Pluto.php. Modified and updated for new DATV channels and other features (IS0GRB)

  • If you are interested, the extensive changes can be read in the file releasenote.txt (see attachment).

    One of the improvements that I am personally enthusiastic about is the option of sending the data directly from the spectrum shown to my Minitiouner (see picture)

  • 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 F5OEO 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.
