There had been much anticipation of a decent tropo opening around the 23rd September with a large, stable area of high pressure forming over north west Europe. In the end it turned into something that people will remember for a long time, with some fabulous contacts made. I can’t wait to see reports from the likes of GI4SNA, OM2VL, S51ZO, and others, which I’m sure will be amazing!
Here’s my own story, with apologies for the length…
The Hepburn forecast map was looking good with a nice yellow/orange area predicting long-distance potential:

On the morning of 22nd September things started to look promising, with a few reasonable contacts over 800km to the east and south – not huge signals, but it was something:

Later that evening and into the morning of the 23rd September a few more signals appeared:
22/09/2013 22:32 DG0VOGÂ Â Â Â Â Â Â Â Â JO60QUÂ 51Â Â Â Â Â Â 519Â Â Â Â Â 1496km

23/09/2013 09:18 DF1CFÂ Â Â Â Â Â Â Â Â Â JN57FPÂ 57Â Â Â Â Â Â 52Â Â Â Â Â Â 1417km
Once again the signals were not too strong, but the distances were very good: This usually indicates there’s a good high-level (mid-tropospheric) duct somewhere along the path, but it is almost certainly extended at one or both ends by a local low-level inversion. There was certainly one at my end of the path, if the thick fog here was anything to go by.
After the QSO with DF1CF @09:18z things started to go downhill very rapidly as the local inversion lifted, to the point where the band seemed absolutely dead more-or-less everywhere. This was disappointing, because it showed that few, if any, people were able to directly access the mid-tropospheric duct at this time – probably because it was at too high an altitude (indications are it was then >1400m above sea level). Over time there was no doubt the high-level duct would descend, as it always does, but of course the high pressure system itself would also move. There was plenty of nail-biting at ‘3KD, hoping the duct would come directly into range at some point!
Luckily, this is where well-sited beacons show how useful they are: HB9HB (JN37qf/1226km) is located at 1395m asl and was a constant signal even when everything else had faded, confirming the duct was still present. Indeed it grew in strength, thus raising hopes…
Then, at around 12z, the first “properly ducted” signal suddenly appeared, from OE2XRM (JN67nt/1589km)! It took a few calls to attract his attention through the instant pile-up, but a nice QSO resulted. I didn’t have the audio recorder running at the time, but made this recording just a few minutes later:
Soon after, more and more signals started to appear from a similar direction, characterised by good signal strengths disturbed by very deep and rapid fading. The distances were great, varying from 800 to over 1500km:

I even had a QSO with F5SE/P (JN19xh/905km) on 432MHz – but more about my 70cm exploits later…
At 16:35z, I glimpsed a comment from Pista, HA1FV (JN87jj/1858km) in the ON4KST chat that he could hear me – but I already knew because, to my amazement, I could hear him calling! The signal was quite weak but an easy QSO resulted, most certainly via tropo from the duration and “sound” of the transmission – unfortunately I didn’t have the audio being recorded at the time, so no clip.
Some minutes later I was still getting over the shock of working Pista, and struggling to receive a French station who’d faded into the noise, when I heard “S51ZO S51ZO?” being sent on CW. I had half a mind that it was a wind-up, but went on to work Joze, S51ZO (JN86dr/1856km) very easily – I was amazed when he confirmed the QSO later in the KST chat! This time I remembered to turn the audio recorder on right at the end of the contact, so got a brief clip that indicates how good a signal it was:
Conditions were getting better all the time and I was very pleased, shortly after S51ZO, to work Frank OE3FVU (JN78ve/1754km). Signals were slightly down during our contact, although it was easy enough, but I made this recording of Frank very soon after:
More nice contacts followed, including many to the south of Germany and Austria:

Did you notice the two 70cms contacts in the log, with DL5MAE (JN58vf/1480km) and OE5XBL (JN68pc/1587km), and earlier with F5SE/P? The FT857d I use can run about 20 watts on 432MHz but I don’t have an antenna for 70cm. However, I know from past experience that 2m Tonna antennas, such as my 11el, are not too bad a match on 70cm – So these QSOs were made with the barefoot FT857d into the 11el 2m antenna! It’s a slightly complicated process to switch bands, because I have to disable the 2m masthead preamp and apply an offset to the antenna azimuth because the pattern is skewed on 70cm, but it worked 😀 Here’s the audio from the ‘MAE and ‘XBL QSOs with us QSYing from 2m up to 70cm:
At around 19:15z I was tuning around the band and came across a CW signal that sounded a bit “DX-ey”. I was astonished to hear, very clearly, “OM2VL OM2VL OM2VL”, but was so excited I a) immediately forget his call, and b) initially forgot to switch the rig from SSB to CW. It was a brilliant QSO with Laci, OM2VL (JN87wv/1909km), but the chaos is adequately heard in the following clip 😀 About ten minutes later I could hear Laci very clearly on SSB, and on telling him that in the KST chat he asked me to call again for a very nice SSB QSO:
This was the peak of the opening for me and conditions very slowly started to drop off, although a number of great contacts followed for the rest of the evening through to the following morning, including a fantastic CW QSO with Zvonko, 9A1CAL (JN86dm/1867km).
I heard a little later from Moma, YU1EV (KN04cn/2246km), that he had heard me 539 during my QSO with 9A1CAL – it’s such a shame I didn’t hear him call!
