In the late 90s I made a career change which pulled me away from my ham radio hobby and friends.
Recently, I decided to return to the hobby. I still have no time and my antenna trees are now gone so I decided to build a high power mobile station in my sub-compact, computer dependent, plasti-mold, 2011 Honda Civic. High power? What could go wrong?
This is my current mobile station setup for 75 meters
here I am setup for 160 meters – notice the denser wound coil
The station currently consists of a dash-mounted Yaesu FT817ND QRP radio along with a desktop legal limit amplifier constructed by W6PQL in the trunk. The amplifier requires a single 50 volt D.C. source. That source is a string of 4 12-volt batteries which are charged from the automotive 12-volt system by way of a voltage converter. The single voltage source aspect and the “over-design” is what led me to select this amplifier.
Batteries and electronics are all in a group 27 battery box also in the trunk. A dash suction-mounted “pod” controls and monitors the 50 volt system and includes a 3KW cross needle SWR meter. A separate meter pair monitors voltage and current consumed from the car.
Here is the dash
