Area DXers 06/03/1911 September and March are two months of the year is equinox and offer the best conditions for reception of distant radio stations . At this time of year you can hear the opposite hemisphere stations, the other side of Ecuador, in short waves of higher frequencies.
Already at the beginning of this month some radio organizations, for example, Russia, France and other countries, change some of the frequencies used to transmit time and pass on new frequencies, higher in the Northern Hemisphere and more low in the Southern Hemisphere. Seasonal changes are related to the arrival of spring and autumn, respectively.
last Sunday in March, which this year falls on 27th of this month, will be the biggest change in broadcast radio and passed the winter time to summer time (in the northern hemisphere) summer and the winter (Southern Hemisphere). The period designated by the symbols "B 10" is replaced by the term "A 11."
will be changed most of the frequencies, as well as programming schedules. The latter is the purpose of providing listeners, who also handles his move clock to move to daylight saving time in the Northern Hemisphere and winter in the Southern Hemisphere.
In the days immediately before and immediately after the equinox there is the possibility that certain days are rarely heard tune stations and situated to the southwest of the listeners in the Northern Hemisphere and to the northeast in the Southern Hemisphere. This can occur within hours of the morning, local time. In Europe, for example, before and after sunrise and be heard, but only on certain days, purveyors of Latin America rarely heard. Possibly
tuning on certain days is not impeded by disruptions in the Earth's magnetic field caused by increased solar activity.
usually in late March and early April loud explosions occur on the outside of the solar corona. This phenomenon is dangerous as the ejected plasma flow is directed toward us. Nor is it to disparage the massive solar wind could also hinder the normal broadcast airwaves.
Still, it is expected that in most of the month there is a better line of distant radio stations that emit at higher frequencies.
Listeners must have adequate antennas and receivers, and adjusting for the night and at dawn on tropical band frequencies of 60 meters on shortwave.
If you also saw industrial interference minimized, you could tune in, for example, signals from Brazil, Peru and other South American countries. Incidentally, this situation will continue until mid May.
Forecasts for the bands of 19 and 22 meters are a better reception in the clear part of the day, ie day, although this could hardly occur also at lower frequencies of the bands of 25 and 31 meters.
Short waves in the bands of 41 and 49 meters, as well as medium and long waves will be accessible only at dusk and at night.
inadequate conditions are expected to reception in the bands 75, 90 and 120 meters shortwave. In northern latitudes there will be opportunities to practice yet DX TV and VHF / FM, except in areas where it occurs the phenomenon of aurora borealis.
