The story

Hi, I am Andy, amateur radio operator N2GSA.  Over 20 years ago I made a career change.  With my unusual and long hours and changing band conditions, I lost touch with my ham radio hobby and friends. When the time came I lost the trees that supported my wires it did not seem that big a loss.

Recently, I decided to return to the hobby.  Operating from home was not a reasonable option but I could build a modern version of my old effective mobile station.  Yes; I would build a new station in my sub-compact, computer dependent, plasti-mold, 2011 Honda Civic and, in addition, I would run high power.  What could go wrong?

The electronics

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 operates from a single source of 50 volts.  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.  4 12-volt batteries create over 55 volts, but good info says the amp will be fine.  The single voltage source aspect and the “over-design” is what led me to select this amplifier.  Batteries, charger, relays and more live in a group 27 battery box -also in the trunk- which I think of as the service module.  All connections go to or thru the service module.  A dash suction-mounted “pod” switches the 50-volt system on and off while monitoring voltage and current usage.  The pod includes a 3KW cross needle MFJ remote sensor SWR meter.  A separate meter pair monitors the controlled current drain from the car itself.  Almost everything is connected to the trunk via cat 5/6 patch cords.  The cords are color coded to where they plug in.

Here is the dash.  My 12 volt meter panel even has a tiny remote control to dim or disable illumination.  The meter and illumination activates and deactivates to indicate charging or not.  Everything is very turn-key.  There are no real “dials” that need to be operated.  I can drive or I can works dials but not both at the same time.  This radio has 4 preset power levels and that is about all I change other than frequency.
