      Hi.  Been playing around with my Softrock Lite II Receivers and Linux.  I am trying to build a WebSDR server.  

      While I am familiar with Linux, have been using it a long time, building web servers, email servers, DNS servers, File/Print Servers, Firewall boxes, yada yada yada, something that I have NEVER put much time into was the Sound portion of Linux.  I am totally lost.  In the past when I worked on a linux server if the sound worked at all, I just said "cool, that's neat that it actually worked, I am quite surprised L O L ", and that was my extent of concern with the SOUND portion of Linux.  I am quickly finding out it's a M E S S.

      I have OpenSuSE 12.3 with ALSA.

      I have a whole STACK of sound cards that I have been experimenting with.  What I need is 2 capture devices, PER CARD, @ 192KHz sample rate.  I have yet to find an y card that will do this with my stock install of ALSA, I only get 1 capture device per card, on the cards that do 192Khz Capture.  I DO however have 2 x 96K capture devices working on the cheezy builtin audio, but I want 2 x 192K per Card, and in the end total of 3 cards, 1 PCIe and 2 PCI.

      What's in the machine right now: 

      Card 1  Builtin Audio ALC662
      Card 2  Xonar DX (PCI E)
      Card 3  SB Audigy SE (PCI) (SB0570L4, yes does 192K capture x 1 device despite what specs say, bought it new at Best Buy last week)

      Output of "cat /proc/asound/cards"

      Out of all those capture devices listed, the only ones that actually work, NO MATTER how I set the switches/controls in alsamixer are:

      hw:0,0,0
      hw:0,2,0
      hw:1,0,0
      hw:2:0:0

      The CA0106 card lists a bunch of capture devices but only one works, and it's my understanding that on this card (SB0570) that you can only use 1 capture at a time, even in Windows.

      The DX (Xonar DX PCIe card) SHOULD work at 192K x 2 for capture.  But the only device that works is the one labeled as "Multichannel".  However, no matter how you try to put the ALSA device name in WebSDR, it will only capture on the 0,0 device.  If you try 1,0 it just has a solid signal all the way across.   This card has an AUX input on the board that I have ran a 1/8 stereo jack to a back plate on the computer to connect it, and it IS done correctly, but does not work, assumingly because the ALSA has no capture device listed for it.  How do I enable it?

      Builtin Audio ALC662 has 2 capture devices turned on in alsamixer and both of those work just fine at 96K each.

      So can anyone help?  Surely someone here knows a lot about Linux Sound, I do not know anything about it as my experience is limited to "Server" duties when it comes to Linux, never cared whether the sound worked or not.  Sid?  Any help?

      The other cards I have laying around only seemed to work at 24 or 48Khz, even if they were spec'd to 96K.  Any help with that?  Firmware limitation of the card?  Setting in ALSA? Driver issues?  The other cards list:

      Sound Blaster Audigy 2 ZS (SB0350 (shows SB0353 installed) - only worked at 48Khz and seemed to only have mono microphone/line in input, mirrored on both sides of band.  This card is THX certified and should work at 96Khz and all inputs should be Stereo, I am assuming ALSA is misconfigured POS and that's why this card didn't work properly, it's rated for like 108dB or SNR, and would be a nice card if ALSA would cooperate with it.

      Sound Blaster SB0160 -  Old Premium (non-value edition) Audigy 1 card, decent SNR, supposed to be good for 48 or 96K x 2 inputs but could not get ANYTHING to work on this card, worked fine in a Windows box.

      Sound Blaster Audigy SE (SB0570) (without the L4) old card -- Old Audigy SE card, looks IDENTICAL to my brand new Audigy SE card, but does not work right, capture in 192K shows about 4-8 slim sections that all mirror each other.  I think the only way capture seemed to work right on this card was at 24K or something really low, should be same as my newer Audigy SE card, but for some reason doesn't work the same, no matter the settings in alsamixer.

              I received it without problems. I use these cards on 2 boxes but I only need one for the DDC/DUC openHPSDR Hermes and HiQSDR rigs which only need Mic/Speakers.

                I haven't looked seriously at webSDR, thought it only supported commercial rigs.

