<p dir="ltr">I think it does. I think you are saying that the COR and decoded PL signals are to be combined in the radio (or someplace else) before being presented to the COR input to app_rpt. In my case the COR input on the usb fob.</p>
<p dir="ltr">If this is the case, what is the purpose of the CTCSS input in the fob mod instructions that is separate from the COR input?</p>
<p dir="ltr">Since there are separate inputs for CTCSS and COR on the modified usb fob I thought there must be a variable to set in rpt.conf to set Rx Active = (COR + PL). And maybe even Rx Active = (COR or PL). (Note to others:AFAIK Rx Active is my made-up variable and not a Asterisk/rpt.conf variable)</p>

You need to do that entirely in the radio. The radio supplies the COS (when a RX signal comes in with the PL frequency set in the rig) which is a high or low going signal. This is applied to the COS input of the FOB. On the DMK URI it would be pin 8. On a modified FOB it would be the COS line.<br><br>If this line goes low with a RX signal you set - carrierfrom=usbinvert - in simpleusb.conf<br>If it goes high with a RX signal - carrierfrom=usb<br><br>ctcssfrom=none<br></font><font face="Tahoma,sans-serif"><br></font><font face="Tahoma,sans-serif">Does that answer your question?</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"><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>From: <a href="mailto:colecaz@gmail.com" target="_blank">colecaz@gmail.com</a><br>To: <a href="mailto:arm-allstar@hamvoip.org" target="_blank">arm-allstar@hamvoip.org</a><br>Date: Tue, 3 Feb 2015 21:25:04 -0700<br>Subject: [arm-allstar] Receive PL control with simpleusb<br><br><div>I’ve looked all over and can’t find the method to enable the need for Rx PL when using simpleusb. There is a diode labeled for that function in the fob mod instructions and opening or grounding it does nothing. All I can presume is Rx PL defaults to off and COR to on. While I’m asking, is there a way to disable the COR requirement? This is useful if you just want to run PL squelch control only.<BR> <BR>Thanks<BR> <BR>Cole, AA7RD<BR></div><br>_______________________________________________
