Hi Group, I have been putting together a node based around the Beagleboard XM and the LOX board and I am getting some strange noise being added to the signal by asterisk. it basically manifests itself as radom noise on the received signal from the radio (ie audio input) signal, but it is not there when the ID or other internally generated signals are present (ie no received audio). I have tried removing the audio connectors from the BB and listening with a set of headphones and microphone connected directly to the BB then keying it via the radio and still the noise is present... it is as if a filter or something inside asterisk is adding the noise. If some one could shed a little more light on the operation of chan_beagle and where this noise might be coming from that would be most helpful! Thanks :-) Andrew Gilbett andrew.gilbett@gmail.com VK2XAG
