A radio station i have some involvment with has summer parties at Mission Bay, Okahu Bay and Waiwera Hotpools half a dozen times a year...
Having the ability to broadcast the party is something that would be hugely beneficial for many reasons...

A laptop with a T3G card running shoutcast seems to be the best way to do it... ie Have the dj/amp plugged into the laptop at the party running the server - then from the MAIN studio connect to the shoutcast server using their adsl and then broadcast out...

For an all day party it would need to stream all day (8 hours). $200 for 500mb should be enough to stream for that long and would be worth it to the radio station.

My questions are - would the streaming quality that would need to be used be good enough for radio?

and... Is there another (easier) way I could do this? If a Harrier had an audio in and a descent sound card, it would be the perfect accessory for a mobile studio.

Perhaps there is a better way of doing it rather than streaming audio over a mobile data network?

Does anyone know the sound quality of push-to-talk? would it be feasable to use p2t to do what I'm trying to do?
