\page installation Installation
|
|
|
|
Warning: from version 9.1.1 and higher, Jasper library is dropped and openjpeg is used
|
|
We need openjpeg2 (e.g. libopenjpeg2.1 or higher) and not libopenjpeg 1.5
|
|
|
|
\section step1 Step 1: Prerequisites
|
|
Before you can compile QSSTV make sure that you have installed the following software
|
|
- g++
|
|
- libfftw3-dev
|
|
- qt5-default
|
|
- hamlib-dev
|
|
- libasound2-dev
|
|
- libpulse-dev
|
|
- libopenjp2-7
|
|
- libopenjp2-7-dev
|
|
- libv4l-dev
|
|
|
|
<p>On Ubuntu, Debian or Mint you can type:
|
|
|
|
<pre>sudo apt-get install g++ libfftw3-dev qt5-default libpulse-dev</pre>

|
|
<pre>>qsstv</pre>
|
|
If you have problems compiling the software, please give as much information as possible but at least:
|
|
- Linux Distribution (e.g. Ubuntu 18.04)
|
|
- QT Version (e.g Qt 5.4.1)
|
|
- Dump of the compile process showing the error
|
|
|
|
\page gettingstarted Getting Started
|
|
|
|
The program is build around 3 windows
|
|
- Receive window: Receive functions for SSTV and DRM
|
|
- Transmit window: Transmit functions for SSTV and DRM and camera control
|
|
- Gallery window: History of received images, transmit images and templates
|
|
<br>
|
|
The program will remember the last position and the size of each window on restart.
|
|
|
|
Start the program and follow the configuation and calibration instructions below.
|
|
|
|
\page config Configuration
|
|
|
|
Before we can use QSSTV you need to set some configuration options.
|
|
\image html config.png
|
|
The configuration tool is accessed through the "Options" menu in the receive window.
|
|
The following tabs are available
|
|
<br><br>
|
|
\anchor operator
|
|
\li Operator Settings
|
|
<br><br>
|
|
\image html config1.png
|
|
<br><br>
|
|
- Call sign
|
|
- First Name
|
|
- Last Name
|
|
- QTH
|
|
- Locator (Grid Square)
|
|
<br>The above information can also be used in templates (see also \ref editor93 \ref editor94)
|
|
<br>
|
|
- Allow other users to see your online status via the notification server
|
|
<br>The text will be added to the notification send to the hybrid server<br>
|
|
|
|
\li Directories
|
|
<br><br>
|
|
\image html config2.png
|
|
<br><br>
|
|
- RX SSTV Images: directory for saving the SSTV received images
|
|
- RX DRM Images: directory for saving the DRM received images
|
|
- TX Images: directory for images to transmit
|
|
- Templates: directory where the template files are stored
|
|
- Audio Records: directory for audio files (where you save/read recorded audio files)
|
|
- Save TX images in TX SSTV or TX DRM directory: if selected the TX image will be saved
|
|
- Documentation: URL of the user manual (if you copied the manual locally then you can point to it with e.g. file:///usr/share/doc/qsstv/manual
|
|
<br><br>
|
|
|
|
\li Gui
|
|
<br><br>
|
|
\image html config3.png
|
|
<br><br>
|
|
- Stretch: if checked, the image will fill the receive window (keeping the aspect ratio) else it will be displayed as is.
|
|
- Background Colour: colour used for image borders and background in the gallery
|
|
- Image Background Colour: Default image background
|
|
Push the push button to select the colour selector.
|
|
- Gallery: Rows and columns: set-up the number of rows and columns to be used in the Gallery tab. If you're running on a slow CPU (like on a Raspberry Pi) select row=1 and columns=1.
|
|
- Slow CPU: Select this option if you're running on a slow CPU (e.g. Rapsberry Pi)
|
|
- Low Resolution: Select this option if your display is for example 800x480. This options sets the maximum vertical resolution of QSSTV to less than 480 lines. It therefore removes some features
|
|
from the receive window (Rx Notification Window in DRM) and the transmit window (Image replay Preview and TX Notifications in DRM mode).
|
|
You can toggle to and from full screen by using the CTRL_F key combination.
|
|
- Ask for confirmation when deleting file: When you delete a file from the gallery it will ask for confirmation before deleting the file, otherwise it will simply delete the file.
|
|
- Ask for confirmation when closing QSSTV: if checked, ask: "Are you sure to exit QSSTV" before closing the program

|
|
- Swap left and right channel
|
|
- If selected, audio will be sent on the right audio channel instead of the left channel (e.g Kenwood tranceivers using USB sound interfaces)
|
|
- PTT tone on other audio channel
|
|
- A tone will be sent on the right channel to enable PTT. If the above "Swap left and right channel" is selected, it will be sent on the left channel.
|
|
<br><br>
|
|
Note: To playback an audio file, be sure the format is of type wav and has a samplerate of 48000 samples/second. You can always open the file with audacity and export the file to adapt the type and/or

