hat jemand eine Idee, wie man die beiden PA-Ausgänge möglichst verlustarm zusammenschaltet, um damit Hf in eine Antenne einzuspeisen?

Does anyone have an idea how to connect the two PA outputs with as little loss as possible in order to feed RF into an antenna?

USD 400,--

I wonder for what?

Jean DJ0VL hat eine umfangreiche Beschreibung zur Umprogrammierung der LMP92066 erstellt.
Näheres dazu hier: https://groups.io/g/DATVPA/message/832
Diese enthält auch eine Doku über die diversen Pinbelegungen etc.

Als Hardware-Fan habe ich die "Bedrahtungsversion" vorgezogen.

Den von mir bezeichneten Rxx kann man eventuell auch als Poti ausführen.

here is my modification of the gate voltage settings of both PAs

Hi Claudio,
many thanks for the link to this group.

Hi Dominique,

yes, the GT220M in my Notebook is too old. The error message is the same as in #4.

Now I'm using only my PC with the GTX1650 and DATV is running fine with your DATV Easy V2.17
Thank you for this great program.

Here I found some infos how to mod this amp:

This group (DATVPA) offers a lot of infos about mods of 2.4GHZ PAs

Hi Dominique,

In the meantime I had installed the latest Nvidia GTX 1650 driver and my problem on the PC was resolved.
Now I have the same problem on my older notebook with an Nvidia GT220M + Pentium T 4300 + 4GB. Unfortunately there are no newer drivers for Win10. Even if I choose the SOFT encoder, the error message is the same, which I don't understand.

@ Jabi,

the output power can be tuned in 2 to 2 steps with the scroll wheel of the mouse.

Hi Chris,

yes I uninstalled all previous versions and installed only 2.17

Today I have found that 2.17 is running, although this error message appears (see Screenshot)

Hi Dominique,

if I start your new Version 2.17, I get the following error message:

My System: Lenovo-PC with i5-4460, 8GB RAM, W10 Pro 64Bit, NVIDIA GeForce GTX 1650.

Newest libiio + Pluto driver installed.

Do you have an idea what could be the cause?

Hi Tom, fantastic, I never thought that my MiniTiouner would be able to decode two signals at the same time, hi.
Can I decode two different DATV signals on port -A- and on port -B- at the same time, e.g. on port -A- the one on QO-100 and on port -B- my 2.4GHz signal?
I will have more circuit boards made for my MiniTiouner next week. One of them can be sent to you equipped with a housing etc., but without the two FT2232 modules (available from AliExpress) and without the Serit tuner, since Serit can no longer supply them. But hopefully BATC still has some in stock.
I am considering replacing the Serit tuner with a software compatible and available one. What do you think about? Could you adapt your software to this tuner?

Hi Tom,

many thanks for this nice software.

My homemade MiniTiouner V2 is running perfect with the Version 04/01.

I developed the Pluto C/D into a compact TRX together with the LeoBodnar MiniGPSDO and the 20W SG Lab PA. The Pluto is externally clocked at 50MHz. A detailed description with links to curcuit diagrams can be found on qrz.com and on my HP https://www.dj7th.de under "Projects".

Hi Roberto,

it seems that your winlink server is out of service.

Yesterday and today I tried to connect it several times for a short VARA test, but I got only failure messages.

HI Mike,

vielen Dank für den Link. Download hat funktioniert

Hi Mike,

it seems that the above link to your google drive is not working.

Please could you check it and send me an info how I can get the software image?

In letzter Zeit sind Stationen auf 10.489.575 und ...585 aktiv und haben u.a. Bilder gesendet, welche ich mehr oder weniger gut dekodieren konnte. Eigene Testverbindungen mit diversen Stationen haben auch z.T. gute Ergebnisse erzielt.
Leider vermisse ich eine Möglichkeit, fehlende Blöcke von der Gegenstation erneut anzufordern, um nachträglich ein fehlerfeies Bild zu generieren, wie es z.B. bei KG-STV möglich ist.

Hi Rudi,

concrates to the running Pluto!

Remote control of your PC from outside is easy with AnyDesk, but I have no idea how to connect the mike with the remote PC. Maybe someone in this forum can tell us how to do remote operation with the SDRconsole.

So far I haven't found a useful concept for it.

Hi Rudi,

try it with Port:80 and enter the data for Converter and Bandwidth, as in my screenshot

something else:
- did you release the firewall in windows for SDRconsole?

- is the IP of the Pluto the same as the IP in the SDRconsole?
- does your PC have a fixed IP in the range 192.168.0.xxx?

- what happens if you connect the ethernet controller on pluto directly to the pc?
