Clint,

I looked at that as a possibility, did a cursory look at an MFJ auto-tuner
schematic, then decided that it was too easy to make one with spare parts
and heat shrink. I would hate to spend $20 plus shipping - only to have to
cut off the heat shrink on the MFJ cable, disassemble, do surgery to
replace the Molex, and put on new heat shrink if I chose poorly.

Using the home brew cable, my 7300 and 7100 both work well with the KAT500
which I use with a KPA500. Next projects will be to make a patching switch
to pop between the two for when I do simplex DV on HF.

I have not tried to use my KX3 with the KPA/KAT500 combo, but assume it
would be easy.

Jack - etal - I checked my parts and did not have the 4 Pin Molex needed,
or the 2.1mm power plug. In looking for the Molex connector I found the
cable which is exactly what is needed. The connectors and the wiring are as
specified in the manual. When I first looked into it I thought the sleeve
of the 3.5mm Stereo plug was left open but it was pointed out to me that it
is in fact also ties to pin 4 of the Moles which is ground.

You are very correct about the $20 plus shipping but I figured I would have
to order the other two connectors and pay shipping on them also. One of the
joys of living "out in the woods" is being able to string wires and install
towers any where you want, but when you need a part you get to pay
shipping.
