Re: [Flexradio] F5K & F3K & Android 3.1
I developed an Android client for my HPSDR software (currently receive only). I have it running on both my Android phone and a 7" tablet. There is a (not very good) video of a very early version running on an HTC Magic phone and some more information on my blog at http://g0orx.blogspot.com/2010_02_14_archive.html I have a server running that does all the DSP work using DttSP. The audio is streamed as uLaw 8 bit samples at 8k samples/second. The spectrum data is sent as a sequence of unsigned bytes which are interpreted as 0 to -255 dBm for the spectrum and waterfall displays. The client requests the number of samples for each frame based on the display width and the server does the averaging. Running with a refresh rate of 10 frames per second on a display of 800 pixels width only requires 8000 bytes/second. Combined the spectrum and audio data require about 16kB per second. The frequency can be changed by dragging the spectrum/waterfall display or by using a thumb wheel if present. Bands and other options such as mode, filter, etc are selected using menus. I did have this running in Dayton (2010) on my phone connecting back to my server in the UK and was able to listen to the Formula 1 Grand Prix commentary on BBC Radio 5 on 909kHz with no problems. -- John g0orx/n6lyt On Mon, 2011-07-25 at 19:32 +, Jack Haverty. wrote: > Hi Ross, > > That's a good article.

Re: [Flexradio] iphone sdr
I have been playing with the iPhone and HPSDR. I modified my ghpsdr linux software to listen on a TCP port where it accepts commands to set frequency and band. It sends spectrum data and the audio stream to the iPhone. You can see some early screen shots and video in my blog at http://javaguifordttsp.blogspot.com/2009/07/iphone.html and http://javaguifordttsp.blogspot.com/2009/07/iphone-video-running-on-simulator.html I have not released any source code yet for the this, but if anyone is interested in developing this further then I would be happy to share. I did pay the license fee to be able to load the software onto my iPhone. I have used it while walking around the house to monitor the bands ;-) Regards, John g0orx/n6lyt On 10/18/09 00:51, Clay W7CE wrote: Since I bought an iPhone this summer, I've been thinking a lot about using it with PowerSDR. Personally, I'm not interested in jailbreaking the iPhone and voiding the warranty. What I am considering instead is modifying PowerSDR to include VOIP and remote control by TCP/IP. Properly done, PowerSDR could be used locally from your computer or be configured to listen for incoming connections from another copy of PowerSDR running in remote mode. With this capability in place, it would then be possible to write an iPhone app that handles the control and voice functions for remote station usage. I spend a fair amount of time on the road and would have access to my station from my iPhone during the day and from my laptop at night. I don't think it could get much better than that.

Re: [Flexradio] iMac user thinking about purchasing SDR1000
Hi Dan, several people have run PowerSDR using Parallels on the Mac (www.parallels.com). If you look at the mailing list archive you should be able to find some info on this. I have been working on a Java GUI that uses sdr-core (the DSP code) that runs native on the Mac and Linux. I have it running on a MacBook Pro with 2GB of memory. It is receive only while we work some problems with the transmit side. It connects to the SDR-1000 using the USB cable from Flex Radio. For receive the built in sound card on the mac is good at 96000. I also have an Edirol FA-66 which can run up to 192000 with no problems and works great on transmit.

Re: [Flexradio] Java GUI for SDR-1000
I mistakenly put a version of the sdr1000 hardware code that did not support parallel ports. I have updated it on java.net so you should be able to do an 'svn update' from within the java-sdr directory and it will update the binary. I have only been using the USB cable, so that one slipped through. The jack output implies that you already have jackd running! Also jackd is being started with -dhw:1 do you know if that is the correct device? If it is the only sound card in your system you would need to change the configuration entry from -dhw:1 to -dhw:0. -- John g0orx/n6lyt José Dumoulin wrote: > Sorry...

[Flexradio] Java GUI for SDR-1000
I have created a Subversion repository at http://java-sdr.dev.java.net with the source code for Java GUI for the SDR-1000.

