The interview was more about my life but I do want to make it clear that although I often represent the front-end of our BBB and RPi2 project there are two others behind it in a big way. Dave, KB4FXC is mostly responsible for the coding and he is very good at it. He really takes the credit for many of the changes including the fix of the delay problem in simpleusb. Chris, W0AMN deserves credit for the setup and weather scripts.<br><br>I guess you determined the delay is the problem? I guess you won't know for sure until the new code.<br><br></font><b><font style="font-size:16pt;" size="4">73 Doug</font><font style="font-size:16pt;" size="4"><br></font><font style="font-size:16pt;" size="4">WA3DSP</font><font style="font-size:16pt;" size="4"><br></font><font style="font-size:16pt;" size="4">http://www.crompton.com/hamradio</font></b><font style="font-size:16pt;" size="4"><br></font><br><br><div><hr id="stopSpelling">Date: Sun, 17 Jan 2016 15:32:09 -0800<br>From: kj6qfs@gmail.com<br>To: arm-allstar@hamvoip.org<br>Subject: Re: [arm-allstar] Extra hang time on my voter node<br><br><div dir="ltr">Doug,<br><br><div>Cool!

<div><div dir="ltr"><font color="#000000" face="Tahoma,sans-serif">Sam,<br><br> I am not familiar with the specifics of the RTCM but it sounds like maybe you are being hit by the delay problem that will be fixed in the next release. The only difference is it is usually a variable delay. You cited a fixed delay? The variable delay is on any simpleusb node but is rarely noticeable on a simplex node. On a repeater you could often have a delay such that your own words are heard when you unkey. It is variable though so sometimes it is there and sometimes not. The new code to come out solves that problem.<br></font><br><b><font style="font-size:16pt;" size="4">73 Doug</font><font style="font-size:16pt;" size="4"><br></font><font style="font-size:16pt;" size="4">WA3DSP</font><font style="font-size:16pt;" size="4"><br></font><font style="font-size:16pt;" size="4"><a href="http://www.crompton.com/hamradio" target="_blank">http://www.crompton.com/hamradio</a></font></b><font style="font-size:16pt;" size="4"><br></font><br><br><div><hr>Date: Sun, 17 Jan 2016 14:32:46 -0800<br>From: <a href="mailto:kj6qfs@gmail.com" target="_blank">kj6qfs@gmail.com</a><br>To: <a href="mailto:arm-allstar@hamvoip.org" target="_blank">arm-allstar@hamvoip.org</a><br>Subject: [arm-allstar] Extra hang time on my voter node<div><div class="h5"><br><br>Hello all, <div>I know this may seem off topic, but I am running the RPi2 image that everyone else is running here, and wanted to ask before I face the "big league" on the other group.</div><div><br><div>I'm noticing a little extra transmitter hang time on my RTCM/Raspberry Pi 2 node.

I have the node set up to be a full duplex link (duplex=0, linktolink=yes, zeroed hang time) <div><br></div><div>I connect to another node of mine (a simpleusb node) and listen to it through my RTCM. When someone unkeys on the other end, I hear their squelch tail, followed by a 1.3 second or so pause before my RTCM unkeys. This tells me there is some extra "stair step" in terms of timing between a node unkeying, and my node unkeying. I played with buffer sizes in both the RTCM and voter.conf. </div><div><br></div><div>Is this perhaps some "flutter-fighting" routine on the other node? Or perhaps some goofy obscure setting on my end? </div><div><br></div><div>Thanks for reading. <span></span></div><br></div><br><br>-- <br>KJ6QFS<br>Sam Skolfield<br>