                I use ghpsdr3-alex on openSUSE and Kubuntu -- http://napan.ca/ghpsdr3/index.php/Main_Page
                It supports HPSDR including openHPSDR Hermes/ANAN, Flex-1000,Softrock, UHFSDR, Microtelecom Perseus, SDR-iq, HiQSDR, Ettus Research USRP and rtl-sdr DVB-T dongles.
                There is also a branch supporting USB2SDR+Softrock.

                Allows access via the LAN or internet for RX and TX (user and password protected), QtRadio is the PC client and also glSDR from Google Play store on Android tablets and mobile phones.

                  Sid.  Can you post output of "arecord -l"  so I can see what your capture devices look like?  Have you used more than one at a time on a single card?  That is what I am concerned with.  I am not interested in changing software from WebSDR to anything else at this time, not using this machine like I would a HDSDR XP Machine, using this to provide a service, WebSDR.  Also it's nice to monitor all bands at one time in a single window from any of the computers on my network.

                  Thanks,

                  Hi.  Been playing around with my Softrock Lite II Receivers and Linux.  I am trying to build a WebSDR server.  

                  While I am familiar with Linux, have been using it a long time, building web servers, email servers, DNS servers, File/Print Servers, Firewall boxes, yada yada yada, something that I have NEVER put much time into was the Sound portion of Linux.  I am totally lost.  In the past when I worked on a linux server if the sound worked at all, I just said "cool, that's neat that it actually worked, I am quite surprised L O L ", and that was my extent of concern with the SOUND portion of Linux.  I am quickly finding out it's a M E S S.

                  I have OpenSuSE 12.3 with ALSA.

                  I have a whole STACK of sound cards that I have been experimenting with.  What I need is 2 capture devices, PER CARD, @ 192KHz sample rate.  I have yet to find an y card that will do this with my stock install of ALSA, I only get 1 capture device per card, on the cards that do 192Khz Capture.  I DO however have 2 x 96K capture devices working on the cheezy builtin audio, but I want 2 x 192K per Card, and in the end total of 3 cards, 1 PCIe and 2 PCI.

                  Out of all those capture devices listed, the only ones that actually work, NO MATTER how I set the switches/controls in alsamixer are:

                  hw:0,0,0
                  hw:0,2,0
                  hw:1,0,0
                  hw:2:0:0

                  The CA0106 card lists a bunch of capture devices but only one works, and it's my understanding that on this card (SB0570) that you can only use 1 capture at a time, even in Windows.

                  The DX (Xonar DX PCIe card) SHOULD work at 192K x 2 for capture.  But the only device that works is the one labeled as "Multichannel".  However, no matter how you try to put the ALSA device name in WebSDR, it will only capture on the 0,0 device.  If you try 1,0 it just has a solid signal all the way across.   This card has an AUX input on the board that I have ran a 1/8 stereo jack to a back plate on the computer to connect it, and it IS done correctly, but does not work, assumingly because the ALSA has no capture device listed for it.  How do I enable it?

                  Builtin Audio ALC662 has 2 capture devices turned on in alsamixer and both of those work just fine at 96K each.

                  So can anyone help?  Surely someone here knows a lot about Linux Sound, I do not know anything about it as my experience is limited to "Server" duties when it comes to Linux, never cared whether the sound worked or not.  Sid?  Any help?

                  The other cards I have laying around only seemed to work at 24 or 48Khz, even if they were spec'd to 96K.  Any help with that?  Firmware limitation of the card?  Setting in ALSA? Driver issues?  The other cards list:

                  Sound Blaster Audigy 2 ZS (SB0350 (shows SB0353 installed) - only worked at 48Khz and seemed to only have mono microphone/line in input, mirrored on both sides of band.  This card is THX certified and should work at 96Khz and all inputs should be Stereo, I am assuming ALSA is misconfigured POS and that's why this card didn't work properly, it's rated for like 108dB or SNR, and would be a nice card if ALSA would cooperate with it.

                  Sound Blaster SB0160 -  Old Premium (non-value edition) Audigy 1 card, decent SNR, supposed to be good for 48 or 96K x 2 inputs but could not get ANYTHING to work on this card, worked fine in a Windows box.

                  Sound Blaster Audigy SE (SB0570) (without the L4) old card -- Old Audigy SE card, looks IDENTICAL to my brand new Audigy SE card, but does not work right, capture in 192K shows about 4-8 slim sections that all mirror each other.  I think the only way capture seemed to work right on this card was at 24K or something really low, should be same as my newer Audigy SE card, but for some reason doesn't work the same, no matter the settings in alsamixer.

