Hi, list, I've owned a DRT-1 back in 2007 and successfully used it together with the G8JCF-SDR-software. I sold it half a year later and was regretting that soon. When I found a cheap DRT-1 on ebay some months ago I bought it. Now here's my question: I have to admit I haven't read through each and every topic but is there a reason why no CW-mode has been implemented in the software. I am trying to listen to beacons in the NDB-band and if you are going to a very narrow bandwidth, AM is no longer usable. Any information appreciated. Thanks very much in advance. 73s Joachim

G8JCFSDR 281 on Linux Mint
5
Hello Peter I have installed G8JCFSDR 281 on Linux Mint DE4 with WINE for Elektor SDR-Shield2 and I have updated to Arduino via the terminal (si5351vfoGM8JCF.hex). My problem is that the program doesn't seem to work with Arduino because the serial port I have is / dev / ttyACM0 and not COM1. Is there a solution for this ??? Nikos Magafourakis SV9CVJ

Error about wrong port (3) but cannot change as the program does not run, so no way to configure it to the actual port number (14). Error message does not allow exit, keeps reappering until killed in process monitor.

Hi Peter, I am having some issues getting the software working using the ElektorSDRShield. O/S = windows10 Using arduino UNO, can control shield via arduino programs. xloader flashes arduino ok. Manual install works but does not give ElektorSDRShield as option and therefore no tuning options. Keep getting this message on full install. Sounds like one of my dll's is not up to date. Thanks, -- *Tom Mavroidis VE3ODH* *Toronto, Canada* *tmavroidis@... *

Hi The G8JCFSDR Build V 1.0 282 has been released, download from http://www.g8jcf.uk/index.htm Build 282 has many fixes and new features - see the QuickStartGuide ( http://www.g8jcf.uk/g8jcfsdr_drt1/downloads/QuickStartGuide.pdf ) for more details. *Higher IF sampling rates* 48000 48KHz spectrum display width 96000 96KHz spectrum display width 192000 192KHz spectrum display width 384000 384KHz spectrum display width assuming that your sound card can support these higher rates ¨C every soundcard I have used supports 48000, and most support 96000, with some supporting 192000, and very few (very expensive) supporting 384000. Note that the AF output sampling frequency is always 48000 samples/second enabling one to use the inbuilt soundcard and speaker(s) of your system whilst using a higher specification sound card to capture the IF output from the SDR down converter. *Synchronous AM Demodulation * SAM. SAM demodulation can be of help when fading, QSB, causes the AM carrier to almost disappear into the noise. Also, when there is adjacent channel interference. QRM, SAM can be useful to select the opposite sideband to the one being interfered with. SMD SAM Double Sideband, ie both sidebands used SMU SAM Upper Sideband SML SAM Lower Sideband *Additional Calibration Functionality* The SDRShield calibration window in Config has been augmented to provide additional functionality including an improved frequency calibration method. The IQ Cal Freq facility when switched on generates a carrier 1 KHz up from the current tuned frequency on CLK0 of the SI5351. If you have a V 2 SDRShield then attach a short length, eg 30cm, of wire to the CLK0 header pins. If you have a V1 SDRShield then very good soldering skills are required if you want to use this facility, ie not recommended. Follow the procedure for IQ balance/Image rejection described in 4.7. The SMeter Cal Freq when switched on generates a 10 KHz square wave on CLK2 of the SI5351 as described in Burkhard Kainka¡¯s book, 7.2, ¡°SDR Hands-on Book¡±. The output from CLK2 is 3V3 pk-pk or 1.65 V RMS. SMeter levels are measured in micro-volts, uV, so we use an attenuator (see below)), and the fact that square waves are rich in harmonics to generate signals in the uV range at HF. This arrangement will generate an S9 (50uV) signal at 7MHz, S8 at 14MHz, S7 at 28MHz. *Rotary Encoder Tuning, 1602 I2C LCD * Use a rotary encoder for real hardware/knob tuning, and optionally an LCD for frequency display. Connect a rotary encoder, eg ALPS EC16B2410408 RS 265-1723, A & B to pins 2 & 3 respectively and to OV. Connect a 1602 I2C LCD, eg https://hobbycomponents.com/displays/74-i2c-serial-lcd-1602-module or of course eBay, to pin A4(SDA) and pin A5(SCL), you will also need to connect Vcc and GND to the I2C LCD module of course. As always, all feedback would be most welcome 73 Peter - GM8JCf

