    Dear all,

    thanking you for the Invacom measurement confirmation sheets sent to me, in return, an evaluation based on the factory measurements of the six types, thirteen copies.
    (For a better evaluation of the column diagrams, a multiplier of 100 was applied to the noise factor values)

    Ranking list:

    Vertical polarization Low band 960 MHz
    1. TWH
    2. QTF
    3. SNH

    Horizontal polarization Low band 960 MHz
    1. TWH
    2. QTF
    3. SNH

    Vertical polarization High band 2140 MHz
    1. TWH
    2. SNH
    3. QTF

    Horizontal polarization High band 2140 MHz
    1. TWH
    2. SNH
    3. QTF

    Conclusion:
    It is well known that there can be no LNB with ideal operation in the entire range of reception ranges, the evaluation can definitely serve as an answer to which types are able to perform above the average value in relation to all types.

    Regards,
    Tom

    Dear all!

    I very wait the Digital Devices brand new DVB component, the Max M2 version.

    Max M2 – DVB Komponenten, SAT>IP Server, DVB-S2, DVB-C2 | DigitalDevices.de – DVB Komponenten, SAT>IP Server, S2, C2

    Maybe March i in the past first readed this card specification, and i think, this card the best alternate, or better choiceof than TBS 6903.

    I have a TBS6903, and I used to have a Cine S2 V6.5 DVB card (which I now know was a mistake to sell), based on my experience, its "sensitivity" exceeded that of the 6903 card.

    This my early version S2 V6.5 component not supported the Crazyscan, and IQmonitor, i used alternate softwer in windows, the LM4 card testing tool. This tool knowig the spectrum analysation, showing the signal in the dBµV, and use DiSEqC, Unicable, CI -CAM modul, and have "ActiveMovie Windows" viewer, i liked.

    Testool (L4M) für TV Karten (Download und Anleitung)

    But now, so pleas share information for who knows when this M2 card will be released in to shop, and at what price, and supported the third party software?

    Regards,
    SaTom

    Luckily for me, yes, i know in this facts, beacuse i work electrical engineer. Of course (or, unfortunately) the microwave communication is not my area of expertise, I know the basics, studies, theses, and anomalies, and I also try to learn more and more even at the age of 50. :-)

    I have many professional LNBs, SMW WDL, SMW DRO, SMW X line, NJR, ComStream, etc, and many professional OMT, adapters, mechanical, and magnetic polar switch.

    I know that your question a "matter of principle", please enabling for i answer .
    Yes, the commercial LNBs ( also the Invacom), not have really validated parameters, maximum under laboratory conditions, or not...this only adveristing.
    If we'll think about it, that the example NEC NE3210 FET validated noise parameter min, 0,35 dB and max. 13,5 dB gain. What can you see on the LNB casing? 0,3 dB. Cant be less the resultanat values. The companys dont calculated in the LNB PCB circuit any loss parametr, bandpass filter, is fact obvious, and knowled. And dont good. But you, and i, and many expert amateur know.

    I am focused commercial sector, priority on Invacom products. I do not examine other products, I do not compare pears with apples. During the measurements and tests, I maintain the same system and elementary chain in the state before and after the conversion (the adapter, waveguide, feedhorn and other, so these are not factors). The goal, as I wrote, is exclusively to test the type of Invacom to be selected, to archive its differences, and if successful, to use it in the tunable waveguide power supply that I have planned. It will be a practical confirmation or refutation of a theory, nothing more i dont searc the zero noise, or any factors... :-)

    (Sorry for my poor English.)

    Dear Amateurs!


    Coming soon here the Sun-Satellites interference time period! This period not good to the DX receptions, but good the satellite dish for inspection, with the sun test.

    My QTH:

    „28E”


    This antenna maybe need in the correction... :-)


    But, this more satellite dish okay...

    „7E”


    and „7W”


    Regards,


    SaTom

    According to them, I guessed right, (or i knowing) :-)

    So far I've processed, reading it up cca. 15 pieces datasheet, I glance at him and i already know, what measuring graphs what is LNB type . (Without i reading the datasheet LNB type section .AND, i maybe now know the "secret", that what type is the "best" consturction. But this study i publishing later... )

    Yes, the right side write, the "standard" marketing kommunications, this not important really, but the type yes.

    Dear Femi!

    Yes, first the data sheet need.

