  • QO-100 Linux Transceiver on PI four

    The install scripts check the /etc/os-release file to decide what the OS is. However, on my system which is the latest 64 bit OS the file contains:


    PRETTY_NAME="Debian GNU/Linux 11 (bullseye)"

    NAME="Debian GNU/Linux"

    VERSION_ID="11"

    VERSION="11 (bullseye)"

    VERSION_CODENAME=bullseye

    ID=debian

    HOME_URL="https://www.debian.org/"

    SUPPORT_URL="https://www.debian.org/support"

    BUG_REPORT_URL="https://bugs.debian.org/"


    uname -a: Linux PI4 6.1.21-v8+ #1642 SMP PREEMPT Mon Apr 3 17:24:16 BST 2023 aarch64 GNU/


    and as a result the scripts do not correctly detect the OS as being Raspbian 64bit

    Thanks for the reply.


    I had seen the comment "the install script was made for debian/ubuntu based Linux systems" but assumed that the OS I am using (Debian Bullsey) would be OK.


    How do I find out what OS DJ0ABR initially used?

    I am trying to install the QO-100 Linux Transceiver on my PI four using

    Code
    wget https://raw.githubusercontent.com/dj0abr/QO100_Transceiver/main/install
chmod 755 install
./install

    but the install fails with the message:

    <<<

    Some packages could not be installed. This may mean that you have

    requested an impossible situation or if you are using the unstable

    distribution that some required packages have not yet been created

    or been moved out of Incoming.

    The following information may help to resolve the situation:


    The following packages have unmet dependencies:

    libpulse-ocaml : Conflicts: libpulse-ocaml:armhf but 0.1.3-1+b1 is to be installed

    libpulse-ocaml:armhf : Depends: ocaml-base-nox-4.11.1:armhf

    Conflicts: libpulse-ocaml but 0.1.3-1+b1 is to be installed

    libpulse-ocaml-dev : Conflicts: libpulse-ocaml-dev:armhf but 0.1.3-1+b1 is to be installed

    libpulse-ocaml-dev:armhf : Depends: ocaml-nox-4.11.1:armhf

    Depends: ocaml-findlib:armhf but it is not installable

    Conflicts: libpulse-ocaml-dev but 0.1.3-1+b1 is to be installed

    E: Unable to correct problems, you have held broken packages.

    >>>


    The OS on the PI is a very recent 64bit and apt-get update and upgrade have been done. The only other software that has been installed is Domoticz.


    Any pointers anyone? Is this because the OS is 64bit perhaps?


    Thanks

  • Pluto calibration

    I have just bought an Adalm-Pluto (rev B) for use on QO-100 but I don't have a pre-drive amp yet (it has been ordered from Sandor DM4DS). It will drive an SG-Labs PA V2 and replace my 70cms transverter solution.


    I want to see how good/bad the frequency calibration and drift is. So my question is how to do this? When I am able to transmit to QO-100 I can use the beacons but I don't have a frequency stabilised LNB or access to a signal generator either.


    Any ideas?
