As I discussed with examples in Part 4 there’s not much point in even bothering if the MUFs between you and the spotted operator are below 28MHz.
As I write (1120utc) the MUFs in most of Europe are too low for (non-groundwave) 10m QSOs [notwithstanding very-weak-signal modes like wspr and ft8 seem to manage]. courtesy prop.kc2g.com
I’ll be checking this live MUFs website and DXHeat … courtesy dxheat.com
…before I jump in the car Wednesday to do my planned 10m CW activation.