\li CAT
|
|
<br><br>
|
|
\image html config5.png
|
|
<br><br>
|
|
|
|
- Special Serial Port: If you have a separate serial interface to control the PTT you can enable Special Serial Port to control it.
|
|
You can select RTS and or DTR in inverted or non-inverted mode (i.e. +RTS will assert RTS at +12V when the PTT is active
|
|
and -RTS will assert RTS at -12V). +RTS and/or +DTR is used most of the time.
|
|
The same goes for DTR.
|
|
<br>
|
|
You cannot select both +RTS and -RTS or +DTR and -DTR at the same time.
|
|
- Enable Hamlib Cat Interface
|
|
- Radio Model: drop down list from the radio models
|
|
- CIV Address: only used for ICOM, if left empty, the default address of the radio will be used
|
|
- Serial Port/host: either the serial port (e.g. /dev/ttyUSB0) or the host address (e.g. localhost:4532)
|
|
- Handshake, Parity, Data bits, Stop bits, Baud rate: serial port settings
|
|
- PTT Serial Port: serial port (e.g. /dev/ttyS0) only used if "Enable PTT serial Interface" is selected
|
|
- PTT Control via: If the radio uses a CAT command to activate Transmission then select "CAT". If you have a radio that does not support such a CAT command, you can
|
|
let Hamlib use the RTS or DTR on the serial port specified by "PTT Serial Port".
|
|
- There are 2 CAT ports:
|
|
-CAT (voice port): the normal setting
|
|
-CAT (data port): to be used with some kenwood tranceivers(e.g. kenwood TS-480) to force data port instead of audio port (source: David VK3DCU)

\anchor flrigconfig
|
|
- Enable XMLRPC
|
|
This allows you to connect to the Flrig program using the XMLRPC protocol. Flrig will handle all the communication with the transceiver (including PTT).
|
|
The Flrig version must be lower then 1.3.4x
|
|
|
|
|
|
- TX Delay: The program will wait for the selected delay before transmitting any audio.
|
|
|
|
|
|
Note: The option Enable XMLRPC excludes the use of hamlib.
|
|
|
|
A sample set-up of Flrig (version <1.3.4x)is shown below.
|
|
<br><br>
|
|

You can now also connect via Hamlib to Flrig (model number 4).
|
|
There are two prerequisites
|
|
- Hamlib version 3
|
|
- Flrig 1.3.4x or higher

\li FTP
|
|
<br><br>
|
|
\image html config8.png
|
|
<br><br>
|
|
This is used to save the received images to an FTP server. The images will also still be saved in the local rx folder.
|
|
- Enable FTP: enable ftp operation
|
|
- FTP Port: default 21
|
|
- Default Image Format: select the image format from the drop down box
|
|
- Remote Hostname: hostname of the ftp server (e.g. myftp.home.net or 192.168.0.1)
|
|
- Remote directory:the ftp server directory where you'll store the images
|
|
- FTP Login name: your login name on the server (can be anonymous)
|
|
- FTP Password: if you need one, otherwise leave blank
|
|
- Image store:
|
|
image1 to image30: The files will be saved under the generic name imageXX, where xx ranges from 1 to 30. When a new image arrives, the old images are shifted down
|
|
(i.e. image29 becomes image30, image28 becomes image 29 etc ..) and the new one is stored as image1.
|
|
- add image format extension: if checked, the xetension is added to the filename (e.g. image2.png)
|
|
- file name: the image (or other type of file) is stored with a file name derived from the mode (SSTV) or from the file name transmitted in DRM.
|
|
|
|
Note: This FTP server is unrelated to the FTP server for Hybrid Mode.
|
|
|
|
You can test the connection by clicking the Test connection button. It will set-up a connection to the server and send a test file to check if all parameters are correct.
|
|
You will either see a pop-up with "Connection OK" or an error message showing the reason of the fail.

