With that combination which I have, I suggest setting the CMP to a value
of 15 to 17 so as to produce about 3 to 4 bars on the CMP scale. Also,
you will need to adjust the MIC gain value such that you get 4 to 5 bars
on the ALC scale.
Yes, mike-to-mouth position is critical. I'm not familiar with the the
MC-60 and its pattern characteristics. If you like that mike and you
get good quality audio reports then I'd say it is OK. Personally I use
a dynamic mike such as the Shure SM-58 or other like mike. With that,
the "4 finger" rule, being mouth straight on axis with the mike and 4
fingers distance from the face of the mike I find to produce the best
result. At the same time, the closer to the face of the mike, the more
critical the mike-to-mouth position becomes. And if one is too far
from the mike, added mike gain is required and the room noise becomes
noticeable.
Again, mike-to-mouth position and consistency is very important to good
quality audio. Perhaps that is why many use a headphone boom mike. The
mike stays constant with regard to ones mouth as they move around and
look at different things in the room.

Hello guys!
I got my very first amp on Wednesday, a KPA500 and started using it along with
the KAT500 I ordered and a K3S I purchased last month.
Here is my question: I noticed that when I transmit, the power output varies
significantly depending upon how close my mouth is to the Kenwood MC-60
microphone (no batteries in the mic). Is this normal? And how do I make this
more consistent? Try to always put my mouth in the same relative position? Buy
a different microphone?
Thanks,
Michael