                    Sid.  Can you post output of "arecord -l"  so I can see what your capture devices look like?  Have you used more than one at a time on a single card?  That is what I am concerned with.  I am not interested in changing software from WebSDR to anything else at this time, not using this machine like I would a HDSDR XP Machine, using this to provide a service, WebSDR.  Also it's nice to monitor all bands at one time in a single window from any of the computers on my network.

                    Thanks,

                    Out of all those capture devices listed, the only ones that actually work, NO MATTER how I set the switches/controls in alsamixer are:

                    hw:0,0,0
                    hw:0,2,0
                    hw:1,0,0
                    hw:2:0:0

                    The CA0106 card lists a bunch of capture devices but only one works, and it's my understanding that on this card (SB0570) that you can only use 1 capture at a time, even in Windows.

                    The DX (Xonar DX PCIe card) SHOULD work at 192K x 2 for capture.  But the only device that works is the one labeled as "Multichannel".  However, no matter how you try to put the ALSA device name in WebSDR, it will only capture on the 0,0 device.  If you try 1,0 it just has a solid signal all the way across.   This card has an AUX input on the board that I have ran a 1/8 stereo jack to a back plate on the computer to connect it, and it IS done correctly, but does not work, assumingly because the ALSA has no capture device listed for it.  How do I enable it?

                    Builtin Audio ALC662 has 2 capture devices turned on in alsamixer and both of those work just fine at 96K each.

                    So can anyone help?  Surely someone here knows a lot about Linux Sound, I do not know anything about it as my experience is limited to "Server" duties when it comes to Linux, never cared whether the sound worked or not.  Sid?  Any help?

                    The other cards I have laying around only seemed to work at 24 or 48Khz, even if they were spec'd to 96K.  Any help with that?  Firmware limitation of the card?  Setting in ALSA? Driver issues?  The other cards list:

                    Sound Blaster Audigy 2 ZS (SB0350 (shows SB0353 installed) - only worked at 48Khz and seemed to only have mono microphone/line in input, mirrored on both sides of band.  This card is THX certified and should work at 96Khz and all inputs should be Stereo, I am assuming ALSA is misconfigured POS and that's why this card didn't work properly, it's rated for like 108dB or SNR, and would be a nice card if ALSA would cooperate with it.

                    Sound Blaster SB0160 -  Old Premium (non-value edition) Audigy 1 card, decent SNR, supposed to be good for 48 or 96K x 2 inputs but could not get ANYTHING to work on this card, worked fine in a Windows box.

                    Sound Blaster Audigy SE (SB0570) (without the L4) old card -- Old Audigy SE card, looks IDENTICAL to my brand new Audigy SE card, but does not work right, capture in 192K shows about 4-8 slim sections that all mirror each other.  I think the only way capture seemed to work right on this card was at 24K or something really low, should be same as my newer Audigy SE card, but for some reason doesn't work the same, no matter the settings in alsamixer.

                        Larry,

                        I found JP5 open, soldered it and signals were coming in.
                        there is one USB ground for the SI570 and another ground for the QSD, bandswitching is effected  by optocouplers.
                        However you have to connect these 2 grounds in order to switch on the red LED to show the unit is powered up.
                        QSD power is from USB 5 V via a Mosfet, thus resulting QSD ICs to be powered by 4,4V only.
                        SI570 pin 6 however is powered with 5 V direct from USB. (see datasheet ! )
                        D4 could not be found on board,
                        6 -15V supply is not populated and somewhat unclear.
                        I have asked the producers some questions, no reply so far has been received. QSE would have been nice.
                        Functionality is limited to receive.

                          The schematic I have shows the Si570 pin 6 powered from 3V3, I hope this is true!
                          4V4 is fine, I have found Softrocks work down to about 2V5.

                            The voltage drop across a MOSFET should not be 0.6 volts as they do not have a PN junction for the current to flow through like a BJT does.  The channel resistance with the FET turned on should be almost nothing and no noticeable voltage drop should be observed.

                              On my 3dB board I just measured 5,04 V between pin3 and pin6 of the SI570. board is USB supplied from desktop.
                              Pin4 is 2,48V, SI570 is working, but I feel pin6 must get 3,3V.
                              My board is working, but I had expected to receive a fully tested board plug and play with no open connections, such as for example JP5 in my case.
                              I compare it to the SR63 board from yoyodyne, which is a kit, with more features.

