every journey starts with the first shovel full of dirt

the clay digs well
mike loves to play in the mud


there was one death during the project

setting up for the base section

checking out the 6 meter beam
this is what a X-7 beam looks like when you take it out of the box
the 145.29 repeater RX and TX antennas


another view of the assembled X-7
hauling up steel

this is the front row seating
