I just got a pair of the CM500's and they work pretty good. My mic setting is on 3 to keep from over driving the alc on the radio. Is this normal for this mic. I have Low Z selected and Bias. My Heil elements the mic gain is much higher. -- Mike W0MU J6M CQ WW DX CW Contest 2011 J6/W0MU November 21 - December 1 2011 W0MU-1 CC Cluster w0mu.net
