I have one and use it with a Kenwood THF6a on a mobile node. At first I couldn't get transmit audio. I contacted Advance Repeater Systems. They were really good.  We went through the radio tune menu proceedure and saved the settings.  It just so happened, the problem had nothing to do with the adapter. My THF6a has a flaky external Mic. They caught it other wise I probably would have missed that.  Now when I set up, I have to be absolutely sure the connector is seated and not move the radio. In the radio tune menu I set my audio levels at 500 then use the internal adjustments in the adaptor to fine tune the audio. Works really well.   JK From: Donny Parent <kk4rjy@gmail.com> To: "app_rpt-users@ohnosec.org" <app_rpt-users@ohnosec.org> Sent: Subject: [App_rpt-users] no audio I was wondering if anyone else is having issues with no audio from the node using a portable radio and usb adapter from advanced repeater systems. It flashes green so i know its getting a signal, flashes blue when it receives, and the red light lights up when it TX but it sends out s dead carrier no audio. Ive changed in rpt.conf and usbradio.conf duplex=0 per the instructions that came with the usb adapter but they dont know why im not getting audio. Any input would be great - Thanks!
