      If resizing has not been done the card you should be able to copy and reloaded on the 4GB card..
       
      You can check this by reading the card and see how much of the image was expanded onto the card. if it is less than 4GB you should be good to go!

      Appreciate the answers…  Interestingly, I had figured it out… One question, is there a way to copy from 8 GB card to a 4 GB card? I know I can go the other way ;-)

          You can use "gparted" in another linux box to resize up & down.

          However I've noticed so far that even if you shrink the partition
          can't get smaller image.    The Winimage makes image of the entire
          drive.  IE: if it's an 8 gig that's what we get. Will be pursuing
          this more as would like to shrink some down again. (for storage)

          " sudo apt-get gparted" or use synaptic package manager.
          Must use different machine,& of course get the right partition!:)

                While dd works great, take a minute and install dd_rescue (if you're on a Debian-derived linux, do "sudo apt-get install dd_rescue").  dd_rescue gives you progress updates and time estimates.  Functionally, it's the same, it just gives more feedback.

                To copy an image off of an SD card, you'll need to know which device it is and what you'd like to name the image file on your hard drive.  Assume that the SD card is /dev/sdb and you want to name the image file on your hard drive foo.dd.  Run the following command:

              sudo dd_rescue /dev/sdb foo.dd

              or if you prefer dd:

              sudo dd if=/dev/sdb of=foo.dd bs=4k

                After a wait, you'll have an image of your SD card on your hard drive called foo.dd.  That file is typically very compressable.  Use bzip2 -9 for maximum compression.

                To write an image onto an SD card, it's very similar.  Again, assume sdb and foo.dd:

              sudo dd_rescue foo.dd /dev/sdb
              or
              sudo dd if=foo.dd of=/dev/sdb bs=4k

                Note that you shouldn't guess what disk device the card is.  If you guess wrong (ie, /dev/sda), you'll write the image onto your hard drive rather than your SD card.  Errors are dangerous!

                If you have two SD card readers in your machine (say sdb and sdc), you can copy directly from one card to the other:

              sudo dd_rescue /dev/sdb /dev/sdc
              or
              sudo dd if=/dev/sdb of=/dev/sdc bs=4k

                This doesn't work for moving data between cards of different sizes.  If you dd a 4gig image onto an 8gig, you won't hurt anything, other than you'll only use half of the space on the 8gig card unless/until you expand the filesystem.  No harm done.  On the other hand, if you try to dd an 8gig image onto a 4gig card, you can cause yourself endless grief.  First of all, there's no guarantee that even if there's less than 4gig of data on the 8gig image that the data is at the "bottom" of the filesystem.  Your system will also see an 8gig partition on a 4gig device, causing all sorts of headaches.  The solution here is to mount the source device (for example, on /media/deadbeef) then partition, format, and mount the destination device ("sudo fdisk /dev/sd?", "sudo mkfs.ext? /dev/sd?", then "sudo mount /dev/sd?? /mnt").  Then you can copy the contents with something like rsync ("sudo rsync -av --delete /media/deadbeef/ /mnt/").  Again, don't just guess the values where the "?" are, you're guaranteed to hork things permanently).  Using rsync will work so long as the data from the larger card will fit in the available space on the smaller card.  If you don't have rsync on your system, you can do it the way we did it in the old days:

              cd /media/deadbeef/; find . -depth -print | sudo cpio -pdmuv /mnt/

                But that's pretty old-school. :D  Doing a recursive copy with cp may or may not preserve ownership and permissions, depending on the flags you provide.  And it won't copy special files (ie, files in /dev/, /proc/, etc).

                    While dd works great, take a minute and install dd_rescue (if you're on a Debian-derived linux, do "sudo apt-get install dd_rescue").  dd_rescue gives you progress updates and time estimates.  Functionally, it's the same, it just gives more feedback.


