Thread: RTL-SDR with Enigma2 (SDG Radio)

    Απ: RTL-SDR with Enigma2

    Thanks,@athoik

    I have test this interesting Scan options

    "
    The airband has a lot of channels to scan. Explicitly listing them all is not practical, so use a channel range.

    rtl_fm -M am -f 118M:137M:25k -s 12k -g 50 -l 280 | play -r 12k ..."

    I have use this command line:

    rtl_fm -M am -f %sM:137M:25k -s 12k -g 50 -l 280 | play -r 12k ...


    -f start:stop:interval a range of frequencies to scan and freq step
    It would be fantastic if we have the possibility to change second frequency in the scan option , and may be read frequency that is active.

    I have mod new version Multiband radio with RTL-SDR
    with my very very ,little knowledge of python coding managed to mod/add a few more types of modulation.

    Now we have narrow AM for AIR band, small FM , Wide FM (default all buttons OFF) , and SSB for radio amateurs both Lsb and USB.
    Now we can Tune all freq ,tune in Steps and continu Fast Mhz,Khz, and for SSB step 100 Hz
    To change the modulation only button with the desired modulation
    can be active all the other buttons OFF.(all Off is Wide FM Band)

    @athoik

    Is it possible impl something similar on the SAT box ?

    @athoik

    question for the scan option

    cmd = "sleep 0.5 && rtl_fm -f %sM:146M:25k -s 10k -g 50 -l 280 -M fm

    %sM = start scan freq
    146M = stop scan freq

    Is it possible to make that stop scan frequency can be changed,
    or at least that it is higher for example 1Mhz of selected frequencies ??

    Projects with OpenGL should be capable to display in real time such graphics. On framebuffer should be possible as well, but I guess with a small refresh rate.

    I never tried my self, but should be possible (especially on new boxes with OpenGL).

    Yes, we need to create a settings menu.

    Once the settings menu createad, it can get new entries to handle special tuning cases.

    Or every special mode, can be a new screen, eg screen for AM, screen for FM etc etc.

    I have already keep the requirement for a menu and once there is available time will work on this.

    Please note that we are reading your recomentations and we will implement your ideas when time permits.

    Another great improvement, would be to run rtl_sdr as a service and connect there using a tcp client, if we do that, then changing frequence will not "overload" the stick, becase it would simply send the "change" frequency to service and service will keep running (unlike rtl_sdr command that currently starts and stop).

    So many ideas, so little time!

    I understand because If i make skins I know how much time is needed
    for coding and testing.

    Perhaps there is a possibility of using LCD display on the boxes that have
    If it is not possible on TV screen.

    Too bad we do not have more coders in the SAT world.
    Most are preoccupied with coding images.

    promising results
    Increased operating USB RTL-SDR stability with plugin.

    adde code

    import time

    and

    changed coding/cmd line

    Example:

    def PlayRadio(self, freq):

    self.doConsoleStop()
    time.sleep(0.3)
    self.Console = eConsoleAppContainer()
    #self.Console.dataAvail.append(self.cbDataAvail)
    self.Console.stderrAvail.append(self.cbStderrAvail)
    #self.Console.appClosed.append(self.cbAppClosed)
    if config.sdgradio.rds.am.value :

    cmd = "rtl_fm -f %sM:146M:25k -s 10k -g 50 -l 280 -M fm -A std - | gst-launch-1.0 fdsrc ! audio/x-raw, format=S16LE, channels=1, layout=interleaved, rate=10000 ! audioresample ! audio/x-raw, format=S16LE, channels=1, layout=interleaved, rate=48000 ! dvbaudiosink" % freq
    elif config.sdgradio.rds.fm.value :

    cmd = "rtl_fm -f %sM -M fm -A std -s 10k -g 40 - | gst-launch-1.0 fdsrc ! audio/x-raw, format=S16LE, channels=1, layout=interleaved, rate=10000 ! audioresample ! audio/x-raw, format=S16LE, channels=1, layout=interleaved, rate=48000 ! dvbaudiosink" % freq
