Other then the part about not being able to set levels in software,<br>you are correct. With chan_simpleusb you definitely can set levels<br>in software.<br><br>DTMF detection is definitely available with any channel driver.<br><br>JIM WB6NIL<br><br>> Date: Sun, 13 Feb 2011 17:02:51 -0800<br>> Subject: Re: [App_rpt-users] Beagleboard and USB URI dongle<br>> From: phil.n6tct@gmail.com<br>> To: telesistant@hotmail.com<br>> CC: app_rpt-users@ohnosec.org<br>> <br>> Two questions:<br>> <br>> (1) Do I understand that the main difference between chan_usbradio and<br>> chan_simpleusb is whether or not CTCSS encoding and decoding, squelch,<br>> pre-emphasis and soft limiting, de-emphasis, and audio level<br>> adjustments are available in software?<br>> <br>> (2) Should DTMF digit detection be available with both chan_usbradio<br>> and chan_simpleusb?<br>> <br>> If so, then it sounds like, assuming I have an RX radio that provides<br>> proper audio and does CTCSS detection and COR, then I should be all<br>> set with chan_simpleusb ... yes?<br>> <br>> (Ooops, I guess that was really three questions.)<br>> <br>> Thanks!<br>> <br>> Phil, N6TCT<br>> <br>> On Wed, Feb 9, 2011 at 8:50 AM, Jim Duuuude <telesistant@hotmail.com> wrote:<br>> > Yes, it works quite beautifuly with the URI, in fact it will support 2 of<br>> > them<br>> > *BUT* only with chan_simpleusb.
