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

Posted: 27 Jul 2020 02:30 PM PDT https://amsat-uk.org/2020/07/27/getting-started-on-qo-100/


On Monday, July 27 Dom Smith M0BLF gave an online talk Getting started on QO-100 as 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 Eshail-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.

It is planned Russian cosmonauts will transmit amateur radio Slow Scan Television (SSTV) images from the International Space Station (ISS) during August 4-5 on 145.800 MHz FM (likely using PD-120). It should be receivable across the British Isles and Europe.

On July 9, ESA Education had Tweeted:

We are expecting the ISS to transmit pictures in the next weeks for the
45th anniversary of the Apollo-Soyuz test project. This is a perfect opportunity to try this activity for yourself!

Apollo–Soyuz was the first international space mission, carried out jointly by the United States and the Soviet Union in mid-July 1975.

An announcement made July 27 on the ARISS SSTV Blog says:

The final crew schedule for the week of Aug 3-9 was released recently and
it showed a MAI-75 activity scheduled for Aug 4 and 5. This is soon after
the Space X Demo-2 undock so changes to that event could impact the
schedule.

The current dates and times of the planned activity are as follows:

Aug 4 (12:25-18:10 UTC) is setup and day 1 operations.

Aug 5 (11:15-18:45 UTC) is day 2 operations and close out.

This is the Moscow Aviation Institute SSTV experiment that is active for orbital passes over Moscow, Russia. It has traditional been PD-180 or
PD-120 and transmitting on 145.800 MHz.

The ISS puts out a strong signal on 145.800 MHz FM and a 2m handheld with a
1/4 wave antenna will be enough to receive it. Many FM mobile and base
station rigs can be switched been wide and narrow deviation FM filters. For best results you should select the filter for wider deviation FM (25 kHz channel spacing). Handhelds all seem to have a single wide filter fitted as standard.

The space agency ESA has released a video ‘How to get pictures from the International Space Station via Amateur Radio’ along with a collection of Tutorial videos explaining how to receive ISS Slow Scan TV (SSTV) pictures
for different computers and mobile devices
