Tip: (with the help of martin...:))

goto putty into the raspberry

git clone https://github.com/dj0abr/QO-1…bSDR_DATV-WebSpectrum.git

cd QO-100_SSB-WebSDR_DATV-WebSpectrum

./prepare_ubuntu_pluto

./build_RTLSDR

sudo ./qo100websdr

And than it should work...

one question. I need to connect my pluto via USB to the ryde.

If so, i cannot use the pluto for TX any more..

Why not use the pluto via network..

I succesfully used 1 pluto for DATV-TX and sdrconsole for RX via the network...

So if the WB would use the pluto via network i may be able to use the TX. but we probably would get problems with 8 Mhz wide view..

Looking forward to the next update...

Thanks ..

Benno

Well there you have it..

after you wget or gitclone...

I need more help with that..

i know how to download it onto widows but the right command to get it directly to the ryde rasp... is a dark mistery..

There is no easy wget installllll.sh......

Hi martin,

I get

Not Found

The requested URL was not found on this server.

Apache/2.4.38 (Raspbian) Server at 192.168.1.28 Port 80

But thats not a supprice as i cannot start the server to config it at all...

-bash: ./prepare_ubuntu_pluto: does not exsist...

If i look in the script i can run the induvidual commands ..

It seems i need a wget to get its out of the github into my running ryde..

But there is the lacking knolledge..

Benno

I am a bit lost...

Have ryde over one year and found this addition..

I know my ways to my raspb... but have no qlue how i should install this..

I have entered the command lines in the mentions file into my putty and although its doing a lot there is no webserver yet..

I copied the github data into my rasp. but cannot start the scripts there...

So little help for the starters would be appriciated..

hi Roberto..

Thanks for your fast reply.

I use the pluto not via lan adapter but via USB..

I've 2 pluto's boxxed in together with USB splitter and sufficient power.

So i really do not want to go to Lan option as of now.

As many other use USB connected pluto's i'd really like to find the solution of getting it working via the PC router option..

Like to have more pointers if you have any.

Thanks in advance...

Will play on and reporting results in the other thred.

Thanks for now2...

Hi Super smart..

works fine for me

BUT..

i can now ping 8.8.8.8 but NOT my connected pc nor my home router...

Can you explain or tell me how to get a ping to my PC?

reason is to get new 2110 firmware controlling the minitiouner

whitch is not yet posible when your pluto is connected via USB e.g not on the same lan..

Benno

Hi Adrian...

If we only understand....

I am also struggeling but found in the help..."The Pluto must be connected on the same local network,"

if you, like me, connected the pluto to USB port the pluto works in different network e.g. 192.168.2.x.

I have not find the workaround...

check so far the netmask in the pluto and corrected to 255.255.0.0

but its not in the pocket yet..

Need to be smarter...

Hello Christian,

Finally today installed the new 21-10 version..

found your great and long awaited improvements but its not working..

I have minitiouner express running on same windows 10 PC.

QO-100 WB live tune works fine..

have the port en 232.0.0.11 default working..

Did setup the 2110 witch is straight forward..

see the message "receive channel change request completed"..

But nothing happens in minitioune V0.0_9.1h

what am i doing wrong?

Best regards

benno

Datv Signal Processing creates a delay Up to 15 Seconds. If you add delay for handover normal qso gets difficult and inpracical. Using 2nd datv audio channel Will add extra delay for Signal Processing..

Gentleman.. the Amsat Organisation is clear.. they Will Not allow Any FM in qo100

This was the basic question. All Others solutions are Working, has been used OR Not the andere..

I am able to send 2 seperat Signals an able to receive 2 seperat Signals..

NB USB is currently the only Working solution and the rest is not practical...

Thanks for your thoughts..

Did some testing on both ideas...

Recently i am able to be QRV on NB and WB in same disc and amplifier..

Doing NB USB is a good option but indeed far from perfect. zerobeat signals and squelch problems makes it less preferable for the DATV station.

NFM or even WFM will fit easy between WB channels and is better in respect of quality and easy to use.. You can better work with squelch options and even CTCSS.. Downside, youll need over 10Watt FM to get a desent S9 R5 signal...

In stead of the 4 watt needed for a similar USB signal...

