I am also having problems with this same issue. Where my feed drops out for 15 to 20min at a time. Is this a problem on my end or something else out of my control?

I recommend that you use a tool called Ping Plotter to monitor the network path between your computer and the audio server your audio is being sent to. If the program is running the next time a drop occurs you can send me the data files its generates for me to look at to see if I can see where the problem occurred.
You can download the program by going to
http://www.pingplotter.com/downloads/pngplt_std.exe
After you install it and run it:
- Enter "audio9.radioreference.com" in the "Address to Trace" field in the upper-left corner of the window.
- Change the "Trace Interval" value to 1 second.
(optional) Click on the horizontal line that is displayed above the small graph in the bottom-right area of the window and drag it up to make the response time graph larger.
- Select Options from the Edit menu and then select Auto-Save. Put a check in the "Auto-save data" checkbox and then click on the Apply and OK buttons.
- Click on the Trace button in the bottom-left corner of the window.
The next time your feed goes offline, see if the graph in the bottom-right area of the window indicates any problems (the response time graph should look different than it did when you started the program). Also, e-mail me the files in the "C:\Program Files\PingPlotter Standard" directory that begin with "audio9..." which would contain data from the timeframe when your feed went down. The files are written every 30 minutes and the starting time for each file is contained in the filename.
