The plot shows reception at K9AN of my 200mW WSPR from a quarter wave vertical in an open marshy field environment. Geomagnetic conditions were quiet throughout. 14MHz supports propagation only from midday until mid-to -late evening, and doesn't recover again until the following noon.
Of course, none of this means you should give up. There is ample opportunity to make good DX contacts, especially if you can time your activity well. After all, at only 200mW, this is a pretty critical test of conditions!
