      A bit more, Brien... on reading, I see you asked about RX muting as well...

      My solution to that is less than elegant.  I get quite a lot of muting from the antenna switching process but certainly not total... my choices are to mute the audio from computer via the software.. they all have a 'mute' button or in my case I a have a keyboard with audio control buttons on it...one push of a button will mute any audio from RX while transmitting even though there is still RF being detected.  When in CW mode I like hearing the keying monitor on the ICOM so I have run a cable from the earphone jack to a 'duplex' jack on the audio interface... with earphones when un-muted I hear the Softrock but when I am transmitting I will hear the keying monitor on the ICOM.  BTW... once in a while I decide I don't need the panadapter and just want to listen to the ICOM as it was intended... because the Elad switch is set up to default to the ICOM when the switch is not powered up (a safety feature), all I need do is turn off the DC to the Softrock and switch and the '756 Pro II' then has full control.  Sometimes, I have found that the signals are actually  better under these circumstances as well!

      PS: I failed to mention that I use either a G5RV for 160-10 meters or a three element 17 meter beam as my antennas. Since neither of these is naturally tuned except on 160 and 17 meters, I use a manual Tokyo Hy-Power antenna couple in the main antenna line which serves to tune the signals to both the ICOM and the Softrock. I turn off the auto tuner on the ICOM and find that I get much better signal levels on the Softrock by using a tuner ahead of it than with just a straight run from the antennas.

      Don, you will probably need to narrow down your inquisitive mind a bit for us. You will get many and varied answers to your questions, I suspect.

      It will be helpful to know what your starting points are: What Softrock kits do you have? What commercial rigs do you currently operate and what bands/modes/power levels do you wish to work eventually.

      In my case I own several SR kits but recently I have experimented with using an Ensemble RX (General Coverage HF RX) in conjunction with an IC-756 Pro II. The sound interface in use much of the time is an FA-66 Firewire interfaced high end unit with capacity for 2X inputs and outputs, of which I use only one in the installation described. (You will need to use some sort of stereo input to a sound device to allow the Softrock to work properly. There are many options for this.)

      I also use an Elad RF sensitive relay which will switch the antenna in use between the ICOM and the Softrock depending upon whether I am TXing or RXing at the moment.  I also use a home built 'DEO Receiver Guard' ahead of the Softrock for some added protection.

      So far I have had no problems using this arrangement with 'HDSDR' and 'SDR Radio Console' as the receiving software at 100 watts and I have tested it on every amateur band.  Both programs will allow you to connect via CI-V CAT control with your commercial rig.

      With this configuration I am able to use the SDR receiver on the computer (normal PC Desktop with Win 7, 64 bit) to see 100 KHz of the band in use on the software panadapter but take advantage of the 100 watt output from the ICOM when transmitting. You will find Softrock kits used to capture the 'IF' signals from nearly any RX/TX or RX available to do something similar.

      You will  be wise to take time to read our archived posts and files sections to be generally familiar with what is available and what problems/solutions others have come up with and for the most part resolved.  Also use Google and some of the common key words to find additional information and sites for software downloads and hardware alternatives.

      And this is just a start... welcome to the group... I am sure will find here what you came looking for and soon you will be enjoying the best thing to come along since the triode (Hmmm.. my speller does not even know that word!) vacuum tube!

High quality A/D and D/A converters can be quite expensive, but as it turns out, most of us have low cost A/D and D/A convertors built into our PCs in the form of a sound card. Also, there are well defined programming interfaces and USB-based protocols for dealing with sound cards, so this is why a lot of the low cost experimentation around SDR is sound-card based.

            Bruce,

            An ASIO driver is planned.
            Steinberg's ASIO is prefered since it is the industry standard for low latency high performance streaming.
            As it is today, USB2SDR with the PowerSDR-IQ gives 96KHz and 192KHz on 32bit with 4 input channels and 4 output channels concurrently for XP/Vista/W7.
            The same specs will be provided from the ASIO hopefully this way you'll have more application options.

            73,
            Christos SV1EIA

              Christos,

              I've been following this and have tried to follow the links to locate pricing and ordering information, but haven't been able to locate it. Can you please tell me the price, availability and ordering information for the usb2sdr?

