10m in the quiet years

Firstly, 10m is good for Es (sporadic-E) at any part of the solar cycle. In the northern hemisphere May-August are the best Es months. There is a smaller peak around December-January. There are many theories about Es. Also, as mentioned before, N-S real DX can occur on 10m even in the quietest solar periods with no sunspots.

As 11m CB demonstrates, 10m is a useful band for local nets - the proverbial "natter across town". 4W from a converted CB FM rig regularly enabled me to work 30km with a CB halfwave antenna.

Another possibility is a derivative of my Tenbox AM rig. Simple to make and a possible club project? What was done before my stroke is a possible source of ideas.
