PI2NOS is active again (reported by PC5D)

From Jan PE1MFS I received the message that PI2NOS is active again.

From RSGB news (reported by PC5D)

On Monday 5 July the RSGB webinar Tonight at 8 will be about EMC. John M0JAV will be able to show you how to rate your station on UK regulations for EMF levels. These are part of Ofcom's new license terms. Tonight @ 8 Takes a break in August and then comes back with a great program for the fall. For more information about this and past webinars, visit

Radio weather (reported by PC5D)

Two sunspots whiten more powerfully than previously thought. The number of sunspots was reached 53 making it a lot larger than NOAA had predicted. The solar flux index is now also much higher at 95. On the 10 and 12 m bands, this has led to openings to Southeast Asia, the Caribbean and South America. Sporadically starting to slow down a bit as we enter July and this is probably not helped by the Kp index rising to four on Wednesday.

The big IT store at the University of Massachusetts continues. This means that there is currently no ionoprobe data on the website for foF2 charts. The measurements of the iono probe in Dourbes are still available. The maximum usable frequency of 3,000 km over a distance between 9 MHz at the end of the night to 18 MHz during the day. However, there are also times when the ionosphere does not allow proper measurements. equipped with Sporadic-E openings, we can't expect the MUF to get much further until the fall.

NOAA expects the solar flux index to drop back to 85. Earth magnetic conditions are expected to remain clear with the Kp index remaining at two to three.
The jet stream also appears to be strengthening again, favoring the chance of sporadic E. On Saturday morning, the better starting stations at 6 in FT8 were able to connect with Japan and Korea. HB0WR could be worked in Liechtenstein via a short skip

Our region was too far from the coast to take advantage of tropo. last Wednesday night at Tropo in GM4ODA in IO99IV in Shetland Islands to make a QSO over almost 700km on 10GHz with G4DBN IO93NR.
