Welcome
Thanks for visiting cqsstv.com. The ultimate SlowScanTV website.
The core of our website is   max.cqsstv.com   showing worldwide (live) receptions of SlowScan images on various bands and frequencies.

Facebook
You can also find us on Facebook with the highly popular international HF SSTV group:
 SSTV 20m 14.230 MHz HAM (& 80m 3.730 Mhz)

Also we have on Facebook the mainly Dutch language group for The Netherlands, Belgium and surrounding countries.
This group is also the home of the 1st official Dutch SlowScan repeater PI3DFT in The Hague.

SSTV BASICS

To receive SSTV images:

Necessities:
* Radio
* PC-Software: RX-SSTV



Connect the radio with an audio cable to the PC audio-in and install & run the progam RX-SSTV on the PC.




To receive & transmit SSTV images:

Necessities:
* Transceiver (To broadcast in SlowScan you need an HAM radio licence)
* Cat/audio interface or
  Transceiver with inbuild cat/audio interface
* Software: MMSSTV


RX:


Connect the transceiver (with internal cat/audio interface) to the PC.
           
Connect the transceiver thru an cat/audio interface (for Yeasu for example the SCU-17, or use an own build interface) to the PC.



TX: (with HAM radio licence)

     
Make an picture with text in mmSSTV and send it to the transceiver (with internal CAT/Audio interface). The CAT interface will activate the PTT.

           
Make an picture with text in mmSSTV and send it to the transceiver over the CAT/Audio interface. The CAT interface will activate the PTT.

Next wait for reply or check our live worldwide pages (http://max.cqsstv.com) if your transmitted image has been received by someone!





Raspberry Pi 4B & QSSTV

You can install QSSTV very easily from the Raspbian menu, the version installed is then the older version v9.2.6 (from 17 aug 2017)!

Raspberry Pi 4B
       
If you want the latest version you can download it from the ON4QZ download page.
(Currently is that v9.4.4, 20 Oct 2019)

Downloading the latest version can be done from the link above from your browser or
use the Raspberry Pi Terminal


Install latest version v9.4.4 on the Raspberry Pi 4B

First make sure you have the latest updates
Type or copy/paste: sudo apt-get -y update
Type or copy/paste: sudo apt-get -y upgrade

Before going to download the program it's needed to install some libraries that are necessary for QSSTV
Copy & paste: sudo apt-get -y install g++ libfftw3-dev qt5-default libpulse-dev hamlib-dev libasound-dev libv4l-dev libopenjp2-7 libopenjp2-7-dev

To download the QSSTV file, create the directory "cqsstv" (mkdir: make dir), and go inside the directory "cqsstv" (cd: change directory):
type: mkdir cqsstv
type: cd cqsstv

Now download the QSSTV tar.gz file
type or copy/paste: wget -N http://users.telenet.be/on4qz/qsstv/downloads/qsstv_9.4.4.tar.gz



Next you need to unpack the tar.gz file:
type or copy/paste: tar -xvzf qsstv_9.4.4.tar.gz



The program is now unpacked in the directory qsstv_9.4.4, so go into this directory
type or copy/paste: cd qsstv_9.4.4



Now to build the program:
type: qmake



and
type: make
!!! Patience this will take a while... almost 20 min. or longer!



The program is build so now you can install QSSTV
type: sudo make install

QSSTV is now installed on your Raspbery Pi !
(To remove it again one day... use: sudo make uninstall qsstv_9.4.4 from within this directory qsstv_9.4.4 )


You can start QSSTV with the command QSSTV or from the Raspbian menu: Internet > QSSTV
Or at the menu, right click on the icon and add it to the desktop !


QSSTV - Audio
For RX only it is now fairly easy.. just select your audio card in Options > Configuration > Sound



Then you will see on the mainscreen audio or noise coming in...




QSSTV - PTT
For TX we need to set the PTT, for example for the Yaesu SCU-17 interface or Yaesu FT-991/991A with internal interface.
Select from Options > Configuration > CAT
Select there the first option Special Serial Port PTT Serial Port: /dev/ttyUSB1 and select +RTS and +DTR



You should now get the set on TX. Even better when you have audio too !
No audio ? Then go to Options > Configuration > Sound and select Swap left and right channel.



QSSTV - FTP
Especially interesting is that QSSTV has an inbuild file transfer !
Recieved images can be uploaded to your website.
If you want your images also to appear on max.cqsstv.com then use the image 1 to image xx selection !
And send us the website where you have the images.
No website? Or for more information see: Your RX images on max.cqsstv.com!