                                Really 5V???
                                This should not be, 3V3 is the maximum specified voltage for any Si570.
                                It may not last long at 5V! Unless there is a new version for 5V, which I doubt.

                                  Hello Garry,

                                  And I thought I was having problems with my HF-3dBSDR receiver. :-)

                                  The hardware seems to be functional, but getting Windows 8, and the GUI tuning
                                  software (HDSDR) correctly configured (while learning its operation), seems to
                                  be an issue for me at present. The software is functional with the
                                  RTL2382U/R820T Ezycap dongle, but this is the first time I have used the sound
                                  card for SDR. I'm seeing lots of image signals and little else at the moment.
                                  I've been attempting to understand HDSDR's "RF front-end frequency options &
                                  Calibration" function, but although I can hear WWV fine on the Icom, I'm not
                                  able to find it in the HDSDR/HF-3dBSDR receiver ...

                                  I'm considering moving the HF-3dBSDR receiver audio output from the Mic jack to
                                  the external USB "sound card." as mentioned in the FAQ.

                                  Is this grounding versatility documented anywhere? There's one line on the
                                  subject in the FAQ <http://3dbsdr.com/faq.php>:

                                  "Our board has traces to cut to enable different grounding isolation
                                  schemes."

                                  And I find no mention of grounding on the HF-3dBSDR schematic:
                                  <http://3dbsdr.com/downloads/hfhdr_windows/sdr2.pdf>.

                                  The red LED already lights when my HF-3dBSDR receiver is plugged into the USB
                                  port.

                                  Data sheet? What data sheet? Are you referring to the SI570 data sheet? Can
                                  you e-mail a copy to me or provide a link? All I received in my HF-3dBSDR
                                  receiver shipment was the HF-3dBSDR receiver board, no documentation nor
                                  software.

                                  Have you posted your questions to the 3dB Software Defined Radio Forum?
                                  <http://forum.3dbsdr.com/>. It's worth a try, right?

                                  QSE, as well as so many other functions, would be nice, but not if they
                                  affected price. I'm planning on using the HF-3dBSDR receiver to provide a
                                  bandscope for use with my IC-7800 through CAT software (wish me luck).

                                  Best regards,
                                  Larry

                                  Larry, right beside the BNC input connector there is a JP5 , which I had to solder to connect the BNC to the input transformer. If not soldered ( connected )

                                    Larry,
                                    right beside the BNC input connector there is a "JP5", which I had to solder to connect the BNC to the input transformer.
                                    If not soldered ( connected ) BNC is open, kindly check.
                                    As for the grounding I am asking myself, why a 4 layer board has been made, if you must solder JP2 and thus connect USB ground with the QSD ground. I could not find any docu on this grounding versatility.
                                    I will cut the trace of pin6 of SI570 and connect same to the 3,3 V regulator.
                                    SI570 datasheet is made by Silicon Labs, you get the datasheet from their homepage.
                                    If I switch in filter 2 instead of filter 1 for 40 meters, there is maybe some dB difference, but you cannot expect steep filters from 
                                    just 1 parallel and 2 serial resonances, I also get lots of images . I use CFGSR and Rocky3.7
                                    I wish you luck and hope you get the signals coming in and SI570 working,

                                      Gerry,

                                      JP5 should not be connected unless you are never going to use a proper antenna.
                                      The BNC ground is normally made through an ATU or the grounded coax of the antenna system.
                                      If you want to try a random wire (not reccommened) make a temporary connection.

                                      >I will cut the trace of pin6 of SI570 and connect same to the 3,3 V regulator.
                                      SI570 datasheet is made by Silicon Labs, you get the datasheet from their homepage.

                                      If the Si570 has 5V on it then I would at least ask for a replacement board. It's probable that its life is already reduced. 50%

                                      And you have said the 5V line is 4V4. I had thought maybe that was due to low USB voltage and some drop but if you have 5V on the
                                      Si570 that points to something badly wrong elsewhere.
                                      It was not sold as a faulty board that needed repair?
                                      I'm wondering if you should get your money back and go for an established unit like the Softrock....

