From January 28, 2021 to January 29 2021 the ISS send again pictures in Slow Scan Television. The images are always transmitted in Mode PD 120 on 145.800 MHz in Frequency Modulation. The following images were received with a 14 Element Yagi and decoded with MMSSTV software. More information about Amateur Radio on the ISS can be found on the ARISS website and the ARISS Blogspot. A nice Tracker could be find here.
Another milestone in my 48 years of Ham Radio: After WAC 432 MHz (1983) and WAC 144 MHz (2018), the WAC 1296 MHz arrived today. Of all these it was the easiest and all Continents were in the log after just 2 months of activity.
Nice surprise: The ARRL DXCC Challenge Medallion 2500 was in the mailbox today. Just a small round sticker, but so much time and work went into it. Challenge 2500 means an average of 250 DXCC Entities on each of the 10 Bands from 160m to 6m. The next and final level is 3000, but I’m out of business now. Unfortunately it is more difficult nowadays to get the confirmation for a QSO than to make the contact itself. Not to mention the cost of requesting QSL cards or LotW confirmations. Now it has a dignified place on the wall and will remind me of so many nice contacts.
The Perseids come around once a year in mid-August, when the Earth passes through a trail of comet dust on its way around the sun. The dust burns up in the Earth’s atmosphere and ionizes the E-layer. The Perseids are caused by debris from comet 109P / Swift-Tuttle, which loops around the sun on a 133-year orbit.
This year they should peak on Wednesday, Aug. 12 between 0800 and 2100 UTC. The Perseids typically deliver up to 110 meteors per hour at their peak. According to scientific predictions, the reflection numbers should start to rise again in 2027.
After a two-year absence, I decided to be active on 144 MHz this year for the Perseids Meteor shower. At the end a total of 44 QSOs could be logged, including 13 new QTH locators. In retrospect, I have to say that the shower had significantly worse reflections this year compared to previous years.
This picture shows my signal, recorded by Nick US8AR in KO60RR and Andy UT4UEP in KN49WV. It is the same burst with a duration of over 30 seconds, recorded by both on August 11, 2020 at 10:45:30 UT. Thanks to Nick and Andy for these interresting screenshots.
From August 04, 2020 until August 05 2020 the ISS send again pictures in Slow Scan Television. The images are always transmitted in Mode PD 120 on 145.800 MHz in Frequency Modulation. The following images were received with a 14 Element Yagi and decoded with MMSSTV software. More information about Amateur Radio on the ISS can be found on the ARISS website and the ARISS Blogspot.
50 MHz: Also the month of July brought some nice Es openings to Japan and minor openings to Florida and, after a very long time, again to Brazil. No new DXCC could be worked in July.
Overall the year 2020 ended up with 9 new DXCC Entities. Particularly worth mentioning are those 82 stations from Japan, never worked that much before on the Magic Band.
144 MHz: Regarding Sporadic E July was also a disappointed month. Only OH7RJ was heard and worked during a very short opening on July 3rd.
50 MHz: Seasonally 6m was open every day within Europe. In addition, there were very long openings to Asia and North America. Towards the US and Canada, the terrain of my QTH rises to 10 degrees elevation, so at all again only a few stations from the west have been heard and worked.
In total, six new DXCC entities could be worked in May: 4S7VG (Sri Lanka), BU2EL (Taiwan), DU1IST (Philippines), HL2ZN (South Korea), JT1CO (Mongolia) and VR2XYL (Hong Kong).
144 MHz: Regarding Sporadic E, this June was a real disappointment. Only on June 21st there was a brief opening to the east and just two contacts could be logged. RU3GX, R3KBF, UA3QHF were heard only.
The next step in my moonbounce activities has been reached: 23cm!
Many years ago I got this beautiful 1.8m full-size dish and it was lying around uselessly. Hey, 1.8m diameter is a bit small for EME, but why not give it a try? 1296 MHz would be nice and at least the big guns should be heard. To make the long story short: After a few setbacks, measurements and optimizations, the time had finally come and on May 26, 2020, the first contact with UA3PTW was complete. Now, after a week there are 32 different stations in the log, 5 continents have been reached and even two nice QSO’s in CW. My expectations were more than exceeded and now it is time to optimize further details.
See you off the moon!
50 MHz: After a few short band openings in April within Europe, things really got going in May. The first intercontinental opening for me took place this year on May 18 towards Asia, especially Japan and China. On May 25th XV1X suddenly appeared out of nowhere and brought the first new DXCC of the season.
Since this QTH is unfortunately not working so well to the west, only a few contacts were made into the Caribbean on May 29th. The pileup around various stations from Jamaica was huge and luckily 9Z4Y could be logged as another new country.
For the first time ever Saudi Arabia showed up on 6m and 7X1SJ was the first one I got among others.
In total, three new DXCC entities could be worked in May: 7X1SJ (Saudi Arabia), 9Y4D (Trinidad & Tobago) and XV1X (Vietnam).
144 MHz: The first very short band opening 2020 at 144 MHz from here to TA and SV took place on May 25th. Just two stations could be heard and worked.
The next day the band opened towards east into UA4 and UA6. As the center of reflection was very far to the east, stations from the Saxony area were, as so often, clearly preferred. Nevertheless UA4ALQ was worked over a distance of 2.437 km.
The best ES opening of the month took place on May 29th. Spanish stations could be heard in CW, SSB and FT8 for hours. The 2m band sounded like shortwave. This time I focused in particular on new squares and DXCC and with CN8LI in Morocco DXCC # 95 came into the log. What a great day!
