Solar cycle

As we are now on the downward slope of the solar cycle it’s worth checking the latest solar data.

Declining sunspot numbers and solar flux

This is just a reminder that the downwards slope of the solar cycle is usually much gentler than the climb to the next maximum. 

This means the higher HF bands remain good for quite a while after the maximum. 

Just a reminder, I have worked South America right at the solar minimum on QRP (10W) 10m SSB with simple wire antennas. Never give up!

The MUF is often higher on N-S paths. Occasionally you get Es linking with F2 nearer the equator.
