IS0GRB Pluto DATV Patch

    Pluto DATV Repeater patch v.1.0 - October 16th, 2020, by Roberto IS0GRB

    This dedicated patch, based on F5OEO firmware v.2908, allows you to create a DATV repeater with Pluto and Octagon SF-8008 decoder.

    It can also be used to retransmit an event in streaming from the Internet, such as a fair, a meeting, etc. locally in a repeater or on QO-100.

    It is necessary to insert the link of the streaming coming from the decoder or from the Internet.

    It also allows you to set an Ethernet Default Gateway when using an USB-Ethernet adapter and to be able to connect the Pluto to the internet, which can be managed from the Internet through a rule on your Internet router.

    I share this project, so that it becomes easier today to make a DATV repeater based on DVB-S / DVB-S2

    Some colleague pointed out to me that after uploading the patch they couldn't remove it anymore.

    He later discovered that instead of renaming the patch to "patch.zip" it was mistakenly renamed to "patch.zip.zip".

    Sometimes with windows and notepad this can happen because when renaming files it applies a default extension.

    To solve the problem access to the Pluto in SSH using Putty (login: root / pass: analog) and issue this command:


    # rm -f /mnt/jffs2/patch*


    then restart the Pluto with this command:


    # reboot


    You can now reload from the pluto.php page my DATV repeater patch, that add some other features, making sure that it is actually renamed patch.zip

    Good morning, this is the v1.1 (October, 24th) of my patch Pluto DATV Repeater


    I reinserted the old fix of G4EML for correct H264/H265 codec seletion in the external box which was present in my first patch of August,15 and lost with the various release changes


    Thanks to Mike G0MJW which pointed out the problem

    I remember that it is important to have installed the firmware version 2908 and not others

    After the appropriate tests, and for this i thank some colleagues who have made themselves available for the tests, IK8XLD, IZ7PDX, IZ5TEP My patch 1.3 for Pluto is ready.

    As mentioned above the patch is compatible with the fw 2908 version.


    In this version 1.3:

    1- Added Pluto TX Frequency Offset and Reset Offset button

    You can now set the TX offset to obtain the exactly TX frequency


    2- Added DATV Beacon Mode

    You can put small .ts video in the Pluto and set properly SR/Mod/FEC. The file must be "beacon.ts"

    You can create the file transmitting with your Pluto with same SR/Mod/FEC and record yourself with Minitiouner and Record button

    A. (Live Beacon):Upload the beacon.ts file, via the form at the bottom of the page, with same Symbol Rate that you intend to use

    File must not exceed 25MB (See Upload Live Beacon file section)

    Now insert this path instead the Default input: /www/beacon.ts

    The file will be played in a loop and will be erased after a reboot or power supply lost.

    So connect before an external 5V power supply/power bank to the right end

    B. (Static Beacon):Upload the beacon.ts file, via the form at the bottom of the page, with same Symbol Rate that you intend to use

    File must not exceed 500kB (See Upload Static Beacon file section)

    Now insert this path instead the Default input: /mnt/jffs2/beacon.ts

    The file will be played in a loop and will be not erased at reboot, so you can use this as portable DATV beacon.

    You can Delete the Live Beacon file or the Static Beacon file using the form at the bottom of the page


    3- Added power slider "Lock to max value". Now you can lock the slider so that also increasing it not exceed the value of the lock


    4- Added Pluto Audio Section. Now you can use low Symbols Rate (SR25,SR35,SR66) changing audio quality directly from Pluto without use external script


    5- Improved Pluto video encoding quality. Pluto's ffmpeg now uses preset "film" which improves video quality especially on low SR


    6- Improved CPU usage. Limited ffmpeg processes that led to exaggerated use of the CPU. With high SR the pluto now behaves better


    7- Corrected some bugs of the DATV Repeater mode



    One of the important and very convenient functions is the possibility to modify the audio quality directly from Pluto, in this way it will be possible to go with low Symbol rate SR66, SR35, SR25 directly in H.264 or H.265 with OBS reducing the audio parameters on the Pluto, without necessarily having to use external ffmpeg scripts that use a lot of CPU and for those who do not have H265 card, from the tests carried out, it has no use other than to reduce the audio for the low SR, but the video quality after all these manipulations it got worse than going straight into H264.
