AMSAT-DL have announced this year’s Symposium on Saturday, September 26, will be streamed live on YouTube and most of the lectures will be in English to cater for an international audience.

Matthias DD1US writes on the AMSAT Bulletin Board:

Unfortunately, the AMSAT-DL Symposium planned for September 26th and 27th, 2020 cannot take place this year in the usual manner.

Since the health of everyone is very close to our hearts and the legal framework currently leaves no other option, we have decided not to hold a meeting on site in Bochum this year. We regret this very much, but the premises only allow an occupancy of less than 20 persons.

A “social” meeting with dinner is unfortunately not possible either, nor is a flea market and other activities, such as the QO-100 User Meeting, which happened for the first time during the HAM Radio Fair in Friedrichshafen in 2019.

Instead, we will broadcast the symposium as an “online” meeting in DATV via the broadband transponder of QO-100 and on the Internet on the YouTube channel of AMSAT-DL at https://www.youtube.com/user/amsatdl

Enclosed is the preliminary schedule for September 26th 2020 (all times in CEST=UTC+2):

09:00 (07:00 GMT, 08:00 BST) Welcome, Introduction, Agenda – Matthias DD1US

Vega launch of three satellites with ham radio payloads

Vega VV16 launch

Vega VV16 launch

Three satellites with amateur radio payloads were on the Vega VV16 launch that took place at 01:51:10 GMT on Thursday, September 3, 2020.

Earlier on the AMSAT Bulletin Board Christophe Mercier had posted:

The Vega rocket (VV16) is scheduled to leave Kourou on 02 September 2020 at 3h36 CEST [launch was postponed until 01:51 GMT on Sept 3] with 53 satellites on board.

One of the satellites that will be leaving is the Amicalsat satellite built by the CSUG (Centre Spatial Universitaire Grenoblois). The measurements made by the satellite will be available to all. They will allow radio amateurs to use them for propagation predictions.

The project’s website (in English) has just been put online http://amicalsat.univ-grenoble-alpes.fr/

The Amsat-Francophone supported this project http://site.amsat-f.org/amicalsat/

A software (Linux & Windows) is provided for decoding the telemetry and sending it to the database (SatNogs). The user manual is available (in English) https://code.electrolab.fr/xtof/josast/-/blob/master/ApplicationAmicalsat/src/site/markdown/UserManual.md

Reports are welcome. Thank you for your help.

The first 5 people who receive a frame from AmicalSat will receive a gift.

RSGB Tonight @ 8 Video – Getting started on QO-100

Es'hail-2 Qatar-OSCAR-100On Monday, July 27 Dom Smith M0BLF gave an online talk – Getting started on QO-100as part of the RSGB Tonight @ 8 live webinar series.

Dom’s lockdown project was to complete a set up for the QO-100 amateur radio transponders that are hosted on the geostationary satellite Es’hail-2. This was the first amateur radio payload to be put into a geostationary orbit and provides constant and reliable coverage for amateur voice, data and television contacts over the whole of Africa, Europe and the Middle East and even as far as Brazil in the west, and Thailand in the east.

Getting started on QO-100 is a talk in two halves: first we’ll watch the video, showing the particular set-up chosen—and there are many!—and then there will be chance for a Q&A. The equipment list can be see at https://www.domsmith.co.uk/blog/2020/07/27/rsgb-webinar-on-qo-100/

Watch Getting Started on QO-100 by Dom Smith, M0BLF

Dom Smith, M0BLF has been a radio amateur for nearly 25 years since being licensed at the age of 14 in 1996. He is an active member of the Camb-Hams and Cambridge University Wireless Society (CUWS), and may often be heard contesting, climbing hills for Summits on the Air, and assisting Cambridgeshire RAYNET. He also enjoys travelling for DXPeditions, most recently as JW/M0BLF, VP2MUW and ZC4UW, and he manages QSL cards for most CUWS trips. On top of all that, he volunteers with Cambridge 105 Radio, the local community broadcast station, on the engineering team.

Professionally, Dom works as a Cloud Solutions Architect in the software team at the Royal Society of Chemistry and he holds a PhD in Hispanic Studies.

Ofcom statement on 5725-5850 MHz

On Friday, July 24, Ofcom released their statement on 5725-5850 MHz and 5925-6425 MHz.

The main points are:
• Make 5925-6425 MHz available for Wi-Fi and other RLAN technologies
• The release of this spectrum will also enable very low power (VLP) outdoor use
• Remove the Dynamic Frequency Selection (DFS) requirements from channels used by Wi-Fi in the 5725-5850 MHz Amateur and Amateur Satellite Service allocation

The Amateur Satellite Service weak-signal downlink band, 5830-5850 MHz, is used by amateur payloads on Deep-Space and Interplanetary spacecraft as well as by satellites in Low Earth Orbit (LEO). Increased use of Wi-Fi across these frequencies could obliterate the weak amateur satellite signals.

OSCAR Satellite QSO Party 1 Aug – 22 Sept

Fun in space with Amateur RadioThe objective of the AMSAT-UK OSCAR Satellite QSO Party is to encourage all radio amateurs around the world to get on the air and make contacts via satellites during northern hemisphere summer. We would like to attract both seasoned die-hard operators as well as all newcomers who are just getting involved.

While points are given per QSO this isn’t a contest, but we hope it will encourage people to get on the air and enjoy the excitement of making contacts through satellites.

The AMSAT-UK OSCAR Satellite QSO Party will be supported by an online leaderboard which will be available from the start of the event which runs from 00:00 GMT on 1st August until 23:59 GMT on 22nd September.

Prizes will be awarded to those from first to thirteenth place and are open to both AMSAT-UK and non-members around the world.
● First Place £250 Amazon Voucher
● Second Place £150 Amazon Voucher
● Third Place £50 Amazon Voucher
● Fourth to Thirteenth Place One Year AMSAT-UK Membership

Unauthorized transmissions in 144 MHz satellite allocation

Water Vitalizer Interference - DC4CX

Water Vitalizer Interference – DC4CX

The DARC reports unauthorized transmissions are taking place in the 144 MHz satellite segment of the 2m amateur radio primary allocation.

A translation of the DARC post reads:

In the 144.010 MHz to 144.020 MHz range, illegally operated transmitters are increasingly being operated as “water vitalizers” or “water energizers”. The manufacturer specifies 144.015 MHz as the transmission frequency in its product description.

The DARC EMC department asks for further information with location information about conspicuous signals in this frequency range, in preparation for collective complaints.

The devices apparently generate fields with considerable field strength and a long range. The signals appear increasingly in the morning or in the evening. The illegal transmitters are typically in operation for 5 to 60 minutes (integer multiples of 5 minutes). The signal is generally very stable in frequency, but occasionally shows short-term fluctuations of up to a few 100 Hz. Otherwise the carrier is not further modulated.

The frequency range 144.000 MHz to 146.000 MHz is assigned to the amateur radio service in Germany as the primary exclusive user.

A video of the interference caused by these devices and a map showing some of the cases so far detected in Germany can be seen at https://www.darc.de/der-club/referate/emv/
