Last updated 13 October 2010.Autumn Tropo Opening 8 to 10 of October 2010!
During the weekend 8 - 10 of October we finally got a nice tropo opening on the microwave bands. I think we last have this kind of opening was December 2007? So waiting nearly 3 years I really enjoy this opening and it was very nice that it was during a weekend. I was also lucky because I was not booked for any other time consuming activity this weekend. During Saturday I with the family made a visit to the nice exhibition here in Stockholm regarding the "Chinas Terracotta army", some of the soldiers of that army have during this autumn invade one of our museum. Really nice exhibition but it was bigger to see in in Chine for 10 years ago. Well I got back from the exhibition in time for the evening radio operation. From Saturday evening at 17z to Sunday at 12z I was active, except for about 4 hour of sleep.
During the opening in December 2007 my station only had 23 and 3cm. Today I also have 13 and 9cm QRV and it was nice to make so many nice QSO on these bands. But it take a lot of time jumping around all the bands sometimes. But during this kind of opening it get easy because the signal was good so most of the band jumping went quick and easy. I worked several stations on all my four microwave bands and these stations was (yes several stations which I worked this weekend have my four band but we didn't try or didn't manage to get a QSO during the weekend) :

I hope to build my 6cm station during this winter and install it next summer. Still missing the preamp and the 10 MHz locked oscillator. When that is home I have some hours of building it... but that's another story.
The weekend started in the evening 8 of October with nice conds towards north, east and south with best DX to the south. To north I got a new square from SM0DFP on 9cm. We didn't try on the other bands. I also tried with OH2AXH on 9cm but conds was not good for SSB QSO at that time. To east LY2VA but conds was not good for 3cm at that time but we manage that during Sunday.
In the Saturday evening the big race started with good propagation to the same directions. It stated nice when I got my 122 square on 23cm by working SP5QAT in KO02. We have tried several times during NAC 23cm contest by using airplane scatter but never got it to work. Now finally the conds came and the QSO when complete. It was also nice conds to the north but most of the active stations have I already worked except SM4DHN which I now got on 13cm as a new square. The conds to the south was nice with many nice QSO but it slowly opened up to south west with all the German stations. In the end of the evening i came to Holland with some new squars on several bands.
Below is some tropo maps from William Hepburn's Tropospheric Ducting Forecasts for Saturday evening to Sunday morning:
2010-10-09 1800z | 2010-10-10 0000z | 2010-10-10 0600z |
I wake up early in the Sunday morning hoping for more good DX towards Germany and Holland. And it also started nice and quit soon it open to England when I listen for GB3MHL beacon. Shortly after that I got QSO with G3XDY on three bands and with a nice QSB on 9cm with 1100 km, that was great! Later I still copy the GB3MHL beacon but it was not possible to work any stations. At about 18z I closed the station after some attempts and checking of beacons. Even GB3MHL have then gone done into the white noise.
So in short I'm happy and glade that the autumn tropo openings still exist in this way. Hope it will soon be back. My station seems working nice even if I'm bit of a QRP station. Will build 6cm to next summer and if time also get some new stuff on 23/13cm with more power. Hope to get up to at least 100W at the antenna (today around 20-30W). The remote control of the station was working very nice during this opening as usally. I work most of my QSO from my home in Stockholm which is about 470 km by car from the radio site (6 hours driving). For this weekedn I only have some problems Saturday evening during about 10 minuets.
