I've not been able to determine how Broadwave can point to an Icecast.. it's designed as 'standalone'..accessed directly...it's its own server.. and works quite well in that mode.. maybe I'm missing something....
Steve, try the free M3W or butt encoders from the HowTo page
http://noaaweatherradio.org/howto.html and point to wxradio.dyndns.org
we'll pick up your feed and get it on the pages. The website actually will make as many connections as folks click. Any connections other than 2, in your case, will probably result in 'no response', I don't know how that would work. I've broadwave Pro, which has a higher limit, on my main feed, and have never noticed an issue, or had one reported to me..
I've made some additions, modifications on the howto page, Mostly in the Quality section...including external antenna suggestions.
In adding and testing stations, testing encoders, etc, I've discovered some things, learned some things, and revised some of my opinions an assumptions... resulting especially from some close work with some newer streaming folks..
Notably: There is a wide range of "volume" levels across the many stations,... might check my suggestions, and look at your settings...
stations with a lot of noise on reception might consider actually raising their bitrate to 32 or greater. For sure, please try to send both channels, and peak volumes at -12 to -6 on average with your level indicators.... (your ears will fool you.. use the indicators)
Edcast is simply not producing, overall, consistent quality across the board, as some of the other encoders. Try the M3W, or butt... right now I think the M3W may have the edge... based on my local testing...that could change... but I definitely feel that edcast/oddsock users might consider changing encoders... .
