On May 14, 2004, the MMSN began streaming the net frequency over the internet.  It is intended as another means for non-amateur radio operators to listen to the net, family of boat crews to listen for the boat and a way to monitor the net when you are away from the radio or when you have no propagation to the net control station.  You could also use it as a means of checking your audio quality.  You can check into the net and then listen to yourself on the stream because of latency*.

Notes

*As with any streaming audio on the internet, there will be an inherent lag in receiving the audio.  The audio could be lagged anywhere from 4 seconds to 1 minute, as compared to live on-the-air audio.  This depends on your internet connection, the number of servers to get to the stream and many other factors.  There is nothing that can be done on our end to lessen the lag.

If you are on a slow dial-up connection, you may want to disable any other programs that need an internet connection (email programs) as this will cause the stream to stall or drop-off.  Broadband connections should not experience this condition.