              Thanks,
              Gary

              Bruce,

              An ASIO driver is planned.
              Steinberg's ASIO is prefered since it is the industry standard for low latency high performance streaming.
              As it is today, USB2SDR with the PowerSDR-IQ gives 96KHz and 192KHz on 32bit with 4 input channels and 4 output channels concurrently for XP/Vista/W7.
              The same specs will be provided from the ASIO hopefully this way you'll have more application options.

              73,
              Christos SV1EIA

                Hi Gary,

                Yes, USB2SDR is available right now.
                The cost is 195 Euro
                Info on the board can be seen here
                -> http://www.wb5rvz.com/usb2sdr/index.htm
                -> http://www.wb5rvz.com/usb2sdr/Installation.htm
                -> http://groups.yahoo.com/group/powersdr-iq/files/USB2SDR%20Guide/

                Performance measurements of homebrew rigs with the USB2SDR are in the
                powersdr-iq Yahoo! group files section together with user success stories
                -> http://groups.yahoo.com/group/powersdr-iq/files/

                USB2SDR requires a specific PowerSDR-IQ version (and drivers)
                which is available here
                -> http://code.google.com/p/usb2sdr/downloads/list
                the preferred operating system is W7.

                Currently the USB2SDR has been succesfully operated on these homebrew rigs giving full RxTx capability, SoftRock(with USBtoI2C), Ensemble, UHFSDR, Lima-SDR, FA-SDR

                I hope the above give you a clear picture.

                If you are interested, PM me (sv1eia at gmail.com) for payment options or any additional information.

                73,
                Christos SV1EIA

                Happy to note that. Thanks, Christos. I do like your interface except for the restriction mentioned. Have not actually used it yet for TX but I am sure it

                  Happy to note that. Thanks, Christos.  I do like your interface except for the restriction mentioned.  Have not actually used it yet for TX but I am sure it performs well there too.

                  Bruce,

                  An ASIO driver is planned.
                  Steinberg's ASIO is prefered since it is the industry standard for low latency high performance streaming.
                  As it is today, USB2SDR with the PowerSDR-IQ gives 96KHz and 192KHz on 32bit with 4 input channels and 4 output channels concurrently for XP/Vista/W7.
                  The same specs will be provided from the ASIO hopefully this way you'll have more application options.

                  73,
                  Christos SV1EIA

                    This is unsolicited and offered in respect...  Christos' has created a winner here. The board is very professionally done, easy to hook up (at least with regard to RX which is all I have done so far) and works flawlessly with the version of PSDR available for the board.  The specifications/preformance appear to be as good or better than I get with my FA-66 USB audio interface.  We are still looking for a template to drill the holes for I/O sockets but I did locate a suitable, metal case for the project recently and will be mounting. Details on that in the future.  As an added bonus you will have the satisfaction of contributing to the part of the Greek economy!

                    Respectfully,

                    Bruce, K2BET

                    Hi Gary,

                    Yes, USB2SDR is available right now.
                    The cost is 195 Euro
                    Info on the board can be seen here
                    -> http://www.wb5rvz.com/usb2sdr/index.htm
                    -> http://www.wb5rvz.com/usb2sdr/Installation.htm
                    -> http://groups.yahoo.com/group/powersdr-iq/files/USB2SDR%20Guide/

                    Performance measurements of homebrew rigs with the USB2SDR are in the
                    powersdr-iq Yahoo! group files section together with user success stories
                    -> http://groups.yahoo.com/group/powersdr-iq/files/

                    USB2SDR requires a specific PowerSDR-IQ version (and drivers)
                    which is available here
                    -> http://code.google.com/p/usb2sdr/downloads/list
                    the preferred operating system is W7.

                    Currently the USB2SDR has been succesfully operated on these homebrew rigs giving full RxTx capability, SoftRock(with USBtoI2C), Ensemble, UHFSDR, Lima-SDR, FA-SDR

                    I hope the above give you a clear picture.

                    If you are interested, PM me (sv1eia at gmail.com) for payment options or any additional information.

                    73,
                    Christos SV1EIA
