===Jan 1 2013===
A new experimental branch called ssl is available in the repo.

The dspserver from the ssl branch allows connection from non-encrypted, open (ie the current) clients such as QtRadio and glSDR, to port 8000+x (where x is usually 0). In addition, it also allow connection from SSL client (such as QtRadio in this branch) to port 9000+x. Note that you will have to port forward 9000+x (as well as 8000+x) in the firewall to allow internet connections from outside.

When you first run dspserver you will receive instructions to generate a self signed security certificate. It will be adequate for our purposes.

One of the advantages of the ssl connection is that your user/password (indeed all data including spectrum and audio) are encrypted so it will be harder for hackers to obtain your user/password from the wire.

Note that the ssl branch's QtRadio will be using port 9000+x when making a connection to a server, so it will NOT work with the dspserver in the other branches which is listening on port 8000+x.

===Dec 26 2012===
Kill switch added to QtRadio (with corresponding dspserver) in master and opengl branches in the git repo.

When you know the user/password (eg you are the server owner), and if you are connected as a slave to your server, you can click the "MASTER" button and usurp the master status. You will become the master and the previous master will be demoted to slave status.

Please use this function sparingly as it may annoy inexperienced glSDR users who are already complaining that the app does not work as they cannot control the vfo and change bands, when the word "slave" in the title bar of the app is staring them in the face :-)

===Dec 25 2012===
I have made updating info in dspserver.conf compulsory instead of optional. There are far too many "UNKNOWN" new stations online.

I have updated opengl branch with version 29 of glSDR:

===Dec 20 2012===
Qt5 final is here:

http://qt-project.org/downloads

Download it and install in /opt/Qt5.0.0 (use sudo when running the installer).

Then set the path with something like:

$ export PATH=/opt/Qt5.0.0/5.0.0/gcc_64/bin:/opt/Qt5.0.0/Tools/QtCreator/bin:$PATH

The git repo branches iw0hdv, master and opengl have been updated to build with Qt5 final (and so they are incompatible with older versions of Qt5 such as the BETA or from the Edgers repo etc).

===Nov 26 2012===
glSDR version 28 is in Google Play and is also available for download.

http://code.google.com/p/sdr-widget/downloads/detail?name=glSDR28.apk&can=2&q=

===Nov 20 2012===
glSDR version 27 is in Google Play and is also available for download. It has been tweaked to support Adreno GPU based devices.

===Nov 18 2012===
glSDR version 25 is in Google Play. Servers list is now updated on each SERVERS MENU invocation. Default frequency for each band is saved on exit in master mode. Band specific default frequencies can be reset to factory default via the BAND MENU.

===Oct 20 2012===
glSDR version 21 is in Google Play. Slave tracks freq, mode and (fake) filter settings of master. Master/slave status is displayed in Title bar.

It has an 80khz FM filter for listening to FM broadcasts and also options for Spectrum Averaging.

===Sep 17 2012===
Added direct support in QtRadio (linux) for the Griffin Powermate Vfo knob. Pushing the knob cycles through vfo step size.

===Sep 15 2012===

Codec2 has been updated to the latest developmental branch. This branch can be downloaded:

svn co https://freetel.svn.sourceforge.net/svnroot/freetel/codec2-dev codec2-dev

This has a new API and it has updated codec2, including a new 3200 bps codec which gives better quality than the 2400 bps codec we have used in the past.

Both master and opengl-qt5 branches have been updated with the new codec2. You need to download the codec2-dev branch above, rebuild codec2, and then rebuild dspserver and QtRadio.

===Sep 14 2012===
glSDR version 10 is in Play Store, For those without access to Play, you can download from:
http://code.google.com/p/sdr-widget/downloads/detail?name=glSDR10.apk&can=2&q=

===Sep 12 2012===
The zoom feature has been ported to glSDR. Ver 9 is now in Play store. For those without access to Play store, you can download the apk here:

http://code.google.com/p/sdr-widget/downloads/detail?name=glSDR9.apk&can=2&q=

With the recent changes, high bandwidth rigs are now adequately supported by ghpsdr3-alex. You can zoom in and out to spectrum/waterfall up to 960 ksps and beyond.

