N2GSA mobile

In the late 90s a career change pulled me away from my ham radio hobby and friends.

Recently, I decided to get back on the air.  I still have little time and my antenna trees are now gone so I decided to build a mobile station featuring my own design cage antenna as well as high power in my sub-compact, computer dependent, plastic-mold, 2011 Honda Civic.  What could go wrong?

This is my current mobile set for 75 meters: I’ve gotten 5-9 reports running under 5 watts but, of course, I can run much more than 5 watts.

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 4 12-volt batteries 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 live in a group 27 size battery box also in the trunk.  A suction-mounted “pod” powers the amplifier on and off while indicating voltage and current.  A 3KW cross needle SWR meter is included.  A separate meter pair monitors voltage and current consumed from the 12 car system.

Here is the dash
