Uploaded this video again. Hope my text is better visible now.. Here a demo of my new toy the QCX mini. I&build this radio a few days ago. The boards are very small but putting all together was&a problem using the detailed instructions by Hans Summer, G0UPL. It took me about 5 hours to complete the radio. At first startup I noticed that the audio amplifier did&work. I had to exchange the tiny dual OpAmp IC10. First cutted all the leads close to the components body and then desoldered all lead ends from the tiny pads. Another problem arose. Still no audio. Using the debugging instructions in Hans&debugging QCX video, I discovered that the connection between U9 pin 1 and C21 was lost. I made a wire bridge using a piece of the magnet wire which was in de kit. And here it is! A very nice QRP radio with many features. Conditions were poor last saturday but I managed a nice two way QRP QSO with SA6AUT. Marc was using his Mountain Topper also a great rig. His antenna was a Groundplane. 72/ 73 Durk PA3BYW
