The Scout, being a small radio, can be mounted by something so simple as an
angled piece of board or ply wood with bungee cords to hold the radio case
to the board at a convenient angle for viewing the panel and control
operation with radio angled up from the car floor.
The TT mount is a simple U shaped piece of metal with holes cut out for the
feet of the Scout to poke thru. You could home build something similar from
aluminum sheet, or mild steel with the bending brake at a local machine
