"....I assume you never had that popping noise before you tried to install the Echo Board correct."

"I have an older connex 3300 and it has a loud pop when you key and unkey the mike...."

"I wonder if it might be the echo board causing it."

"turning the echo off doesn't effect the pop."

that's because the "pop" has nothing to do with the echo board. the "pop" is caused by a leaky electrolytic capacitor in the receiver muting circuit.

thanks for referencing my site @:
