Without touching iaxrpt, the audio returns.<br>> <br>> So I have been playing around further.<br>> <br>> My aim is to use iaxrpt to operate a remote radio. No repeater, no telemtry.<br>> It is an emergency radio located in a remote mountain area and is to be used<br>> for mountain rescue communication with the rest of the team using simplex<br>> handheld radios. <br>> <br>> I'm not using any form of COS. This particular model of radio doesn't have a<br>> signal available, but it shouldn't matter. COS is used to determine when a<br>> repeater should tansmit. This is not a repeater. The only time it should<br>> transmit is when pressing the Iaxptt PTT. At all other times iaxrpt should<br>> receive the audio stream from the receiver, even when it is squelched. i.e.<br>> an audio steam that is quiet.<br>> <br>> When I use rpt.conf in duplex=0 then I have the problem of audio dropout<br>> after a while. Maybe soe kind of timeout, but it is random, sometimes after<br>> 10 seconds sometimes after 2 minutes.<br>> <br>> So I tried it in duplex=2. The tx of course was on permanently because there<br>> is no COS signal from the receiver and it thinks that the absence of COS<br>> means a signal is present on the receiver that should be rebroadcast. That<br>> makes sense. Out of curiousity I disconnect the PTT wire so apt-rpt thinks<br>> that it is in transmit on a duplex repeater, but the radio itself is<br>> effectively disabled from trasnmitting.<br>> <br>> Of course the receiver is still feeding its audio to apt-rpt and in fact,<br>> now I am able to operate iaxrpt for as long as I want to listen to the<br>> signal. The drop out peoblem has gone away. Of course its no use, because<br>> I've not got the PTT functionality any more because I put it in the "wrong"<br>> duplex mode for my circumstances - but I thought it was an interesting piece<br>> of evidence.<br>> <br>> Three questions:<br>> <br>> Should it be possible to remotely access a single radio in half duplex by<br>> means of iaxrpt without a COS signal being available ? <br>> <br>> Next question, if so, why can't it be done with the RPI2 image.<br>> <br>> Do you think it is worthwhile trying usbradio and detecting the COS in order<br>> to make it operate more like the usual configuration that is out there ?<br>> <br>> <br>> Thanks and kind regards<br>> <br>> Bernie<br>> GM4WZG<br>> <br>> <br>> So, I need to go back to half-duplex and fix the problem. rpt reload<br>> exit<br>> astres.sh<br>> exit<br>> <br>> <br>> > -----Original Message-----<br>> > From: arm-allstar-bounces@hamvoip.org <br>> > [mailto:arm-allstar-bounces@hamvoip.org] On Behalf Of <br>> > arm-allstar-request@hamvoip.org<br>> > Sent: 04 August 2015 15:20<br>> > To: arm-allstar@hamvoip.org<br>> > Subject: arm-allstar Digest, Vol 15, Issue 1<br>> > <br>> > Send arm-allstar mailing list submissions to<br>> > arm-allstar@hamvoip.org<br>> > <br>> > To subscribe or unsubscribe via the World Wide Web, visit<br>> > http://lists.hamvoip.org/cgi-bin/mailman/listinfo/arm-allstar<br>> > or, via email, send a message with subject or body 'help' to<br>> > arm-allstar-request@hamvoip.org<br>> > <br>> > You can reach the person managing the list at<br>> > arm-allstar-owner@hamvoip.org<br>> > <br>> > When replying, please edit your Subject line so it is more <br>> > specific than "Re: Contents of arm-allstar digest..."<br>> > <br>> > <br>> > Today's Topics:<br>> > <br>> > 1.
