Need a cable for Kantronics KPC-3 to Yaesu FTM-3100

[Kevin Otte]

The KPC manual predates the prominent use of modular connectors on radios.

Looking at the Signalink reference [1], it appears your radio uses an
RJ-11 mic connector. From there I found my way to a likely cable source
[2], though it's a bit pricey. You may be able to extract the
information you need from the diagram. It does appear that RJ11 and RJ12
are the same physical connector, just not using all the pins [3].

I wasn't able to discern much from the manual about the data jack, so
it's probably wisest to avoid it for this case.

The KPC-3 user manual leads me to believe that I need to connect the cable to where the microphone enters, but there is also a microUSB port on the back of the 3100 labelled "Data".  Is the Data port just for connecting to Chirp like programs on my computer, or can the KPC-3 connect to it?
