Using modes without SDR support.

Audio files for testing software.

Here, a page listing software for the RTL dongle but much of this may also be used with other SDRs. All platforms. Also a list of decoding programs that may be used with SDRs.

Which way to connect I & Q? PSDR is the only software that does not have an IQ switch. Wire your Softrock so this is correct then switch IQ in other softwares if necessary.

CW? Quite a bit here, connecting keys/keyers to Rocky/PSDR and settings. http://groups.yahoo.com/group/softrock40/message/39746 Here, a 30-day trial of an IQ mode CW decoder with  transmit http://www.polar-electric.com/Morse/MRP40-EN/MRP40-SDR.html


(A) 

ROCKY EASY TO GET GOING BUT IT SEEMS IT IS NOT WORKING WITH SOME HARDWARE... MOST INSTRUCTIONS ARE ON THE ROCKY SITE, LOOK!! For CW and PSK transmit and SSB receive maybe you will not beat Rocky. http://www.dxatlas.com/Rocky This works with the USB controller.
Tony explains how to setup Rocky for 40 fixed  frequencies. http://groups.yahoo.com/group/softrock40/message/21692 A good description of Rocky's ini http://www.wb5rvz.com/sdr/RX_V8_3/Sw1Settings.htm  

February 2011:- Rocky http://www.dxatlas.com/Rocky/ Version 3.7 is now here. It is intended to work with internal and on-board soundcards in Vista and Windows 7 but some are finding problems with on-board sound..   It will work with USB sound and some PCI cards.  One way has been suggested that overcomes this flaw. Use VAC to connect Rocky to a card it does not see as in Using modes without SDR support below.

 Rocky has trouble - it does not see internal soundcards... VAC will do the job. You need to set up another "cable" for output. Another way to get around the Rocky issue is to use a USB sound card. Rocky can find those. Winrad and HDSDR work fine on Vista.  Tom KM5H This old post will be true for Windows 7.


A MESSAGE FROM TONY TO HELP BEGINNERS WITH ROCKY.

Alex has lots of good information on using Rocky on his website:
Rocky Software http://www.dxatlas.com/rocky/ >
There is a link posted within Alex's information for using a USB connection with the Si570 and getting the USB driver.
I think if you go carefully through the information Alex has posted on his website you will be able to get the RXTX board playing properly."

On this page there are a few notes on setting up Rocky http://sites.google.com/site/g4zfqradio/setuprocky  and editing the ini file.

Problems with Rocky?  Uninstalling Rocky does work as expected, the ini file is left in "Program Files" Deleting this restores correct operation upon a fresh installation. (Just deleting (or renaming) the Rocky.ini file might rectify the problem)  In Windows 7 Rocky's ini file is located at " C:\Users\'Name'\AppData\Roaming\Afreet\Products\Rocky\ "



(B) 

FAROS / CW Skimmer (Shareware http://www.dxatlas.com ) See http://www.ayoko.net/faros/  A CAT controlled Softrock, look at this, http://groups.yahoo.com/group/softrock40/message/30895  and some around the same date. "My code recognizes a subset of Yaesu FT-817 CAT command set (because I have one). I also needed N8VB vCOM Virtual Serial Ports Driver to route back Faros commands to my program. To be specific, Faros opens COM6 and my program opens COM16 and chat over the Virtual Serial Ports Driver. On the other hand, I did not need to change firmware in ATtiny micro controller. One COM port, several uses? http://www.eterlogic.com/Products.VSPE.html  


(C) From Flex Radio http://www.flex-radio.com/products.aspx?topic=powersdr1x This has been modified to suit Softrocks, versions below.

POWER SDR SEVERAL VERSIONS! MORE SETUP OPTIONS, THEREFORE IT IS BETTER TO TRY THIS ONCE THE SOFTROCK IS WORKING. Most up to date PDSDR-IQ in section C2 below

This software is modified from http://www.flex-radio.com/ there is much information on this site. http://www.flex-radio.com/Products.aspx?topic=powersdr1x Look at the drop-down menus. They have allowed amateurs to alter this software, several people have added Softrock compatibility. 

GENERAL INFORMATION FOR ALL VERSIONS I am trying to keep the versions separate BUT there are more things common to all versions than there are differences between the individual versions. 

  Useful links for PSDR setup http://www.wb5rvz.com/sdr/ensemble/psdriq.htm  http://groups.yahoo.com/group/powersdr-iq/links  Most questions will be fully answered here. The SDR-1000_Operating_Manual_v1.8.0 covers everything. Front.pdf, the index, Chapters 6/7 is where the PSDR setup starts.

