<body class='hmmessage'><div dir='ltr'><font style="" face="Tahoma">Just to expand on the previous message to Greg here are the pinouts for a simpleusb connection from the DMK URI to the Alinco 144/222/440 series radios with data connectors.<br><br> Alinco DB9 Male DMK URI DB25 Male<br><br>COS 1 8<br>RX Audio 4 21<br>Ground 5 20 (or any ground point)<br>PTT 7 1<br>TX Audio 9 22<br><br>This should be a shielded cable.<br><br>The Alinco COS follows PL. You still need squelch. Experiment with setting it above the default level of 2. A value of 4-7 or possibly more does not significantly lower the sensitivity but greatly reduces the tail.<br><br>The BBB simpleusb.conf file on the image is setup correctly for the Alinco series of radios. Pin 8 of the URI corresponds to the carrierfrom=usbinvert parameter. The ctcssfrom should be set to no and invertptt=0.<br><br>With rxboost=1 the typical rx level is 750 and tx level is 500 set by simpleusb-tune-menu<br><br>If never hurts to put ferrites on both the audio and usb cables. It has solved HF interference problems for me.<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">http://www.crompton.com/hamradio</font></b><font style="font-size:16pt;" size="4"><br></font> </div></body>
