Sporadic E at last, and polar Es too

Tah dah!

09/05/15 12:26-12:30 50MHz EA3NJ SSB 100W Hrd 59 MySigs 59 JN01OC Juan 1650km

At last! I have worked EA3N on 6m and I can take my long face off. Sporadic E worked. 9 May is not unusual.

There was a quite a bit of Es on 7 May but none of it heard here. It is very selective.

WSPR may not count as a QSO but this happened on 08/05/15:-

 2015-05-08 10:20  M1CDU  50.294462  -18  -2  IO95ej  +40  10.000  GM4FVM  IO85wu  60  37

Nice 2 way WSPR with OH7AI. I think that M1CDU, who you can see was around at the same time, was working into Scandinavia too, which was great.

Sporadic Es is easy to spot, usually between 08:00 and 14:00 and then again between 17:00 and 21:00.

You also get Es in the late evening and night to the North. this type of "Polar" Es comes in different types often associated with aurora. There is also "Thule"-type propagation in the Summer and I have often sat up on 50MHz late into the night hearing stations in the far North - Jan Mayen, Iceland and Greenland.

So this was  an interesting one:-
2015-05-08 22:28  GM4FVM  50.294484  -16  1  IO85wu  +37  5.012  LA5TFA  JP99kq  1852  1151 
 2015-05-08 22:24  LA5TFA  50.294504  +0  0  JP99kq  +37  5.012  GM4FVM  IO85wu  1852  1151 
 2015-05-08 22:18  GM4FVM  50.294484  -13  1  IO85wu  +37  5.012  LA5TFA  JP99kq  1852  1151 
 2015-05-08 22:12  LA5TFA  50.294504  +9  0  JP99kq  +37  5.012  GM4FVM  IO85wu  1852  1151 

LA5TFA is a good distance (1852km), and there is not much further to go as TFA is right in the North of Norway in Troms county. I really enjoy seeing TFA during these openings, though I have to say that WSPR makes the observations easier.

If only there were more VHF WSPR stations in polar regions and we could find out more about these strange modes of propagation. I guess there are not many people around, never mind VHF enthusiasts.

I spent a long time today with a fine needle resetting the BNC socket on my transverter. It looked too wide and maybe not making good contact with the pin. Didn't make any difference. Might have been a fault though. You can never be too careful.

Finally, I managed another square on 4m. On 09/05/15 at 14:30 I worked DG1VL. That was square JO61WE at 1174, worked on JTMS mode. It was all the nicer having come from a random CQ call. On the face of it this should add to the total of squares, but I have noticed that I have in the log from August last year - DF1VL in JO65WE (not unlike DG1VL in JO61WE). But JO65WE is not even in Germany and the callsign does not seem to exist. Looks like an error in the log. But isn't it funny - just noticing now DF1VL is wrong and replacing it with DG1VL with just one number different in the locator as well? Spooky ...


Did I say that I have still not worked any Sporadic E this season on 4m or 2m???
