPS SNV-12 (Though the future of this product is up
in the air, it was the defacto standard. Uses 600 ohm VF
circuits, IP connectivity needs to be overlaid)<br />

<br />
Motorola Spectra Tac (Obsolete Now Motorola has pretty much
abandoned analog FM technology. Uses 600 ohm VF circuits,)<br />
<a moz-do-not-send="true" href="http://www.repeater-builder.com/motorola/spectra-tac/spectratac-index.html" rel="noreferrer" target="_blank">http://www.repeater-builder.com/motorola/spectra-tac/spectratac-index.html</a><br />
<br />
The above voters all use some method of signal/noise voting.
The JPS SNV-12 and the Raven M4X use DSP to make decision,
while the Spectra Tac was pretty much an analog noise
measurement vs a status tone/audio AGC level. The SpectraTac
does not support non-Motorola receivers unless you know the
"secret sauce" which I am privy to.<br />
<br />
This site has some practical examples of projects that are
simulcast, but by design incorporate the SNV-12 voters.<br />

Are you looking for some more in depth RF design aspects of
receiver voting? I can help perhaps.<br />

FYI There are RTCM /voter systems for app_rpt if you
want to do it right.<br />

<br />
Is there an example voting-RX project somewhere I can
read about?<br />
<br />
Non-RTCM please. I know about the RTCM and I'm
looking at alternatives.<br />
<br />
<br />
Many thanks,<br />
