SDR - SDR SOFTWARE
"Unofficial" AVR software may provide smooth tuning and automatic BPF switching with various software see http://home.ict.nl/~fredkrom/pe0fko/SR-V9-Si570/
ROCKY PROBABLY THE EASIEST SOFTWARE TO GET GOING. 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.
In message # 21692 Tony explains how to setup Rocky for 40 fixed frequencies. http://groups.yahoo.com/group/softrock40/message/21692 Or read it here with my notes added. A good description of Rocky's ini http://www.wb5rvz.com/sdr/RX_V8_3/Sw1Settings.htm
A MESSAGE FROM TONY TO HELP BEGINNERS WITH ROCKY.
"Please try the Rocky 3.6 software as a start in getting the v6.3 RXTX+Xtall board to play properly. [Or any SDR]
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.
The paddle input for use with Rocky is through the USB I2C interface board, connections K1, K2 and ground. Also on the USB I2C interface board is a PTT output that may be connected to the PTT I hole on the RXTX board so that Rocky controls RX/TX switching. The USB I2C board map shows the connections to the board.
I think if you will go carefully through the information Alex has posted on his website you will be able to get the RXTX board playing properly."
Problems with Rocky? Bruce, K2BET says he had troubles with USB control, maybe Rocky got corrupted when he used it with PSDR still running. He noted that uninstalling Rocky did not work as expected, the files were left in "Program Files" He found that deleting these then restored correct operation upon a fresh installation. (Maybe just deleting the Rocky.ini file would have rectified the problem?) Saving it will enable you to restore Rocky, maybe on another computer.
Look at some of the other software on Alex's site. It is not all free. CW Skimmer uses a SDR and displays and identifies all the CW signals in a bandwidth equal to the sample rate of your soundcard if the computer is fast enough! We are getting far too close to the totally automatic contest/DX catcher, where has actual operating gone?
FAROS (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
POWER SDR SEVERAL VERSIONS! Different ways to setup and use, look at the relevant help files! It is MORE VERSATILE, SLIGHTLY MORE SETUP OPTIONS, THEREFORE IT IS BETTER TO TRY THIS ONCE THE SOFTROCK IS WORKING.
PowerSDR-SR40 http://powersdr-sr40.sourceforge.net/ (PE1NNZ) couples a Softrock with a Si570 to enable control via a parallel port. (LPT) Look for other versions on the Yahoo group "when using the PowerSDR software for Softrock (Guido PE1NNZ) 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.
Christos SV1EIA's version http://code.google.com/p/powersdr-iq/ And the Yahoo group http://groups.yahoo.com/group/powersdr-iq/ ."Dear All, Another fresh version of the PowerSDR-IQ has just been uploaded to the downloads area http://code.google.com/p/powersdr-iq/downloads/list . This fresh one, is taking care of some issues in the previous version and 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.
There soon may be a version to control the Si570 by a serial port. .......A version with USB control via a Brainard board (Not Tony's or SDR Kits) is available....... Of course, like all SDR programs, Power SDR may be used with an independent Si570 controller. ......
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.
The version of PSDR at http://www.sdr-kits.net/USB/USB_Description.html 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. (See my USB control section 8) This PSDR also has the fixed audio frequency feature to make image rejection easier.
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
Flexradio download site for latest version of PowerSDR http://support.flex-radio.com/Downloads.aspx?fr=1
KGKSDR http://www.m0kgk.co.uk/sdr/index.php and his Yahoo group. http://groups.yahoo.com/group/kgksdr/ CW, SSB transmit with receive only for AM and FM
Winrad http://www.winrad.org/ a good RX only program. Alberto is giving up his development and will be releasing the source for others. October 23 the last Final Version is now released.
Keep another window on top of Winrad http://www.abstractpath.com/powermenu/ On the http://www.winrad.org/ site, a version in a moveable window by G3OQD.
Test version of Winrad usb_xtall frequency control DLL. http://212.254.198.33/ExtIO_si570_usb.zip place it in the Winrad folder, start Winrad and go to options - select input - si570 xtall usb. Cesco And a version for serial control.... http://212.254.198.33/extio_si570_serial.zip
Fred's DLL control USB frequency control AND BPF switching with the original ATTiny 45!! http://home.ict.nl/~fredkrom/pe0fko/ExtIO_Si570/ ExtIO_Si570 WinRad DLL will control the frequency setting of the SoftRock V9.0 over the USB port. It also manages the band pass filter if it is present and handle special frequency settings in WinRad for using the 2m module.
Winrad and auto BPF also other enhancements http://home.ict.nl/~fredkrom/pe0fko/ExtIO_Si570/ Cecil can provide a programmed AVR, you need to send him the software , or at least make sure he knows what you want on it! Or look above in Section 4 for some links for AVR programming.