You can even put the NFM channel inside the DATV signal but youll get lots of white noise in the reception and the D quality of the DATV signal goes down rapidly...

So that not wat one should want...

Normal 2 way QSO on DATV is still not so easy as there is a big delay in coding and decoding causing up to 15 sec waitings in microfoon hand overs....

So what would be the reason not to use NFM in the WB section of this nice project other than it needs to be allowed??

@markro92 Great Software, But it seems DVBS1 is not working anymore..

Tested on 3 different locations with different computers and setup's

Tested on 144.600, 436 Mhz and 1255mhz.

Use RTL stick as receiver.

DVBS2 works simple and perfect.

250 KS up to 2Ms..

But switching to DVBS1 i get the constalation perfect but no sync..

not even more than 1.

I use 500KS FEC 2/3 DVBS1 H264... for testing...

Can you confirm that DVBS1 should work?

Best regards...

What would be the max DC input for the UMTS siemens/nokia amplifier.

Currently running on 28V and i know 32 Volt is mentioned but the max ratings of the LDmos are much higher.

I have a 400 watt 35Volt DC supply and i just wonder if the gain and more important the efficiency would benefit from a higher DC input.

Or will i just smoke some parts...

Colleagues looking for an inexpensive 23cm amplifier, I started modifying it and something goes wrong.

Not sure why you are asking for 23 cm but the eshail is using 13 cm uplink...

I can confirm...

I have now 2x these UMTS working..

First one i damaged the coupler..

But with the second i prepared the the output with additional SMA..

And i use to measure my output for reference..

Be aware, the output can really change if output is not 50Ohms..

I have seen more than 50% difference in output due to bad connectors witch off cause don't show on the referenced output.

Hi..

Its the famous leo bodar GPSDO witch is available but way to expensive for my tast..

Hi..

We got a few of these LPT04H lnb and the y show something strange.

When connected to 1 port it all seems good, bit high in the noise but very reasanoble..

But when i connect the 2nd port i and give power on that port the first port looses 3dB or more..

The freqency of the first port also changes..

There is no different witch port i start with but when connecting the second port to either NB (pluto) or WB (Minitiouner) the signals go bad on both ports.

The bias voltage is from the same source and just lowerd with some resistors and diodes...

Anny idea's...

Hi, I have same problem with 25Mhz generated by Si 5351 by GPSDO. Is there already a solution to the problem? I'll be glad if you can share it.

Best regards

Well, NO..

I left completely the path of GPSDO and am using a 25Mhz TCXO with an extra 5 stage 25MHz Xtall-filter.

This gives me pretty stable results finalizing with the beacon lock.

Still have the GPSDO with DDS and SI5351 but not using them..

(in) decent behavior.

This letter is most likely not for YOU as we are respect full hams and follow the QO-100 rules to the letter. But then, if the world a perfect place this letter would not be written.

A group of hams did something great and created a wonderful medium we now call QO-100.

A nice new feature to our hobby witch already gave lots of old hams a wakeup call, and provided a lot of nice QSO’s.

But old habits seem to overshadow the novity of the Es-Hail and shortwave rules where the strongest gets the most seems to be more and more the case on QO-100.

And if someone disagree, he just starts to disturb others with sirens and text remarks or other wide band signals. The more power the better!!!!

We call them pirates but are they really or is this just how humanity works these days.

It seems RESPECT is lost when a special call is on air. We do not wait our turn but just turn up the power a bit…

When we hear a special Call in QSO, we do not wait till he actually calls for CQ but just start screaming our call…

We do not check if frequencies are free when we want to test our amp or antenna

When we tune to a frequency, we use full power.

I really understand if someone is testing and got not everything perfect but we have the great possibility to check our signals via the webSDR websites all over the world.

I really understand if someone is testing a new communication mode as this it all what our wonderful hobby is about. But we all know the QO-100 bandplan and where we conduct these tests.

Please I strongly ask you, Have RESPECT.

Lots of novity Calls get completely scared to just call CQ. Lots of them are like us in the beginning, just happy it works. Most of them are technicians and not experienced contest boomers, not used to do some pileup management. They will answer a CQ call and the quickly change the frequency.
