Hi MF, I just sent a single WSPR block and got the following results from distances above 300km. This is typical for the winter season. 73, Stefan 27 spots: Timestamp Call MHz SNR Drift Grid Pwr Repo
Hello Stefan. Sorry but I do not understand. Can you explain to us scientifically why you said that there is a difference enter winter and summer for day time groundwave mode of propagation ? Also, a
Hi, I also recognised that ther's sometimes a kind of hop to LA and OH during daytime. ufb Stefan 73 Vinny Am 04.12.2016 11:52, schrieb DK7FC: Hi MF, I just sent a single WSPR block and got the follo
Hi Andy, Stefan, daytime propagation on VLF/LF beyond a few100 km (and likely also on MF) is dominated by ionospheric reflections, rather than groundwave. Despite lower solar elevation on winter days
Hi Jim, Anomaly or not, fact is that for example EA5DOM has been decodable regularly by a few stations above 1000km in daytime during the last weeks. This is reproducable in winter. In summer, there
Hello Stefan, In the NDB band, I could hear stations from Italy, Austria, Poland and Romania, which are normally only there after the sun has set. I gather that the sun is no longer able to build up
Hi Roelof, Am 04.12.2016 16:43, schrieb Roelof Bakker: I gather that the sun is no longer able to build up a decent D-layer at daytime at this time of the year. Yes, that's exactly what i'm thinking
Hi Folks Just to recall the article written by Alan Melia, G3NYK, which describes the LF/MF propagation mechanisms and also this daylight skywave propagation http://www.472khz.org/pages/technical-top
Hello Jim, The station is NDB YQ on 305 kHz. Today propagation was even better than yesterday and provided aural copy of NDB YQ-305, Churchil, CAN MB and LT-305, Alert, CAN NU, 4014 km. See the attac
This type of propagation has been exploited on this side of the pond in the past already for 2x QSOs: http://njdtechnologies.net/a-midday-surprise-jt9-wg2xjm-wg2xiq/ 73 Eric NO3M / WG2XJM I just sent
