    Thank you for your response SaTom. :70:
    I understand your questions, but it is useless to deal with system noise when the interfering signal is twice as strong as the signal from the satellite. I personally receive satellites from orbit from 53 west to 98 east. The band from 3.4 to 3.7GHz is mainly used by satellites located in the east. In the western positions, they are gradually turning off the transponders in the disturbed band. Reception outside the disturbed band is problem-free.

    Greetings SaTom.
    You are right about something, but if there is a strong transmitter on the relevant frequencies that is close to your receiving device - antenna, then you have a problem with reception. You are probably lucky that the mentioned frequencies are not used in your location. Unfortunately, with us, it is occupied from 3400MHz to 3800MHz. I am attaching tables of assigned frequencies.


    Partial help is in the relevant antenna, but even that is not a 100% solution. The interference is suppressed, but the useful signal is still partially damaged. :25: RE: 5G vs. C-band

    Sorry Lambda,

    but I rotate my antennas with homemade positioners, because commercial positioners (DISEqC) are not able to control such large antennas. That's why I don't use rotation using the IQ monitor. :25:

    Hi Yuri, :70:

    I like your scan speed result. :73:

    I used a step of 1MHz and you used 15MHz and that is a significant difference. That's why you have a shorter scanning time. I prefer thoroughness, especially on satellites that do not have permanently switched on transponders, and then I also use a step of 100kHz. Or HR Spectrum. But that is always an individual case. :68:

    Hello Yuri. :70:
    I rescanned these satellites and saved the images using IQmonitor. For comparison, I also add a scan of 19.2e, which is the strongest in my geolocation. Here you can see the fully rendered window with the transponders. Therefore, I used such a spectrum setting as the basic one. The difference in levels can be clearly seen on weaker satellites, compared to the strongest one. Of course, everything can be set according to your requirements, but I like this one. IQmonitor gives different setting options, so I use them. :91:


    Scan with TBS5925 and same setup with TBS6983.

    It was supposed to be a joke, but it got lost in translation :26.


    I understand now. :26:

    At least you can see the differences in signal levels from individual satellites.

    (Sorry, Google Translate) :68:

    I understand what you are talking about, but why should one tree destroy the whole forest?

    Hi Lambda, :70:

    I don't understand what you mean. Can you write it more clearly? :59:

    Well thank you.

    First, the derivation range is poorly chosen for all spectra. Most of the tablet is unused, and the lower part of it is overloaded with transponder bodies that overlap the signatures of their parameters. Try checking the Auto checkbox

    Hello Yuri, :70:
    I counted on your reservations. Yes, when using "Auto" the spectrum is according to your wishes, but the graphic difference between the levels of transponders on different satellites is lost. I will also list the spectra with TBS6983 here on the forum as you wish. Just a little later, I'm quite busy. :94:

    I greet everyone and especially Yuri. :70:

    I will also add some experience with IQM. For my needs, the IQM version Pro 1030 works best for me. It may have some bugs, but I don't have a problem with it. TBS5925 is used because it has stable parameters and reads the transponder frequency correctly. (I already wrote about it, that the 6983 has a problem with frequency shift) Also. spectrum curves are perfect. Maybe Yurij won't like them, but in my setup you can see the differences in the levels of individual transponders very well - after spectrum calibration. I am attaching a few pictures. I chose the RF range, dB so that the level difference between the most powerful satellite and the weakest was visible.
    Please Yuri, keep developing IQM Pro, it's a very good program.


    Well thank you. :74:


    Hi Yuri.
    I know this is not important, but I found out that there is a problem with the spectrum calibration in the latest version of IQmonitor.

    It renders the horizontal (L) polarity incorrectly after calibration. The spectra shown are after scanning outside the satellite.

    I am also attaching the INI files from the IQ 1028 and 1030.

    Hello Yuri. :70:

    test with TBS5925. In C band 40,5W.
    Accurate RF spectrum works flawlessly, even with all parameters saved.. With dF HR spectrum, rendering is perfect (I like the inset window, gistogramm (C/N)) :79: .

    Also, the rendering of the spectrum is perfect in the part where there is LTE interference from the Internet, 3600-3750MHz.(HR spectrum) :73:

    The problem is only with saving the parameters, as already mentioned. :59:


    Hello Yuri. :70:

    It's incredible what improvements you can make on an IQ monitor. Even if you have very bad working conditions. :48:

    I am already looking forward to the new version of the IQ monitor. :38:

    Please do not forget to fix the error in saving transponder parameters for SmartDVB, ALTdvb and DVBdream. (RE: IQmonitor tool)
    Big thanks. :74:



    Привет Юрий. :70:

    Невероятно, какие улучшения можно сделать на мониторе IQ. Даже если у вас очень плохие условия труда. :48:

    Я уже с нетерпением жду новой версии монитора IQ. :38:

    Не забудьте исправить ошибку сохранения параметров транспондера для SmartDVB, ALTdvb и DVBdream. (RE: IQmonitor tool )
    Большое спасибо.