Look at the PDF files here http://powersdr-sr40.sourceforge.net/  Although they will not cover everything the two manuals at "Download" give a good idea of how to setup PSDR. There is lots of information at Flex's site. http://www.flex-radio.com/ look at the "Support" Tab. Some settings can degrade performance. Do not make adjustments unless you know what they do!

Bob's summary of various versions, use with Softrock http://groups.yahoo.com/group/softrock40/message/47069 

Doug's notes Re: Need idiots guide to setting up Power SDR http://groups.yahoo.com/group/softrock40/message/39028  Bob's follow-up http://groups.yahoo.com/group/softrock40/message/39034          Also http://www.genesisradio.com.au/help/help1.html 

Also is a version with USB to I2C support. This is now available, on http://www.sdr-kits.net/USB/USB_Description.html   is where you find all the information required.
Flexradio download site for latest version of PowerSDR  http://support.flex-radio.com/Downloads.aspx?fr=1  

Ham Radio Deluxe and PSDR. http://www.ham-radio-deluxe.com/ I believe the two work together with CAT, this will allow DM780 digital modes to be used. Forum http://forums.ham-radio.ch/

CW Key in PSDR http://groups.yahoo.com/group/softrock40/message/51234  

If PSDR will not start reinstallation does not work! "You have to find and delete the database.xml settings file which it does not reside in the installation folder. The database.xml file resides for XP in C:\Documents and Settings\<user name>\Application Data\FlexRadio Systems\PowerSDR v1.19.3 and for Vista in C:\Users\<user name>\AppData\Roaming\FlexRadio Systems\PowerSDR v1.19.3" Christos  Earlier versions of PSDR put the database file in the Program folder, Genesis database.xml, others use a different format PowerSDR.mdb.
 It is possible to save and select these files to use different configurations, or restore operation if it gets corrupted.


(C1) 

PowerSDR-SR40 - PE1NNZ An older version but may well suit non-supported soundcards better than the newer versions. http://powersdr-sr40.sourceforge.net/  Good help files here. couples a Softrock with a Si570 to enable control via USB or even a parallel port. (LPT) "With kits utilizing the Si570, and properly configured to use same, the software itself continuously changes the center frequency as you tune across a band for which you have selected the proper BPF, etc"  Cesco explained to me that this technique makes image rejection easier. If the soundcard is used at one frequency the relatively small amount of phase shift at RF over a band my be ignored. Just one setting per band is needed. This is best used with frequency-agile Softrocks but a crystal controlled one may be used.

For v1.9.0, in "set up" the 'Radio' option can be set to 'SoftRock40' or it is better setting it to 'SDR1000'. With the USB interface that latter gives continuous tuning rather than jumping when you reach the extremes of the displayed tuning range.  Bob G8VOI.


(C2) 

 PSDR-IQ Christos SV1EIA's versionMay only be used with frequency agile Softrocks. NOT crystal controlled. Also has parallel port control option but different connections to Guido's (SEE Section C1 above)! The parallel port may also be used for controlling BPFs CW key and PTT. 

2013 A new approach from Christos

PSDR for Homemade Rigs. Go to http://code.google.com/p/powersdr-iq/downloads/list for the files. Instructions included, follow carefully.

This uses the Flex version of PSDR and just changes a few files. First reports are favorable, In time it will be enhanced. Should work on all Windows.

May 2014 Look at Robby, WB5RBZ's PowerSDR-IQ setup page  http://www.wb5rvz.org/common/PowerSDR_244_Installation 


Many useful links here. http://groups.yahoo.com/group/powersdr-iq/links/?prop=eupdate  BUT LOOK ABOVE October 2012.

Project home FOR ALL VERSIONS BY CHRISTOS  http://code.google.com/p/powersdr-iq/ There is also a dedicated group http://groups.yahoo.com/group/powersdr-iq/   SKINS for v2 (1.19***) http://groups.yahoo.com/group/powersdr-iq/files/  PSDR2_CPG_***.exe If you do not have NET then Microsoft Update is the best place to go. Maybe 

   http://www.microsoft.com/downloads/details.aspx?FamilyID=AB99342F-5D1A-413D-8319-81DA479AB0D7&displaylang=en  NET download   


January 2010 For Vista and Windows 7, as well as XP, Christos has modified PSDR v2 with the addition of Si570 USB control. http://code.google.com/p/powersdr-iq/downloads/list  Image Rejection:- Is enabled internally. Flex has automated this whole process and is naming it WBIR (Wide Band Image Rejection) Note on unsupported cards VOX does not work and TX mute can be a problem.   

