I just installed a walkie-talkie haedset into my bucket, and the reception is crystal-clear. This would be a great way to stay in contact with a "spotter" at a con, wouldn't it? I'll have the cord going under my armor with the radio in a pouch on my belt, next to my blaster. I feel happy knowing that I'm making some progress on this.
Oh, a quick update on my armor: I have the "in-between" straps attached. All I need to add to the chest/stomach set is the collar, then I can put the straps along my back to wear it. If you're confused about the setup of my armor, I'll explain it better.
Well, I hope this is a *slightly* helpful topic, peace out.
