[App_rpt-users] questions on beagle

We are running usbradio with DSP PL decode on an ACID server, and we've had
no issues. The radio has a Com-Spec tone decoder, which we ignore because
folks thought it sounded too tinny... guess we could have install a
de-emphasis ckt, but it was easier to just "turn-on" the DSP, and not run
simple USB. Not tried usbradio and DSP in the XM, which I'm using with the
DMK LOX. As Doug pointed out different ears hear things differently... I
just go with the majority opinion because my old ears just don't
discriminate well enough to judge :-)


Thanks,

Bob

OK, thanks, that's what I was looking for. I was trying to avoid a Com-Spec
tone decoder or encoder. I may kluge in a Micor Encoder and decoder. Big fan
of reverse burst, etc...

 

But that answered my question, and pretty much as expected. I'm very
familiar with the issues around usbradio in general. I've used it a lot.
What I have always found odd is that same computer, same CM108 dongle, plays
tones, etc fine in windows, but in Linux it is flaky. Too bad, though. The
idea is a good one. I have one "unlisted" node still running this way. Low
(very low) activity, so usable. 

 

Thanks

Beagleboard XM comes with beagle.conf, which is simpleusb like... e.g. no
DSP, relying on hardware PL decode. I don't know if you can use
usbradio.conf for DSP for a PL decode.

 

Thanks,

Folks, will current distros of pickle, or whatever we use on the beagle
boards run DSP for PL decode or noise squelch? I have a BeagleBoard XM and a
BBB, about three months back version. I'd love to tuck one of these inside a
Nokia BSR-450 repeater eliminating its squelch and PL encode/decode (well,
it doesn't have those)???

 

Thanks