Older version, fine for XP, more facilities than v2 above. PowerSDR-IQ v1.12.20 http://code.google.com/p/powersdr-iq/downloads/list   Has embedded support for the loop.dll method of virtual audio cable, an alternative for some applications to VAC. These applications can be Easypal FDMDV WinDRM MMTTY MMVARI MSSTV MultiPSK Many thanks to Cesco HB9TLK for his work and his assistance on this integration.73,Christos SV1EIA".......  This version now has automatic image rejection for receive. I've modified the receive passband and you can have really extended receive, you can even try to decode the broadband NOAA satellites by adjusting the filter dials in the lower right corner or drag the rx passband edges with the mouse, iirc up to 40KHz wide. 73, Christos SV1EIA 

For PSDR-IQ v1.12.20, you need to select 'SDR(Si570)' as the radio type.

."By design PSDR-IQ mutes the Windows default sound device when switched to transmit. This is different to the behavior of PSDR1.9-sr40, My Soundblaster card, which I use for Tx/Rx IQ, was installed as the default sound device so the Tx IQ was being muted when transmit was selected - hence no rf output. Changing the default sound device (in Control Panel) to be the on-board audio hardware has solved the problem. 73, Geoff G3WPD"
This PSDR also has the fixed audio frequency feature to make image rejection easier.


...(C2) POWER SDR-IQ continued...

PSDR setup http://groups.yahoo.com/group/powersdr-iq/message/1626  Basic settings for PDSR-IQ with the USB Softrock. http://www.wb5rvz.com/sdr/ensemble/psdriq.htm  PSDR-IQ TX IQ rejection http://kc.flexradio.com/KnowledgebaseArticle50157.aspx?Keywords=transmit+image+rejection+adjust  

PSDR-IQ is targeted to the frequency agile homebrew rigs like Softrocks with Si570, UHFSDR, PMSDR, 995X, etc. Christos shifts the frequency in TX mode to give the lowest possible spurious signals. He says:-   "For 6.2 softrocks there is either the Si570XTall or the USBSynth that could be used. In my own 6.2 (I have three of them) I've added the Si570 board from Dave's WB6DHW Si570 little board and control it either via LPT or via his HSUSB board.
If you insist on using a crystal on your 6.2 you have to use some other PSDR flavor since I do not support TX under this configuration due to FCC/ITU regulations, you can read past posts on the subject and they could be enlightening." 

CW with PDSR IQ http://groups.yahoo.com/group/powersdr-iq/message/766  PSDR, CW and LPT connection. http://groups.yahoo.com/group/softrock40/message/46261  

Since you have the M-AudioD44 in supported, you do not need a second card. Here is a link that describes hot to set it up with the SDR1K but I guess you will get the idea for your RxTx software too.  http://support.flex-radio.com/Downloads.aspx?id=7 The photo figure-1 in page 2 is actually the key to proper connections.

When you put together a 6.3RxTx [or any Softrock] and want to Tx,  "Give special attention to the "LPT_Address_(-blank-)"       Christos 

At the top of Robby's setup page is USBtoSDR information also here http://code.google.com/p/usb2sdr/  We wait for the next issue of these specialised "soundcard" and Softrock controllers.

November 2011 USB2SDR Initial Setup Guide http://groups.yahoo.com/group/powersdr-iq/files/USB2SDR%20Guide/StartupGuide.pdf

The USB2SDR is a dedicated "soundcard" and controller which may be interfaced with a Softrock or similar SDR. As it is built for SDR 192Ksps works well. See Robby's pages http://www.wb5rvz.com/usb2sdr/index.htm While this will only work with a special version of PowerSDR it will give low latency SSB and CW. Probably the ultimate for Softrock-type front ends.


(C3) 

The version of PSDR at http://sdr-kits.net links to the SR-40 version works with the USB AVR chip to give smooth tuning of the Si570 over a range of frequencies, (+/- 3500ppm.) This smooth tuning is also implemented in Fred's modified AVR code. 


(C4)

PSDR IF Panadaptor

 http://www.wu2x.com/sdr.html A version of the PowerSDR software designed for those using the Softrock as an IF panadaptor in a radio with CAT. Use it with HRD. (Ham Radio Deluxe)       Using it with Softrock http://www.zs6buj.com/files/PowerSDR-sr40_Setup.pdf   This continues to be developed  http://code.google.com/p/powersdr-if-stage/   Talks to Kenwoods directly, also with Ham Radio Deluxe to show the actual frequency. 

March 2011 PSDR-IF group http://groups.google.com/group/powersdr-if-stage/browse_thread/thread/392f6b4844cfd235?hl=en 

Ham Radio Deluxe may be used with PSDR, I think it may be used directly but here is another way http://lists.vhfwiki.com/cgi-bin/mailman/listinfo/minideluxe


NaP3 other variation of PSDR exclusively for panadapters. http://www.telepostinc.com/NaP3.html CAT with selected rigs, also non CAT for older rigs.


(C5)

PSDR GENESIS A version intended for the Genesis range of equipment but will have some use with other SDRs.

