6 Meter Sporadic E Propagation

September 01, 2021

Sporadic E - Sporatic E is an unusual form of radio propagation using characteristics of the Earths Ionosphere. But is it really the same as much more intense summertime Sporadic-E.

Sporadic E Propagation The Heart Of 6 Meters K5nd

June 27th 2021 Sporadic-E propagation on six meter amateur radio band.

6 meter sporadic e propagation. Sporadic E propagation is probably the most interesting and exciting forms of signal enhancement for the keen VHF operator or anyone interested in the 28Mhz 10m 50MHz 6m and 144MHz 2m amateur bands. 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. The band Ive been on 6 meters is just below the bottom of the old VHF TV Channel 2.

You can help generate this page. A few days ago I had a contact with a guy in Spain on 6m. In the southern hemisphere sporadic E propagation is most common from November through early February.

LIGHTNING ACTIVITY- Sometimes appears to correlate with Es and often NOT. 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. SIX METER PROPAGATION MODES Mode Times Equipment Range Line of sight Any time 10W and small antenna 0-30 miles Sporadic E Sporadic but typical seasonal times 10W and small antenna 600 to -1500 miles single hop.

It is great for upper HF and lowband VHF contacts to distances of about 200 to 1500 miles. A group of Hams living on the east coast of Vancouver Island and the west coast mainland hold a 6-metre net at 1100 am on Saturday mornings. Sporadic-E is the most common workhorse for six-meter operators.

6 Meter Es Sporadic-E Propagation doesnt appear to be tied to a solar cycle South Pasadena ARC - K9LA - July 2021 19. Get customized propagation alerts by-E-Mail. In the southern hemisphere sporadic E propagation is most common from November through early February.

Received using Apache Labs Anan 8000DLE using 290 foot loop antenna feed with 600 Oh. 2500 miles double hop or multi hop F2 Depends on SFI A and K solar indexes 10W and small antenna at max sunspots up to 10000 miles. 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.

K1SIXs 6M SPORADIC E INFORMATION PAGE. Sporadic E clouds are usually fairly small in size but larger clouds or multiple clouds often form during substantial openings. Sporadic E propagation is probably the most unpredictable.

William Hepburns Worldwide Tropospheric Ducting Forecast Site. Whereas most forms of skywave propagation use the normal and cyclic ionization properties of the ionospheres F region to refract or bend radio signals back toward the Earths surface Sporadic E propagation bounces signals off. HamSCIs K1YOW has been investigating and says weather plays a big role.

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. Keen sporadic-E watchers will monitor the 10 metre band taking note of the locations of stations heard knowing that the shorter the skip the stronger the E-layer ionization and the greater the chance of propagation extending to the VHF bands 6 4 and 2 metres. The rest of information is useless and it doesnt interest anybody.

Es is somewhat independent of the normal 11 year 22 year Solar Cycles that affect F layer propagation. The net is found at 50150 MHz upper side band. The best bands to work Es are in the range of 14 MHz to 70 MHz.

Tropo forecast for Europe. November 2015 Same shot a month later with front yard cleaned up. 10 miles away listeners may hear nothing because Sporadic E propagation isnt affecting them.

Sporadic E provides strong signals even with low power. Increase in E-layer propagation on 6 meters. 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.

Thats similar to while different in important ways from watching Channel 2 TV from Spain and I get a kick out of the novelty. SO for 6 meters if you want to grab the ring you need to be there 247. 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.

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.

Alas probably not going to happen but we still need to watch for those openings. Send formated DX spots indicating clearly both locators and the type or propagation. Thunderstorms Causing Sporadic E - A Case For Thunderstorms Causing Sporadic E on 6 Meters.

New Hampshire Foliage Tracker. The 6-meter band shares many characteristics with the neighboring 8-meter band but it is somewhat higher in frequency. Real-time sporadic-E cloud location and MUF map.

Worldwide 6 m beacons GOES X-ray Flux 1 minute data. 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 It comes back. Make sure your locator is OK in the callbook.
