How simple can a rig be?

This was a challenge I wanted to have a go at. This is probably one of the simplest transceivers one can make. My inspiration came from a 40m rig by W2UW who is now sadly a silent key. My wish was to make it even simpler. My main issue was netting. The RX worked well. This appeared in GQRP SPRAT, although I cannot remember when.

There is a video on the website.