Using a SDRplay RSP1A via the EXTIO TCP file
4
Dear all, Just getting started with this very nice software. Want to control my remote SDRplay RSP1A. I have the tcp extio server for this on a Raspberry Pi and can use it with HDSDR or SDRuno. But how can I select this extio file with G8JCFSDR. I find for instance a generic extio.dll as a choice in the drop down menu, but no config screen for this opens. Even though there is a very small E button saying : click to hide EXTIO GUI. So even when not remote, I would still need to set the extio rsp1a as a choice. What am I doing wrong? The last Manual has nothing on extio as far as I can tell. -- PE3ES / F4VTQ de Erwin

G8JCFSDR Build 280 Released
4
Hi The G8JCFSDR Build 280 is available for download from http://www/g8jcf.uk ( http://www.g8jcf.uk ). Build 280 is a minor improvement on Build 274, so if you are not experiencing any problems, there is no great benefit from installing build 280. The need for build 280 has arisen because some users are having problems uploading the .hex firmware into the Arduino Uno which controls the Elektor SDR Shield. Build 280 includes extra components which should eliminate this problem, specifically :- 1) libusb0.dll is now included into the ArduinoCode directory which should enable averdude.exe to function even when the Arduino IDE isn't installed. 2) The graphical utility *XLoader* is now installed along with the G8JCFSDR under the G8JCFSDR Start Menu entry so that one can manually upload the .hex firmware to the Arduino Uno. Some cosmetic changes have also been made to the G8JCFSDR Start Menu entries :- 1) Added Display QuickStartGuide shortcut 2) Added Display Readme shortcut 3) Added Display G8JCFSDR logfile 4) Tidied up G8JCFSDR Trace mode shortcut 5) Added a shortcut to instructions of how to control the G8JCFSDR from the keyboard - I use these to tune the SDR with a Griffin Powermate 6) Added a shortcut to make it very easy to send G8JCF and email using the http://g8jcf.uk website The G8JCFSDR when currently run in Trace mode, stores the Logfile in 'c:\temp', which is somewhat untidy. Build 280, now uses the user specific environment variable %TEMP% for the directory of where to store the Logfile. Other changes:- 1) I discovered that Hamlib support has been broken for a long time because of a missing .DLL file, which I have now rectified - does anybody use Hamlib ? 2) The addition of two new receiver interfaces, both of which are unusable by anyone else except myself. If you have a DRT1 and want to use it under Windows with a USB interface, then contact me becauise I do have code for an Arduino Uno which carries out the USB to bit-banging the lines into a DRT1, ie the interface from the PC to the Arduino is a very simple line oriented ASCII protocol, eg f 198000<RETURN>, and the Uno does the work of calculating the DDS register values and then sending them into the DDS chip. In the "good 'ol days" with real serial ports on PCs, this work was all done inside the PC and then bit banged out on the TX, DTR, & DTE lines, but that doesn't work with most USB<->Serial adapters (just too slow). *Finally, Yahoo is shutting down its Yahoo GROUPS service on December 14th 2019, with no more user content allowed to be uploaded after Monday, October 21st, so we will have to migrate to another group site. I have setup a G8JCFSDR group over at GROUPS.IO. Unfortunately to automatically migrate all users and content from Yahoo Groups to Groups.io would cost me USD 220, so [email protected] will start off very sparse, but I would encourage all existing users of G8JCFSDR at Yahoo Groups to sign up for [email protected] please.* 73s Peter - GM8JCF

