Hi The G8JCFSDR V 1.0.284, aka "Build 284" is available for Download & Install. What’s new in Build 284 ? Windows XP Compatibility Build 284 restores Windows XP compatibility. I think I inadvertently broke XP compatibility in Build 280 – apologies to all those running Windows XP. Linux + Wine Compatibility Build 284 brings the G8JCFSDR to the Linux + Wine environment in a straightforward to install manner, ie as close to the Windows install process/experience as possible. I only have Ubuntu, Debian and Mint environments, so users with other environments who can test things out would be most welcome. New Installer Technology Since its first release, the G8JCFSDR has used InstallShield Express V3.5 SP4 installer technology from back in 2001 !! Express is getting very long in the tooth, and just does not work properly under Windows 10. Express had worked properly on every OS upto and including Windows 7, but W10 broke it, (I used a W7 VM under W10 to carry on building the installer packages, but it was getting quite tedious shipping files into the W7 VM whenever a change was made. Anyway, I have finally bitten the bullet and summoned up the courage to try something different and upto date, driven by the W10 problem, and the need for something a lot more flexible to deal with the needs of the Linux + Wine environment, so I settled on INNO setup (with PERL scripting handling the LINUX specific bits). I would also like to know that the new installer works properly, and of course that means “guinea pigs” aka field testers please !! Any problems, suggestions for improvements would be most gratefully received. The G8JCFSDR Build 284 has been tested under Mint 19.3 Tricia with Wine 4.0 (32 bit) Mint 20 Ulyana with Wine 5.0 (64bit) Debian Bookworm 64bit with Wine+Box64 - use Pi-Apps to install Wine, Box64 and all their dependancies The setup program may be downloaded from https://www.g8jcf.uk/g8jcfsdr_drt1/downloads/setup_G8JCFSDR_284.exe On a windows machine just install the G8JCFSDR with a double-click, ie just like you would for any setup.exe. On a Linux + Wine system, you may find that you need to open up a terminal session cd ~/Downloads #or wherever you have downloaded the setup program to then type wine setup_G8JCFSDR_284.exe and follow the on-screen instructions. I have attached the Linux + Wine section of the G8JCFSDR User Guide covering installation on Linux + Wine systems, NB the instructions refer to COM1 but the script will in fact use COM16 (I need to update the User Guide) which is a highly unlikely COM port mapping - the majority of Windows programs can only deal with COM1 - COM4, so a 'collision' with an existing wine COM port mapping should be highly unlikely. The only difference between the Windows install process and the Linux + Wine process is that an additional pre-install step will be displayed before the traditional (for Windows) gui installer kicks in. Any suggestions for improvements, problems, bug reports, would be most appreciated. Many Thanks & 73 Peter - GM8JCF

Hi I've just got the G8JCFSDR working completely properly on a Raspberry Pi 4 running Buster - see Screenshot - :-) Before you install wine etc, you need to make sure that you have a proper working and configured ALSA audio system on your RPI. The RPI doesn't have an onboard soundcard so an external USB soundcard is required, I used an ASUS XONAR 7, but I have also managed to get a Creative X-Fi working, but it was nowhere as easy as the ASUS XONAR. Once you have got a correctly working audio setup, you can proceed to installing wine, g8jcfsdr etc, ie there's no point in trying wine etc until there is a working LINUX ALSA setup. The "secret sauce" to making wine(x86) work consistenly on my RPI was to use pi-apps, https://pi-apps.io , wget -qO- https://raw.githubusercontent.com/Botspot/pi-apps/master/install | bash installs pi-apps itself, then run pi-apps and install wine(x86). The pi-apps way of installing wine(x86) will install box86 and a whole load of dependencies, dlls, and other vital stuff in addition to wine itself. I had tried the more usual methods of installing wine(x86) on the rpi manually, but it was always hit or miss if things worked properly, but with the pi-apps method it just works !! If you use the usual sudo apt install wine method, you will install wine(armhf) which will only run Windows programs written for ARM processors which is not what is needed here, and indeed there are very few Windows programs compiled for ARM afaik. After pi-apps has finished - it took at least 15 mins for me over 12 Mbit DSL - the first thing to do is set the sound configuration for wine to ALSA using either the winetricks gui or in a terminal type winetricks settings sound=alsa For some reason the default sound setting for wine is pulseaudio which just doesn't work for pretty much anything - rant over, it took me 4 hrs to figure out why nothing seemed to work - audio wise - under wine Then download the G8JCFSDR setup from https://www.g8jcf.uk/g8jcfsdr_drt1/downloads/setup_G8JCFSDR_284.exe This build has support for LINUX based environments. Run the setup program and follow the onscreen instructions. The main difference between the standard Windows installer and the LINUX installer is the addition of a step to add the user to the dialout group - required for access to serial ports, and then mapping LINUX serial ports, eg /dev/tty0 to wine COM ports, eg com16, after that the standard windows installer is run. Once the installer has finished, you should be able to run the G8JCFSDR and do all the usual stuff to configure, calibrate and other actions just as you would for a windows environment. My next step is to get a small 7 in TFT touch screen for my rpi, and box it all up to make a standalone small communications receiver - complete with proper tuning knob !! I would be interested if someone else can give this setup a tryout and let me know if it works for them - btw this should also work on an RPI 3B+ 73 Peter - GM8JCF