|
\li Hybrid
|
|
<br><br>
|
|
\image html config10.png
|
|
<br><br>
|
|
- Enable Reception in Hybrid Mode: allows reception of hamDRM in hybrid mode. If not enabled, hybrid mode files will not be shown or stored.
|
|
- FTP Port: default 21 (cannot be modified at this moment for compatibility with EasyPal)
|
|
- Send RX Notifications in Hybrid mode: The notifications will be send to the server used by the sender
|
|
- Host: hostname of the ftp server you will use
|
|
- Host: the ftp server where the hybrid images will be send to.
|
|
- Login: the login name on the server
|
|
- Password: will be encrypted
|
|
- Directory: default empty
|
|
|
|
Login name, password,hostname and directories will be encrypted before being sent on the air.
|
|
|
|
The directories on the FTP server must be created at root level.
|
|
- HybridFiles1 -- where the hybrid files are uploaded
|
|
- RxOkNotifications1 -- where the notification are sent when receiving an DRM image
|
|
- OnlineCallsigns1 -- where the call sign and info text is sent
|
|
|
|
If a directory is specified (e.g test) then the following directories must be cretaed:
|
|
- test/HybridFiles1
|
|
- test/RxOkNotifications1
|
|
- test/OnlineCallsigns1
|
|
|
|
QSSTV will not create those directories for you.
|
|
|
|
You can test the connection by clicking the Test connection button. It will setup a connection to the server and send a test file to check if all parameters are correct.
|
|
You will either see a pop-up with "Connection OK" or an error message showing the reason of the fail.
|
|
|
|
There are some public servers you can use.

|
|
<br><br>
|
|
- List of selectable frequencies. Click Add to add a new combo frequency/mode/modulation/passband. Enter the frequency and select the mode,modulation and passband type.<br>
|
|
To move a frequency/mode/modulation/passband up or down the list, click first on the entry in the table and then click on one of the arrow buttons.
|
|
- Filter 1 will be selected if PKTxxx is used on ICOM (hamlib limitation).
|
|
- Hamlib Data Command: (only used with Hamlib)
|
|
Hamlib Data Command allows you to send a "raw command" that will be executed when you change frequencies.
|
|
|
|
- Example: FEFE7AE01A060101FD and Hex button checked: will put the Icom in data mode D1 (LSB, USB or FM) and the Filter 1.
|
|
|
|
- Hex: if checked the text is interpreted as hex values else it will be interpreted as a regular ASCII string.
|
|
|
|
- Note 1: you can put any valid raw command here, it will be send on every frequency change
|
|
|
|
- Note 2: Flrig does not support FM data modes.
|

\page volume Volume Settings
|
|
|
|
You will not find a volume setting within QSSTV.<br>
|
|
The volume (audio out and audio in) are handled by the OS.<br>
|
|
|
|
Most distributions use Pulseaudio interface.<br>
|
|
You can select the audio card settings through the audio applet by right clicking on the Speaker icon and selecting the Sound Preferences.<br>
|
|
|
|
Pulseaudio is the easiest to setup because the audio levels can be set per application.<br>

\page calib SSTV Calibration
|
|
Calibration is only needed for SSTV mode.
|
|
|
|
All SSTV applications need an accurate and stable clock. The accuracy of a PC clock is not always correct.
|
|
Therefore it's necessary to execute some sort of calibration.
|
|
You need to synchronize your PC with an network time server via the ntp protocol.
|
|
Every Linux distribution has some configuration tool that allows you to install the ntp client. Be sure it's active.
|
|
You can check it with:
|
|
<pre>
|
|
>ntpq -p
|
|
</pre>
|
|
|
|
|
|
The selected ntp server should have an asterisk in the first column.
|
|

|
|
|
|
|
|
Newer sytems default install timesyncd instead of ntpd.
|
|
timesyncd connects to the same time servers and works in roughly the same way,
|
|
but is more lightweight and more integrated with systemd.
|
|
The status of timesyncd can be checked by running timedatectl with no arguments.
|
|
<pre>
|
|
>timedatectl
|

\image html bsr_select.png
|
|
By default the latest received file is selected (you can select another one through the drop-down box).
|
|
<br>There are two modes: EasyPal and Compatible. EasyPal mode is more advanced and is normally used as EasyPal is the de facto standard on Windows and QSSTV also uses this mode in BSR reception.
|
|
<br>Note: BSR is greyed out in SSTV.
|
|
<br><br>
|
|
- WF ID: send callsign in waterfall - this is a short-cut to send your own callsign in the waterfall

