I've tried several iterations of Linux and have YET to get SvxLink working.... Can't seem to find all the pieces and parts needed to get it installed... Is there a trick to Linux I don't get?

The software you need is SvxLink. It is FREE to download and has all the features you need, and a lot more. In SvxLink you can use the remotetrx function to split RX's and TX's (yes multiple!) between different QTH's. The built in voter can select the best RX. Several codecs are available if you have limited bandwidth to you internet. Dont be afraid that it is running under Linux. To "kick start" your repeater system: Find two computers with soundcards. Install Linux, most linux distribution work fine. (Fedora prefered) Install SvxLink, http://svxlink.sourceforge.net/install.php (If there are questions, see below for support!) Play with it! You can use a PC speaker as the TX and a microphone as RX to start with. Warning! You will probably get hooked by this impressive software. Find more information here: http://svxlink.sf.net There is also a "Live CD" that you can download to test svxlink. Burn this .iso and boot the computer with Linux and SvxLink. NO Install needed to test! http://sourceforge.net/mailarchive/message.php?msg_name=6c9ade2f0812130617u1bbabcc0q7057d8ee23346650%40mail.gmail.com When you get stuck, this is the place to go: http://svxlink.sourceforge.net/support.php 73 de Gus, SG3P http://sk0ct.se/ > Brian; > In general VOIP as an audio link is not very stable if you > do not control the bandwidth loading of the Link.
