These days, many people prefer FT8 or WSPR for QRP. However, it is fun to see where an ultra-simple rig can reach. This has been on before, but with Es so good, it will certainly get all over Europe. As with all simple circuits, it is a compromise.
Although I find it hard to believe, this circuit dates back to 2012! It is an ultra-simple CW transceiver for 10m. It is capable of improvement, I am sure. Mine was made "dead bug" style. You can always use the reverse beacon network to see where you are reaching.
