May 20. 2003 - And another big one... | Please send your comments/reports/log-sheets/audios to DK5YA

Again MUF was rising high pretty fast in the morning and at 11:03 UT the band was open from CT to 9H1. That one lasted for some 40 minutes. MUF reached 144 MHz again at 15:42 UT when EA7 and EA5 was into DL and a few minutes later CT into OE and OK. But then, surprise, suddenly EB8BTV reached the band working DL, OK, HB9 and OE. Some cracked the 3.000 kilometers, OK1TEH made the ODX with 3567 km! The cloud was moving west slowly bringing PA0, ON and F into the game to EA7 and EA4/5 and at 16:51 UT EA8 was 59+++ into G and later into F too. Now we saw EA7 into EI and GW and suddenly CT again into Italy while EA8 was heard in Ireland. Wow, ping pong across Western Europe :-).
And the cloud came back to the east, EB8BTV was very busy working OK, DL (yes, me too...), heard in HA. At that time (17:00-17:40 UT) MUF reached almost 220 MHZ cause F was working into CT on a QRB below 800 km! EA9  came to 144 while CT was working into DL, PA0, I, S5, 9A and F made 7X. Great deal today!
Involved DXCC: 9H1, CT, CT3, EA, EA8, EA9, F, G, GW, HA, EI, PA0, ON, LX, DL, OK, OM, HB9, HA, OE, S5, 7X, 9A, I.

NC-No contact (QSO wasn't complete)
I was one of the lucky guys, who was on the right place at the right moment :0). I was driving home after work, when I noticed several european FM stations on my car radio.
I rushed home, and I pick the Es opening right at start
on my locator (IM68da)!As you can see, the opening wasn't continous, but with 3 periods instead: 1700-1723, 1740-1746 and 1751-1809z. Signals were strong most of the time, but ocasionaly weak. There was also several deep QSB moments who made me lost  the contact with several stations before finishing the QSO :o( Even so, this was my best Es, ever!!! In total I have worked 2 new DXCC (HB9+OK) and 15 new Grid squares!!!I just hope this is the first long opening of many more to come! Good luck to you, and to all your web site viewers.

On 20 May 2003 I was on my Mobile/portable station at IM58JR, at the time I only knew I was at IM58. Now I can say that I was at IM58JR. I start with EA8 stations comming 59++, then when I start to listen for Europe, (please follow the map) I heard east France, then central and then Oest France . then I heard 2 or 3 stations from DL land. Heard CT3H. I also made some contacts to EA8 land on UHF.

It was an opening with ups and downs here, nothing stable at all: I heard my first sig with EA1AK/7 at s1 only but just two minutes later it looked like someone had pulled a switch: s9+++ for some minutes. Many more EA7s from IM66, IM86 were heard here (also on FM but they wouldn't answer my calls in Spanish or English) but I was mainly looking for stations in missing grids (IM77, IM79). Sadly EB8BTV was not audible at all.

I start monitoring 144,300 at 14:00 UTC. At 16:00 EA1AK/7 came out of noise for 10 Minutes S9. Heard and worked only EA1AK. Strong winds here, signal with fading. Very short ES for me. My RIG: 150W 9ele Tonna QTH: 950m asl.

- QRL until 17.00z (normally)
- 16.30z got Sporadic-E warning on my mobile phone from DXRobot [read here how to get spots on your cellphone]
- 16.31z logged into dx-cluster via WAP
- 16.32 -> 17.00z observing cluster reports while still working (fast...hi)
- 17.20z still customers at QRL (i want to go... please!)
- 17.25z end of QRL - finally
- 17.26z still ES on 2m, I am hopeful !
- 17.30z I am in my car, tune the IC-706MK2G on 144.320MHz
- 17.40z I am on the motorway to home (still 40km to go)
- 17.45z till 18.00 while driving on the very left lane at 200km/h I copy EB8BTV wid 41qsb on my 1/4 wave mobile antenna he must be vy strong on a normal rig....I am still hopeful and thinking to myself "yes, you will get him when youre at home"
- 18.05z I AM AT HOME ! oops...never been so quick before
- 18.06z my rig is on, BUT: no EB8BTV, just hrd CT1EXR IM57 fading out on 144.305
- 18.10z ES seems to be over here
- 18.11z the next opening starts: a bottle of beer, relaxing
The conclusion:
1) does this hobby still drives you as crazy as me?
2) if you want to have a rare ES opening on 2m -> go to work longer than usual. Murphy will do the rest!

was monitoring the .320 for more than 2 hours and failed, at least. Signals were too weak in JO50. The last time I heard EA8 I was an SWL... Caught EA4CTF instead fm IM89 59/59. Not bad.