Hi Windows 10, starting with build 1903, provides the option to disable access to your Microphone to desktop applications, use Winkey+I, Privacy, Microphone, then scroll down in the RHS pane until you see "Allow desktop apps to access your microphone", Despite the description of "Microphone", this setting also affects the "Line" input which is used for I/Q input to the G8JCFSDR. If this setting is set to *OFF* , then when U click the power on button in the G8JCFSDR U will get the dreaded Run-time error '-2147467259 (80004005)' message, and yet all the usual diagnostic tests, eg DXDiag.exe will say that your audio device(s) is/are working correctly. I recently worked with John Coulter - thank you John - to track down why he was getting this error message despite all the signs that his PC's h/w was working correctly and we finally tracked down the problem to this "new and improved" privacy setting ! So please make sure that you have "Allow desktop apps to access your microphonr" set to *ON*. 73 Peter

Hi, Peter, the actual built 282 of G8JCF softwareradio under WIN10 (64bit) is not able to load the corresponding firmware into the elektor SDR Shield 2.0. (failure after 14%) . Where i can find the XLoader and the Arduino Uno hexfile for Build 282? Ulf DL3KS -- Mit freundlichen Grü?en, best regards, Dipl.-Ing.

I have found a bug inside this build 284 ! May be, the bug persists also inside earlier builds (please check) ! The bug is the capital letter -M inside DREAM Prog Args : Caused by this bug DREAM V2.2.1 is not able to start automatic on selected DRM mode! Peter, please fix this bug quickly or make the default args changable! Please check the autostart with DREAM V2.2.1 ! Thank You for effort, -- Mit freundlichen Grü?en, best regards, Dipl.-Ing.

Here comes all actual DREAM commands, big letter -M is not supported! So the fixed prog args line in Build 284 is failed and DREAM can not automatic start -- Mit freundlichen Grü?en, best regards, Dipl.-Ing.

Hi Massimo's recent post about his problem with the G8JCFSDR &Windows 11 got me thinking, and since I didn't have any kind of Windows 11 machine at all, I went looking for the cheapest way of obtaining a W11 system, and came across this Lenovo IdeaPad 1i 11.6in Celeron 4GB 64GB Laptop, https://www.argos.co.uk/product/1237384?istCompanyId=a74d8886-5df9-4baa-b776-166b3bf9111c&istFeedId=30f62ea9-9626-4cac-97c8-9ff3921f8558&istItemId=riawaxlpt&istBid=t&&cmpid=GS001&_$ja=tsid:59157%7cacid:804-627-9544%7ccid:16595965133%7cagid:138274018207%7ctid:pla-872033623866%7ccrid:588246381293%7cnw:u%7crnd:7882888430970232170%7cdvc:c%7cadp:%7cmt:%7cloc:9046847&utm_source=Google&utm_medium=cpc&utm_campaign=16595965133&utm_term=1237384&utm_content=shopping&utm_custom1=138274018207&utm_custom2=804-627-9544&GPDP=true&gclid=Cj0KCQiA1ZGcBhCoARIsAGQ0kkqxxWpMDTSzNqjOcEjrRkiHnjSriZuixeVNApwr3wOCs3e1N-Y59zMaAlcEEALw_wcB&gclsrc=aw.ds for just under GBP 100 which seemed to be a great bargain. Anyway, I went off to the shop and bought one last Thursday. For GBP 100 I wasn't expecting much, but Lenovo is a good brand and makes some very serious kit (they used to supply IBM with laptops etc until IBM pulled out of the PC market and sold everything to Lenovo), and indeed this laptop all plastic, so it doesn't have the feel or looks of more expensive laptops, but once I had removed the "S" part of Windows S, I now had a fully functioning Windows 11 Home Edition machine which meant that I could install the G8JCFSDR from https://www.g8jcf.uk/g8jcfsdr_drt1/downloads/setup_G8JCFSDR_282.exe (the G8JCFSDR has an installed footprint of less than 21MBytes, so the 64GB C: is barely troubled), which went as expected without any errors. I then fired up the G8JCFSDR and it started up again as expected :-) Now I have to conduct some full testing with a variety of different SDR H/W front-ends, eg PMSDR, DRT1, Elektor SDR Reloaded etc, but it's all looking very promising. I don't know if this is relevant to my experience, but I resisted all of Microsoft's attempts to get me to sign in with my Microsoft Account (U have to agree to use your online account initially to get into the machine, but once you're in you can then create local accounts, sign-out of the online account, sign in using the local account, and then delete the online account), so when I'm logged into W11, I am NOT logged into Microsoft at the same time, however hard they try to get you to go online with them !!! Anyway, I hope this post helps someone, and I will report back soon with more information on the tests - I would have carried out more tests over the weekend, but the FIFA World Cup is on, and with 4 matches a day .... :-) 73 Peter - GM8JCF

