Episode 138 - Tony Fishpool - G4WIF

Picture
When it comes to homebrewing QRP HF radios with simple parts and test equipment, then one of the go-to  guys is Tony Fishpool, G4WIF, current membership secretary of the G-QRP Club in the UK, and frequent contributor to its quarterly SPRAT magazine.  Tony is also a co-author with Graham Firth, G3MFJ, of Simple Test Equipment for the QRPer, and numerous articles on equipment building with attention to detail and budget.  Tony believes, along with his cohorts at G-QRP,  that ham radio does not have to be expensive to be fun. G4WIF is my QSO today.

Tim, search for "Xphase" and there are a lot of people who have documented the project. An example being Martin G8JNJ.

Here is a video of such a device in action. It's pretty impressive.

I still haven't finished mine. Life getting in the way of "shed time". I'll document mine when it's working.

Tim and others interested, I've since finished the noise canceller and I've documented it on my blog at http://www.fishpool.org.uk/noisecancel.htm