                                        software (HDSDR) correctly configured (while learning its operation), seems to
                                        be an issue for me at present. The software is functional with the
                                        RTL2382U/R820T Ezycap dongle, but this is the first time I have used the sound
                                        card for SDR. I'm seeing lots of image signals and little else at the moment.
                                        I've been attempting to understand HDSDR's "RF front-end frequency options &
                                        Calibration" function, but although I can hear WWV fine on the Icom, I'm not
                                        able to find it in the HDSDR/HF-3dBSDR receiver ...

                                        Larry,

                                        to calibration and other pages. As this is essentially a Softrock the "Calibration A" should work.

                                        the external USB "sound card." as mentioned in the FAQ.

                                        A soundcard SDR MUST go into a stereo Line input. Sometimes when there is only a mic input it may be configured as a stereo line
                                        input.

                                        "Our board has traces to cut to enable different grounding isolation

                                        And I find no mention of grounding on the HF-3dBSDR schematic:
                                        <http://3dbsdr.com/downloads/hfhdr_windows/sdr2.pdf>.
                                        Have you posted your questions to the 3dB Software Defined Radio Forum?
                                        <http://forum.3dbsdr.com/>. It's worth a try, right?

                                        Grounding is really a matter of experimenting. Until it works I'd ignore that.
                                        It is a pity there seems to be no support. Ready-made SDRs are often bought by beginners in SDR.

                                          Alan,

                                          thanks for your kind comments on my 3dB board.
                                          I had already thought to return it, but strangely these sellers dont even give me an answer to my questions.
                                          I am sure our remarks are justified.
                                          I will just write it off, 100 US out the window. Too much troubles sending the board around the globe.

                                          I have an SR63 from Yoyodyne and I will also assemble the Yoyodyne widget, all components ready to populate the board.
                                          And I have a FiFi from Funkamateur with  Bonito Spectroscope software, which works very nicely and I have a MOBO4.3 kit ready to be assembled.
                                          I also made an SDR QSD based on LT6517 quadrature demodulator, which goes boyond 1 GHz.
                                          Last year I made a JUMA type RX and the SRTOGO is waiting for integration.

                                          I feel this is enough projects waiting to be finished and I am happy to see the performance of the different units.
                                          I did not go for Tony s Softrock, there is no full shortwave band coverage, I like the WB6DHW bandpassfilter, nice perormance even with the SMD inductors.

                                          So I will keep on swinging a hot soldering iron and hopefully I ll be on the air again some day.

                                          Best regards, 73,
                                          Gerry, OE6HGG, Graz, Austria

                                          Gerry,

                                          JP5 should not be connected unless you are never going to use a proper antenna.
                                          The BNC ground is normally made through an ATU or the grounded coax of the antenna system.
                                          If you want to try a random wire (not reccommened) make a temporary connection.

                                          >I will cut the trace of pin6 of SI570 and connect same to the 3,3 V regulator.
                                          SI570 datasheet is made by Silicon Labs, you get the datasheet from their homepage.

                                          If the Si570 has 5V on it then I would at least ask for a replacement board. It's probable that its life is already reduced. 50%
                                          overvoltage on a device that runs hot at 3V3???
                                          And you have said the 5V line is 4V4. I had thought maybe that was due to low USB voltage and some drop but if you have 5V on the

                                                I talked with the builder and he said that an error in the schematic is the

                                                I am assuming you have revision 1. We have the next batch of revision 2
                                                boards coming in in a week and it will be a day or three to build one. If
                                                you like, we can swap it out for free. Just return it to us at the address
                                                sent earlier. Your rma number is XX. look on the back of yours and see if
                                                you have a serial number sticker. If you dont have a serial number sticker
                                                it means you managed to buy a prototype, possibly my own personal sdr. If
                                                you do have a serial number I would like to contact the serial numbers
                                                close to it to see if they have the same problem. There were 50 Rev 1
                                                boards made.

                                                The builder says he knew of the over voltage but didnt see any performance
                                                problems so he passed the quality check on them and changed the board
                                                design. I dont know if a shortened life cycle will be a result of this or
                                                if it results in more noise, but I will certainly test a rev 2 board vs a
                                                rev 1 board and tell you what I find.

                                                  Hello Garry,

                                                  The information you provided confirms that you have a Rev.A HF-3dBSDR receiver
                                                  too. Like you, I also found 5V on my Si570. What I want to know is, did yours
                                                  work like that, with 5V on the Si570? Or did you have to route 3.3 VDC to the
                                                  Si570 to get it to work?

