Setting up raspberry pi 3 and QSSTV latest 9.2.4 GB8SSD special update / ARISS 20 anniversary

You need an external usb sound card

Next set up alsa mixer and increase the microphone gain!

In a command line window type:
Sudo alsamixer

Press the F6 key to select sound card

Choose the usb sound card using up and down arrow keys and press enter.

Use arrow right key to select Mic, use up arrow to increase to about 52.

Press escape key to return to command line

To install QSSTV type:

sudo apt-get install g++ libfftw3-dev qt5-default libpulse-dev
sudo apt-get install hamlib-dev libasound-dev  libv4l-dev
sudo apt-get install libopenjp2-7 libopenjp2-7-dev

Next download and install QSSTV

mkdir downloads
cd downloads
wget http://users.telenet.be/on4qz/qsstv/downloads/qsstv_9.2.4.tar.gz
tar -xvzf qsstv_9.2.4.tar.gz
cd qsstv_9.2.4
qmake
make
sudo make install



You can now run the program by typing qsstv at the prompt of a terminal session, or make a short cut on your desktop.


qsstv



























Click on configuration





















Click on sound and copy the above settings



Input and output set to your usb sound card.



Set the sound to alsa.









Plug an external microphone into the sound card. Turn up your radio and watch your pictures get decoded.



Space station is 145.800 fm



However 14.230 upper side band is more regular broadcast.



You can also hold the microphone near a sstv recording or YouTube video.







Have fun let me know how you get on!







We were really happy to hear from Lee DV8BVK:

"Hello Chertsey Radio Club,







My name is Lee, DV8BVK here in the Philippines. I am very
thankful of your article/blog re install of QSSTV to Raspberry Pi 3 with the
USB sound card. I followed all the instruction and put it to the test last july
22,2017 of the ARISS SSTV event. Thank you very much. "

June 26: Abort flight:











June launch attempt



During the 26 June launch attempt, there was a launch abort at T-6 seconds, followed by a pad fire about ten minutes later.[3][4]





Commentary: "We have a cut off."
"NTD we have a RSLS (Redundant Set Launch Sequencer) abort."
Commentary: "We have an abort by the onboard computers of the orbiter Discovery."
"Break break, break break, DLS shows engine one not shut down."
"OK, PLT?"
"CSME verify engine one."
"You want me to shut down engine one?"
"We do not show engine start on one."
"OTC I can verify shutdown on verify on engine one, we haven't start prepped engine one."
"All engines shut down I can verify that."
Commentary: "We can now verify all three engines have been shut down."
"We have red lights on engines two and three in the cockpit, not on one."
"All right, CSME verify engine one safe for APU shutdown."
"If I can verify that?"
"OTC GPC go for APU shutdown."[5]





Mission Specialist Steve Hawley was reported as saying following the abort: "Gee, I thought we'd be a lot higher at MECO (Main Engine Cut-Off)!".[6] About ten minutes later, the following was heard on live TV coverage:





"We have indication two of our fire detectors on the zero level; no response. They're side by side right next to the engine area. The engineer requested that we turn on the heat shield fire water which is what could be seen spraying up in the vicinity of the engine engine bells of Discovery's three main engines."





While evacuating the shuttle, the crew was doused with water from the pad deluge system, which was activated due to a hydrogen fire on the launch pad caused by the free hydrogen (fuel) that had collected around the engine nozzles following the shutdown and engine anomaly.[7] Because the fire was invisible to humans, had the astronauts used the normal emergency escape procedure across the service arm to the slidewire escape baskets, they would have run into the fire.[8]



Changes to procedures resulting from the abort included more practicing of "safeing" the orbiter following aborts at various points, the use of the fire suppression system in all pad aborts, and the testing of the slidewire escape system with a real person (Charles F. Bolden, Jr.). It emerged that launch controllers were reluctant to order the crew to evacuate during the STS-41-D abort, as the slidewire had not been ridden by a human.[6]



Examination of telemetry data indicated that the engine malfunction had been caused by a stuck valve that prevented proper flow of LOX into the combustion chamber.

Lilacsat 1 and 2 decoder now available on Raspberry Pi (3) image










We spent some time installing and testing out fitting all the GNU radio and demodulators onto a pi image.



Results We needed to trim and trim again but it now works
















The image is available here







So we build GNU radio and gr-satellites and gr-lilacsat from scratch along with all dependencies







GNU radio loads and imports the lilacsat modules (detects funcube / airspy dongles)







The proxy loads and run OK







The front end module loads and displays the graphs just fine
