6 Meter Sporadic E

Juli 19, 2021

Ive been able to pick up a few new DXCC entities and a whole bunch of 6 and 2 meter grids. Peaking around the solstices June and December this mode of propagation can provide contacts over a few hundred miles or a couple of thousand miles or more with a double-hop.

6 Meter Ham Band Activity Its Propagation Modes Explained

Multiple-hop sporadic E propagation allows intercontinental communications at distances of up to 10000 kilometres 6200 mi.

6 meter sporadic e. The 6 meter Summer Sporadic E season has been absolutely fantastic. For me this is as good a time as any to look back at the season that was while memories are fresh. On HF where refraction of signals by higher layers of the ionosphere cause longer distance propagation sporadic-E type conditions are often referred to as short skip.

Active Internet 50 MHz DX Clusters. It is also responsible for most of the long-distance 600km and greater contacts on the 6-meter band. Much like it was shown that North Atlantic transatlantic 6m propagation during the summer was made more possible by strategically placed weather storm systems it looks like a similar effect with very strong jet stream boundaries also affect sporadic-e like communications during the winter months.

It can appear at a location any time of the day or night and stay for a minute or 5 or 15 or 60 or 2 days. The 50 MHz signals reaching the E layer with a small angle of incidence will be deflected back towards the ground and will thus reach great distances from their point of origin. 6 Meter E Season Wrap-up for 2021 For all practical purposes my 6 meter sporadic E season is over.

Adapted from Arras et al 20101 Figure 1 Typical European sporadic E in August 2016. I think you have to bear in mind that 6m Sporadic E is primarily a summer phenomenon - that is not to say that there is no point tuning the band between September and late April but the openings are going to be a lot less frequent than they are in May and June and weaker when they happen. Sporadic-E also known as Es propagation is probably familiar to many low-band operators as the summertime short skip on 10 meters.

Sporadic E Propagation The Heart of 6 Meters. Figure 2 Statistical maps of sporadic E show that North American longitudes are less active on average compared to European longitudes. Thunderstorms Causing Sporadic E - A Case For Thunderstorms Causing Sporadic E on 6 Meters.

Putting a 6-meter yagi REALLY HIGH like over 100 feet will give you the maximum. Obviously Sporadic E is something you cannot count on. In Propagation and Radio Science Eric Nichols explains one possible mechanism is thunderstorms that are strong enough to break electrons free forming a cloud of free electrons.

Six meter DX information. Its about this time of year that we yearn for Sporadic E to come back with the same force it was here in May through July. Alas probably not going to happen but we still need to watch for those openings.

Amateur HAM radio operators have long used Sporadic E for long-range communications in the VHF band also known as the 2-meter and 6-meter bands by hams. On 6m you might get parts of four days too perhaps at the peak of activity during the two weeks around the Solstice at the end of June. The weekend of the ARRL Phone Sweepstakes contest in 2001 also coincided with the Leonids meteor shower and a massive 6 meter opening into the Pacific.

If you are a 10 metre band enthusiast you might get it four days in a row mind you not necessarily all day. Could similar weather events that allowed transat-lantic Es 6-meter communications also. Six-Meter Long Haul Sporadic E Es General Information Data and Links.

The real good Sporadic E conditions will start to die down generally by mid August. Sporadic-E is the most common workhorse for six-meter operators. This statistics were made using the data of the sporadic-E openings worked by myself from Jan1987 to Dec2002.

Yes there will be more openings from time to time. The 6-meter band shares many characteristics with the neighboring 8-meter band but it is somewhat higher in frequency. The E layer is present mainly during the day from dawn to dusk and is responsible for most of the 6 meter ham band activity.

WA2CWA Jul 14 2020. 6 Meters 2 Meters and a Meteor Shower My love of 10 meter sporadic-E propagation eventually led me to 6 meters where sporadic-E was hot and heavy during the summer months. Keen sporadic-E watchers will monitor the 10 metre band taking note of the locations of.

Climatology of Sporadic E can provide a probability that it will occur but the actual presence of sporadic E can only be determined through trial and error observations at the time. Upper-Level Lows and 6-Meter Sporadic E 1 I looked at the main causes of Sporadic-E Es why there were many more E sopenings in Europe than we see in North America and some of the causes that allowed 6-meter transatlantic communications. 10 miles away listeners may hear nothing because Sporadic E propagation isnt affecting them.

Sporadic E propagation is probably the most unpredictable. SO for 6 meters if you want to grab the ring you need to be there 247. For tropo on the other hand the higher the better.

But you better hurry. The distance between the transmitter and the receiver of the refracted signal is called the skip distance. ----- For sporadic E assuming flat land it appeared that the best compromise height was about 50-60 feet.

REGARDLESS OF SOLAR CONDITIONS Es remainstheBREAD AND BUTTER of the average 6M DXer. They should not be taken as an exact reference as I have missed many openings in those years. 50 MHz DX Cluster from OH 50 MHz DX.

In the southern hemisphere sporadic E propagation is most common from November through early February. Theres a strong argument for having antennas at different heights for different purposes. The question then arose.

Sporadic-E is a type of ionospheric E-layer reflection caused by small patches of. 6-Meter Sporadic E Using Amateur Radio to conduct real science in pursuit of a decades-old mystery. 6 meters was open between NJ and several other East coast areas to Japan and Asia several days ago.

K1SIX- SIX METER SPORADIC E INFORMATION. Chasing Grids 6 meters and 2 meters. What is Sporadic E.

However the likelihood of DX is low and that is my primary motivation.