- adjust your recording level to half scale.
|
|
|
|
SSTV tab:
|
|
- Use VIS Code: the reception will only start if a correct VIS code is received. If left unchecked, QSSTV will auto-detect the modes (this is the most used method).
|
|
- Auto-slant: A lot of times the receive clock of the local station is not equal to the transmit clock of the sending station. The result is a slanted image.
|
|
If The auto-slant is activated, the program will automatically try to compensate for those clock differences.
|
|
You may notice a momentary freeze of the image build-up while the program is recalculating the image.
|
|
- Auto-save: When the program detect the end of the image, the image will be saved to disk.
|
|
- Save if Complete %: Auto-save if the image is at least completed for the indicated percentage.
|
|
- Mode: you can either select AUTO or one of the supported SSTV modes.
|
|
When AUTO is selected, the program will try to determine the mode of the image it is receiving.
|
|
If a specific mode is selected the program will reject all images except if they are transmitted in the selected mode.
|
|
- Sensitivity: Low, Normal, High and DX.
|
|
When the Sensitivity is set to DX the signal will run until the end of the image before resynchronization.

Settings for HF and VHF/UHF are very different.
|
|
|
|
General rules of thumb:<br>
|
|
Mode A: most demanding, used on VHF/UHF<br>
|
|
Mode B: use on HF/VHF/UHF<br>
|
|
MODE E: least demanding, used on HF<br>
|
|
|
|
QAM 64 : most demanding, used on VHF/UHF in really good conditions<br>
|
|
QAM 16 : used on VHF/UHF in fairly good conditions sometime also on HF<br>
|
|
QAM 4 : least demanding, used on HF <br>
|
|
|
|
Bandwith:
|
|
- 2.5 kHz: VHF/UHF
|
|
- 2.2 kHz; HF
|
|
|
|
Protection:
|
|
- Depends on the conditions, leave it on High
|
|
|
|
Interleave:
|
|
- leave it on Long on all bands
|
|
|
|
Reed-Solomon:<br>
|
|
Reed-Solomon provides Forward Error Correction by adding redundant bytes per block of 255 bytes.<br>
|
|
More errors can be corrected when more redundant bytes are used.<br>
|
|
This adds overhead to the transmission.
|
|
|
|
- RS1 increased by 13%
|
|
- RS2 increased by 33% most often used
|
|
- RS3 increased by 60%
|
|
- RS4 increased by 99%
|
|
|
|
Always use Reed-Solomon encoding on HF bands.

|
|
|
|
When the image you transmitted is not correctly received, the other station can send a BSR. When you receive a BSR and it is destined for you, then the above popup will show.
|
|
You can either send the fix or cancel.<br>
|
|
If the BSR is not for you then the following window will pop-up for a few seconds.

|
\image html spectrum_wf.png
|
|
Note: the settings Max dB, Range and AVG do not influence in any way the sensitivity of the reception in SSTV or DRM.
|
|
\image html spectrum1.png
|
|
|
|
Max dB:
|
|
- defines the audio level at the top of the spectrum display
|
|
|
|
Range
|
|
- defines the dynamic range in dB to display
|
|
|
|
Avg:
|
|
- this is the integration factor to smooth the spectrum display. Values are between 0.6 and 1 (0.88 is a good value).

|
|
- RX SSTV: SSTV images are stored on disk and shown here if the Auto-save is enabled in the receive window and the minimum percentage is reached
|
|
- RX DRM: All images received in DRM mode are stored on disk and shown here.
|
|
- TX SSTV: When sending an image in SSTV mode then the resulting images is stored on disk and shown here (this includes the template overlay).
|
|
- TX DRM: When sending an image in SSTV mode then the resulting images is stored on disk and shown here (this includes the template overlay).

