  • Two minitiouners on one PC

    Hello Mike,


    there are only one USB on my Minitiouners, but we will see in the future. It would be nice to use one instance of Minitioune for two Minitiouners or for one Minitiouner with two USBs.

  • Two minitiouners on one PC

    Hello Frank DD0CW,


    I have read your message, but I did not answer yet. Sorry for that. I can not find your message now. Thank you for the informations of new software development status. And thank you for your findings.

  • Two minitiouners on one PC

    Hello Jürgen,


    good to know it. I thought, that it is not possible to operate two minitiouners on one computer. But my tests are clear and you confirmed it. It looks that it does not matter what models of minitiouners are used.


    All our minitiouners are with one USB output only - so no possible to use both tuner inputs at one time I think. It would be interesting to try minitiouner with two USBs. I am curious if it would be possible to run minitioune software for each USB output and use both tuner inputs at one time.

  • Two minitiouners on one PC

    It is also possible to operate both Minitiouners with two running Minitioune v1_0_1_1c softwares. I do not know if it is possible with all models of Minitiouners, but it is very interesting.

  • Two minitiouners on one PC

    Hello to all,


    I tested, if it is possible to operate two Minitiouners on one PC. I used Minitiouner-Express and Minitiouner-S. I tested it with Mionitioune Scan & Tioune V0.2k software. When I started this software once, Minitiouner-Express was detected. When I started the same software secondly, the Minitiouner-S was detected.




    I also tried Minitioune Scan & Tioune and Minitioune v1_0_1_1c. When I connected only the Minitiouner-S and started Minitioune v1_0_1_1c, the Minitiouner-S was recognised. After that I connected Minitiouner-Express and started Minitioune Scan & Tioune. The Minitiouner-Express was recognised too.



    Minitiouner-Express was receiving my signal directly on 13cm, because there was not the second output on my LNB.



    So, it is possible to run two Minitiouners on one PC in at least two ways. Perhaps it is a known information, but I did not know it.


    Happy Easter and see you on the sattelite.

  • H.265 Encoder box and Pluto - how to configure?

    Hello Ed,


    try another HDMI cable and if you have another source of hdmi signal try it. When I connect my encoder box to the computer, the audio line in System status shows audio informations, if I disconnect HDMI cable these informations disappear.


    It is possible that audio does not come throught your cable or audio is not present in your hdmi connector - wrong setup of audio output on your computer.


    It is also possible to test your computer HDMI output with TV to check if audio is present.


    If audio is flowing to the encoder, the encoder must show audio information, I think.


    I did not use possibility to save Pluto's parameters to the flash memory, I have to set every time all parameters of Pluto again. When I turn on the encoder before the Pluto, Pluto changes all box parameters - I use my own setup. It is a good idea to change encoder IP address - thank you Mike G0MJW :)



    P.S.:We already spoken that my friend OM0MS had similar problem, it was solved after extending desktop in windows to the encoder. But it is not your problem, because your desktop is already extended.

  • POTY and return loss plot

    Hi Ole,


    I have not the exact values, but I agree with your finding. I am using Zircon L101ECO LNB, there is no need cut original horn - there is open waveguide with lens in original. LNB fits to pipe after small circumferential grinding. I have noticed some degradation of LNB performance with a new extended open waveguide. I have tried use POTY without lens - there is the worst result. With a new 3d printed lens it is by around 3dB better, but not still as LNB in original. Unfortunatelly I have lost original lens, I can not try it.


    For NB is not some small loss so important, most of the signals are very strong, but for WB DATV reception is every dB important, I think.


    I have got another LNB with very long waveguide. There is very interesting lens at the beginning of waveguide. I will try it.

  • POTY and return loss plot

    Measurements of one POTY I have made. SWR is about 1,16 at 2,4GHz. The second picture is the same antenna with some dielectric material inserted between patch and reflector. It gave the interesting result.


    I tried to keep the dimensions in a few tenths of mm. But I still had to bend some parts to tune it :)


    The tube is made of copper, the other parts are of 1mm brass. I didn't have thicker material.




  • Software LNB drift correction

    TNX Harald and Gustavo, nice job and clever solution.


    I am testing script with SDR console 2.3 build 3223. It works perfect. You are a good programmers !! I was thinking about modification of my LNB, now it is not need.


    Many many thanks de Pavel OK1PHU.
