Slowly declining solar activity

Sunspot numbers (smoothed) are now about a third of their value at the last peak. Slowly, but surely, the solar activity is falling away. It will be some years to the next minimum (2019/2020?) and the next peak is expected to be poor or even non-existent. We wait and see.

Certainly the lower bands will become more important, although there is still propagation on the higher bands despite people going down the bands. I advocate WSPR or JT modes when the higher HF bands are quieter.

In years gone by I was surprised how useful 10m was with 10W SSB inter-G. In RSGB 10m contests at night I could always work stations on the south coast and Yorkshire despite just using a dipole. WSPR or JT modes should be far better.
