Partial solar eclipse in Sweden

The solar eclipse at my QTH on March 20, 2015 was 90 % partial. I used my bird spotting tube to project the sun disc on a piece of a cardboard.

How to check SMFF activity

Hunting (visiting) Swedish nature reserves and national parks for worked nature reserve SMFF diplomas or just for fun is popular among Swedish hams. This is administrated by SK6AW SMFF.

On the SK6AW SMFF page is a link to "Senast aktiva" (latest active). This is of great help to see where and when and on wich band/frequency SMFF stations recently have been active. The photo below shows recent SMFF activity on my mobile phone as it was on March 13, 2014 13:18 UTC.

Another easy way to be informed about SMFF activity is by listening to an Internet SDR radio while driving. In the video clip below I am listening to a SDR radio in Holland. This is when I am near a nature reserve called Torsmyran SMFF-2331 in Nordmaling in northern Sweden.

Some of my nature reserve visits in 2014 in northern Sweden are described (photos and videos) here.

It´s cold outside

January 23, 2015: The photo shows a balanced feeder starting point to a low hanging G5RV wire antenna. At the left side of the little storage house is clamped a 6.5 m mast with an inverted dipole for 7 MHz.

It´s cold outside so I prefer stay indoors. The temperature is -20 C. It dropped down to -30 C a few days ago. We have a lot of snow here in Boden (KP05vs), ca. 1 m. The Sun is up now for 5 1/2 hours, today 07:58 - 13:31 UTC.

I tried to call CQ with the Elecraft KX3 (10 W output) on the 7 and 14 MHz bands with no luck. On 21 MHz the noise was low and my first CQ was heard by several stations in the Reverse Beacon Network. Henry, HB9APJ near Zurich answered my CQ. He used a 3 el yagi and I the inverted 7 MHz dipole. We both exchanged 579 reports. Mni tnx Henry!

Christmas Aurora

December 24 2014 20:30 UTC - QTH Boden, Sweden Loc KP05vs - Outdoor temp -25 C (-13 F)

The Russian TV-carrier on 49.750.00 MHz can also be used (in Europe) to monitor Es and meteor activity. When listening for meteor "pings" the receiving frequency in CW mode should be set to 49.750.00 MHz or in USB mode 49.749.50 MHz. "Pings" and sometimes longer lasting "pings" are always heard, even when there are no well-known meteor showers happening.

A nice view of the Big Dipper´s seven stars behind the Aurora cloud. Close to Mizar, the second star from below, is another star. Its name is Alcor and it is one light-year beyond Mizar. Resolving them is used in a traditional sight of test. Right click on the photo to open it in a new tab and the left click on the photo to magnify it (1600x1600 pixels). Now it is easy to see the star Alcor.

A small group of stars can be seen in the photo. It is the star cluster named Pleiades. This cluster is a smaller version of the Great Dipper. By magnifying the photo you will get a very nice view of the Pleiades.

Camera Sony NEX-6 in auto mode (green). Typical exposure time was ca. 3 seconds automatically set by camera for photos above. A tripod is needed!
