Ultimate3 QRSS kit - boxing it all up

After the inital build and testing (a 1W 50Ohm dummy load resistor) and some output tests on my scoop and frequency counter, it was time to box it all up.

I bought a ALU case which is made to mount a euro format size PCB with a height of 55mm.

A simple PCB containing a simple 7805 lowdrop power regulator with a few capacitors. make it easy to use every general 6 to 9 volt DC power adapter. A piece of RG174 cable is making the RF connection from the board to the BNC output terminal (yes I like to work with BNC connectors in QRP projects).
