Un anno di DX - un articolo di Daily DX

Buongiorno Dxer di HRW. Ecco un analisi dell'anno appena trascorso dedicata al DX in HF. Un interessante disamina da parte di W1JR per Daily DX:

Special Edition – 2017 DXCC Year End Review – by Joe Reisert, W1JR –
January 9, 2018 2017 Overview:


DX propagation took a sharp decline in 2017 especially on the upper HF bands as we approach Solar Minimum. There were approximately 100 days with NO sunspots. In March ARRL deleted KH4 and KH7K but reinstated them several weeks later so we are still at 339 active entities. There was no known activity from any of the 10 most wanted entities on the Club Log DXCC Most Wanted List and only intermittent or short single operator activity from another 4 entities in the top 20. There were approximately 285 entities activated in 2017, about the same as in 2016 with over 275 on CW. As usual, there were many DXpeditions although not in the 20 most wanted entities. Probably the biggest news this year was the introduction of the FT8 weak signal digital mode introduced in July. More on that later…………………

-se volete leggere tutto, aprite il PDF allegato, anche se non masticate bene l'inglese si capisce tutto. Buona lettura!