Re: [Flexradio] I am a programmer
Jon, The current DSP code is written in C. On Windows it is a DLL but on Linux and Mac OS X it runs as a process called sdr-core. The interface to the Linux and Mac OS X DSP code is through fifos, which is basically an in memory file, also known in the Unix world as a named pipe. Each sdr-core has 3 fifos. The first one is the command fifo for the controlling program to send commands to the DSP code, such as 'setFilter 150 2250' to set an 2.1KHz filter with a 150 Hz offset and 'setMode 1' to set the mode to USB. The second one is the Spectrum fifo which the DSP code writes to whenever it processes a 'reqSpectrum' command written to the command fifo. The data written to the Spectrum fifo is used to create the various displays such as the Panadapter. The third one is the Meter fifo which the DSP code writes to whenever it processes a 'reqMeter' command written to the command fifo. The data written to the Meter fifo is used to display the various meter functions. Any language that can read and write to a file can be used to write a controlling program (GUI). I have written code in both Java and C to this interface. Hope that helps. Regards, John g0orx/n6lyt K6JEK wrote: > I am a programmer.

Re: [Flexradio] I'm not a programmer
To get an idea of the GUI for the SDR-1000 take a look at my new Blog at http://javaguifordttsp.blogspot.com/ Any similarities to PowerSDR are intentional ;-) I have put a couple of screen shots of it running on the Mac which includes the Activity Monitor to get an idea of the memory utilization and the CPU utilization. The version of DttSP (sdr-core) that it is running is the dttsp-ng version pre the 48000 down sampling changes.

Re: [Flexradio] Mac Computers.
I have been working on a GUI written in Java (that is nearly finished) for the SDR-1000 that runs on Linux and Mac OS X using DttSP and the hardware interface code for the SDR-1000. It works with both parallel and USB interfaces on Linux and the USB interface on the Mac. The ultimate goal is to get the hardware interface code to talk to both the SDR-1000 and the 5000. I have not looked at the audio interface for the 5000, but I am sure Frank and Bob know what to do in that area. regards, John g0orx/n6lyt Richard Beerman wrote: > I absolutely second this idea of running Mac OS X in conjunction with the > Flex radio system.

Re: [Flexradio] XML
It would be very useful to have an SDR1000/SDR5000 DTD defined. I am saving the state in my Java GUI as an XML file and it would be really great to be able to use and/or exchange this with other software applications. My original code had all the state information maintained in State class which I was serializing to an XML file. Worked OK on Linux but I found a problem with the implementation of the Mac OS X Java 5.0.+ where it would not serialize Enum objects, so I have had to put all the state into a Property object and write that out as an XML file.

Hi Iñigo, you should join the dttsp-linux yahoo group. The DttSP code for linux compiles and runs on OsX (at least the MacBook Pro that I have which is an Intel architecture). I am currently working on a GUI written in Java that runs on both Linux and OsX for the SDR-1000.

Re: [Flexradio] One Shoe Will Not Fit All
I have now implemented 2 (VERY) prototype GUIs running on Linux with DttSP2. http://microsat.homelinux.org/dttsp/gsdr http://microsat.homelinux.org/dttsp/gbeppe gsdr implements the look and feel of PowerSDR and gbeppe implements the look and feel of Beppe's design. In implementing both I am trying to abstract out the common code into a library so that the 'skin' designer just has to think about the look and feel and not all the underlying code necessary to support the interface to DttSP, and eventually the hardware, and manage state saving and restore and configuration information. What I want to get to is that when, for instance, a band is selected the skin code simply calls a function that will set everthing up correctly, including handling band stacking. However, it will be up to the skin code to decide how to modify the UI to show how it is shown that the band is selected (or deselected). Also there will need to be either a callback or a structure passed back to the GUI so that all the other displays/buttons related to the band change can be updated (i.e. mode, filter, etc). However, it should not be underestimated how much code is required to implement just the GUI portion of the code, but of course this could be helped by using a good IDE.

[Flexradio] Prototype GTK implementation of GUI design by Beppe IK3VIG
As part of a self learning project I have been playing with the GTK+ 2.0 toolkit using it to develop a GUI interface for the Linux DttSP code. I have spent some time trying to implement the GUI design that Beppe, IK3VIG, has proposed and now have something that I can share. It is still very much a prototype and not a lot has been implemented, but it is capable of tuning and decoding a signal using my various Softrock receivers. Details and a link for the compiled code and to Beppe's web page is available on my web site at: http://microsat.homelinux.org/dttsp/gbeppe regards, John g0orx/n6lyt ___ FlexRadio mailing list FlexRadio@flex-radio.biz http://mail.flex-radio.biz/mailman/listinfo/flexradio_flex-radio.biz Archive Link: http://www.mail-archive.com/flexradio%40flex-radio.biz/ FlexRadio Homepage: http://www.flex-radio.com
Re: [Flexradio] Linux - DttSP question: Commands to listen to AM radio?
Everett,
when it is running you should see that the alsa-pcm and sdr- are
cross connected if you bring up the Connections display in qjackctl (see
attached image).
You might also want to check that the line input is enabled on the sound
card and not the microphone input (I assume you are connected to the
line input).