Note that Glenn has also compiled a Windows binary of QtRadio that has the zoom feature and other updates to allow you to access rigs such as HiQSDR and Perseus. allowing you to set Pre-selector, attentuator etc.

===Sep 10 2012===
The LO_offset mechanism has been revamped. The rotation of the spectrum data is now done entirely in dspserver. Therefore clients eg. QtRadio, glSDR, do not have to rotate the data anymore.

This is needed to support the new zoom feature. You can now zoom the spectrum/waterfall on the fly. This feature is very useful for looking closely at a signal, eg 50Hz CW for you to tune spot on, and also for very wide bandwidth hardware such as Peuseus and HiQSDR. We now have servers running 500 ksps or even 960 ksps.

Checkout these videos:

http://code.google.com/p/sdr-widget/downloads/detail?name=g3vbv.ogv&can=2&q=

http://code.google.com/p/sdr-widget/downloads/detail?name=g3vbv2.ogv&can=2&q=

It will take a while for all dspservers to be updated to the lastest code and you must use the latest QtRadio and glSDR (ver 8 or later) for the new LO_offset.

===Sep 5 2012===

Just to summarise the status of support of the just released Qt5 Beta1 for building QtRadio under Linux:

1. You download and install the Qt5 Beta:

http://releases.qt-project.org/qt5.0/beta1/

2. You set the path to point to the qmake you want to use:

$ export PATH=/where/the/Qt/bin/dir/is:$PATH

(For example, mine is:

export PATH=/home/alex/Qt5.0.0beta1/Desktop/Qt/5.0.0-beta1/gcc_64/bin:$PATH

)

3. You can check which version of Qt is active by:

$ qmake --version

(For example, mine is:

alex@alex-Aspire-4750:~/ghpsdr3-alex$ qmake --version
QMake version 2.01a
Using Qt version 5.0.0 in /home/alex/Qt5.0.0beta1/Desktop/Qt/5.0.0-beta1/gcc_64/lib

)

4. The master branch now has conditional compile for Qt5 Beta and for older versions of Qt. Once the above PATH is set for the version of Qt you want, you can just use the usual automake steps to build.

5. The opengl-qt5 branch is customised for qt5 Beta ONLY. You also need to have a video card/ video chip in your PC that is opengl 2.0 compatible for it to compile and run.

===Aug 3 2012===
glSDR updated to version 6. This has Rx IQ Correction setting in the DSP tab. You should enable it only when connecting to servers running IQ based hardware (eg Softrock, UHFSDR), but NOT direct sampling rigs (eg Perseus).

===July 3 2012===
Experimental version of glSDR (version 5) that has Tx capabilities. Will only work in certain devices capable of 8khz microphone audio recording and fast CPU at the moment. Go to MENU > Tx to enable tx. Will only work with servers allowing anyone to Tx. http://code.google.com/p/sdr-widget/downloads/detail?name=glSDR.apk&can=2&q=

===May 30 2012===
The opengl ES 2.0 enabled version of the Android client has been uploaded to Google Play store and can be downloaded to compatible Android devices. The name of the App is glSDR.

===May 28 2012===
Tx audio encoding now has two available codecs: aLaw and Codec2. aLaw uses higher LAN bandwidth but the audio quality is much better than Codec2. aLaw is also suitable for digital mode Tx using the fldigi front-end connected to QtRadio. The Tx code is available in both the master and the opengl-qt5 branches.

===May 19 2012===
Qt5 has the bug fix for pull mode audio in Qt. The master branch and the opengl-qt5 branch can be built with the latest Qt5 (BETA) daily snapshot and the audio in pull mode works very well with Ubuntu 12.04 where most users had problems.

===May 12 2012===
Experimental support for [[RTL-SDR]] available.

===Apr 11 2012===
* The branch audio-testing was created for linux users who were having trouble with Qt's lack of sound in QtRadio. It seemed to be more of a problem with newer 64 bit installs. audio-testing bypasses QT for audio playback and calls pulse audio libs directly. You may have to direct sound to your proper sound device with pavucontrol.