                    To copy an image off of an SD card, you'll need to know which device it is and what you'd like to name the image file on your hard drive.  Assume that the SD card is /dev/sdb and you want to name the image file on your hard drive foo.dd.  Run the following command:

                  sudo dd_rescue /dev/sdb foo.dd

                  or if you prefer dd:

                  sudo dd if=/dev/sdb of=foo.dd bs=4k

                    After a wait, you'll have an image of your SD card on your hard drive called foo.dd.  That file is typically very compressable.  Use bzip2 -9 for maximum compression.

                    To write an image onto an SD card, it's very similar.  Again, assume sdb and foo.dd:

                  sudo dd_rescue foo.dd /dev/sdb
                  or
                  sudo dd if=foo.dd of=/dev/sdb bs=4k

                    Note that you shouldn't guess what disk device the card is.  If you guess wrong (ie, /dev/sda), you'll write the image onto your hard drive rather than your SD card.  Errors are dangerous!

                    If you have two SD card readers in your machine (say sdb and sdc), you can copy directly from one card to the other:

                  sudo dd_rescue /dev/sdb /dev/sdc
                  or
                  sudo dd if=/dev/sdb of=/dev/sdc bs=4k

                    This doesn't work for moving data between cards of different sizes.  If you dd a 4gig image onto an 8gig, you won't hurt anything, other than you'll only use half of the space on the 8gig card unless/until you expand the filesystem.  No harm done.  On the other hand, if you try to dd an 8gig image onto a 4gig card, you can cause yourself endless grief.  First of all, there's no guarantee that even if there's less than 4gig of data on the 8gig image that the data is at the "bottom" of the filesystem.  Your system will also see an 8gig partition on a 4gig device, causing all sorts of headaches.  The solution here is to mount the source device (for example, on /media/deadbeef) then partition, format, and mount the destination device ("sudo fdisk /dev/sd?", "sudo mkfs.ext? /dev/sd?", then "sudo mount /dev/sd?? /mnt").  Then you can copy the contents with something like rsync ("sudo rsync -av --delete /media/deadbeef/ /mnt/").  Again, don't just guess the values where the "?" are, you're guaranteed to hork things permanently).  Using rsync will work so long as the data from the larger card will fit in the available space on the smaller card.  If you don't have rsync on your system, you can do it the way we did it in the old days:

                  cd /media/deadbeef/; find . -depth -print | sudo cpio -pdmuv /mnt/

                    But that's pretty old-school. :D  Doing a recursive copy with cp may or may not preserve ownership and permissions, depending on the flags you provide.  And it won't copy special files (ie, files in /dev/, /proc/, etc).

                    that I can use with the Raspberry Pi  computer.
                    I have been unable to  make my own SD cards that will  work.

                      Don't believe you can boot from a dongle,maybe some one else knows for sure. You boot from the SD slot built into the Pi.

                      This place has lots of accessories for the Pi. I have no connection to them other than buying from them a few times.

                        Do not want to boot from a Dongle ,,the Software Defined Radio is in the Dongle  that plugs into the USB port.
                        The SD card   I will boot from  and it  needs to also  contain the Software Defined Radio  software for trhe  Realtec  Doongle   and the Linux operating system.
                        I want some body who knows how to  sell me a preloaded SD memory card  with both the  OS and  SDR software on it .
                        So all I got to do is  plug and play .

                        John:

                        Here's a link to MCM that has 4 gig sd cards with the Raspian Wheezy
                        image on them. http://www.mcmelectronics.com/product/83-14268

                        Don't believe you can boot from a dongle,maybe some one else knows for sure. You boot from the SD slot built into the Pi.

                        This place has lots of accessories for the Pi. I have no connection to them other than buying from them a few times.

                          i have a  SD card with the   Linux OS  needed for  the Pi...but I do not know how to  load the  Software defined radio software onto the SD card 

                          so I can use the SDR   Dongle I bought that has the  Radio receiver circuits in it .

