By default Allstar responds with a courtesy tone to tell users on that frequency that Allstar is there and active. It does not transmit over anyone only when they stop transmitting like you would hear on a repeater. If it actually does transmit over someone then your COS is probably not working properly. The polarity might be reversed. To test -<br><br>From the L:inux prompt go into the Asterisk client -<br><br>asterisk -rvvv<br><br>Key and hold the PTT of your radio that talks to your node radio. You should not see anything yet. Unkey the radio. You should see the hungup message in the display. If you are seeing the hungup message on key down then COS polarity is reversed. If you are not see it at all either way then COS is not working.<br><br>To reverse COS polarity edit /etc/asterisk/simpleusb.conf <br><br>Look for the 'carrierfrom' line <br><br>It can either be usb for positive going on signal or usbinvert for negative going (around 0 volts) on signal <br id="FontBreak"></font><br><font style="" face="Tahoma,sans-serif">If this does not answer your question unless you explain exactly how you have things hooked up that is the best I can do for an explanation.</font><br><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><hr id="stopSpelling">Date: Thu, 10 Sep 2015 22:22:50 -0400<br>From: tukosei@gmail.com<br>To: arm-allstar@hamvoip.org<br>Subject: Re: [arm-allstar] tones on transmission<br><br><div dir="ltr"><p dir="ltr">I don't understand why the node would key the radio up over a couple of people having a conversation, say HT to HT (locally) other than to annoy the parties that have no idea there is a 3rd radio out there TXing a tone over the start of their conversation.

<div><div dir="ltr"><font color="#000000" face="Tahoma,sans-serif">The courtesy tone goes out to any local device connected to the node. So it would go out over the connected radio. For simplex operation when COS drops indicating an RF station stopped transmitting there is a delay (settable) and then the node TX keys and the courtesy tone is sent. For full duplex at the end of an RF transmission when COS drops the repeater stays keyed for the delay period and then the courtesy tone is sent.<br><br>I think what you were hearing was normal. Courtesy tone is meant to indicate end of transmission and the other party can talk. If you are talking over it then you are keying up too fast. <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: Thu, 10 Sep 2015 20:47:54 -0400<br>From: <a href="mailto:tukosei@gmail.com" target="_blank">tukosei@gmail.com</a><br>To: <a href="mailto:arm-allstar@hamvoip.org" target="_blank">arm-allstar@hamvoip.org</a><br>Subject: Re: [arm-allstar] tones on transmission<br><br><div dir="ltr">The issue I was having was no one was using/ logged into or using the node.

One is to force users to wait until after the tone to speak. This eliminates cutoff of audio due to delays in the system. you should always wait 2-3 seconds to transmit. Fast keying is not a good thing in Allstar. It also does not allow others to break in. The other reason especially on simplex odes is to show that the RX actually heard you. On repeaters Allstar is often used as the controller and thus the courtesy tone would be for the repeater. Most repeaters have courtesy tones.<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: Thu, 10 Sep 2015 16:29:24 -0400<br>From: <a href="mailto:tukosei@gmail.com" target="_blank">tukosei@gmail.com</a><br>To: <a href="mailto:arm-allstar@hamvoip.org" target="_blank">arm-allstar@hamvoip.org</a><br>Subject: [arm-allstar] tones on transmission<div><div><br><br><div dir="ltr">I am trying to eliminate a “courtesy tone” on my setup. It
seems that each time the system hears a radio transmission; it has to transmit
a tone about 2 seconds after the end of the reception. Sometimes, it will
transmit over the person trying to talk (RF) back. This occurs when there is no
one connected to the node.<br>
My setup is using a Pi2 > USB sound card > HT radio.<br>
I tried adjusting some of the .conf files but haven’t found
the setting yet.<br><br><br>Ryan<br>KK4OSG<br></div>