March 2013 Use with Softrocks. http://groups.yahoo.com/group/softrock40/message/72868 Will work with early crystal controlled Softrock RXTXs as well as Si570 versions. 

http://www.genesisradio.com.au/GSDR/  A new version of Genesis PowerSDR(TM) V1.1 is now available for download. Features include - large PANAFALLT display mode- 99 store/recall memories- independent TX and RX I/Q channel swap- main screen optimized for two monitor configuration- detailed 32x display zoom- unique RX and TX image calibration. This exe is the program, it does not install itself. PROGRAM UPDATES:- The newest is always here: http://www.genesisradio.com.au/GSDR/new/  Look for the .zip files. one says install.zip those are "base files". unpack it into an empty folder..... Then look for the "update" file that has the newest date. unpack it into the same folder as the install files. Click 'yes" to overwrite files.

Feb 2010 Robby:- "I have put together some builders notes on a couple of the Genesis Radio kits http://www.wb5rvz.com/sdr/genesis_g40/g40/ http://www.wb5rvz.com/sdr/g3020/ "  Installation notes, need to be a member.. http://groups.yahoo.com/group/GenesisRadio/message/2152  

March 2011 The GSDR Manual: ( English translation of YT7PWR manual) which can be downloaded from http://www.genesisradio.com.au/GSDR/English_GSDR.doc shows a lot of default PSDR settings, as well as Genesis specifics. You will probably have to join the group.

SDR# (SDRSharp)  

 http://sdrsharp.com/ 
This is an easy setup software for RX only.  Works with Funcube and RTL Dongles and Si570 Softrock.

July 2012 now fits a small netbook screen.  
August 2012 RTL Dongle see http://rtlsdr.org/softwarewindows for instructions. 

See http://sites.google.com/site/g4zfqradio/connecting-soundcard-sdr-to-computer  this page has my installation and operation instructions.



 

(E)

WINRAD and developments. 

Fred's USB DLL  All information on the bottom of this page. http://pe0fko.nl/ExtIO_Si570/   Put the ExtIO_Si570.dll file into the Winrad/HDSDR folder , press H when it is running.  


Original Winrad

http://www.winrad.org/ The first, a good RX only program. Alberto stopped his development released the source for others. This works in Full-Screen mode, do not forget that on the keyboard Alt - Tab moves from window to window. Keep another window on top of Winrad http://www.abstractpath.com/powermenu/    

http://groups.yahoo.com/group/soft_radio/files/ik4thl/  Synchronise WinRad with Ham Radio Deluxe HRD

This site for use with RTL/E4000 stick. http://wiki.spench.net/wiki/USRP_Interfaces all Winrad derivatives.



 HDSDR

The best Winrad development. Was called Winrad HD. April 2012 TX capability. http://www.hdsdr.de/   and PE0FKO's latest dll.

Setup and operation instructions. https://sites.google.com/site/g4zfqradio/installing-and-using-hdsdr  

Note it is possible to use LPT control with versions of Winrad.  PE1NNZ's dll and msvcr71d.dll need to be put in the folder. The dll needs to be selected and/or activated when starting Winrad.  Note no frequency calibration is provided. BUT June 2011, HDSDR does, LPT control with frequency correction. And a version for serial control.... http://212.254.198.33/extio_si570_serial.zip  


WinradF April 2011 Currently unavailable.


WinradPlus July 2012 I think that no version of this will work, the time limit has expired. Building on Alberto's code Sandro is going commercial.  January 2012 There is another version released. Be aware this is  time limited. This is intended eventually to be commercial software.  http://www.wrplus.altervista.org/ January 2011:- This version includes a wide FM detector for broadcast stations. September 2010 another version, with notches and other improvements see http://groups.yahoo.com/group/softrock40/message/48109     For the separate, fixed, window option make text file in the wrplus Program Folder. Inside just put "wrplus.exe -wv" (without the " ") rename this file WinradPlus.bat ( NOT .txt )and make a shortcut to it.



(F)  


December 24 2012 the Preview of version 2 http://v2.sdr-radio.com/Previews.aspx 
This will replace version 1.

Version 1 http://www.sdr-radio.com/Home/tabid/384/language/en-US/Default.aspx This was commercial software being developed for RFspace, and for other manufacturers. But it  is free to be used by amateurs. No longer under development, replaced by Version 2.

Like all Simon's work this has a very polished look.  This is a stand-alone console, satellite reception and (eventually) data modes. It uses Omni-Rig to use with, or alongside, another rig . There are many "bells and whistles" 





(G) 

Pebble SDR A simple SDR program with station database. http://sites.google.com/site/pebblesdr Written for Windows 7 but works on XP, maybe others. (Future versions for Linux, Mac?)