                                                  You should find this message I received from 3dB today interesting (below).

                                                  I don't know if I should go through the trouble of sending mine back for
                                                  exchange for a Rev.2 board, or just cut and jumper.

                                                  Thanks for your help.

                                                  Best regards,

                                                  I talked with the builder and he said that an error in the schematic is the
                                                  cause of the improper voltage. This was fixed in revision 2 of the board so
                                                  I am assuming you have revision 1. We have the next batch of revision 2
                                                  boards coming in in a week and it will be a day or three to build one. If
                                                  you like, we can swap it out for free. Just return it to us at the address
                                                  sent earlier. Your rma number is XX. look on the back of yours and see if
                                                  you have a serial number sticker. If you dont have a serial number sticker
                                                  it means you managed to buy a prototype, possibly my own personal sdr. If
                                                  you do have a serial number I would like to contact the serial numbers
                                                  close to it to see if they have the same problem. There were 50 Rev 1
                                                  boards made.

                                                  The builder says he knew of the over voltage but didnt see any performance
                                                  problems so he passed the quality check on them and changed the board
                                                  design. I dont know if a shortened life cycle will be a result of this or
                                                  if it results in more noise, but I will certainly test a rev 2 board vs a
                                                  rev 1 board and tell you what I find.

                                                    Did you get the new board working? Was curious haven't heard anything back from you. The board I shipped you ran on my desk for 2 days and I used it to listen to many stations before we shipped to out to you.

                                                    Hello Garry,

                                                    The information you provided confirms that you have a Rev.A HF-3dBSDR receiver
                                                    too. Like you, I also found 5V on my Si570. What I want to know is, did yours
                                                    work like that, with 5V on the Si570? Or did you have to route 3.3 VDC to the
                                                    Si570 to get it to work?

                                                    You should find this message I received from 3dB today interesting (below).

                                                    I don't know if I should go through the trouble of sending mine back for
                                                    exchange for a Rev.2 board, or just cut and jumper.

                                                    Thanks for your help.

                                                    Best regards,
                                                    Larry

                                                    I talked with the builder and he said that an error in the schematic is the
                                                    cause of the improper voltage. This was fixed in revision 2 of the board so
                                                    I am assuming you have revision 1. We have the next batch of revision 2
                                                    boards coming in in a week and it will be a day or three to build one. If
                                                    you like, we can swap it out for free. Just return it to us at the address
                                                    sent earlier. Your rma number is XX. look on the back of yours and see if
                                                    you have a serial number sticker. If you dont have a serial number sticker
                                                    it means you managed to buy a prototype, possibly my own personal sdr. If
                                                    you do have a serial number I would like to contact the serial numbers
                                                    close to it to see if they have the same problem. There were 50 Rev 1
                                                    boards made.

                                                    The builder says he knew of the over voltage but didnt see any performance
                                                    problems so he passed the quality check on them and changed the board
                                                    design. I dont know if a shortened life cycle will be a result of this or
                                                    if it results in more noise, but I will certainly test a rev 2 board vs a
                                                    rev 1 board and tell you what I find.

                                                      there is one USB ground for the SI570 and another ground for the QSD, bandswitching is effected  by optocouplers.
                                                      However you have to connect these 2 grounds in order to switch on the red LED to show the unit is powered up.
                                                      QSD power is from USB 5 V via a Mosfet, thus resulting QSD ICs to be powered by 4,4V only.
                                                      SI570 pin 6 however is powered with 5 V direct from USB. (see datasheet ! )

                                                        did arrive, and I have made a preliminary test. Without question, this new
                                                        board works significantly better than the original defective one I received.

                                                        In the interim, while I was waiting for you to ship a functional board, I

                                                          Hi Jim,

                                                          Yes, the version 1A updated replacement HF-3dBSDR receiver board for the
                                                          defective one I ordered on August 24, 2013, and returned on September 11, 2013
                                                          did arrive, and I have made a preliminary test. Without question, this new
                                                          board works significantly better than the original defective one I received.

                                                          Sam Ammons:
                                                          We received your SDR and it is "not right".

                                                          In the interim, while I was waiting for you to ship a functional board, I
                                                          purchased a FiFi SDR receiver with preselector and integrated sound card in an
                                                          aluminum case here for nearly the same price here:
