5W CW transceiver

I ordered at QRP Labs the QCX, a 5W CW transceiver kit. It took 9 days to arrive from Turkey to Belgium. The box was checked by the customs, but the content was not touched and no fees had to be paid.

I’ve been working on it for about 10 hours, spread over 3 days. After that, I spent another hour or so adjusting and mounting the external housing. The external housing had to be modified to install a socket for the CAT port that is implemented in firmware 1.03 and PCB revision 5.
