      I've spent the past months adding a DelSig directly to the RXTX
      Ensemble. I used a Cypress PSoC 3 and a PCM3060 in place of the AVR
      and flipflop. These are SSOP packages so they don't need any skills
      beyond what we need for Tony's SoftRock. Perhaps a bit more patience
      is all.

      It's working well enough to be fun and useful to others so I made some kits:
      http://ae9rb.com

      I expect a little friction with software compatibility since hamlib
      looks for www.obdev.at in the USB vendor name. Anything that uses
      CFGSR or its ExtIO should work fine. HDSDR works great! I've also
      successfully tested with DSP Radio (Mac) and SDR#.

        Imagine a RXTX Ensemble that doesn't need a separate sound card. It
        should be quite useful for the many of us who use laptops, Raspberry
        Pis, Beaglebones, etc.

          Hi David,

          I do not understand why I did not receive this. Your right it is here on the web interface but didn't get sent to my email program. I wonder how many other messages I have missed.

          Back to the matter at hand.

          So does this show as a sound card per se? With the drivers I wonder if it will work with the CWSKimmer software. What is the bandwidth? 96kHz, 192kHz? I would liek to give one a try and see how it would work. Could you forward me the information on obtaining your modification?

          Thank you very much,

            Hi Tim,

            CWSkimmer seems to work. The audio output is not in phase and will
            crack and pop, but it does this on any sound card I try so it doesn't
            appear to be a Peaberry issue.

            Because the sound is 24-bit and there are effectively two sound cards
            in the Peaberry (7 channels), USB bandwidth dictates the limit to be
            48kHz. If you made yourself some custom firmware that disabled the
            mic and speaker, you could probably get things running at 96kHz.

            All the specs and more are documented on GitHub where you can find the
            source code and schematics for adapting to your own projects.
            https://github.com/ham21/peaberry

            It's not really a modification. I wanted an inexpensive SDR with easy
            to find parts that give a perfectly flat frequency response. This
            would have required too many mods on a standard SoftRock for my taste.
            So I just integrated everything into one board.

              I subscribe to a handful of Yahoo groups. I don't know why but I seem to
              miss about 5% of postings.

              One plausible explanation is that some of Yahoo's servers are
              blacklisted and emails from those servers are filtered out by ISP's fire
              walls and will only make it part way from there to you (or me).

              I haven't been able to validate that however. I just know that I don't
              get every posting but the number is small enough that sooner or later a
              posting from a thread will make it through so that in the end I really
              don't miss much if anything save for the occasional single posting.

              cheers, Graham ve3gtc

              I took some screenshots comparing a SoftRock RXTX on an iMic with the
              Peaberry (essentially a SoftRock with a PCM3060). Consider yourself
              lucky if you haven't had to hunt for a decent USB audio device and
              cables.

              I've been playing with WSPR. Attached is a map of the stations I
              picked up in the past 24 hours with a 20m attic dipole. Although WSPR
              uses hamlib, which still needs a small patch, you can use CFGSR to
              manually set the LO frequency for now.

                      This is beautiful work! Thanks for working so hard and sharing this with the community!

                      Do you think there would be any value in creating a PCB with the PCM3060 and CYBC3XXX only? I'd love to use your solution to interface with my existing Softrock radios.

                      I am currently using Christos' USB2SDR for this purpose but there are instances where I'd prefer to use applications other than the PowerSDR software.

                      Thanks again for doing this.

                        Thanks Joe,

                        When I first started this project I wanted to put a DelSig directly on
                        a Raspberry Pi. But they decided not to put the I2S lines on the
                        expansion header. Later, I thought I would make a board that would
                        interface with the DIP8 of a SoftRock. But I came upon a clever way
                        to provide two full sound cards with just the one PCM3060 and the
                        thought of making a fully integrated transceiver consumed me. So I
                        made that happen.

                        I have a UHFSDR sitting here that needs a good interface as well. So
                        I'm personally vested in making a cheaper, non-powersdr, interface
                        for SDR. I'm just not sure what features to include. Too many build
                        options and you end up with complicated junk, too few and it's just a
                        DIY sound card.

                        So let me toss it out to you all. Let's start with the following feature set:

                        * Bus-powered USB (no power connector)
                        * 24-bit 48kHz and 96kHz support
                        * One stereo-in and one stereo-out
                        * Si570 control (pe0fko command set)

                            Thanks Joe,

                            When I first started this project I wanted to put a DelSig directly on
                            a Raspberry Pi. But they decided not to put the I2S lines on the
                            expansion header. Later, I thought I would make a board that would
                            interface with the DIP8 of a SoftRock. But I came upon a clever way
                            to provide two full sound cards with just the one PCM3060 and the
                            thought of making a fully integrated transceiver consumed me. So I
                            made that happen.

                            I have a UHFSDR sitting here that needs a good interface as well. So
                            I'm personally vested in making a cheaper, non-powersdr, interface
                            for SDR. I'm just not sure what features to include. Too many build
                            options and you end up with complicated junk, too few and it's just a
                            DIY sound card.

                            So let me toss it out to you all. Let's start with the following feature set:

                            * Bus-powered USB (no power connector)
                            * 24-bit 48kHz and 96kHz support
                            * One stereo-in and one stereo-out
                            * Si570 control (pe0fko command set)
                            * a dip8 for ice of the avr
                            * some .100" pins for developers to play with the extra PSoC GPIOs

                            What would you add or take away? Kit or factory assembly?

                                          I had a dabble with PSOC years ago, but never found a worthy project for it. Your implementation looks brilliant and I have ordered a kit today to complement my UHFSDR and Softrock TxRx kits.
                                          I look forward to playing with the PSOC code. It doesnt say on your website, but presumably the CY8C3XXX is preloaded with code?

                                          Thanks Tony. The PSoC has been programmed and a SWD jack is included so you can upgrade and play if you have a MiniProg3 or other SWD programmer. It s pretty

                                            "Years ago" may mean that you were dabbling with a PSoC 1, which is
                                            less capable and perhaps why you couldn't find a worthy project.

                                              Do you think there would be any value in creating a PCB with the PCM3060 and CYBC3XXX only? I'd love to use your solution to interface with my existing Softrock radios.

                                              I've been giving this more thought and here's what I came up with. The cheaper PSoC won't run 96kHz. The product will not be inexpensive.  Nearly everyone who has a SoftRock has already solved the sound card problem. many for less than $5. It would cost more to buy a RXTX, PSoC-SDR-sound-card, and cables than to buy a Peaberry -- and you'll end up with less performance and no mic pre-amp or speaker hookup. Perhaps the most important reason is that of the 7000+ people on this list, only 1 said they would buy the device.

                                              Maybe I'm wrong and there's a significant demand for a ~$50 24-bit 48/96kHz USB sound card board. Unless there's an overwhelming response for me to produce this, I'll stick to making complete radios.
