Don't have a Pro3, but...
On the Pros, turning on some NR will help the popping. Unfortunately, the
effect goes away within 15 seconds on the Pro and Pro2. I hear it will persist
on the Pro3, so turning on some NR may be your solution. Let me know if it
Also, an external audio filter helps, like the QF-1A. Too bad you have to do
that on a $3K DSP IF rig!