 Version 221 Feb 2011 for the FCD.



(H) DRM Dream There are IQ versions but Sodira incorporates this  See section (Q) belowhttp://www.dsp4swls.de/sodira/sodiraeng.html possibly all you need.


Other links:- Try http://www.df9cy.de/download.htm or maybe http://www.elexs.de/drm.htm (This is not an installation, the package needs to be extracted to a suitable folder and shortcuts made.) Maybe... http://xoomer.virgilio.it/i5xww/drm.htm and www.b-kainka.de/ 

You may find something here..[ .http://www.sat-schneider.de/DRM/DRM.htm mainly commercial] [ http://pessoal.onda.com.br/rjamorim/dream.zip  2006 version of Dream.] [http://home.arcor.de/carsten.knuetter/drm.htm #Disco Will tune receivers, it does not seem to include the Softrock but maybe there is something I do not know... ] http://www.dsp4swls.de/sodira/sodiraeng.html  Sodira Has DRM demodulation, Essentially for commercial RXs. Does not seem to have image rejection so may work with VAC. Does work with a Softrock, tune 12K Hz lower. http://knallfunke.de/drm/empfaenger/SDRelektor/ 

October 2010 Steve, M0ZEH has a page here http://m0zeh-sdr.blogspot.com/2010/03/dream-drm-receiver-commercial-stations.html  

[Source files http://sourceforge.net/apps/mediawiki/drm/index.php?title=Main_Page ] This may be used with a Softrock to receive short wave DRM broadcasts (and analogue modes!). (installation file, default to C:\ and no shortcut is made.) THIS PROGRAM REQUIRES A SPECIAL SHORTCUT TO START IN STAND-ALONE I/Q MODE. It appears to work when started normally but is in the mode for PSDR. 

When you install Dream take note of where it installs, C:\Dream by default, you may wish to direct it to "C:\Program Files\Dream\"  Opening the folder and double clicking "Dream.exe" starts it in normal mode, NOT I/Q mode. In the program folder where it is installed you will find "receive_iq.bat". If you changed the folder from the default you will have to edit the path in this file. Then dragging the file to the Start Menu will give a shortcut to it. IQ mode is stand-alone, it acts as it's own SDR but the frequency has to be changed by moving the SDR Centre frequency. Using Dream in IQ mode it seems that the centre frequency is the stated transmission frequency, that's what it works on, I find it works with a centre frequency from about -1KHz to +12KHz of the nominal.
Using PSDR at 48KHz sample rate, I RX Voice of Russia, quoted as 7325MHz in the listing, with a centre frequency from 7.304 to 7.337. This includes reception on the centre frequency. So that equates to nominal frequency -21/+12KHz. This checks with BR-BR5akt on quoted 6.085MHz. In both modes you may have to toggle the "flip spectrum" box in the Evaluation Dialog to be able to decode a signal. Note my references to centre frequency are relevant to those using fixed tuning or independent controllers. SDR programs with Si570s should be setup to compensate.

Dream may be used in normal mode with PSDR and other software using VAC.  . For the baseband audio to be correct the SDR filter must be 10KHz wide.

Using DRM with PDSR there is no confusion with frequencies. DRM's Input Spectrum/Waterfall shows the signal from 7-17KHz. However, with no signal the displays do not look very different. PSDR offsets the LO by 12KHz for DRM. To get this same offset on the Input Spectrum/Waterfall with I/Q mode requires a LO offset of +6KHz, I do not know if this is relevant. In I/Q mode I find it difficult to determine the "correct" offset, it just scans and locks.
Some PSDR setup with DRM http://powersdr-iq.googlecode.com/files/DRM_PowerSDR-IQ.pdf http://powersdr-iq.googlecode.com/files/DRM_Settings.pdf http://www.iw2nzx.it/?p=253  73, Christos SV1EIA

 When the program is running View - Station Dialog.. opens a list of DRM stations. Update this and select a suitable frequency.  The SNR and waterfall etc may be observed by View - Evaluation Dialog..  http://www.wwdxc.de/drm.htm   can be good site for schedules and TX / reception info.

Spectrum Laboratory. http://www.qsl.net/dl4yhf/spectra1.html  

Windows 7. This program writes to it's program folder so do not install it in "Program Files".


SpecLab an audio analysis program. Records and analyses audio. This has many components including an LF soundcard receiver and I/Q input making a SDR receiver. Can be run at low sample rates so that a relatively slow computer can be used.  I use four Softrocks at the same time with this software, using a sample rate of 8KHz, for fixed frequency radio monitoring. 

