More active amateur radio stations challenging the poor HF propagation conditions…

Si amigos, thousands of amateur radio stations from all around the world are expected to be active during the CQ Worldwide CW Contest [0000Z, Nov 24 to 2400Z, Nov 25]… including several well experienced teams of operators from Cuba, that will be using the T4 , tango four prefix, preserved here for special events stations…
Due to the expected bands conditions my forecast is that activity will be concentrated on the 20, 40 and 80 meters bands, with less contacts possible on 15 and 10 meters. For those stations capable of operating on 160 meters from nice low radio ambient noise locations, where the large size antennas required for that band can be installed the propagation conditions are expected to be better than during last year’s contest.
Stations located inside the areas covered by TEP, Trans Equatorial Propagation, events will be able to add many points and multipliers… For example Cuban contest stations will be scanning 10 meters to pick up signals from Argentina, Uruguay, Paraguay and Chile. Contest operators that use the 10 meters band have learned how to monitor the many automatic beacons operating on the segment from 28 point two to 28 point three megaHertz.
This is Radio Havana Cuba , the name of the show is Dxers Unlimited and here is our next radio hobby related information.
For those of us that live North of the Equator, one of the most interesting effects of winter propagation is a consequence of the contraction of the ionosphere… that causes a decrease at night of the maximum usable frequency for any given path after local sunset…One can witness the maximum usable frequency nose diving below even the seven megaHertz or 40 meters amateur band, and on some occasions the ionograms will show that the lower layer of the ionosphere will not support communications on frequencies above 6 megaHertz.
Yes , let me warn you that at times during solar minimum years, during the winter season the maximum usable frequency at night may drop even below the six megaHertz band amigos !!!
See you all at the middle of the week edition of Dxers Unlimited, that will be on the air just after the half hour news service.
