Hi there. Apologies if this question is in the list archives* somewhere. Does anyone have any experience with running app_rpt on the Beagleboard? In particular, has anyone managed to get it to work with the DMK Engineering URI USB dongle? I saw from the app_rpt FAQ that a faster machine ("CPU speed no less than 1.2 GHz") is recommended for use with the URI USB The Beagleboard-XM runs at 1.0 GHz. I'd be very interested in any field experience, or rationale as to why it is or isn't likely to work. Thanks! Phil, N6TCT * "The list archives" -- are there archives to the app_rpt-users mailing list? I didn't see any with a quick google... thanks.
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. Why dont you wait for the LOX board to become available in production? It wont be long. JIM WB6NIL

Was just talking with dave about this yesterday...and can't wait to try it out. I think, for a simple 1 or 2 repeater facility, may be just the thing (once it's fully debugged and soak-tested) a pretty good way to economically keep a station on the air whilst minimizing the mechanical (disk drives really hate cold weather...) issues that seem to crop up (let alone the cost to build a computer and keep it fed with line voltages...) on desktop and laptop systems. Just my $.02. -- Bryan In this world, you must be oh so smart or oh so pleasant. Well, for years I was smart. I recommend pleasant. You may quote me.
Yes, looking for something simple and reliable for running a Micor with one remote base attached, powered by the station. On 02/09/2011 11:20 AM, Bryan D. Boyle wrote:

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:

Other then the part about not being able to set levels in software, you are correct. With chan_simpleusb you definitely can set levels in software. DTMF detection is definitely available with any channel driver. JIM WB6NIL

Is there a stand alone document or page of info for chan_simpleusb? I would like to try using it. Is it the same as chan_usb but without carrier sense /PL decode? and DTMF decode? And on a standard PC how do you build with this instead of chan_usbradio? Thanks! Steve

Thanks I will give that a try.. What exactly is the difference? which DSP (if all) features do you lose when you use that Interface.. I'd suspect you lose DTMF CTSCC and Carrier decode features.. But I've been unable so far to find the information that specifices the difference.. Do you also lose any encode (transmit) features? Thanks!! Steve