    I readed this Strannik post early years ago, excellent study and test, but the my project another, this is LNB modding.
    (Of course, I know this noise int. interference anomaly theme...)

    So, my the first stepping, categorization of Invacom lnb types according to noise and gain factors. (Using to the datasheet, later of coures with devices...) Second stepping, i to assess, to look at, that the selected Invacom LNB types, how to modificate in the circuti parts, focused to with RF JFET parts. My prject ending goal, changing parts NE3210S01to CE3512K2 HJ PHEMT technology. My plan, that this the modifcated LNB using then to my waveguide project.

    AND, i will use testing the IQmonitor pro :-). (If i buyed the software.)

    Regards,
    SaTom

    Dear DX-r amateurs!

    Please, If you have any type Invacom LNB-s, send to me, or post in the forum the "Actual measured Noise figure and Gain response" titles document, it's easy to read photo, or scanned in format.

    That's what I thought:

    My goal, that i examine, evaluate this LNB typem in NEC NEC3210S01 GF equipped noise and gain indicators.

    Very thanks,
    SaTom

    Dear, all!

    After an apparent skip, a "quick measuring test" at 28.5E Astra 2E H polarization follows.

    (These are not yet the results achieved with the newly designed tube feed and LNB pairs RE: Feedhorn/Waveguide/Scalar Ring , because with that project, the testing and conversion process of additional LNB devices is taking place...)

    So, the presentation of the reception ofthe HL (Horizontal Low) band, two frequencies follows, which can now be classified as among the most difficult receptions in to Central Europe, Hungary due to their polarity, SR and/or FEC values, despite the fact that their system mode remains the long-unchanged DVB-S .

    10714 H 22000 DVB-S 5/6, 10891 H 22000 DVB-S 5/6


    First some screenshots,

    then, measurement result (SR-525HD Diagnostic tool):

    Greetings
    SaTom

    Dear satellite DX amateurs!



    W ill soon be available, tthe privately developed, renamed and improved reporting application with extended functions for the GoldMaster SR-525HD device . :-)


    The new project name of the development (New build name), "SR-525HD Diagnostic", version: beta 4.0


    How its working the new software, what is the new fuctions?


    If started this apllciation, viewed in the first main window the network Connection page.


    "IP"

    In the input box field, it is necessary to enter the IP address of the device, then press the "Connection" button. Based on this, the web API can access and connect to the device. It is important that the web environment and the device operate in the same network and domain.



    (e.g. 192.168.001.100) After pressing the button, if the correct IP is entered, the interface of the main panel will appear, loading the data of the most recently saved "Report" file into the module.


    (RF scan, i.e.) Spectrum analysis graph module



    "SNR/Spectrum_Switch"

    By pressing the switch, the (RF scan, i.e.) Spectrum analysis, and the SNR (i.e. Signal) monitoring graph function can be switched. By default, the option of (RF scan), i.e. Spectrum analysis is available.


    "Satellite list"

    In the case of (RF scan), i.e. Spectrum analysis, the DVB-T, DVB-S/S2/S2X reception source saved in the device can be selected from this drop-down menu for the test.


    "Report list"

    Loading and viewing archive reports that can be selected from the drop-down menu available in the device in the (RF scan), i.e. Spectrum analysis module.


    "Export to JSON"

    Export of completed RF scan, i.e. Spectrum analysis reports, to an external drive.


    "OpenJSON"

    Loading exported archive RF scan, i.e. Spectrum analysis reports into the RF scan, i.e. Spectrum analysis module.


    "Create Report"

    By pressing the function button, a BLIND SCAN-type examination of the reception source selected from the "Satellite list" drop-down list, the Spectrum analysis is started.

    (The parameter settings for the test are automatic, according to the LNB, DISEqC, Tone, Polar modes stored in the hardware, so no separate settings are required.)



    e.g. 19.2 E Astra, or



    28.2E Astra HL


    During the test, the status indicator displayed on the inactive main panel shows the readiness level of the measurement process. (The time content of the measurement process varies depending on the frequency range of the tested receiving source! 10 sec to XY minute.)

    The completed RF scan, i.e. spectrum analysis graph, is displayed on the main panel.



    19.2 E Astra, full spectrum and RSSI (Graph can be enlarged, filtered by selection)



    or 28.2E Astra, HL spectrum 10714 H, and RRSI



    or 28.2E Astra, HL spectrum with 10891 H frequency display, RSSI value.

