My antennas will be down over the next days. The vertical rotator is stuck since the big storm (gales to over 160km/h) on 28 October 2013 and the horizontal rotator seems a bit "ill" as well.

Throughout the last days I have viewed through many pages on this site. A lot of mistakes are corrected now. I do not think I found all ...

Since some months now, me and my son Michael added some RC Flying to "waste" some time with. We have built and flown with quadrocopters. We crashed them often and have rebuilt them. We have learned a lot on flight controllers programmed in C++ and Arduino. Things that work on earth do not necessarily work in the air... Amateur Radio experience helps a lot. So, I have added - a still empty - page in the hope the one or the other project may be interesting for you dear readers. Ge here: http://www.df9cy.de/rcflight/rcflight.htm

During this years' first BBQ at the local observatory, I took some shots of our sun. A number of tiny sunspots are visible (I count more than 20 ...) showing the sun's activity, which is high in this solar cycle; but low compared to previous cycles. Go HERE for more images.

Last night I realized a little late that a bright aurora display was going on. At a quarter to midnight I quickly drove down to our local beach a took a series of images. Go here to have a look at them.

On the evening of 30 October 2013 I realized that there was some Aurora (Polar Light) going on. I went out on the flat roof of my house, which is ideal for imaging such events down to the horizon. There I took a few photos, but there was not much time as the intensity was decreasing rapidly. HERE are a few more images for you. Next mornig I saw on the web, that I was able to catch the maximum intensity. From the amateur radio activity I could see as well that the main event has been very far in the north of Europe over central to northern Sweden.

Not much activity, because I am very busy with other things.

Also preparing a few new Technical articles for this site ....

Jul 13
50 MHz
12 July 2013 Not many signals heard, but I managed to work EA8DBM (IL18oh).
11 July 2013 Again Aurora and I could work several stations. But better was the St Helena Island beacon ZD7VC (IH74db) with a good signal for a longer period of time. I have a YouTube video of this event: ZD7VC at DF9CY

144 MHz
12 July 2013 ON6NL (JO21) was worked.
11 July 2013 On 2m I got some Aurora stations as well, but later the band opened via tropo and among the best were: F5XU (JN15), F8DBF (IN78), F9OE (IN78), M0BKL (IO80), F6HMQ (JN18), G7RAU (IO90) with all between 800 and 1300 km. I knew from the cluster of a EA1 being QRV. I could hear him talking, but too weak for a QSO.
8 July 2013 Many signals heard, best was EI3KD (IO51). Did not work anyone.

432 MHz
11 July 2013 My power is low enough, that I cannot work good DX, but coming from 2m I could copy well F6GNR (IN97) and F6HMQ (JN18). G7RAU (IO90) was worked and it was a new grid for both of us..
8 July 2013 Good tropo opening over the North Sea. Worked into Netherlands, England and caught LA/DK2BJ/p (JO37) for a new grid.

Jun 30
50 MHz
30 June 2013 Sporadic E to the North of Sweden and into Spain.
28 June 2013 An aurora opening produced strong signals and I contacted a few stations.
27 June 2013 The band was wide open to Italy and Greece, where I could catch a number of contacts. Later it turned to Spain and Portugal, but no humans could be heard. Almost all beacons were audible.
26 June 2013 VP2ETE was heard and the only worked was EA5/ON4CAU in his holiday resort.
24 June 2013 No Sporadic-E today, but some Aurora was going on. Before I left the house I only worked LA8AJA.
22 June 2013 QRV for only a short time when I worked EA9UG (JM75iv / Ceuta&Mellila)
21 June 2013 Official summer since this morning and rain ... Worked UN3M (LO61md) and heard UN3GX (MN83gd). SM2, SM3 and many OH were heard. The band was open for a long time at night and UN3M was audible still at local midnight.
20 June 2013 Worked Carribean HI3TEJ (FK92TL), PJ4NX (FK42UD). Heard were KP4EIT (FK68) with a big signal, FG4NN (FK96kk), VP2ETE (FK88).
19 June 2013 OH6NG/9 (KP27) was a new gridsquare
18 June 2013 Heard were A45XR (LL93gl) and the JX7SIX beacon. After being out of the house I was home late and only worked PA0RDY on tropo over 420km
17 June 2013 Open into many directions. TJ3SN was in for awhile, but to weak to try to call. Received VP2V/W9DR (FK78) very weak in the evening.
16 June 2013 Many contest stations audible. Only worked EI7M (IO51)
15 June 2013 Digital contact in JT9-1 with OZ1PIF
14 June 2013 Worked some stations from EA and CT.
09 June 2013 Only worked CT, but heard PY1RO, PP1CZ, PY2VA, LU5FF with big signals. Worked them before, so I did not call.
07 June 2013 Worked some stations. New: EI/ON4TA/p (IO44wc). In the evening Northern Europe came in.
03 June 2013 Only worked friend Yussi, OH5LK. Heard EA8SIX/b (IL18)


144 MHz
20 June 2013 Worked Es : 15:29UT 9H1CG (JM75FV Malta) and heard: I2SRM/8 (JN71jc). It has been a big opening, but not for us here.

May 29
50 MHz
29 May 2013 Open to Ukraine with big signals. DL2MWB worked tropo over 720km (!)
28 May 2013 Wide spread opening; only a few worked.
27 May 2013 Wide spread opening; only a few stations worked. Copied was 9J75FOC in South Africa with a good signal.
24 May 2013 Again SM, LA, OH
23 May 2013 Some Italian stations in the log
12 May 2013 Stations from Spain worked
01 May 2013 The first good Es opening on 6m direction SM, OH, LA; Strong Aurora coming up later.

144 MHz
01 May 2012 A few stations work on 2m via Aurora