Re: [Flexradio] Linux - DttSP question: Commands to listen to AM radio?
Hi Everett, you will need to use both the python script to control the parallel interface to select the band and the DDS frequency. You will need to use the cmdr script to control the jsdr software. To receive an AM signal you would need to send the following commands using the cmdr script: setRXOn 0 setSampleRate 96000 (or 48000 depending on your soundcard) setOsc 0 setFilter -3000 3000 setMode AM This is assuming that you do now want to offset the received frequency from the DDS frequency to move away from the noise at the 0 Hz IF. Hope that helps.

Re: [Flexradio] Linux Wishes
Hi Pete, As Dan says the software is available from my web site http://microsat.homelinux.org/dttsp/ (including source). It has been on hold for a while awaiting the new version of DttSP. Well, at least as far as releases go. I have added support for using with a Converter/Transverter on my development system. Currently there is no support for the transmit side. I plan on updating to work with the new version of DttSP and then get to work on transmit and controlling the SDR1000 hardware. I am also expecting an exciter card for the SoftRock series to be available soon that will need some support. -- John Melton Sun IT CTO Office: +44 1252 421708 (ext 21708) Mobile: +44 7714 708861 Dan Babcock wrote: > Hi Pete, > > I have used John's Java GUI for dttsp with my SoftRock v5.0 and a DDS-60 > VFO.

Re: [Flexradio] Linux distros
Jim Lux wrote: > I'm going to leap right into the middle of a religious war here.. I totally agree with Jim's ideas here and add my own thoughts. Currently, there is not a repository of binary images for the DttSP code and it's dependencies. It requires the user to download all the source code and possibly the source code for it's dependencies and build them on their own machine. What we need is a group of volunteers that will test the released binaries against their favourite distro and possibly rebuild them if there are any incompatabilies found and then put the binary packages in the repository for others to download. This should also include the required dependencies (currently jack, qjackctl, fftw). I would also like to point out that some of the small, easy to install, easy to use versions of Linux are usually not ideal for developing on. I installed Ubuntu on one of my machines (only requires 1 CD) and got very frustrated when it came to getting the development environment setup. The install had a Development option but it didn't even install gcc. I found I had to use Google to find out how to install it and then it required a command line 'sudo apt-get install build-essential' to get it installed. I had to repeat this for several packages that I would usually install with no problems on other distros. OK, once I finally did get it setup I was able to build and run DttSP (and my Java GUI). I should add that I have reverted back to Fedora (Core 5) ;-) I have seen an anouncement that Java 1.5 is now available on BSD 5.4 and 6.0! Anyone tried to get DttSP running on BSD?

Hi Stan, this is a common problem for a group that is distributed around the globe. No matter what time you pick someone is going to have an unsociable time. I really think the answer is to always have the meeting over a weekend and rotate the time for each meeting so that that it is not the same group that has the unsociable hours each time. Just my 2c worth.

Re: [Flexradio] comment on cost of development tools
Jim Lux wrote: But I'd venture to say that the open source alternative would take, perhaps 10 hours (by the time you download it, compile it for your particular environment, and get it up and running), and at $18/hr (roughly the average wage of employed people in the US), so you've just about come out the same. There ARE some almost "shrinkwrap" apps for Linux around, but even then, it's not always trouble free. I recenty had a disk crash and had to rebuild a PC that dual boots Windows XP and Linux (Fedora Core). It took me all day and into the evening to rebuid Windows by the time I had installed XP from CD along with Office and all the different drivers and then ran all the updates and fixes. And this did not include loading any development systems and rebuilding any code. It took 40 Minutes to install Fedora Core 4 plus another 45 minutes to download and build all the requirments for running DttSP (FFTW3, Jack, qjackctl, etc) and my Java GUI (J2SE 5). John g0orx/n6lyt

Hi Eric and all, what a great job you are doing with this software, thanks. I found a problem using Preview 3 with the SoftRock40.