    In the floating window, that appears moving the cursor on the RF scan, i.e. spectrum analysis graph, and on the X axis, the frequency and parameter data for the receiving source are displayed and can be read.


    "Information"

    On the panel, the values of the parameter settings related to the measurement can be read.

    FPS: Value of application communication data stream

    Status: Status of the connection between the device and the application

    Date: Timestamp of the test

    Satellite position: Position of receiving source

    Satellite name: Name of receiving source

    Converter type: LNB type

    Frequency: Oscillator frequency values

    DSQ 1.0-1.1: Switch port

    Tone: 22 kHz off or on (depends on LNB)


    "Transponder list for SNR report"

    After ending the BLIND SCAN, the (RF scan) i.e i.e. the Spectrum analysis graph completed, and the list of frequencies that appeared on the X axis became available. This drop-down frequency list selector switching to the second SNR monitoring graph module is automatically, and loaded according to the frequency.

    (The second module, the SNR monitoring graph interface, can also be activated with the SNR/Spectrum Switch button, in which case the module will naturally be loaded with empty values.)


    SNR (Signal) monitoring graph module



    28.2E Astra, HL 10714 HL SNR (Signal) monitoring graph, also with LNB and PSU voltage graph display


    28.2E Astra, HL 10891 HL SNR (Signal) monitoring graph, also with LNB and PSU voltage graph display

    If the SNR (Signal) monitoring graph module was not loaded with the "Transponder list for SNR report" solution, the data can also be entered using the input fields.


    "Frequency"

    The value of the frequency to be measured, in units of MHz.

    (e.g. 10714)


    "Symbol rate"

    Symbol speed

    (e.g. 22000)


    "Polarization"

    Select the receive polarization from the drop-down list.

    (Horizontal, Vertical)


    "Tone"

    Selection of audio frequency switching mode of LO low and HI high reception bands from the drop-down list.

    (e.g. KU band 0 – Off L.O 9750, 1 – On L.O 10600)


    "DISEqC command"

    If several LNB units are connected to the system via a switch, it is necessary to select the number of the LNB port to be tested from the drop-down list.

    (e.g. DISEqC port 8, EO1039F7)


    "3D converter polling"

    If the measurement is done with a RAMF 3D LNB unit, select it from the drop-down list according to your permission.

    (0 – disabled, 1 – enabled)


    "Setting the time (min.)"

    Here, it is necessary to specify the measurement time interval, until which we want to perform the measurement, and the drawing the chart. The value can be specified in minutes, which can be from one minute to a time window exceeding the 24-hour measurement. It is important that this setting does not specify the cyclicity of the request, but its duration and time window content! The query is a data stream, so the measured values are continuously displayed on the graphs and are also modified between the variables.


    "Start"

    After pressing the button, the measurement process set according to the "Setting the time (min.)" time window begins. (If there is no specified value, the measurement has an infinite status!) The startted the measuring, the data is continuously updated on the Signal-to-noise ratio and "Voltages" graphs, and is also modified between the variables.


    "Stop"

    Stop any measurement process.


    "Reset"

    Delete all measurement results and data. By definition, this has no effect on already exported data.


    "Export to JSON", "Export to xlsx"

    Export of completed SNR (Signal) reports to an external drive in JSON or xlsx format.


    "OpenJSON"

    Loading exported SNR (Signal) reports into the SNR (Signal) module.


    "Current data"

    The first piece of information, "Processed data", i.e. the counter, specifies the number of responses to the device's queries from measurement cycles.

    The "Alpha", "Beta", "Gamma" values determine the position of the 3D LNB. By definition, in the case of a zero-value 3D converter polling setting, the value is 360 degress.

    LNB current specifies the current consumption value of the LNB.


    Hopefully, an interesting and forward-looking development has been presented in detail.

    I would like the attention of current and/or future GoldMaster owners who are interested in the development to help further work with their testing!


    It is possible to apply by PM, further details will be sent in a reply letter.


    Thank you for your attention, the developer Csnyi and SaTom :-)

    Sorry for the language mistakes.)

    (I moved this my post, maybe the best it here)

    Dear all!

    They would like to buy it four devices, but i dont finding in the market, or it costs too much..

