@roadriverrail whoa, high power :)
My radio lives on 5 Watts, ever since I was told, over a decade ago, that my licence was a joke because it only permits 10 Watts. From Western Australia I've spoken to stations all over the globe, most of them whilst I was operating portable with either a vertical or a dipole.
My WSPR experiments are about attempting to discover more about propagation and the various fairytales we've been taught.
I'd encourage you to see where less than 100 Watts gets you!
