Dave,
Katydids and crickets are similar but the song of this Katydid is unique and unmistakable. Not a single cricket comes close to making this call. It is generated from the male and the sound is only altered in frequency depending on Temperature and Relative humidity. It is unmistakable and the loudest of all insect calls in North America/Hawaii as well far exceeding the Coqui song by a long shot. Until one sits in your yard near your window and pipes up, you'll not know how begnign the coqui song is. Not even our speakers can generate the decible level of this Katydid call at the recorded frequency, it will overload your speaker diaphram if you crank it up. Here's the link to a great site that adresses the Conehead Katydid and crickets etc.

Here's some more facts about them...

"At about a yard away, its sound is in the 90 decibel range -- the level produced by a motorcycle." THIS IS ONE KATYDID!

"On some nights, the frogs’ chorus in the park reaches 70 decibels – about as loud as a vacuum cleaner." This is a whole chorus of Coqui frogs, not just one, of which amounts to very little.