===Apr 5 2012===
* Created an article on the Utilities & Add-ons page called: "Full featured recording script" unsing sox and rigctl (hamlib).

===Apr 4 2012===
* A new branch, opengl, has working QtRadio code that uses OpenGL shaders to compute and display the waterfall. The waterfall is actually a 3-D cube and you can pan/zoom with mouse drags on the waterfall display. Drag it all the way to one side and you can have a glimpse of the sides of the cube. The aim of this QtRadio is to offload work from the cpu to the gpu. If your system has a weak cpu (eg atom) and a powerful gpu (eg nvidia ION) it should reduce the cpu util significantly.

===Mar 18 2012===
* A new build for windows from the new protocol-3 branch is available at: http://napan.com/ve9gj/qtradio-protocol-3.zip (Built Mar 18 2012). This uses the new protocol-3 and should be able to connect with master and protocol-3 servers. Still experimental. It contains improvements to the spectrum and waterfall refresh rates for remote connections.

===Feb 25 2012===
* New Windows build of QtRadio (master branch) Download: http://napan.com/ve9gj/qtradio-master.zip
===Feb 19 2012===
* Graeme ZL2APV has coded CW receive in QtRadio to behave the same as Kenwood, Yaesu, K3 etc.
===Feb 18 2012===
* Frank DG1SBG has got QtRadio to run on Mac OS X 10.6.8 ! http://www.youtube.com/watch?v=LaWnr6Pn3ek
===Feb 17 2012===
* Bugfix to possible segfault in dspserver
===Feb 16 2012===
* New Windows build of QtRadio (master branch) Download: http://napan.com/ve9gj/qtradio-master.zip
===Feb 11 2012===
* The android client AHPSDR now has a Server list feature just like QtRadio. Look under the menu item Servers and select from among the active servers Download information on the [[AHPSDR]] page
* The branch to use for most users is now the master branch. This is the one that most dspservers are running
* Fixed SetTXAMCarrierLevel bug when tx ="all" in master branch
* Two key Rx audio functions into their own QThread in QtRadio. This should help lower spec'd PCs
* Fixed a bug where the band edge line in the spectrum display was off by the offset value of the dspserver.

The zoom feature has been ported to glSDR. Ver 9 is now in Play store. For those without access to Play store, you can download the apk here:

http://code.google.com/p/sdr-widget/downloads/detail?name=glSDR9.apk&can=2&q=

With the recent changes, high bandwidth rigs are now adequately supported by ghpsdr3-alex. You can zoom in and out to spectrum/waterfall up to 960 ksps and beyond.

Note that Glenn has also compiled a Windows binary of QtRadio that has the zoom feature and other updates to allow you to access rigs such as HiQSDR and Perseus. allowing you to set Pre-selector, attentuator etc.

===Sep 10 2012===
The LO_offset mechanism has been revamped. The rotation of the spectrum data is now done entirely in dspserver. Therefore clients eg. QtRadio, glSDR, do not have to rotate the data anymore.

This is needed to support the new zoom feature. You can now zoom the spectrum/waterfall on the fly. This feature is very useful for looking closely at a signal, eg 50Hz CW for you to tune spot on, and also for very wide bandwidth hardware such as Peuseus and HiQSDR. We now have servers running 500 ksps or even 960 ksps.

http://code.google.com/p/sdr-widget/downloads/detail?name=g3vbv2.ogv&can=2&q=

It will take a while for all dspservers to be updated to the lastest code and you must use the latest QtRadio and glSDR (ver 8 or later) for the new LO_offset.

===Sep 5 2012===

Just to summarise the status of support of the just released Qt5 Beta1 for building QtRadio under Linux:

1. You download and install the Qt5 Beta:

http://releases.qt-project.org/qt5.0/beta1/

2. You set the path to point to the qmake you want to use:

$ export PATH=/where/the/Qt/bin/dir/is:$PATH

(For example, mine is:

export PATH=/home/alex/Qt5.0.0beta1/Desktop/Qt/5.0.0-beta1/gcc_64/bin:$PATH

)

3. You can check which version of Qt is active by:

$ qmake --version

(For example, mine is:

alex@alex-Aspire-4750:~/ghpsdr3-alex$ qmake --version
QMake version 2.01a
Using Qt version 5.0.0 in /home/alex/Qt5.0.0beta1/Desktop/Qt/5.0.0-beta1/gcc_64/lib

)

4. The master branch now has conditional compile for Qt5 Beta and for older versions of Qt. Once the above PATH is set for the version of Qt you want, you can just use the usual automake steps to build.