Hi all, I'm developping a new firmware to control the Elektor SDR Shield 2.0. The goal of this development is to have a unique firmware for a general usage of the shield but also compatible with G8GCFSDR build 280. Currently additional commands can set various frequencies from 3049Hz to 112.5MHz onto CLK0, CLK1 or CLK2 outputs. A REST api is also in development. An additional Windows EXE is also in development. The goal of this program is to converse with the new firmware from a batch command line or as a web CGI program. Best regards. jmP

Hi I have generated a beta release of the G8JCFSDR V1.0 Build 281, which may be downloaded from http://www.g8jcf.uk/g8jcfsdr_drt1/downloads/setup_G8JCFSDR_281.exe *Release Notes for Elektor SDR Shield aka SDR Reloaded V1.0 Build 281* G8JCFSDR V 1.0 Build 281 fully supports the Elektor SDR Shield. *Frequency Calibration V1.0 Build 281 * The crystal on the Si5351 is uncalibrated, so you will need to calibrate the software to allow for the crystal. Go into Config, and click the Calibrate button on the General tab which will bring up the calibrate window. Click the Help button to view the procedure you will need to follow. G8JCFSDR Build 281 incorporates an improved SDR Shield frequency calibration algorithm. A new version of the Arduino firmware, V 1.3, is included with build 281 and should be installed when prompted. I am very grateful for the perseverance of Jean-Marc Paratte for figuring out that the original frequency calibration only worked 100% accurately at 10MHz. *IQ and SMeter Calibration* G8JCFSDR Build 281 uses CLK0 of the SI5351 to generate :- a) IQ Calibration signal - the IQ calibration signal is generated at +1KHz from the currently tuned frequency, and if you set the G8JCFSDR to USB mode you will hear a 1 Khz tone when you switch on the IQ calibration signal. b) SMeter 10KHz signal - see Burkhard Kainka's SDR Hands On book, Chapter 7, section 7.2 pages 79-80 (English Translation) for details of how the 10KHz signal is used. These functions are accessed using the Calibrate button on the General Tab in Config. *Hamlib Support V1.0 Build 281* Build 281 of the G8JCFSDR has a completely different mechanism for using the Hamlib interface to rigs. This new method has been tested with an ICOM IC-7200, and supports the following methods with the GM8JCFSDR 1) Set Frequency 2) Set Mode, eg USB, LSB, AM, FM etc 3) Set Bandwidth When in Hamlib mode, the Notch filtering, Noise Reduction & Noise Blanking mechanisms of the G8JCFSDR will still function. Build 281 support for Hamlib is still in very early form and will be improved upon over time. *Firmware Upload* The first time you run the G8JCFSDR and select the Elektor SDR Shield you will be prompted by the G8JCFSDR to upload the new firmware to the Arduino Nano. If you are having problems uploading the firmware, use the StartMenu entry "XLoader" to manually upload the firmware named "si5351vfoGM8JCF.hex" usually located in "C:\Program Files (x86)\G8JCFSDR\ArduinoCode". The StartMenu entry should place you in the correct directory. Usually I would just place the setup file on the G8JCFSDR website, adjust the URLs and make Build 281 generally available, but the G8JCFSDR Build 281 includes many changes and extensions which I would like tested before making it widely available hence why it's classed as a Beta made available from a direct URL. Feedback will be very graefully received. 73s Peter - GM8JCF

My arduino uno clone uses CH340 ftdi chip. Does this cause problems with your app? It works fine with Arduino IDE. Which serial option should I use for USB connection to arduino? I get error L70 = 70438 object not supported ..... Demands that I update arduino app for sdrshield. Have done so, but have to use xloader. appears to stay running after cancelling these messages, but no sign on screen that a signal is being seen. Help! / thanks
