The pessimistic values for 'Fraction of earth-like planets that evolve life' and 'Length of time a civilization communicates' are crazy low, too. We can assume that if a planet is earth-like, it is HIGHLY likely that it will evolve some kind of life, even if it's just some single celled organisms or something.
And we ourselves have been communicating with radio signals for over 100 years already -- I'm sure that we will continue to communicate via that and other sources for as long as we exist.
