Cars, Grounds and Radios

So I managed to get a little done over the weekend. The grounding for my HF radio has always been a little unsatisfactory to me. So I set out to improve that a little. Currently I only have a stake half buried into the ground below my vertical antenna.

 To improve this I have added 4 radials of equal length at as long as possible within my yard. I know that 4 radials is not ideal, however I am expecting a significant improvement over the current system. One of the biggest concerns I have is with my connection point.

This is where the joint between the radials and the wire that will connect to the bracket for the antenna. Unfortunately at this point I tried to heat up my soldering iron and it just won't heat up. So I'm going to have to see if I can borrow a soldering iron from somebody.

So seeing as I couldn't do anymore out here I decided to put my VHF Ham set into the Jeep. This was one of those projects that I got a little excited about so I don't have any photos of that. But I still have to mount an antenna so I'll get some pictures then.

After I finished setting up the radio I decided to chase some wires that are attached to what seem to be microphones in the cab. Chasing those lead me to this little box:
Chasing the wires from the other end of that box lead through the firewall and eventually to this box under the bonnet on the passenger's side:
Upon unplugging this and removing it from the car I was quite surprised by what I found on the opposite side of that box.

So this was not really expected and thankfully off and not activated, otherwise we could very well have had a very exciting time getting to this stage. I have it off and on my desk at the moment so I'll see if there is anything useful or interesting and I might put it back in. Otherwise I will see if I can remove all of the wiring that it has, just to minimize the spaghetti mess inside the car.
