dboomer,
I know this is an incredibly old post, but I am having numerous dropouts with my G90 setup. I am using the C/D antenna positions, I have the terminators in place, and I have it mounted in a wooden rack. When I drop signal I lose all green LED's, and get all red LED's on the tight most meter. I also do have my pack hanging from my guitar strap.
Any help would be greatly appreciated.