Hello, my dears! After a long break, I re-enabled the elektor labs SDR. Everything works fine on the PC, but I want it as a stand-alone. My question to the group: Has anyone ever operated the SDR with an lcd, as in the photo? If there is already an Arduino software for it, I don't have to break my fingers programming it myself :) Best greatings, Ralf - DK9PS -

Hi Peter and everyone in the group. I replace my old Pc, now I have a new machine with Win11. Try to install G8JFCSDR and arduino but when I switch on I receive this error: *Error @ Line=110438 (Object doesn't support this property or method) in procedure GetVer of Class Module clsElektorSDRShield* What happens? I didn't use software for a long time so I didn't remember the whole procedure to let it start. Help! Regards, Massimo

Hi,, All I hope I'm not mistaken into this group and I hope I don't divert the core topic in this group. My previous SDR Shield Elektor project was using G8JCFSDR, HDSDR and PowerSDR software. My current SDR Shield Elektor project is using some of the PE1NNZ QCX-SSB firmware. I compiled and uploaded the firmware using the Arduino IDE and Arduino UNO board. The end goal is to assemble the SDR Shield Elector into a portable TRX that is no longer connected to a PC. This project is not perfect but: using a 40 meter band open dipole antenna (10 meters high), I was able to report reception of 59 to LSB communication (40 Watt) which is about 1500km from my location. I will be very grateful if any of you develop and share this project. 73, YB2RR Yoyos

Hi, I am trying to get my Elektor SDR to work with my Arduino Mega2560. I have run the program as administrator and followed the advice in previous topics. I have used Xloader to install "../arduinocode/si5351vfoGM8JCF.hex" onto the board. However, when I turn the board on, I still get the popup saying the firmware needs to be updated with the following result: I have verified that I am using Com7 for the Arduino. Thanks for the help in advance! Reed

Hi, when starting the program I get first the popup with the COM-port and then the popup with the text "modSetupRx.InitialiseRX..." (all this is described in the QuickStarter document). But then only the upper part of the program window is shown: and there is no possibility to enlarge the window (pulling the window frame edges is not possible). So, it's also not possible to change any parameter in the config, as the config button is not visible at all. I am using a Lenovo Laptop with Windows 10 and I have installed the build 282. The first lines of the log file (starting the program in trace-mode) looks like: G8JCFSDR Log File started at 2022-03-29 19:16:31 Log file=C:\Users\marku\AppData\Local\Temp\G8JCFSDR.log 0:00:00:031 frmSupervisor.Initialise : Windows Version=Windows 10 (v10.0.19042) 0:00:00:062 frmSupervisor.Initialise : Working Directory=C:\Program Files (x86)\G8JCF\G8JCFSDR 0:00:00:062 frmSupervisor.Initialise : app.Path=C:\Program Files (x86)\G8JCF\G8JCFSDR 0:00:00:062 frmSupervisor.Initialise : app.EXEName=G8JCFSDR 0:00:00:078 frmSupervisor.Initialise : app.Major=1 0:00:00:078 frmSupervisor.Initialise : app.Minor=0 0:00:00:078 frmSupervisor.Initialise : app.Revision=282 0:00:00:094 frmSupervisor.Initialise : Start 0:00:00:094 frmSupervisor.Initialise : Initialising Constants 0:00:00:094 frmSupervisor.Initialise : Initialising Objects If it is needed I can provide the complete log file, of course.
