Ciao Chris,

la mia configurazione rx è la seguente:

Parabola offset da 1,8 metri (potete vedere alcune immagini sulla mia pagina QRZ http://www.qrz.com/db/ik8xld

Lnb byllseye tcxo

SDR Airpy mini

Sdrconsole 3.27

La scorsa notte ho provato di nuovo a decodificare il beacon senza successo, dopo aver reinstallato il cavo virtuale e il software wsjt-x.

Un'ultima nota: intorno alle 22z il faro è stato spento.

Hi Chris,

same problem here, despite a strong signal, aboute 13 dB over the noise, I was unable to decode it in Q65-D mode.

Using WSJT-X v 2.4.0.rc4 and SDRConsole 3.27 without filter or agc, in USB or Wide-USB mode.

Hello SWL - markro92,

do you plan to add DVB-T support to your software soon?

At the moment there seems to be no software able to receive narrow band DVB-T under windows, dvb-s_gui seems like a very good candidate.

Hi Syed,

after removing the L7 coil, you can connect the pins in this way and your pluto will come back to life.

You can watch the IS0GRB L7 repair tutorial at this address:

Thanks for this new update Roberto,

I hope your patch and the others can be together integrated by Evariste F5OEO in the next official firmware.

It would be nice to have all available in one firmware.

Great work Roberto,

making a datv repeater has never been easier !!!

I would like to recommend an update of the latest QO-100 band plan, regarding the WB transponder, in the WIDE & NARROW DATV portion.

To avoid wasting precious space, or even disturbing the beacon, the center frequencies for 1.5M 2M channels should be specified.

Those indicated for 1M, 1.5M and 2M are only suitable for 1M channels.

For 1.5M & 2M, only two possible channels should be indicated.

If the frequencies indicated by the band plan are used to transmit at 2M or 1.5M, and in particular for CH No 1, at 10493.25 MHz it is transmitted to the beacon, causing disturbance.

If you transmit at 2M, on CH No 2, at 10494.750 MHz, all three 1M channels are occupied, while only 2 could be occupied by moving to the right of the WIDE & NARROW DATV, leaving a 1M CH 1 free.

If you transmit at 2M on CH 3 at 10496.25 MHz, the NARROW DATV portion is invaded.

Hello Roberto,

just tried your procedure, it works fine.

Now Pluto is connected to the internet with its original USB cable and the pluto.php page is updated via WEB.

thank you once again.

73 Rocco IK8XLD

Thanks again for the new version Roberto.

I use this quick way to upgrade:

A small USB cable connected to the HUB that will keep the pluto powered for the time of reading PLUTO.PHP from the USB pen through an OTG cable, and then connect the USB cable of the pluto to the HUB.

The power can now be smoothly adjusted in 0.1 dB steps.

Very useful feature for those who use large discs and with very powerful PAs.

Thanks Roberto.

have you tried this solution as well?

Hi Lucio,

yes, I tried everything, but nothing seems to be effective. Unfortunately Scan and Tioune does not work with my Minitiouner Express.

Even in my case, the described procedure does not solve the problem.

Tryed also las version of lav filter and Win7DSFilter Tweaker_6.3.

Ciao Jean-Pierre,

non smetteremo mai di ringraziarti per il tuo contributo alla comunità.

Volevo chiederti se sarà possibile utilizzare la scheda PCI TT-1600 con Tiny Spectrum Analyzer.

I have identified the two stages on other similar amplifier with the codes not abraded.

The first one is an SBB2089z

The second one (final) is signed KB863

Tnx George & Michael,

I will work on it

Hi all,

this little PA, no longer has power suddenly, on my DATV setup.

The stabilized voltage is present, therefore the RF amplifiers, one or both, are broken.

The code of the two RF amplifiers have been deleted (see figure) , so as not to recognize the model, but I was wondering if someone was able to do it.

On one of the two, the code has not been definitively deleted and KB or KR is visible

Now a new one has come from china for a few euros and I'm working with that, but I'd like to identify the broken component.

I fully agree with Achim DH2VA, QO-100 is a beautiful gift and we must preserve it . But you cannot relate two episodes that occurred at two different times to the Italian colleague. As DD0KP has already written, we don't blame here with their callsigns, or at least let's do it only if you are absolutely certain. We must try to help to avoid problems. Yesterday I did some good tests with him.

Let´s hope that this was the first and last "alarm" on Es'hail-2 ground station.
Also, I believe that this 2 incidents are related and caused by the same person.
