We are talking here about a hobby, not a commercial available and maintained Software....

Stay cool and make your donation to support and allow further developments.....don´t be rude and force updates.....

We all have limited spare time and sometimes maybe more important things to do....

I´ve given my pluto a fixed IP by entering the IP of the network adaptor here:

[USB_ETHERNET]

ipaddr_eth = 192.168.1.205 (example)

netmask_eth = 255.255.255.0

Do not forget also to enter the IP of the standard gateway of the host.

DHCP can lead to changing IP adresses.....

Maybe flashing the Pluto via USB again could solve the problem....

Latest DATV version can be found here:

Hi Trevor,

you have modified the config.txt with the right IP adress of the ethernet adaptor?

http://www.dd1us.de/Downloads/…20Area%20Network%20v2.pdf

If you power the ethernet adaptor directly via your PC and connect it to the network, did you see the adaptor in your network? Are you able to ping it?

Those IP adress have to be used in the config.txt.

So even a PING is impossible?

You know the IP adress of the network adapter? Can you ping it?

Hi,

I could solve my problems by adding an additional capacitor at the power feeding point, just 1000yF and 100nF.

The output of the PSU was not clean enough.

I am powering via the Ethernet adaptor only.

Hi,

I observed the same problem today, but my Pluto has the GND modification and I am powering with a 5.2 V / 3A power supply.

So most common reasons should have been avoided.

Just be patient..there is already a proof of concept. Now packaging it in a new firmware for plutosdr.

You need :

- PLutoSDR

- HDMI input : https://www.ebay.fr/itm/WR-USB…Audio-Record/184364880346

- If you want analog in , add Analog to HDMI : https://www.ebay.fr/itm/AV-to-…ter-HDTV-DVD/274349165620

- Future DATV plutosdr firmware

That's it : all in one encoder - DVBS/S2 modulator less than 200 Euros.

More details soon.

Hi,

out of curiosity:

You link HDMI input : https://www.ebay.fr/itm/WR-USB…Audio-Record/184364880346 points to a converter USB IN to HDMI out.....

How to get HDMI in a Pluto? Or is the picture wrong?

DG8KD There should be signal strengh. Your proposal is not a solution, because if the signal strengh is available the PID will be done automatically.

I see a RF power of -51 dBm in http://www.vivadatv.org/download/file.php?id=1863

This should be sufficient.

5th button on right hand side named "France24"

may be need to enter frequency and SR manually

Yes, wrong PIDscan lead to the unability to decode the TS, even to the impossibilty to lock the TS...

PS: will the short destroy both Serrit inputs A and B?

Hi,

I am not talking about a full misallignment , may be a lttle bit....

If you are able to receive the normal TV programs the MT itself is in working condition.

The picture http://www.vivadatv.org/download/file.php?id=1863 shows the wrong pids.....

Hi Enzo,

Are you able to receive BBC arabic on BADR4 with the MT pro? Same position as QO-100

or France 24 which has a Bookmark in MT:

Hi Lutz,

I was struggling with the same problem.

With the following approach I was able to access the Pluto via my LAN:

Hope that helps.

Congrats David !

And for the absolute fine tuning now use your SDR and tune for the maximum of the beacon on the Ham transponder.

Hi David,

But what has this to do with the EPG data? I did not get it...

For the first alignment BBC Arabic is a good starting point, not on Es´hail-2 but close enough on Badr4.

For fine tuning later on the beacon can be used.

Cheers

Rainer

Normally a KU-Band LNB for a prime focus antenna looks this way:

The groove feed is used to bundle the received signals from the antenna again and "forward" them directly to the LNB. Without the groove feed, reception in the C-band is hardly possible. While the groove feed is suitable for Prime Focus antennas, a funnel groove feed should be used for an offset antenna. Not only do these look similar to a funnel, but they also behave in the same way on offset antennas.

Everything which is blocked can not be transmitted.

So if you put it after the PA it will eliminate all rf (ok, mostly) outside the bandpass.

If you put it before the PA all mixing products which can occur in the amplifier will go to the antenna.

So I would recommend the installation after the PA.

Hope that makes sense.

2 watts? What giant dish are you using

Kurt

According to this link https://wiki.batc.org.uk/QO100_DATV_Users, Mike uses a 2,4 m dish and 32 watts...

Transistor Bias Voltage (PTT) Switching options Selectable by Jumper:

1. PTT is switched ON by connecting PTT pin to the ground.

2. PTT is switched ON by applying +3....+12V to PTT pin

3. PTT is switched ON simultaneously with Power Supply Voltage.

Directional Coupler Voltages:

1. FWD Voltage Input 0.5V typ. @ 0.5W input power

2. FWD Voltage Output 3.5V typ. @ 20W Output power

3. REF Voltage Output - reflected wave , can be used to calculate estimated output SWR

Hi,

according to Noel, G8GTZ, 5 sets of the BATC minitiouner will become available next monday, Dec 4th