"Of course the combination SpecLab/Softrock is not display only. It can be used as demodulator with filtered / converted / inverted audio output, i.e. you can use it as USB / LSB / CW receiver. With some more fiddling, you can also use it as an FM / AM demodulator (the "dsp blackboxes" must be used to demodulate the latter).
As a starting point, use the configuration "Quick Settings - Image Canceling DC receivers (I/Q) - Then select one of the soundcard options."  [But note this will work using as low as 8KHz sampling but with a narrow bandwidth.]. When you open the Spectrum Lab Components window after this, you'll see both inputs from the (stereo) soundcard go to the digital filter in the middle of the window. The filter actually does the I/Q processing, filtering, and conversion of the complex signal into a real signal which is finally sent to the output. ............You will see three diamonds on the main frequency scale, which control the input center frequency ("VFO"), the audio bandwidth, and the audio center frequency (traditionally called "CW pitch").In this configuration, the downconverted and filtered signal is combined into a real output, because *listening* to an I/Q signal (inphase component on the left ear, quadrature component on the right ear) doesn't make much sense - though it may sound interesting. This can be configured on the filter control panel (set the option "I/Q output" for the filter) 73, Wolf DL4YHF .  "
A useful post about using the Softrock at LF, you need to join the group. http://groups.yahoo.com/group/SpectrumLab/message/1505  

This software, unlike the normal SDR program, can be setup to display and record frequencies and amplitudes to a high degree of precision, (and accuracy if calibrated.)

WSPR IQ February 2012 still a beta version of WSPR that works with Softrocks and other SDR is at http://wsprnet.org Some things may not work properly.  I think it's receiving capability is not quite so good compared with the PDSR/VAC method but give it a try. It is easy to setup if you read the updated instructions. Look for version 2.1r2263 or later. Note that all IQ versions require setting up each time you use it. RX (AND likely TX)  image suppression is not saved maybe not the TX Audio setting. You may note the TX settings but RX image needs to be reset.

Windows 7:- Location of WSPR's ini file. C:\Users\.....\AppData\Local\VirtualStore\Program Files (x86)\WSPR 

Setting Fiq in WSPR 2.11 IQ mode for fixed frequency (=LO = crystal controlled centre frequency) Softrocks.
The default Fiq of 12000Hz is for a Local Oscillator that is 12000Hz below Dial Frequency.
Fiq = WSPR Dial Frequency - Local Oscillator frequency [LO]. [If LO is higher than Dial then Fiq is negative]
TX image frequency = Dial Frequency - 2(Fiq) [If LO is high this frequency will be higher than the Dial frequency.]
I have tested this for values of Fiq up to +/- 20000 and it works correctly with the image correctly suppressed.
If Reverse Rx IQ is incorrect it may still appear to work BUT it will be looking at the image and very poor results will be obtained. [If you put the LO the other side, but Fiq -3000, you will see the WSPR signals stronger but inverted so they are not decoded.] Unless you have a special reason do not change Dial Frequency or RX BFO.

Linrad http://www.sm5bsz.com/linuxdsp/linrad.htm  Lots of links to get the beginner going as well as the more experienced. Windows users:- This may be used in Windows but most will find it tricky to learn and setup, the interface can be considered as basic. Give yourself lots of time, read a lot, use the F1 key. Regular users say the display has unique features. Has Si570 support.

For receive-only you could do worse than try lysdr: https://github.com/gordonjcp/lysdr  It's much easier to get going than anything else. Gordon MM0YEQ

Linux SDR, Quisk: http://james.ahlstrom.name/quisk/  http://groups.yahoo.com/group/softrock40/message/32870  May make sense to somebody!

Basic DSP - which is a lot of fun to play with - create your own software defined receiver! For Linux and Windows. http://tech.groups.yahoo.com/group/basicdsp/ 

Using Wine: MOKGK http://www.m0kgk.co.uk/sdr/download.php  MOKGK 1.0 receive works under wine without trouble.

Hello all just wanted to let everyone I have gotten some positive results with ubuntu linux, dttsp, fldigi.I am able to receive and everything seems to be working well. I'm moving forward on getting the transmitting to work I am also documenting my 5 watt amp project. I have started to document the steps for this setup on my blog. Hope this helps anyone wishing to break away from windows. http://valdez.bz/wordpress   Good luck, dan nm5dv.

Linux For the Si570 control, try VK6JBL's usbsoftrock. It is stable, simple, feature rich and easy to use. http://groups.yahoo.com/group/softrock40/files/VK6JBL/



(M) KGKSDR http://www.m0kgk.co.uk/sdr/index.php  CW, SSB transmit with receive only for AM and FM Also IQOUT, provides a configurable IQ output from a soundcard suitable for testing SDR transmitters.  His Yahoo group. http://groups.yahoo.com/group/kgksdr/ 

"I just loaded a program called M0KGK Receiver which along with a driver called ASOFORALL worked well on my Vista machine. It also has the transmit functions."




