[CCF] Auroraa luvassa

[Kim Östman]

Voi voi, CQWW SSB -kilpailu tulossa viikonloppuna. 

Kohta laitan Facebookin Revontulikyttääjät-ryhmään kuuman vinkin, että mikäli haluatte aina tietää milloin on nähtävillä parhaat reposet, tsekatkaa radioamatöörien kontestikalenteri...!!

Rationale: G1 (Minor) geomagnetic storm conditions are likely late on day two (24 Oct) and increasing to G2 (moderate) conditions on day three (25 Oct) due to the anticipated onset of a positive polarity CH HSS.