                           



                          John:

                          Here's a link to MCM that has 4 gig sd cards with the Raspian Wheezy
                          image on them. http://www.mcmelectronics.com/product/83-14268

                          Don't believe you can boot from a dongle,maybe some one else knows for sure. You boot from the SD slot built into the Pi.

                          This place has lots of accessories for the Pi. I have no connection to them other than buying from them a few times.

                            John:

                            Here's a link to MCM that has 4 gig sd cards with the Raspian Wheezy
                            image on them. http://www.mcmelectronics.com/product/83-14268

                            Don't believe you can boot from a dongle,maybe some one else knows for sure.
                            You boot from the SD slot built into the Pi.

                            This place has lots of accessories for the Pi. I have no connection to them
                            other than buying from them a few times.

                              I think what John is talking about as a "SDR dongle" is a DVB-T stick that many people are now using as an inexpensive ($15) wide-band SDR receiver that puts out the SDR I and Q signals on the USB connector. They connect the I and Q signals to a PC sound card and use conventional SDR software on the PC to process and display the signals. I doubt that a Pi has sufficient processing power to emulate the capabilities of a sound card and also run the SDR software necessary to complete the processing and run the display and controls. If such a program could be written for the Pi there would be a huge demand for the SD card with Linux and the SDR program all properly configured for use with the dongle.

                                John:

                                Here's a link to MCM that has 4 gig sd cards with the Raspian Wheezy
                                image on them. http://www.mcmelectronics.com/product/83-14268

                                Don't believe you can boot from a dongle,maybe some one else knows for sure.
                                You boot from the SD slot built into the Pi.

                                This place has lots of accessories for the Pi. I have no connection to them
                                other than buying from them a few times.

                                  This is exactly what I am talking about .
                                  Can some one load a SD card with the  OS and Software  I need to do this ?

                                  Then sell it to me ? 
                                   I have tried  but do not understand  Linux  well enough to do it .
                                  I bought a preloaded  SD card with the Linux OS on it but do not  know how to add the SDR software I also need .
                                  I have a USV  3.5 inch floppy drive and I have several  USB memory sticks.
                                  Could the SDR software be  loaded onto  either of them and  then run ?

                                  I think what John is talking about as a "SDR dongle" is a DVB-T stick that many people are now using as an inexpensive ($15) wide-band SDR receiver that puts out the SDR I and Q signals on the USB connector. They connect the I and Q signals to a PC sound card and use conventional SDR software on the PC to process and display the signals. I doubt that a Pi has sufficient processing power to emulate the capabilities of a sound card and also run the SDR software necessary to complete the processing and run the display and controls. If such a program could be written for the Pi there would be a huge demand for the SD card with Linux and the SDR program all properly configured for use with the dongle.

                                    Such programs have been written  to run on the Pi and are available  free on the internet .
                                    QST  January  edition shows how to do it on a PC.

                                    I just do not know how to load them on a  SD card  that I will plug int the Pi.
                                    ...I  see  many  articles describing  how  many others  have already done this ..
                                    .I am not asking anyone to write anything or  create anything that does not 
                                    already exit.   These programs are feee for the Downloading .

                                    I  do not know how to  download it off the internet and install in on the SD card 
                                    with the  Linux OS  that it will run on.
                                    If some one could do this for me  and then sell it to me I wood be glad to pay them for their trouble.

                                    I think what John is talking about as a "SDR dongle" is a DVB-T stick that many people are now using as an inexpensive ($15) wide-band SDR receiver that puts out the SDR I and Q signals on the USB connector. They connect the I and Q signals to a PC sound card and use conventional SDR software on the PC to process and display the signals. I doubt that a Pi has sufficient processing power to emulate the capabilities of a sound card and also run the SDR software necessary to complete the processing and run the display and controls. If such a program could be written for the Pi there would be a huge demand for the SD card with Linux and the SDR program all properly configured for use with the dongle.

                                    Hi John Do you know which SDR program you need to support your SDR device? Which Linux operating system is on your SDcard? (There is at least 5 different ones

                                      Hi John

                                      Do you know which SDR program you need to support your SDR device?

