As promised, after a few hours of fun riding the QRP transceiver imported from China came the surprise, the blessed did not work. By using some testing instruments I have done the verification of all resistors, capacitors and inductors. I came to the conclusion that one of the ICs is faulty. In short, this is not the time I'll be trying a DX with 3 Watts. But soon I will be importing another and maybe I have more luck.HIHIHI ...
After four months of waiting, the qrp CW kit arrived in China for the 40-meter band. I'll mount it and after testing I should post the results here.