(N) MAC   Just some links, I do not use a MAC.

May 2014 HDSDR on a MAC https://groups.yahoo.com/neo/groups/softrock40/conversations/messages/77922

Mac Dec 2011 http://groups.yahoo.com/group/softrock40/message/59913  

 I've uploaded [This will be in Yahoo Sofrock40 files area] under my callsign (VK6JBL) a program I wrote for myself, but for which I gather there is interest from other people as well. This is primarily intended to allow Sebastian Mrozek's DSP Radio to control a RXTX 6.3 fitted with Tony's USB-I2C board. It will also function standalone and should in theory control a kit from sdr-kits similar to the USB_Synth program, however this is untested.
Limited testing, full of bugs etc etc. It's also limited to Mac OS 10.5 and intel processors at present. There's a lot of work still to be done, but maybe someone finds it useful now.

Someone said "have a look at JavaSDR. Link dead[https://java-sdr.dev.java.net/]  I find it to be pleasant software. I use it on OS X but it runs on Linux as well.

I have been looking for this for a while, so I am please to share it. If you are looking for an equivalent to VAC (Virtual Audio Cable) for Max OS X, ..(dead link).. less universal. http://code.google.com/p/soundflower/  So you can now link DSP Radio or GNU Radio, with Multimode, fldigi... I have not compared to solutions yet. Just informing. 73,Yan.---Yannick DEVOS - XV4TUJ

The "sound card" we are designing works great under OSX, see: Link dead, and maybe this is now finished. [ http://groups.google.com/group/sdr-widget/web/SDR-Widget-Lite_OSX.pngn]  73 Alex

Using USB Softrocks with a MAC OSX:- http://groups.yahoo.com/group/softrock40/message/50145  SUCCESS!!! Robin's suggestion about editing the VmWare .vmx file to add the line usb.quirks.device0= "0x16c0:0x05dc skip-reset" allowed Windows to recognize the device and allowed me to install the drivers.

(O) 

Multi PSK  http://f6cte.free.fr/index_anglais.htm A multimode program that can use the I/Q signals from an SDR. There is manual I/Q adjustment.

It is possible to use macros in MultiPSK   to control the Softrock http://groups.yahoo.com/group/softrock40/message/47811  A web search will find the files to avoid the need to register into yet another group.

The unregistered version will read and encode very many modes, payment enables lots of extras. Spend some time with this, the interface is a little different but here is a single program that works with SDR TX/RX. 

January 2011 "I have been using MultiPSK for the past year. Some people are put off by the UI but it is a full-featured digital mode program with a limited but functional SDR front end built-in. It is easy to setup and requires no additional software. It has full support for the softrock through the USB port - both PTT and frequency control. It also has built-in support for the DXLab suite. Ed WB6YTE"


(P) 

For those interested in using their iPhone, iPod touch, or iPad for SDR "There is now a free app available on the iTunes App Store: http://itunes.apple.com/us/app/isdr/id375603584?mt=8 Or you can read more about it here: http://isdr.digitalconfections.com 73, Charles NZ0I"


(Q) 

Sodira http://www.dsp4swls.de/sodira/sodiraeng.html A RX program January 2012 Easy DRM, auto image rejection, Si570 with ExtIO. All modes, a good program. 

A few notes here https://sites.google.com/site/g4zfqradio/sdronasus


(R)

IQRec From Fred, PE0FKO This will record the output from a SDR. The wav file can then be used with another SDR program. http://home.ict.nl/~fredkrom/pe0fko/IQRec/ 


(S) 

G3PLX

TX only program http://www.g4jnt.com/SDRTxSW.htm  This is fairly simple but will TX SSB, FM and AM. It uses a low soundcard sample rate so will need to be used close to, or on, the centre frequency. This looks interesting for use with one of the RX only programs. Strictly for experimenters!


(T)

 

 SDR-J JSDR http://www.sdr-j.tk/index.html Linux and a 32 bit and 64 bit version tested on XP and W7. Various SDRs supported, soundcard or IQ input including RTL dongles. Various data decoders built in.
Just unzip into a Program Folder and run the executables. Look in the program folder for help files but these may be outdated.
SW receiver:- Soundcard support for the Elector SDR. I think this can be used as a fixed tuned program. Has various data decoders.
FM receiver:- May be used with the RTL Dongle. Stereo and RDS.
Viewer:- Only a spectrum viewer.
There is also a 64 bit version for DRM reception.