5. The opengl-qt5 branch is customised for qt5 Beta ONLY. You also need to have a video card/ video chip in your PC that is opengl 2.0 compatible for it to compile and run.

===Aug 3 2012===
glSDR updated to version 6. This has Rx IQ Correction setting in the DSP tab. You should enable it only when connecting to servers running IQ based hardware (eg Softrock, UHFSDR), but NOT direct sampling rigs (eg Perseus).

===July 3 2012===
Experimental version of glSDR (version 5) that has Tx capabilities. Will only work in certain devices capable of 8khz microphone audio recording and fast CPU at the moment. Go to MENU > Tx to enable tx. Will only work with servers allowing anyone to Tx. http://code.google.com/p/sdr-widget/downloads/detail?name=glSDR.apk&can=2&q=

===May 30 2012===
The opengl ES 2.0 enabled version of the Android client has been uploaded to Google Play store and can be downloaded to compatible Android devices. The name of the App is glSDR.

===May 28 2012===
Tx audio encoding now has two available codecs: aLaw and Codec2. aLaw uses higher LAN bandwidth but the audio quality is much better than Codec2. aLaw is also suitable for digital mode Tx using the fldigi front-end connected to QtRadio. The Tx code is available in both the master and the opengl-qt5 branches.

===May 19 2012===
Qt5 has the bug fix for pull mode audio in Qt. The master branch and the opengl-qt5 branch can be built with the latest Qt5 (BETA) daily snapshot and the audio in pull mode works very well with Ubuntu 12.04 where most users had problems.

===May 12 2012===
Experimental support for [[RTL-SDR]] available.

===Apr 11 2012===
* The branch audio-testing was created for linux users who were having trouble with Qt's lack of sound in QtRadio. It seemed to be more of a problem with newer 64 bit installs. audio-testing bypasses QT for audio playback and calls pulse audio libs directly. You may have to direct sound to your proper sound device with pavucontrol.

===Apr 5 2012===
* Created an article on the Utilities & Add-ons page called: "Full featured recording script" unsing sox and rigctl (hamlib).

===Apr 4 2012===
* A new branch, opengl, has working QtRadio code that uses OpenGL shaders to compute and display the waterfall. The waterfall is actually a 3-D cube and you can pan/zoom with mouse drags on the waterfall display. Drag it all the way to one side and you can have a glimpse of the sides of the cube. The aim of this QtRadio is to offload work from the cpu to the gpu. If your system has a weak cpu (eg atom) and a powerful gpu (eg nvidia ION) it should reduce the cpu util significantly.

===Mar 18 2012===
* A new build for windows from the new protocol-3 branch is available at: http://napan.com/ve9gj/qtradio-protocol-3.zip (Built Mar 18 2012). This uses the new protocol-3 and should be able to connect with master and protocol-3 servers. Still experimental. It contains improvements to the spectrum and waterfall refresh rates for remote connections.

===Feb 25 2012===
* New Windows build of QtRadio (master branch) Download: http://napan.com/ve9gj/qtradio-master.zip
===Feb 19 2012===
* Graeme ZL2APV has coded CW receive in QtRadio to behave the same as Kenwood, Yaesu, K3 etc.
===Feb 18 2012===
* Frank DG1SBG has got QtRadio to run on Mac OS X 10.6.8 ! http://www.youtube.com/watch?v=LaWnr6Pn3ek

--------------------------

'''Set up a programming environment for aHPSDR'''

Install Eclipse -I chose the "Eclipse Classic 3.7.x" and got it here: <http://www.eclipse.org/downloads/>

Download and set up the Android SDK and ADT plugins for Eclipse by following the instructions located here: <http://developer.android.com/sdk/installing.html>

You may also need to install Java. See the instruction at the bottom of the above link.

