Two questions: (1) Do I understand that the main difference between chan_usbradio and chan_simpleusb is whether or not CTCSS encoding and decoding, squelch, pre-emphasis and soft limiting, de-emphasis, and audio level adjustments are available in software? (2) Should DTMF digit detection be available with both chan_usbradio and chan_simpleusb? If so, then it sounds like, assuming I have an RX radio that provides proper audio and does CTCSS detection and COR, then I should be all set with chan_simpleusb ... yes? (Ooops, I guess that was really three questions.) Thanks! Phil, N6TCT On Wed, Feb 9, 2011 at 8:50 AM, Jim Duuuude <telesistant@hotmail.com> wrote:
Yes, it works quite beautifuly with the URI, in fact it will support 2 of them *BUT* only with chan_simpleusb. The CPU does not have the horsepower to do the DSP routines used in chan_usbradio.
