Thanks for the suggestions about mic presence Jim. Yes, the mic on my headset is set so it is directly in front of my lips - as close as it can be without touching. The problem I have here is that the amplifiers are directly behind me, so the mic is also aiming that direction when I am talking into it. However, the W2IHY Noise Gate is extremely effective, works well, results in excellent audio reports and I am very pleased with the current setup. As far as I am concerned, I do not currently have any problems with my current setup.