(U) 

G8JCFSDR

 RX with no Si570 support.Last version was 2009  http://www.g8jcf.dyndns.org/ www.alltomelektronik.se/ Files/070565-QuickStartGuide.pdf 


(V) 

AMSR by PE0FKO  http://pe0fko.nl/AMSR/ This may be regarded as a curiosity. It is Fred's all mode SDR receive system. You may use CFGSR to set a centre frequency. This can be entered in "Options" Note HERTZ! It is interesting but basic, no extra image rejection, just a simple experimental RX.

 

(W) 

Spectravue

  http://www.moetronix.com/spectravue.htm 

This has a soundcard input option. It may be used with a Softrock but has no tuning capability. The centre frequency may be set in "Soundcard setup". This might best be used with a fixed frequency Lite but CFGSR could be used to tune a Si570.

It has an external radio feature. 


(X) GNU There are Windows binaries here, but it seems to be aimed at Linux users.

 http://code.ettus.com/redmine/ettus/projects/uhd/wiki/GNURadio_Windows 

 http://files.ettus.com/binaries/gnuradio/latest_stable/

Note Python must first be installed. From the page below it seems there is a lot of preparatory work to be done.

http://gnuradio.org/redmine/projects/gnuradio/wiki/WindowsInstall 



(Y) 

Quisk http://james.ahlstrom.name/quisk/ RX/TX CW operators might try this, QSK. Also SSB. Simple, if you do not mind editing configuration files. There is a warning about this but Linux programs on Windows never seem simple for Windows users.

Like GNU, above, Python must first be installed. My first setup https://sites.google.com/site/g4zfqradio/quisk_for_windows



2 Modes not yet supported by these SDR programs.  

There are various pages like this one, helping to identify them http://wiki.ham-radio-deluxe.com/index.php?title=DigitalSignals  Hear and see digital modes. This is a Ham Radio deluxe ( http://www.ham-radio-deluxe.com/ ) Wiki. PSDR is one of HRD's supported radios. DM780 is HRD's digital mode module. Also http://www.w1hkj.com/FldigiHelp-3.12/Modes/index.htm

This is getting a bit more complicated, but many modes could be run together with an SDR program. The problem is going to be getting audio from one to another. One way is to use a separate soundcard for the other program and link them together by audio cables. I have found that three USB audio "cards" will operate together. Just plug them in, sorting out which is which with the software can be a matter of trial and error. It seems very few use this method, it is potentially inferior to VAC but do not be afraid to try more than one soundcard!

Virtual Audio Cable (VAC)  http://software.muzychenko.net/eng/vac.html Or an alternative http://vb-audio.pagesperso-orange.fr/Cable/index.htm (one cable free, maximum 3 cables with donation.) these link programs by software.  As time goes by maybe programs will have this linking built in. Some soundcard drivers may allow linking by loopback, (What you hear, Stereo Mix)     Here is my setup PSDR, VAC, WSPR http://sites.google.com/site/g4zfqradio/softrock-wspr-psdr-and-vac 

Some report trouble with V 4.10, try V 4.09. This could be due to the way it is configured. VAC setup  http://www.youtube.com/watch?v=w4FsuLidTwA for full instructions on setting up your VAC. 

This page gives some hints for VAC setup, it is much the same whatever software is actually used. http://www.genesisradio.com.au/yt1dl/index.shtml http://www.genesisradio.com.au/yt1dl/vac.shtml with digital modes. Robby's starter page http://www.wb5rvz.com/sdr/common/02_common.htm

3 Audio files to test software without a SDR Most, if not all, SDR programs can play back these files that have been previously recorded. It is also possible to record your own if you DO have an SDR.  Many use this technique to analyse a range of frequency in detail.

You may get used to the software before it is connected to the SDR.. Written for GSDR but essentially for all software. "The initialization and start GSDR with your sound card and PC setup is very simple. First step is use recorded I/Q file download from Genesis site [ http://www.genesisradio.com.au/G40/ ] my file from ARRL CW contest 2009 for test . If you have sound card with low sample rate 48kHz find some file at Internet [Some below] After GSDR is working you can go to Genesis hardware connection.Tasa YU1LM/QRP"

   Flex Radio website www.flex-radio.com . If you go to their Support and then Downloads you can find example I-Q files. File Category Any - Audio IQ.  I believe that there are DRM, CW and SSB files there. 

"There are two 600Mb files on my website <  http://home.ict.nl/~fredkrom/pe0fko/IQRec/  > One CW contest and one SSB  contest, lot of signals. 73, Fred PE0FKO"
Another, shorter wav file (compressed with WINZIP) is also available at: http://www.wb5rvz.com/sdr/resources/WAV_files_short.zip           http://www.sm5bsz.com/rf_library.htm  Mainly examples of QRM etc but some others.

Listen to SDR via the internet     http://sdrspace.com/   (Download the Console to listen) ..  Or setup your own server?   A full spectrum view http://hfspectrum.net/  and RX.  There are more, links change... search.
