Es DX

As mentioned yesterday, Es DX can be spectacular at times. I am not a great believer that these really long paths are multi-hop Es. Far more likely are some kind of chordal-hop DX paths.

At this time of year Es is best in the southern hemisphere in places like South America, South Africa, Australia and New Zealand. As well as the usual 1 and 2-hop Es keep a watchful eye out for real DX.

Last season, JT65 was useful on 6m. FT8 is not as good on weak signals, so I am not sure what mode to try next summer here in Europe.  I have had little success on 6m WSPR.

Last summer I copied loads of continents on 6m JT65 with just a simple vertical omni antenna by Es. There was one morning when a whole stack of JAs were copied "over the pole".  No wonder they call this the magic band. At any point in the solar cycle it can surprise us. Often there is just white noise, then something special appears.
