Microphone options for a Kenwood TK840 - Help!

[oldmanunix]

I have a great Kenwood TK840 that has a factory microphone that is big enough and
heavy enough to be used as a weapon or a paperweight. Can someone suggest a lighter
weight replacement or one that can be modified to use with this radio? Is a KMC30
usable with the original TK840 6 pin cable?

Thanks.
