While I visited the Ham Radio in Friedrichshafen, I bought another kit for a QCX QRP Transceiver, this time the 40m version. I won't describe the whole build process, see my detailed description of the 20m version that I built earlier, here.
Here just a few pictures, and the special case I put it into.
Also some additions, like extra heatsinks and an audio amplifier and a small speaker.
After mounting the IC's and capacitors ...
Finished board, mounted in a D-LINK Access Point box. Note the bigger heatsink for the 5V regulator.
Heatsink for the three BS170's, glued on with Superglue.
Preparing the cover, which holds the two external pushbuttons
Adding audio amplifier and small speaker, for monitoring without headphones.
This is what it finally looks like ... it's still a kind of "wireless access point", since it gives you access to wireless communications on the 40m band !
A bit hard to see, but on the top left corner are an ON/OFF switch, a DC input connector, and a PTT output for controlling an amplifier.
