[Elecraft] K3 and W2IHY EQ Plus!

[Lance Collister]

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.

73, Lance
