This morning, I came across this memory on Facebook showing a 4m transverter I designed and made some years ago. It was published in SPRAT, the magazine of the GQRP club.
There is absolutely no way I could do this now! My fine motor skills are basically shot and soldering anything is unbelievably hard.
Not one to be beaten, I do experiments that I can still do that do not involve building as much as possible.
