IS0GRB Pluto DATV Patch

Pluto DATV IS0GRB Patch v.1.9 available

1- Added compatibility for using SDRConsole with all F5OEO firmware.

With the latest basic versions of the F5OEO firmware, the SDRConsole functionality is enabled or disabled by a specific setting in the SETUP page.

You are therefore obliged to open the Pluto page and set this mode in order to use the program.

Being bound by this selection, the SDRConsole program does not transmit because PTT is not enabled by default.

As has been verified on SDRConsole, when the TX key is pressed it does not actually send a PTT command but only the setting of the power level selected with the slider in the TX part, as it is based on the official firmware version of the Analog device where the PTT is always enabled.

As soon as the "pluto.php" web page is opened, PTT is immediately disabled.

From then on you can select your PTT ON / OFF preference after applying the settings by pressing the "Apply Settings" button.

If you decide to use SDRConsole again, you can do it in several ways:

A. Manually enable PTT from the Pluto web page if it is still open on the browser

B. Reboot the Pluto

C. Disconnect / reconnect the Pluto from the USB socket if connected in this mode

2- Fixed a bug on the memorization of the flags on the 4 types of modulators Normal OBS, Repeater, Live Beacon, Static Beacon

When creating the memories, the 4 flags were not stored and then clicking on Apply Settings, sometimes, in the repeater or beacon mode the Pluto did not transmit, because an addressing path not compatible with the chosen DATV mode.

3- Added the SR20 in the modulator drop-down menu.

4- The PCR and PAT sliders now start from 40ms, to set the correct PCR value as required by the DVB protocol specification (100ms).

Suggested values for perfect synchronization even in Graph mode of the minitioune PCR 100ms and PAT 100ms.

If the minitioune has problems with synchronization in Graph mode, press RESET on the side to synchronize the transmission correctly.

It is important to correctly set the keyframe value in OBS. Set the value 2sec if you use Steaming or the value (fps x 2) if you use Recording.

5- Added audio bit rate values from 32k up to 48k to the Audio Settings drop-down menu.

6- Added the possibility to set the buffer latency in the encoding, from 100ms to 1000ms (Default 400ms).

This parameter has been added on memories.

7- DVB Provider removed from memories.

The string saved with "Save to Flash" is used.

8- Added link at the top of the help page for setting the metric on the pluto network in case of problems during tuning by clicking on the spectrum signals.

Pluto DATV IS0GRB Patch v.2.0 available

1.Normal DATV mode with OBS:

-Inserted new colors for the memories (Yellow, Brown, Harlequin Green, Light Turquoise)

-Added Yellow (default) and Turquoise colors for the BATC spectrum

-Compacted controller page and reformatted to have all commands aligned when the browser window is minimized, so as to keep under control even minitioune if you use only one monitor

-Inserted PTT ON-AIR timer counter; after 10 minutes of continuous transmission a beep will be emitted for 5 seconds, non-invasive, to alert the operator

-Added 8000Hz and 32000Hz audio sample rates in the audio coding section

-Added automatic 3rd harmonic frequency calculation for frequencies from 6GHz to 18GHz:

[The pluto as you know is capable of generating different harmonics.

After numerous tests carried out and after some comparisons with the author of the Satsagen software, we found that the Pluto in the harmonic frequencies does not modify the modulation as the mixers work in a harmonic way,

the base band then modulates the carrier in the mixers on the harmonics and for this reason the modulation on the harmonics is the same as the fundamental.

This observation opens a new world of experimentation in DATV even on frequencies higher than 6GHz, for example it is possible to transmit in DATV even in 10GHz by setting the 3rd harmonic frequency.

It is sufficient to filter the 3rd harmonic with a dedicated filter for 10GHz, amplify it and you are operating at 10GHz in DATV. The third harmonic has a level of about -35dBm.

It is also possible to carry out tests without a filter; set 3457MHz on Pluto and with an LNB nearby you can perfectly see each other again at 10371 MHz.

This therefore also allows the Pluto to be used as part of a "Low cost" 10GHz transverter.

I thank my colleagues Raffaele IW1QEF, Roberto IK6BLO and Giulio IK2DED for the tests and measurements.]

2.RF Repeater DATV Mode:

-Added internal functionality of Transport Stream source switch in order to use an IP-Camera for the beacon in repeater mode.

(When the repeater is active and no signal is in transit, the beacon will be sent with the streaming of an external IP camera. Tested on our IR0UDV repeater in Cagliari with a Full-HD IP-Camera)

-Possibility of selecting 4 beacon sources in repeater mode (IP-Camera with external script, IP-Camera with HTTP streaming, Live beacon video file or Static Beacon video file)

3.Beacon mode

-Added beacon mode timer and timer duration. Up to 6 timers can be configured; each timer can have a maximum duration of 10 minutes

-Clicking on "Save" in the "Beacon Timer" section will also configure the correct time to the Pluto; useful if connected via USB.

There is also a special button to do just this operation; if the Pluto is connected via LAN, the time will be updated via the Internet via NTP server.

4.Documentation:

-Inserted link at the top of the page for OBS Studio configuration guide in H.265 without a dedicated card

-Included guide for IP-Camera configuration in beacon mode

5. Fixed some bugs in Normal and Repeater mode

Hi, i confirm that if you have already installed the Evariste firmware you can upload the patch via the Maintenance > firmware section. Select the patch.zip file you previously saved. Make sure the file is not renamed by windows

Hello Roberto, thanks for your interest.
The patch can be used with any version of Evariste firmware; i did several tests and the colleagues who followed the tests with me did not report any anomalies with specific firmware versions.
Personally i always use the 2908 for power reasons, which in my setup is necessary, otherwise i would have to modify the PA chain, but for the SR 35, 25 and 20k, the 0201 and later, as you well know, is definitely, better for the quality of the signal transmitted at 16APSK and 32APSK, on the other hand the power delivered is slightly lower and requires greater amplification.

Hi Rolf sorry I'm late.
You should verify that all fields of the web page form are validated.
If you have never installed the my patch for DATV it is likely that some fields have no value as they are taken from the configuration saved in the Pluto.
Essentially check the Audio settings part, set to Default and Encoding, set to Internal.
To be sure, check that the symbol rate is set correctly. if you still have problems send me an email
