I've been going through as many messages as I can find and might have missed the answer to this.
Trying to narrow down the problems.
Digital Vertex radios (EVX261).
When the pit crew keys their mic, there is a bunch of noise that makes it hard to understand anything.
So I assume the source of the noise is the pit crew radio which is battery operated.
We've tried a few different mic/headset combos.
Ideas?
