If it satisfies you then great. Also if this is a one way, just RX, why not leave the COS always keyed in simpleusb. Maybe I don't get the whole picture but if it is a private just to iaxrpt that should work. iaxrpt is full duplex in that you can send commands and audio downstream even if the other end is keyed.<br id="FontBreak"></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">http://www.crompton.com/hamradio</font></b><font style="font-size:16pt;" size="4"><br></font><br><br><div>> From: bmcintosh@paceprofessional.co.uk<br>> To: arm-allstar@hamvoip.org<br>> Date: Wed, 5 Aug 2015 00:58:47 +0100<br>> Subject: Re: [arm-allstar] New RPI2 installation IAXRpt drops out.<br>> <br>> <br>> <br>> Hi,<br>> <br>> First of all apologies for sending out earlier mails under the <br>> silly "digest" subject header. I don't use lists very often and <br>> this slipped by.<br>> <br>> Secondly, thanks very much for the rapid help and support.<br>> <br>> I don't want to move to using COS for two reasons. One is that <br>> I have already purchased four soundcards that were from <br>> different origins and all use the dreaded blob construction. <br>> Looks like virtually all do these days. The vendor of the ones <br>> you have listed will not ship to the uk. The other reason is <br>> that the radio, which is part of the team's set, does not have <br>> COS available.<br>> <br>> We can always just up the budget and get something suitable but <br>> here in the UK, mountain rescue is unpaid voluntary work and <br>> the budget is accordingly tight. Another alternative is some <br>> point to point audio streaming and a simple GPIO remote <br>> operating program over ssh. In one sense using asterisk for my <br>> problem is a bit of a sledgehammer to crack a nut. But iaxrpt <br>> looks really good and easy to use as a dispatch console and <br>> that's what drives me to use the full-blown apt-rpt solution.<br>> <br>> So cogniscent of your advice - the receiver must present COS <br>> even for a half-duplex remote access system, I thought I'd try <br>> the usbradio solution and dsp COS. I was actually expecting it <br>> to be poor after all that I've read, but in fact it seems to <br>> work a treat. I've only done some basic bench testing so it is <br>> early days, but the quality does seem good enough.<br>> <br>> Again, because of the soundcard procurement problem, for the <br>> PTT I've used the PI gpio and the channel variable/event <br>> handler solution outlined a few times by others on the list. It <br>> was a little tricky initially, with timing issues causing a <br>> lock up. Remember I'm just operating a transceiver, not a <br>> separate rx / tx combination and since I am using squelch COS <br>> detection, when I go into TX from iaxrpt, the system thinks <br>> that the receive channel is occupied and tries to perpuate the <br>> TX forever.<br>> <br>> Anyway, all resolved now and the system working perfectly the <br>> way I wanted it. Doug, you sure have saved a lot of work with <br>> your image and your support. I'm most grateful.<br>> <br>> <br>> Very 73<br>> <br>> Bernie<br>> GM4WZG<br>> <br>> <br>> _______________________________________________<br>> <br>> arm-allstar mailing list<br>> arm-allstar@hamvoip.org<br>> http://lists.hamvoip.org/cgi-bin/mailman/listinfo/arm-allstar<br>> <br>> Visit the BBB and RPi2 web page - http://hamvoip.org<br>> <br></div> </div></body>
