OOOPS!   It turns out I rcvd a followup from the recipient of my approx. 40 meg sound file sent via the link supplied at the start of this thread. It took a while to be rcvd. (it took over 10 minutes to send) but arrived intact and was able to be transferred for air-play at my radio station.

Thanks for the great advice---saving a lot of gas money now in sending it down instead of delivering it.
