Debugging QCX issues, using cheap pocket scope, DVM or built-in DVM. With 40m QSO at the end

Описание к видео Debugging QCX issues, using cheap pocket scope, DVM or built-in DVM. With 40m QSO at the end

I bought this low cost DSO150 ("DSO Shell") pocket scope from AliExpress for under $20 incl shipping.

This video is about debugging techniques for when your QCX construction didn't quite result in a working QCX. The methods described and demonstrated with the cheap 'scope are also applicable to more advanced 'scopes.

Also shown, are how to use a cheap DVM, and even the built-in DVM on the QCX, to carry out debugging of the Receiver section.

Finally I transmitted some CQs on 40m CW and after the third CQ, had a nice QSO with Nick LZ1NG.

QCX is a 5W CW transceiver with very high performance, lots of advanced features and built-in test and alignment equipment. It costs only $49. See http://qrp-labs.com/qcx for more information.