DL2ARD, JO60ar
Came to the shack at 16.45 UT and thought I was to late as usual. Heard EB8BTV at 17:30 UT max. S3, no way to catch him. Later EA8BPX was calling CQ on .300, split .370, worked him easily with 55/55. Same time EB8BTV disappeared on .320. 1 QSO, 1 DXCC, 1 square. Better than nothing.

At 16.15ut HB9FAP calls me up for E's warning! I went to the station and in 2 hours been standby I worked only
CT1EAT. I heard many times EB8BTV but to weak to work, but not one other station, nothing. Very frustration, when being activ, hearing all around you station working EA8 and yourself can't participate. All in all 1 QSO and 1 new loc.

Wow, it needed more than 20 years of my amateur radio activity on 2m to catch EA8 finally (do you feel with me?)!
The evening startet first very boring with hearing all other countries around HB9 working something via Sporadic-E (a fully normal situation as every year btw.). Even when I saw the first announcement of EB8BTV in the cluster I never
thought the path will reach especially my QTH, you know! t was very interesting to watch DL's and OK's working Fernando, but still not an only signal over here so far - even no EA7's or CT's...hmmm.
All of a sudden I saw an announcement of an HB3-station in JN47 working Fernando and since then I didn't move the  VFO anymore and stayed tuned on 144.320 all the time with a lot of hope.
Finally at abt. 17.24UTC, EB8BTV came out of the noise CQ-ing. His signal sounded a kind like distorted but maybe that's normal with these distances. During the contact I remembered my ready tape recorder finally to start and
got about 5 min. of temporary very strong signals (later up to 58). I will send the audio file later to Udo as well.
After our contact, EA8TJ came back on the same QRG for my 2nd contact with EA8. Later on, EB8BTV CQ-ed anew and EA8TJ moved 20 up.  A little later I managed in a short normal openig to work EA4LU. Heard also a
CT station but afterwards the band closed again.
I think the sommer condx could go on like that, you agree?

Today was a bit of a frustration, as the Es into EA remained just to the east of me most of the opening. Worse was the EB8..... He was worked all over Europe, but I never copied anything from him. However, BTV must have had the time of his life with such a tremendous double hop opening!

Ionogram from El Arenosillo/Huelva, southern Spain at 16.00 UT May 20. f0Es was close to 10 MHz that time. This leads to the conclusion that we had NO double hop Es that day but a mix of tropo and Es that brought EA8 into middle Europe.

Hi All,

Actually its just a little more predictable than you think. Its within the scope of most stations to find there own backscatter  "echo" point(s). The opening on the 20th May from here (JO01gn) revealed 2 zones at 1400km and 3000km, a little short for most of the time to EA7/CT and too long to EA8. (This can vary dramatically with elevation but  thats another story). As Graham F5VHX suggests, there was probably tropo at the EA8 end but I believe this only extends the virtual Es path by k1/k2, the ratio of the relative refractive indexes. Its unlikely that any real reflection occurs on the sea/land as the loss introduced would be very high at these wavelengths (can be quantified). Its not unusual to hear stations at the intermediate skip distance, this unfortunately gives the illusion that the signal has returned to earth somewhere.....

Anyway, that remains academic, whats more important is finding if the band is "open" and to where. Being pre-warned means being well-armed to take maximum advantage as the band suddenly opens. To detect your own BS echo does not require any special kit other than being able to fast switch between TX and RX. Invariably, you do not need high power either, 100W is sufficient on "good" days, on really good days you can hear your return, on exceptionally good days there is actually stations to work.....

A solid-state switch is relatively easy to implement (see the SM5BSZ pages). You need a means of generating a short "keying" tone or a gating pulse, in the order of 100 microseconds (10kHz), thats rather dependent on what range resolution  you want to achieve and what your system will support. The shorter the better as Es is very range critical.
The amp usually has to be keyed live using electronic bias changeover. (At 300m/us *2 you calculate the necessary delay times, I use a sound card and Spectrum Lab, but this may cause problems with the latest modern rigs due to inbuilt TX/RX delay mechanisms).

You can process the received return either directly on a scope triggered from your TX pulse or run the output into a sound card and timer. No AGC on RX. This is not rocket science and this method has been used for plenty of
years here, mainly for F2 on 6m. There was a full description in QST many years ago (W5FF was the author I believe), I am sure there is a copy somewhere on the web archives. If you intend to go down this road I would suggest quantifying your RX system first, that is the delay time through your RX from antenna to audio output. Modern DSP radios screw up totally in this department as do noise blankers that are "active" all the time (i.e. un-modified FT1000's etc).

BTW there are at least 7 recorded Es incidents of OK1 to EA8 since 1982 and no doubt a lot more, this particular path is relatively common. Finally, to work Es succesfully, there is absolutely no substitute for being behind the radio and your finger on the dial....
