Heres a nicely constructed web site on the Titanics radio operations.

This telegram gave precise details of the massive icefield already in the path of the ship. The surviving officers of the Titanic claimed that they had never seen the signal. Various theories have been advanced over the years as to why this terrible oversight occurred.
Yes very sad indeed.....

Its too bad they didnt have more advanced type radio stuff back then.... (A loud VOICE MESSAGE coming over the air warning them of the ice might have been heard better i dunno)