Once all above is installed start Eclipse and go to the menu / Window and select the "Android SDK Manager" Here you add the API packages for the target Android platform(s.)

John Melton's aHPSDR is currently written for Android 2.2, API level 8. Be sure to check the top level box for API level 8. It should also run well under API level 7 if your device is 2.1. You may have to adjust the properties to get it to build, though.

Unless you want to tackle rewriting the application for a higher API level, you really don't need to download any of the higher levels, although it wont hurt anything.

You can also install an android device simulator. You can bypass this step if you would rather test the .apk directly on your USB connected device. The simulators are quite slow and require patience when they initialize. The aHPSDR program runs slow and choppy as well (at least on my box -YMMV). You can set up the simulator from the Menu/ Window / AVD manager

Get the aHPSDR sources from: svn co http://svn.tapr.org/repos_sdr_hpsdr/trunk/N6LYT/ghpsdr3/branches/android/ This will create a folder named android in you home directory.

To get started create a new project: File / New / Project. From the select a Wizard window select Android / Android Project then click Next>

Give your project a new name then click Create project from existing source Then Browse to the location the sources are located home/android/aHPSDR then click Next.
Select the target platform/API, Select Android 2.2 (Platform 2.2 API Level 8) then click Finish.

You will now see your new project in the Package Explorer window on the left. Select it then from the Menu Run/ Run. When the window opens select run as android application then click OK

Wait for the ADP simulator to initialize ( could take several minutes and you will have to unlock, etc just like the real device. ) Go to the applications on the device and select aHPSDR.

Have fun!

73, Kevin

* If you rebuild aHPSDR for 2.3.3 and when you are using Android 2.3, the performance is improved a lot over the one built for 2.1, so following Kevin's instructions is better than just installing the default aHPSDR.apk with (from the platform-tools directory
./adb install aHPSDR.apk

Alexlee188: /* Dec 20 2012 */

===Dec 25 2012===
I have made updating info in dspserver.conf compulsory instead of optional. There are far too many "UNKNOWN" new stations online.

I have updated opengl branch with version 29 of glSDR:

http://code.google.com/p/sdr-widget/downloads/detail?name=glSDR29.apk&can=2&q=

===Dec 20 2012===
Qt5 final is here:

http://qt-project.org/downloads

Download it and install in /opt/Qt5.0.0 (use sudo when running the installer).

Then set the path with something like:

$ export PATH=/opt/Qt5.0.0/5.0.0/gcc_64/bin:/opt/Qt5.0.0/Tools/QtCreator/bin:$PATH

The git repo branches iw0hdv, master and opengl have been updated to build with Qt5 final (and so they are incompatible with older versions of Qt5 such as the BETA or from the Edgers repo etc).

===Nov 26 2012===
glSDR version 28 is in Google Play and is also available for download.

Added direct support in QtRadio (linux) for the Griffin Powermate Vfo knob. Pushing the knob cycles through vfo step size.

===Sep 15 2012===

Codec2 has been updated to the latest developmental branch. This branch can be downloaded:

svn co https://freetel.svn.sourceforge.net/svnroot/freetel/codec2-dev codec2-dev

This has a new API and it has updated codec2, including a new 3200 bps codec which gives better quality than the 2400 bps codec we have used in the past.

Both master and opengl-qt5 branches have been updated with the new codec2. You need to download the codec2-dev branch above, rebuild codec2, and then rebuild dspserver and QtRadio.

===Sep 14 2012===

This feature is very useful for looking closely at a signal, eg 50Hz CW for you to tune spot on, and also for very wide bandwidth hardware such as Peuseus and HiQSDR. We now have servers running 500 ksps or even 960 ksps.

It will take a while for all dspservers to be updated to the lastest code and you must use the latest QtRadio and glSDR (ver 8 or later) for the new LO_offset.

