It is always very satisfying to see when someone has taken one of my designs and taken it on to the next stage. In the case of M1GEO, he has made a PCB for a design based on my transverter. It looks so much better than my original! Dead bug build style is fine for "one offs" mind you.
It is quite a while since I was last on 472kHz. I really should try loading up the feeder to my 2m/70cm antenna to see how this performs.
