German Working Group Amateur Radio Television e.V. (AGAF)
Introduction of the association:
The German Working Group Amateur Radio Television e.V. (AGAF) has been working since 1968 to promote above all the picture transmission modes amateur TV, digital TV and slow-scan TV (SSTV) in the German-speaking countries. For this purpose, it has organized annual meetings with expert lectures, which is currently prevented by the Corona crisis. Likewise, the publication of the quarterly members' magazine "TV-AMATEUR" is currently not possible. The AGAF website, which was severely damaged by a hacker attack, is now accessible again: http://www.agaf-ev.org/
A groundbreaking process was initiated in 1995 by Prof. em. Dr.-Ing Uwe E. Kraus, DJ8DW, a long-standing member and member of the board of AGAF e.V., and his team at the University of Wuppertal with the development of an MPEG-II coder and 70-cm-DATV exciter. 100 coders and exciters each were later "produced" by AGAF members and delivered to German and international interested parties. This pioneering work on DATV enabled the world's first QPSK trial operation of a digital-ATV converter in 2001 with the prototype boards on the multimedia repeater DB0KO, which at that time was housed in the high-rise building of Deutsche Welle in Cologne. Since 1999, this modern TV technology has been demonstrated in amateur radio at the AGAF stand of HAMRADIO in Friedrichshafen every year with ever new variants. For example, every year from the Pfänder mountain above Bregenz/OE, in 2003 from the Zepplin and in 2004 from a ship on Lake Constance, and from mobile stations on land, was transmitted and then received at the AGAF stand. The Wuppertal university team received the Rudolf-Horkheimer-Prize of the DARC in 2002 in Friedrichshafen for the pioneering work on DATV.
In the meantime, there are many follow-up projects worldwide and, since the beginning of 2019, even a geostationary TV satellite with a connected digital ATV repeater (Quatar-OSCAR 100), developed by the German group AMSAT-DL. It, besides other signals, transmits digital amateur TV from Brazil to China and from South Africa to Sweden. These DVB-S2 signals are received by a ground station of the co-developers of the British Amateur Television Club (BATC) in South West England and the transponder spectrum is streamed live to the Internet with a chat window for the DATV transponder users: https://eshail.batc.org.uk/wb/
The DATV signals available on the satellite are also received at the German multimedia repeater DB0KO near Cologne (at the new Huerth location), but are automatically evaluated as image signals depending on the data rate and streamed in three windows of the nine-part converter output video to the Internet. They are made visible e.g. by means of the VLC player network stream output: http://www.db0ko.org/db0ko_internet.m3u

RF-Test Solutions – Follow our Journey to higher Performance
From September 2019 on till today Siglent has released several new RF-test instruments or extended existing series. Here is a short summary of the last month’. In September 2019 the SVA1000X Series, a hybrid instrument combining Spectrum Analyzer and Vector Network Analyzer functionality in one instrument, got an upgrade in frequency from 1.5 GHz to 3.2 GHz. With this frequency extension, improvements in performance, like better DANL and more advanced measurements were implemented. The VNA functionality enables the user to conduct complex impedance matching, filter optimization or antenna development. At the same time Siglent released the SSA3000X Plus Series of Spectrum Analyzers. This series will be the successor of the very successful SSA3000X series. It is based on the same platform as the SVA1000X Series, but without VNA. This means that, beside the improved specifications, the X Plus series also offers Touch Screen operation, external mouse and keyboard support and include remote control over the internal webserver and more optional functions like Vector Signal Analysis. All together for only 160.-€ more compared to SSA3000X.
End of February, during the Embedded World in Nuremberg Siglent extended both Series SVA1000X and SSA3000X plus to 7.5 GHz. Roughly one month later there was already the next new product introduction. The new SSA3000X-R series brought real-time frequency analysis capability into the SIGLENT RF product portfolio. The instruments support a real-time analysis bandwidth up to 40 MHz and have a maximum frequency of 5 GHz and 7.5 GHz. The SIGLENT SSA3000X-R real time spectrum analyzers are powerful and flexible tools for complex RF signal monitoring and analysis.
Last but not least Siglent introduced a new RF-Signal Source. This series is available with 4 or 6 GHz, as analog source or as vector signal source. With the Arb. Function Generator SDG6000X and its IQ-Option, the entry level RF generator SSG3000X(-IQE) and the new SSG5000X(-V), Siglent is now able to add three key pieces to your arsenal and help you solve the RF-Design Puzzle.

Swiss DX Foundation (SDXF)
Corona changed all our lives. And our favourite pastime has been affected too: numerous DXpeditions had to be cancelled or at least postponed and it is to be expected that one or the other activity will turn out more expensive than planned. Especially in such times the support of the DX Foundations is even more important.
Let us make the best of the situation and take care of long overdue improvements at our stations. Let us activate the bands and stay in touch. Let us have a look at our QSLs again and maybe apply for one or the other diploma. And maybe we have a little more time than usual to read the reports from recent DXpeditions. Let us dream of faraway places and let us become aware once again what efforts and strains these teams take on to help us to get a "new one".
Stay healthy, we will see you at Lake Constance in 2021 at the latest!
