Content preview: I'm well aware propagation can be good even in mid summer, just as it is on 160m (where I have 297 DXCC worked so I've been around a while). QRN is the "season creator" here. Last year trans-Atlantic WSPR-2 decodes ceased in late March due to rising static. I'm seeing the same huge increase this March. I don't know what the band actually sounds like in Europe or what happens later in the spring/summer. But looking at lightning maps over the past few weeks I can make a good guess we have significantly higher static levels than you do.

Of course on the plus side we don't have DCF39. :) I rarely see it mentioned but isn't HGHA22 a nightmare too? It's often stronger than DCF39 over here. I have my fast, wide waterfall set so I can see both of them. They do make nice relative propagation indicators. I did see some evidence that DFCW can cut through the mess later into the season as I had full call sign copy on DF6NM and DF2JP in April 2017. 73, Paul N1BUG On 03/19/2018 12:39 PM, Alan Melia wrote: > Lots of people talk about a ''season'' but in propagation terms there isn't > one. you can get as good a propaga > tion in summer as in winter.
