Microham cabling

I have a couple of Microham cables that go from the K3's to the MK2R+. I am
getting setup to run SO2R and was in the process or hooking up my bandpass
filters and the 6m pre-amp which uses a pin on the accessory port.

I took apart the Microham accessory connector and was going to solder on the
connections I needed for my band decoder and the connection for the 6m
preamp.

Once I got the connector apart, I found they have filled the inside with a
white semi-solid compound. The compound does not seem to come off very
easily. While I am sure this material probably makes the cable better it
sure makes if very difficult for those of us wishing to use the other
features of the accessory connector on the K3.

I haven't decided if it will be easier to cut off the connector and start
over or try to cut away the white stuff with an exacto knife.

A nice value add would have been to bring out the unused connections in a
cable for those other uses.

Just a heads up for others that might have been going down this path.

Re: Microham cabling

Thanks for the heads up Mike!!! I just got the K3R cable and was going to be doing the same thing for
the AuxBus line. I guess MH did this to help keep the wires from breaking of the connector but you are
100% correct, it makes access to the other connections impossible without completely redoing the
connector with a new one.
Doing it this way was a bad move IMHO. I may just replace them connector with RCAs and use my LDG
breakout box.

Re: [microHAM] Re: Microham cabling

That might work and allow for more flexibility if you moved the rig to
another location and were not using the MK2R or other MH product.

Why redo the connector?

Just create jumper cable with a connector to plug in the existing Microham
cable, then a connector to plug into the K3.

Add the wires from the K3 connector you want and pass the wires to the
microham cable connector that microHam needs.

This way you leave the microHam cable intact.
