Hy, I have a network with WIFI communication and VHF/ HF channels. I have integrated asterisk in the network using SIP, ZAP and IAX2 channels for WIFI communications, but I don't Know How I could integrate the VHF/ HF channels. I have heard speaking about app_rpt project, but I don't Know very much about this. Could I integrate VHF/ HF c...

I recently installed Icecast2 on my XP Home Laptop. My goal is to get the audio from my vhf/uhf scanner, whose audio out is connected to the laptop's mic port, out as a stream so I can listen to it when away from home (like from work). I can hear the scanner fine through the laptop's speakers, but although I've read the documentation for the Icecast2 server configuration, I...

I wanted to see if there was anything reasonable in price out there yet that performed an RF to IP bridge via asterisk. What I mean by this is callers from PSTN can be patched to a UHF/VHF radio and vis-?-vis. I know there is an option available for the Avaya systems but it?s a little out of the price range I?m looking for (~$200/channel). Has anyone out there found a stable way to do this? Thanks!

...en unable to identify any hardware bottlenecks. The only thing that does help is to suspend the animation for a while by bringing out another game window (e.g. tactics) and then returning. The improvement, if any, lasts for 10 min tops. I'm using wine 1.0.1 on Ubuntu 8.10. Thanks in advance, vHF [/img]

...tat package, increasingly used as a free-open source alternative in radiiotracking and animal habitat selection studies, already has base functions to deal with trajectories in time and space, both as regular samples (e.g. data from GPS radio tags) and as irregular ones (as in 'classic' VHF radiotraking). The implementation of the algorithms devised by Nams could widen the range of analytical instruments that already make adehabitat an almost complete tool. Moreover, the author of the sole existing software to do fractal analysis (V. O. Nams [0]) has expressed no objection towards...

...ns? It does not seem related to the known issue in the mge-shut man page but rather that the UPS does not respond properly (or the OS is dropping data but I don't see any errors about it). One other possibility is that noise is being seen on the serial line (this system drives a high power VHF radar) - I have asked someone onsite to check the cabling but it would be nice if NUT could be adjusted to be more tolerant.

...with the 2.6.24-21-eeepc kernel. For chart plotting I run SeaClear_2 (SC) under Wine. SC communicates as it should with my GPS via a Keyspan USB to serial dongle, both sending and receiving works with this device. I am also running the small app AISMon under Wine. This app decodes AIS data from a VHF reciever via the computer's sound card. (AIS=Automatic Identification System for ships). Also this program seems to run as it should. AISMon has a possibility to output AIS data to a COM port and in SeaClear_2 there is a possibility to receive AIS data from a COM port (other COM port than the...

I'm looking into costs and feasibility of moving a live feed from a FM radio station from the station to a point that's past the usable range of their radio signal. It's a rural location and Internet service is not available at the station. If the destination was closer or their transmitter was more powerful, I could avoid this step and just plug in a radio, but.... My best idea so

The disaster in the Gulf coast and the less than optimal initial response suggests to me that citizens must shoulder more responsibility for emergency management. Communications loss must have played a large role in the failures that occurred. I can't help but wonder if there are fewer ham radio operators today and that if there were more, maybe they could make a difference in future