Just to summarise the status of support of the just released Qt5 Beta1 for building QtRadio under Linux:

1. You download and install the Qt5 Beta:

http://releases.qt-project.org/qt5.0/beta1/

2. You set the path to point to the qmake you want to use:

$ export PATH=/where/the/Qt/bin/dir/is:$PATH

(For example, mine is:

export PATH=/home/alex/Qt5.0.0beta1/Desktop/Qt/5.0.0-beta1/gcc_64/bin:$PATH

)

3. You can check which version of Qt is active by:

$ qmake --version

(For example, mine is:

alex@alex-Aspire-4750:~/ghpsdr3-alex$ qmake --version
QMake version 2.01a
Using Qt version 5.0.0 in /home/alex/Qt5.0.0beta1/Desktop/Qt/5.0.0-beta1/gcc_64/lib

)

4. The master branch now has conditional compile for Qt5 Beta and for older versions of Qt. Once the above PATH is set for the version of Qt you want, you can just use the usual automake steps to build.

5. The opengl-qt5 branch is customised for qt5 Beta ONLY. You also need to have a video card/ video chip in your PC that is opengl 2.0 compatible for it to compile and run.

glSDR updated to version 6. This has Rx IQ Correction setting in the DSP tab. You should enable it only when connecting to servers running IQ based hardware (eg Softrock, UHFSDR), but NOT direct sampling rigs (eg Perseus).

===July 3 2012===
Experimental version of glSDR (version 5) that has Tx capabilities. Will only work in certain devices capable of 8khz microphone audio recording and fast CPU at the moment. Go to MENU > Tx to enable tx. Will only work with servers allowing anyone to Tx. http://code.google.com/p/sdr-widget/downloads/detail?name=glSDR.apk&can=2&q=

===May 30 2012===
The opengl ES 2.0 enabled version of the Android client has been uploaded to Google Play store and can be downloaded to compatible Android devices. The name of the App is glSDR.

===May 28 2012===
Tx audio encoding now has two available codecs: aLaw and Codec2. aLaw uses higher LAN bandwidth but the audio quality is much better than Codec2. aLaw is also suitable for digital mode Tx using the fldigi front-end connected to QtRadio. The Tx code is available in both the master and the opengl-qt5 branches.

===May 19 2012===
Qt5 has the bug fix for pull mode audio in Qt. The master branch and the opengl-qt5 branch can be built with the latest Qt5 (BETA) daily snapshot and the audio in pull mode works very well with Ubuntu 12.04 where most users had problems.

===May 12 2012===
Experimental support for [[RTL-SDR]] available.

* The branch audio-testing was created for linux users who were having trouble with Qt's lack of sound in QtRadio. It seemed to be more of a problem with newer 64 bit installs. audio-testing bypasses QT for audio playback and calls pulse audio libs directly. You may have to direct sound to your proper sound device with pavucontrol.

===Apr 5 2012===
* Created an article on the Utilities & Add-ons page called: "Full featured recording script" unsing sox and rigctl (hamlib).

===Apr 4 2012===
* A new branch, opengl, has working QtRadio code that uses OpenGL shaders to compute and display the waterfall. The waterfall is actually a 3-D cube and you can pan/zoom with mouse drags on the waterfall display. Drag it all the way to one side and you can have a glimpse of the sides of the cube. The aim of this QtRadio is to offload work from the cpu to the gpu. If your system has a weak cpu (eg atom) and a powerful gpu (eg nvidia ION) it should reduce the cpu util significantly.

===Mar 18 2012===
* A new build for windows from the new protocol-3 branch is available at: http://napan.com/ve9gj/qtradio-protocol-3.zip (Built Mar 18 2012). This uses the new protocol-3 and should be able to connect with master and protocol-3 servers. Still experimental. It contains improvements to the spectrum and waterfall refresh rates for remote connections.

* The android client AHPSDR now has a Server list feature just like QtRadio. Look under the menu item Servers and select from among the active servers Download information on the [[AHPSDR]] page
* The branch to use for most users is now the master branch. This is the one that most dspservers are running
* Fixed SetTXAMCarrierLevel bug when tx ="all" in master branch
* Two key Rx audio functions into their own QThread in QtRadio. This should help lower spec'd PCs
* Fixed a bug where the band edge line in the spectrum display was off by the offset value of the dspserver.
