    Thanks for this new update Roberto,

    I hope your patch and the others can be together integrated by Evariste F5OEO in the next official firmware.

    It would be nice to have all available in one firmware.

    I would like to recommend an update of the latest QO-100 band plan, regarding the WB transponder, in the WIDE & NARROW DATV portion.

    To avoid wasting precious space, or even disturbing the beacon, the center frequencies for 1.5M 2M channels should be specified.

    Those indicated for 1M, 1.5M and 2M are only suitable for 1M channels.

    For 1.5M & 2M, only two possible channels should be indicated.

    If the frequencies indicated by the band plan are used to transmit at 2M or 1.5M, and in particular for CH No 1, at 10493.25 MHz it is transmitted to the beacon, causing disturbance.

    If you transmit at 2M, on CH No 2, at 10494.750 MHz, all three 1M channels are occupied, while only 2 could be occupied by moving to the right of the WIDE & NARROW DATV, leaving a 1M CH 1 free.

    If you transmit at 2M on CH 3 at 10496.25 MHz, the NARROW DATV portion is invaded.

    Hi all,

    this little PA, no longer has power suddenly, on my DATV setup.

    The stabilized voltage is present, therefore the RF amplifiers, one or both, are broken.

    The code of the two RF amplifiers have been deleted (see figure) , so as not to recognize the model, but I was wondering if someone was able to do it.

    On one of the two, the code has not been definitively deleted and KB or KR is visible

    Now a new one has come from china for a few euros and I'm working with that, but I'd like to identify the broken component.

    I fully agree with Achim DH2VA, QO-100 is a beautiful gift and we must preserve it . But you cannot relate two episodes that occurred at two different times to the Italian colleague. As DD0KP has already written, we don't blame here with their callsigns, or at least let's do it only if you are absolutely certain. We must try to help to avoid problems. Yesterday I did some good tests with him.

    Let´s hope that this was the first and last "alarm" on Es'hail-2 ground station.
    Also, I believe that this 2 incidents are related and caused by the same person.

    Hi all,

    here my new QO-100 portable set-up.

    Great result using 2W transverter on 40cm dish with home made dual feed.

    with too many adapters, but I didn't have the right cable at the moment.

    Fantastic satellite.

    Hi Heiner,

    I follow your advice willingly, hoping that Jean-Pierre F6ZDP will listen to us.

    I also have a TT-1600 that I now use with EBSPRO.

    Having TUTIOUNE able to decode DVBS-2 would be useful for low SR.

    In this regard, up until now I was able to receive only 1MSR transmissions using EBSPRO

    No DATV <1MSR transmission is detected by blind scanners.

    Only 1MSR are detected by the blind scanner.

    Maybe you manually tune the transponder after seeing the parameters on the websdr (333SR 500SR)?

    For completeness, I report the version of the drivers used:

    Driver BDA

    Streamreader.dll original software EBSPRO

    I've already edited the streamreader.ini file to get the 700 MHz IF

    Thanks for the reply.

    Now the range is free and can reach up to 10.492

    I also wrote to Jean for TT-1600 and DVB S2, I hope he will satisfy us.

    With EBSPro I can not reach the frequency of 10.492.

    There is a limit to 10.7000.

    I tried to edit the streamreader.ini configuration file without success.

    I see that DG0OPK has been successful in this.