\page editor93 Editor version 9.2 and 9.3
|
|
The editor can be used for regular image editing and for the creation and editing of template images.
|
|
Template images are used as overlays. They will be dynamically adapted when you select the template in the TX-window.
|
|
While in edit mode, you can change all the attributes (such as size, position, colours etc ...). If you save the canvas as an
|
|
image, the scene will be rendered (i.e. flattened) and become a single image object. If you save the canvas as a template, all objects
|
|
will be accessible again when loaded.
|
|
|
|
<br>
|
|
To create an object, click on the left menu to select the type of object (e.g circle) and then click on the canvas where you want the object positioned.
|
|
Just click on an item to select it. A outline of the item will be shown by a dashed line.
|
|
If you hoover over the object you will see the cursor change to a hand-icon (in the middle of the object) to move it, or to a resize-icon if you are on a border.
|
|
|
|
The attributes (line colour, fill colour, gradients etc ..) that are active in the top menu will be used to create the item.
|
|
Object have also a z-component, i.e they can be in front our behind another object. This can be changed by right clicking on the item and use the Arrange selection.

For the use of macro's see \ref macros
|
|
|
|
\page macros Macro Text
|
|
|
|
You can use macros to expand text add runtime. When layouting templates remember that % macros will be replaced by the final text.
|
|
<br> Example: %v will expand to QSSTV.9.4.3.
|
|
So leave enough room to place the final text.
|
|
|
|
Following macro's are supported:<br>
|
|
Macro's where the value is defined in the configuration
|
|
\li %%m - my callsign
|
|
\li %%q - my QTH
|
|
\li %%l - my locator
|
|
\li %%n - my last name
|
|
\li %%f - my first name
|
|
|
|
Macro's where the value is entered in the TX-window prior to transmission
|
|
\li %%c - call of the contacted station
|
|
\li %%r - RSV (radio-strength-video best is 595) You can also input free text as is sometimes required for contest (e.g. 595#007 or Good Copy)
|
|
\li %%o - name of the operator of the contacted station
|
|
\li %%x - comment1
|
|
\li %%y - comment2
|
|
\li %%z - comment3
|
|
|
|
Note: comment 1,2 and 3 can be multi-line.
|
|
|
|
Macro's where the value is defined by the system
|
|
\li %%t - time in hours:minutes format
|
|
\li %%d - date in year/month/day format
|
|
\li %%v - qsstv_version
|
|
\li %%s - SNR only in DRM mode
|
|
- in version 9.3 only used in the WF Text see also \ref statusbar
|
|
- in version 9.4 and higher used in the WF Text and in the template images

\page repeater Repeater
|
|
|
|
This feature allows you to repeat images in both SSTV and DRM mode.
|
|
see also \ref repAnchor "Repeater Configuration"
|
|
|
|
It will first receive an image and after decoding it will retransmit the processed image.
|
|
The repeater acts like a parrot, it is not just retransmitting the audio.
|
|
|
|
|
|
When the repeater is inactief for a time (idle time) specified in the repeater configuration, 1 of 4 images will be transmitted.
|
|
The overlay can be specified in the configuration.
|
|
|
|
The retransmitted images are send in the mode selected in the Transmit window.
|
|
For SSTV the mode can be the same as the mode of the received image.
|
|
|
|
The repeater does not allow for cross-mode (i.e SSTV repeated in DRM or vice versa)
|
|
|
|
Images will only be repeated if:
|
|
- For DRM: the image was received without errors or after correction.
|
|
- For SSTV: the image was received and the Complete precentage has been met.
|
|
|
|
In DRM the repeater will never use Hybrid mode to repeat the image.
|
|
|

\page credits Credits
|
|
- SSTV:<br>
|
|
Many thanks to all testers and users of QSSTV - too many to name them all.
|
|
<br><br>
|
|
- DRM:<br>
|
|
I started developing the DRM functionality in QSSTV after studying the excellent work Ties Bos (PA0MBO) did on txrxamadrm.<br>
|
|
see: http://www.pa0mbo.nl/ties/public_html/hamradio/txamadrm/index.html<br>
|
|
The software is NOT based on the hamdrm.dll but on DIORAMA (http://nt.eit.uni-kl.de/static/diorama/index.html)<br>and adapted by PA0MBO. For more information , see the manual of txrxamadrm.
|
|
|
|
This document contains references to Easypal (by VK4AES). Erik Sundstrup was kind enough to give me permission to use the extended BSR functionality and the DRM Hybrid mode.
|
|
Easypal was used extensively to test my program. <br>
|
|
<br>

|
|
|
|
Erik is now silent key as of 14th march 2015. We will miss him.
|
|
<br>
|
|
I hope there will be other OM's that take up the maintenance,enhancements and development of EasyPal so that people running Windows will continue to enjoy his software.
