I knew as much, really. What I'm getting at is something Doug
McDonald mentions on a regular basis - we don't have a mult-path
problem, per say, but a low signal problem. Correct me if I'm wrong,
but I believe there are very few stations running at or near full
power. And all the while, we blame reception problems on multi-path.