    This is the devices:

    I pay prepaid, in the banking transfer, with shipping costs.
    Not problem if the device dont new, or dont working, or partly working, or litle damaged.
    (I refurbis, fix it, at the end modifie the LNB.)

    I am waiting for the offers in a private message, thank you!

    Have nice day!

    Dear DX amateurs!


    The last one year, significant changes the U.K beams parameter. Several transponder, and/or frequency dramatically difficult to reception became in (also) Hungary, many cases the system mode DVB-S to S2 , FEC 2/3 to 5/6, and the modulation QPSK to 8PSK changed, this increased C/N Lock value.


    However,

    "The new challenges require new solutions", therefore I decided, that design the special waveguide, and for it one modificated LNB converter also. In design important was a point of view, that the biggest efficiency factor, come in the low band frequency range, therefore i planned also three tuning elements.

    (This frequency band wich the most difficult receipting.)


    When I finished the design, sending to my friend zoro67 the drawing, and the produced it the prototype parts. (Thank you Zoro67, nice work!)


    The produce technical drawings, the produce pictures, and the "How it work?"


    The first attachment, one technical drawing, the "IDLP SFLANGE LNB plan cuting_low_res.png" picture. This plan presenting with the Inverto White Tech IDLP S-Flange S/N: P08 series original and modificated plan version. In the plan upper sides two the original, the lower is the modificated LNB showing.


    The second attachment, the "Inverto White Tech IDLP_S_Flange_P08_Original.jpg" picture. This picture presenting to the original Inverto White Tech LNB. It can be seen that here the flange and the waveguide are also part of the LNB.


    The third, and the fourth attachements, the "Mod_Inverto_White.jpg, Mod_Inverto_White_II.jpg". This pictures showing the modificated LNB cover, with the new screw probe console. (Technically, removed the LNB flange and waveguide elements, then produced, and aplied the new screw probe console. This solution allows you to, that the probe the size of the part of extending into the waveguide can be adjustable, which can thus be changed according to the wavelength of the frequency (more precisely well as the λg). This is the first tuning option, λ/4 to λ/2.)


    Fifth, and sixth attachment, the "Mod_Inverto_PCB.jpg, Mod_Inverto_PCB_new probe.jpg" pictures, this showing the modificated LNB PCB boards. (Technically, I removed the Vertical and Horizontal probe, then I had a 14K gold probe with a suitable cross-section and length manufactured, which put in to the Vertical probe place.)


    Seventh attachment, the one picture the definitively modificated LNB "Mod_Inverto_White_with_probe.jpg". (The probe is longer than the console. The protruding probe part, extends into the waveguide when assembled.)


    Eighth attachment, one technical drawing, the "Waveguide for IDLP_low_res.png". This picture showing the specially waveguide. (The circular waveguide inside diameter (λg), calculated for the low KU frequency band. )These drawing have it more also elements, with the adjustable back short circuit plate, and the reactive screw adjustment, for the best tuning. (This is options, the second and third tuning options. The three tuning element, together, it makes it possible to achieve the best RF power, SWR and reactance factors, ergo the best available reception performance.)


    The ninth attachment, the "Specially_waveguide.jpg" picture. This is picture presenting the definitively produced waveguide device. (In the the Backshort plate outside, a little milling is visible, this can be adjusted with a screwdriver. This is the option, for the backside reflection adjustment. And with the screw, can be adjusted the inductive or captive reactance.)


    I hope you liked the presntation, I welcome questions, corrections, and/or the comments.


    Of course, the project it didn't end, we still have a lot of tests and technical clarifications ahead of us. As soon as the successful tests performed in the home environment are completed, I presenting also the reception reports. :-)

    Best regards,

    SaTom

    Dear amateurs,

    in the absence of time and in the shadow of the new wavegiude project, a short "outlook" should follow, which is intended to show what results can be achieved in the field of the upcoming summer and typically evening peak periods (In Hungary):

    11305 H, tp 109, UK, DVB-S, 27500, 2/3 (11306 H) 5.6 dB

    11306 V, tp 110, UK, DVB-S, 27500, 5/6 (11307 V), 7.1 dB

    11344 V, tp 112, UK, DVB-S, 27500, 5/6 7.3 dB

    12382 H, tp 35, UK, DVB-S, 27500, 5/6 7.5 dB

    Best regards,

    SaTom
