Uh oh! Did someone get another Barix box for their primary STL? They make nice toys for "oh crap" links because they are cheap, but they aren't very good for real FM broadcasting full-time links, especially music. Fun things like glitches due to packet timing and other stuff cause issues with them, where a Tieline or Comrex similar type of unit won't. Also, mp3 isn't great for music transmission. Mpeg is old. There is better ways to do things these days compression-wise. Of course, the real thing is to use no digital comression in the first place. Cascading digital comression crap on the air makes me cringe!