                                      Which Linux operating system is on your SDcard? (There is at least 5
                                      different ones that I know of)

                                      How do you access your Pi, do you have a monitor,mouse,keyboard
                                      attached, or do you use SSH or VNC to access it?

                                      If a version of the SDR software is available for the Pi/linux then this
                                      should not be all that hard to do, we might even be able to do it remotely.

                                        Hi Guys,

                                        Not to toss a wet blanket on what I too would love to see happen, but
                                        the Pi CPU just doesn't have the processing power to run the DSP code
                                        that's needed for a full SDR application. I'm no DSP guru, but this
                                        comes straight from guys who are. Now you might wonder why this is the
                                        case since the Pi is capable of playing beautiful HD quality video?
                                        The answer is, video utilizes the GPU (Graphics Processing Unit) on the
                                        Pi, which is restricted for other uses by terms of the license agreement
                                        to help keep the price low. I'm hoping that this will change someday,
                                        and SDR developers will invest the time and energy needed to utilize the
                                        GPU for SDR purposes.

                                        Meanwhile if you search the archives of this list you'll find my posts
                                        about using the Pi as a "Dongle Server" for a $15 DVB-T stick. I'm
                                        sitting here listening to MIDCARS on 40 meters by running SDR# software
                                        on this XP PC which is getting a stream of I/Q samples from my Raspberry
                                        Pi "dongle server" at the other end of the house.

                                        This application, which only requires the Pi to receive samples from the
                                        dongle and re-transmit them at a rate of 1.024 million samples per
                                        secont via ethernet, takes 30% of the Pi CPU. I control it remotely
                                        via ssh and putty.

                                          Gentle men

                                          I love this idea ...now who can load a SD card with the software I need .
                                          I have a Paspberry Pi and a Hackberry pi with the WiFi built in to the card.

                                          I can hang the Hackberry Pi up in the trees outside ..Solar power it with
                                          rechargeable batteries.
                                          ..right at the antenna and connect threw my WiFi network in my house.
                                          Remotely control it ...
                                          No sound card no video necessary...is every body happy now...can we do this?
                                          who will load a SD card with the Linux OS and the SDR software and server
                                          etc....and sell it to me ?

                                          Hi Guys,

                                          Not to toss a wet blanket on what I too would love to see happen, but the Pi
                                          CPU just doesn't have the processing power to run the DSP code
                                          that's needed for a full SDR application. I'm no DSP guru, but this
                                          comes straight from guys who are. Now you might wonder why this is the
                                          case since the Pi is capable of playing beautiful HD quality video?
                                          The answer is, video utilizes the GPU (Graphics Processing Unit) on the Pi,
                                          which is restricted for other uses by terms of the license agreement to help
                                          keep the price low. I'm hoping that this will change someday, and SDR
                                          developers will invest the time and energy needed to utilize the GPU for SDR
                                          purposes.

                                          Meanwhile if you search the archives of this list you'll find my posts about
                                          using the Pi as a "Dongle Server" for a $15 DVB-T stick. I'm sitting here
                                          listening to MIDCARS on 40 meters by running SDR# software on this XP PC
                                          which is getting a stream of I/Q samples from my Raspberry Pi "dongle
                                          server" at the other end of the house.

                                          This application, which only requires the Pi to receive samples from the
                                          dongle and re-transmit them at a rate of 1.024 million samples per
                                          secont via ethernet, takes 30% of the Pi CPU. I control it remotely
                                          via ssh and putty.

                                            Hi John

                                            Do you know which SDR program you need to support your SDR device?

                                            Which Linux operating system is on your SDcard? (There is at least 5
                                            different ones that I know of)

                                            How do you access your Pi, do you have a monitor,mouse,keyboard attached, or
                                            do you use SSH or VNC to access it?

                                            If a version of the SDR software is available for the Pi/linux then this
                                            should not be all that hard to do, we might even be able to do it remotely.
