Specifically on a rig like the Kenwood TS-570S, how much of a difference would a desk mic, such as the Kenwood MC-60A, make versus the stock hand mic? I have never used a desk mic before so I have no operating experience to base a decision on. I run a low budget/power operation so I'm trying to do what I can to get the most reach with what I have. I just optimized my antenna set up so now I'm on to the mic. Thanks.
