Es in Europe

Things are getting better, but the Es is mostly in Eastern Europe.

See https://www.tvcomm.co.uk/g7izu/radio-propagation-maps/europe-sporadic-e/ .

European Es (Monday)

At the moment, Es in Europe is mainly in the east. Things can change quite quickly, so we will see how the day develops.

See https://www.tvcomm.co.uk/g7izu/radio-propagation-maps/europe-sporadic-e/

UPDATE 1836z: Things are looking more promising with widespread Es on 6m. Currently I am doing some 8m WSPR QRPP tests at 10mW with HC02 (1808km) in Portugal.  No spots all day.

European Es (Wednesday)

Early indications are that European Es is not as good as yesterday, but this can rapidly change. My current plans are 10m 500mW WSPR TX and 8m QRP FT8.

See https://www.tvcomm.co.uk/g7izu/radio-propagation-maps/europe-sporadic-e/ .

European Es today (Monday)

 At the start of today, I had great hopes for Es in Europe. Sadly, certainly at the moment, things are not looking too great.  Hopefully things will get better.

10m QRP WSPR (Sunday)

My 500mW W5OLF WSPR beacon on 10m has been on since before breakfast. It is now 0836z and, so far, 8 spots of me. There doesn't seem to be a great deal of Es around yet.

UPDATE 1438z:  31 spots of me so far today with the furthermost FR1GZ (9724km).

UPDATE 1846z: 50 spots of me today. More Es later.

European Es

It is now 0554z, so it is too early to tell how Es will be in Europe today. Assuming it is good, my plan is QRP 8m FT8 and 10m QRP WSPR TX. 

See https://www.tvcomm.co.uk/g7izu/radio-propagation-maps/europe-sporadic-e/ .

European Es

As Es propagation in Eastern Europe is looking good today, I am changing my plans. I was going to go on 10m FT8, but instead will try 8m FT8 and 10m WSPR.

See https://www.tvcomm.co.uk/g7izu/radio-propagation-maps/europe-sporadic-e/ .

F2 disturbed?

It is interesting that not a single signal has been spotted today from outside Europe on 10m FT8.  At the same time, I have spotted plenty from Europe on 10m FT8, presumably by Es propagation.

I am no expert on HF propagation, but it would seem F2 propagation is upset by poor by solar conditions, but not Es. If Es does suffer, the effect is much smaller.

D2UY in Angola has been a good indicator of propagation. Not seen this station today on 10m FT8.

European Es

In the last few days, I have found this site extremely useful. In a few seconds, I can get a "snapshot" picture of Es conditions in Europe. It gives me a good idea of what bands may prove useful. Of course, Es can change very quickly so this is not perfect, but it is a useful guide.

See https://www.tvcomm.co.uk/g7izu/radio-propagation-maps/europe-sporadic-e/ .

Es - promising?

A quick look at https://www.tvcomm.co.uk/g7izu/radio-propagation-maps/europe-sporadic-e/ suggests that European Es could be promising later. My current plan is 8m QRP FT8 and 10m 500mW WSPR TX, with 8m WSPR later. Things will be turned on later this morning.

If 8m is disappointing and few stations are active this Es season, I shall probably QSY to 10m FT8 next week. If the Es looks really good, I shall go on 8m again and on 4m FT8.

My 8m "experiment" was to find out how effective a very simple QRP station could be. For this lots of monitors are needed. Sadly, I think there are fewer people on than in the last Es season, at least so far. I was hoping 8m would be busy with WSPR and FT8 beacons from stations without a licence operating under ISM rules.

UPDATE 1446z:  Good Es today in central Europe!

European Es

Early indications suggest Es might be better today. 

See https://www.tvcomm.co.uk/g7izu/radio-propagation-maps/europe-sporadic-e/ .

My plan is to go on 8m FT8 (40.680 TX first, DF about 1950 Hz) again, as well as 10m WSPR QRP TX.

I hope to get some 8m spots again after a quiet spell!

Sporadic-E (Es)

So far, this has been a disappointing Es season. Things hopefully will change, but 8m has been very disappointing so far. By now, I was hoping for openings most days. 

UPDATE 1732z:  At the moment there seems to be a good Es opening in Eastern Europe. See https://www.tvcomm.co.uk/g7izu/radio-propagation-maps/europe-sporadic-e/ for G7IZU's excellent website.

Keeping an eye on Es in Europe

Following Hugh's (HC02) suggestion, I am now looking at this map of 8m Es in Europe.

See https://www.tvcomm.co.uk/g7izu/radio-propagation-maps/8m-40mhz-spot-band/

On the same site is this map showing live Es data for other bands. I get the feeling 8m Es could be promising later.

See https://www.tvcomm.co.uk/g7izu/radio-propagation-maps/europe-sporadic-e/ .

10m Es operation

As we approach the late spring and summer in the northern hemisphere we are entering the Es season. This usually means propagation out to about 1500km is possible on all modes, often with very strong signals. Es is good at any point of the solar cycle at this time of year.

Most days at this time of year 10m and the low VHF bands will open to somewhere. Not every day is good. Some days will be disappointing. Often antennas like CB whips work perfectly well. Usually a few watts is quite enough whatever the mode. 

The simplest antenna is just a low wire dipole, but my Homebase-10 may be useful. It is described on my website. It is essentially a wire halo. It could be scaled for other bands. It is low cost and makes a useful antenna for 10m.

Sporadic E (Es)

We are just entering the Es season in the northern hemisphere. DX out to about 1500km with low power is common on the lower VHF bands. The photo shows my V2000 omni in 2020. On 6m even QRP SSB is enough to work DX. 

The Es season has arrived

Judging by the results on 10m WSPR, the Es season has arrived. I must give 8m another go and 4m. As the season gets underway we can expect widespread openings from the UK to Europe and similar distances in North America. On 8m, the main issue will be too few people monitoring.

4m transverter

The photo shows my homebrew QRP 4m transverter. Late last year it was resurrected and copied some Es despite not having a 4m antenna. 

See https://sites.google.com/view/g3xbm4/home/vhfuhfmicrowaves/homebrew/4m-transverter .

Winter Es

Don't ask me why, as I do not know, but there is a small uptick in Es propagation in mid-winter. Do not be too surprised to copy Europeans on 10m and 6m, and possibly 4m too. I think Es can remain good until the end of January (ish). Remember that Es can occur at any time of year but is most common in the northern hemisphere in May, June and July. 

FT8 can be good for this as even very short openings are caught and FT8 is well monitored. As you know, Es signals can be very strong.

Es season well and truly over

Although Es can occur at any time, the late spring and early summer are the best times. Often bands up 4m can bring DX to up to 1500km, sometimes more. Rarely, Es occurs at 2m.

Today, for example I saw no evidence of Es propagation on 10m WSPR. The only stations spotting me were probably via F2 propagation or local. The nature of Es is it is sporadic, so the bands can suddenly come alive, which is why FT8 especially can be so useful.

When DX is not around, bands like 10m and 6m can be seriously under-used. This is a pity as they make good bands for club nets and local chats. Antennas are small and local noise is often much better than 160m or 80m, where antennas can be big.

10m FT8

At 0813z, my QRP 10m FT8 was turned on. The impression is that Es is patchy. It is now 0820z and, so far,  2 spots on TX and none on RX.

UPDATE 1315z:  59 stations spotted on 10m FT8 RX today.
