Chuck,
The Pulsars and the pearls are so similar over the vast majority of the sonic range that I have to believe that something else was at play here.
By the way, and I admit that this is a real pet peeve...why do you insist on putting all those apostrophes in your writing (i.e. making it the possessive case when you actually want the plural form)? You used the damned things six times and got it correct twice ("the Pulsar's carried the Pearl's sonic signature"). I swear, the English language, or rather the use thereof, is going to hell.
