Project: Fabricating a Anderson Powerpole to 3.4mm dc connector for the Kenwood TH-F6A

In our prior post, "Project: Hacking the Nomad 7 Solar Panel for Amateur Radio Use", we explained how to replace the stock 12Vdc 8mm male connector with the more useful Anderson Powerpole connector.

In this post, we describe how to make a pigtail cable to connect the Kenwood TH-F6A triband HT to a 12Vdc power source via an Anderson Powerpole connector. As our starting point, we purchased a Kenwood PG-2W cable from Universal Radio. The Kenwood PG-2W cable comes with fuses already installed.

Kenwood PG-2W

Step 1: Slide on a short length of heat shrink tubing

Slide on a short length of heat shrink tubing over both the tinned ends of the PG-2W cable.
The tubing will be used to dress the cable and provide a little strain relief.

Step 2: Solder on Anderson Powerpole contacts

Solder (or crimp) on the Anderson Powerpole contacts onto the tinned ends of the PG-2W cable.

Step 3: Install the Anderson Powerpole housing

The positive wire is clearly tagged on the PG-2W.
Install the Anderson Powerpole housing such that the positive contact is inside the red side of the housing.

Step 4: Test the cable

Using your voltmeter, confirm that the positive contact on the 3.4mm dc connector is connected to the red Anderson PowerPole contact

Voila! That is how we fabricated our very own pigtail to connect the Goal Zero Nomad 7 solar panel to the Kenwood TH-F6A radio for the purpose of recharging the radio's battery.

Hi there, I have a Nomad 7 and have tried to charge my F6a with it. However, when I plug it in the charge lights on the F6A light up momentarily then turn off. I suspect not enough current, but you say you were able to make it work. What am I missing?
