Kenwood V71 / D710 microphone extender cable

Jef - N5JEF
 

This is the properly shielded cable for extending the microphone from the radio base of a Kenwood TM-V71A or D710[G]A.  It solves the problem of a ticking sound sound in the transmitted audio that you may (or may not) experience if you try to extend your microphone cable with a simple Cat-5 or Cat-6 cable.

The ticking comes from the Kenwood microphone's keypad matrix clock.  Rather than choose a wiring scheme that would have allowed use of standard twisted-pair shielded cable, the Kenwood engineers wired the connections such that the clock signal is paired and twisted with the microphone audio--thus the noise induction.

I've also seen particular Kenwood microphones that exacerbate the problem, maybe a higher current clock signal...

Note that Kenwood does not list this this cable separately.  It is included as part of a more comprehensive extender kit that has more than what you might want and costs more than you might want to pay.

Here's the properly shielded microphone extender cable, 4 meters long, as a stand-alone item.  [You might also need a simple RJ-45 to RJ-45 coupler that you can pick up at Home Depot or the like.]
