#FT8 #10m and greyline enchanced sporadic E?

SFI:70 SN:16 A:5 K:1

Sunspot number increased today to 16! I expected some propagation but am always surprised by the signals. First station worked at my morning coffee break was RA1WY with excellent signals at the side of my HF5B beam.

OH propagation, notice the greyline
Is there something known like greyline enchanced sporadic E? I don't know, but probabely there is. It was definitely a large ES opening towards Finland today. And since most of the stations are in the greyline there I thought there has to be greyline enchanced sporadic E. My antenna is still pointing south, yet the OH stations are as strong as +18dB on FT8!!

After my lunchbreak I decided to leave it on 10m FT8 (what else could I do). I'm not able to remote control the direction of my beam. So it is left at the direction south.

At the afternoon coffeebreak there was time again to do make some remote calls, when I noticed I already received south africa just before local noon. These days the greyline is as early in the afternoon as my coffeebreak at the job. Lucky me! I could prove the enchanced greyline propagation, ES or not, is improving even as high as 28MHz. And indeed, the ZS stations came in very loud although it seems they didn't copy me. Then suddenly I see XT2BR (Burkina Faso) with loud signals even +2dB!! Is it possible.....yes it is, QSO made. Suddenly propagation is wide open to the south. Italy, France, Spain, Austria, Germany, Poland, England all coming in. Greyline is almost gone, but my coffeebreak is over...

Later that afternoon I got a message from another neighbour station PA4O Peter. He reported ZD7GWM (St.Helena island) with loud signals on 10. A few minutes later I received this screenshot. Certainly nice DX on 10! On PSK reporter I saw him as well with +3dB report from my station. Unfortunately, since I was on my job,  I had no time left to work him.

late afternoon after the greyline.
Monitoring FT8 today proves that it could be better for probing propagation. However PA0O who was still on WSPR 10m today spotted some interesting paths I didn't see with FT8. A combination between FT8/WSPR would be ideal!

If propagation will hold like this till the weekend or even improves, well in that case we don't have to worry about making some DX contacts.

It could be my reception but zooming in at my country I see a lot of stations active on 10m today, it surprised me actually! Like always I seem to receive far more compared to others in my country. I can imagine that if you're living in a city or a large village. Many radioamateurs have a lot of QRM from all kind of appliances these days.


  1. Hi Bas

    The 6th of Dec was a pretty good day for FT8 on 28 MHz, much better than the last week. This is what I heard... From PA, I heard PA4O, PD1DL, PA3DAT, PA7ZZ, PD4KK, PD0H.

    Very interesting to see VK2 spotted on WSPR in PA! WSPR is definitely more sensitive but there are not enough people QRV on 10m.

  2. Hello John, tnx for the comment. It was indeed a good day on 10. You did remarkable wll on 10m I see. I'm curious what today will give us. 73, Bas

  3. Hallo Bas, 10 meter blijft leuk, ook nu in het minimum. Mooie DX op 10, prachtig. Die hoor je niet elke dag. 73 Paul PAØK

    1. Zeker Paul, het was een goede dag vor 10m. Had verwacht jou ook nog wel te zien. 73, Bas

  4. Interesting stuff! Curiously, I was getting lots of midnight spots on 14MHz WSPR from Scandinavia 06/07 December, so something seems to have been happening in that area...

    1. Hello John, I did read your blog on that matter. Personally I thought the ES was enchanced by the greyline. I had a similair thing when we got in the greyline late afternoon! The mystery of ionisation....73, Bas


Thanks for your comment. Bedankt voor je reactie. 73, Bas
