Even if the frequency is lower than the minimum frequency indicated on the LNB manufacturers&#8217; data sheets, the latter will be perfectly suitable. So no need to generate 22kHz, and its power supply will be below 15V to activate vertical polarization. The station power supply you probably already own and which usually supplies 13.8V is therefore perfectly suited to power the head via the T-Bias.<\/p>\n<h4>Get the LNB PLL heads<\/h4>\n<p>As mentioned above, it is important to choose a PLL LNB.

Now all you have to do is adjust the elevation, searching directly on your SDR receiver for the strongest signal levels<\/p>\n<p>The third adjustment consists in rotating the LNB unit on itself according to the value of the skew angle.<\/p>\n<p><img decoding=\"async\" src=\"https:\/\/www.toutimages.com\/google_satellite\/images\/polarisation2.gif\" \/><\/p>\n<h3>Online software to help with pointing<\/h3>\n<p>After indicating your location, and the desired satellite, these websites provide information on the azimuth, elevation and skew angle to be adopted to point the satellite.<\/p>\n<ul>\n<li><a href=\"https:\/\/www.dishpointer.com\/\" target=\"_blank\" rel=\"noopener noreferrer\">www.dishpointer.com<\/a><\/li>\n<\/ul>\n<p id=\"Jbilmrd\"><a href=\"https:\/\/www.f5uii.net\/wp-content\/uploads\/2019\/04\/img_5cb77a4cc3975.png\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-2628 size-medium\" src=\"https:\/\/www.f5uii.net\/wp-content\/uploads\/2019\/04\/img_5cb77a4cc3975-300x240.png\" alt=\"\" width=\"300\" height=\"240\" srcset=\"https:\/\/www.f5uii.net\/wp-content\/uploads\/2019\/04\/img_5cb77a4cc3975-300x240.png 300w, https:\/\/www.f5uii.net\/wp-content\/uploads\/2019\/04\/img_5cb77a4cc3975-768x615.png 768w, https:\/\/www.f5uii.net\/wp-content\/uploads\/2019\/04\/img_5cb77a4cc3975-187x150.png 187w, https:\/\/www.f5uii.net\/wp-content\/uploads\/2019\/04\/img_5cb77a4cc3975.png 1207w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><\/a><\/p>\n<ul>\n<li><a href=\"https:\/\/satlex.de\/en\/azel_calc-params.html?satlo=&amp;user_satlo=25.9&amp;user_satlo_dir=E\" target=\"_blank\" rel=\"noopener noreferrer\">www.satlex.de<\/a><\/li>\n<\/ul>\n<p id=\"rbbTOEL\"><a href=\"https:\/\/www.f5uii.net\/wp-content\/uploads\/2019\/04\/img_5cbdad73986ef.png\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-2667\" src=\"https:\/\/www.f5uii.net\/wp-content\/uploads\/2019\/04\/img_5cbdad73986ef.png\" alt=\"\" width=\"286\" height=\"302\" srcset=\"https:\/\/www.f5uii.net\/wp-content\/uploads\/2019\/04\/img_5cbdad73986ef.png 623w, https:\/\/www.f5uii.net\/wp-content\/uploads\/2019\/04\/img_5cbdad73986ef-284x300.png 284w, https:\/\/www.f5uii.net\/wp-content\/uploads\/2019\/04\/img_5cbdad73986ef-142x150.png 142w\" sizes=\"auto, (max-width: 286px) 100vw, 286px\" \/><\/a><\/p>\n<h3>Software for mobile phones<\/h3>\n<p><a href=\"https:\/\/www.f5uii.net\/wp-content\/uploads\/2019\/04\/satfinder.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"size-medium wp-image-2758 alignright\" src=\"https:\/\/www.f5uii.net\/wp-content\/uploads\/2019\/04\/satfinder-182x300.jpg\" alt=\"\" width=\"182\" height=\"300\" srcset=\"https:\/\/www.f5uii.net\/wp-content\/uploads\/2019\/04\/satfinder-182x300.jpg 182w, https:\/\/www.f5uii.net\/wp-content\/uploads\/2019\/04\/satfinder-768x1264.jpg 768w, https:\/\/www.f5uii.net\/wp-content\/uploads\/2019\/04\/satfinder-622x1024.jpg 622w, https:\/\/www.f5uii.net\/wp-content\/uploads\/2019\/04\/satfinder.jpg 1080w\" sizes=\"auto, (max-width: 182px) 100vw, 182px\" \/><\/a>If you are equipped with a smartphone, you may be helped by software that calculates the antenna direction according to your position, and even allows you to display on the screen, the theoretical position of the satellite in the sky in superimposition of the real vision taken by the camera\/video of your smartphone.

The beacon frequency is known and fixed at 10,489,800 MHz.<\/p>\n<p>We will immediately start the <strong>SDR Console<\/strong> option which allows the frequency stabilization: In the &#8220;<em>View<\/em>&#8221; tab, click on <em>Select<\/em> of the &#8220;<em>More options&#8230;<\/em>&#8221; button.<\/p>\n<p id=\"mMXRgcM\"><img loading=\"lazy\" decoding=\"async\" width=\"1267\" height=\"211\" class=\"alignnone size-full wp-image-2689 \" src=\"https:\/\/www.f5uii.net\/wp-content\/uploads\/2019\/04\/img_5cbdce16797c7.png\" alt=\"\" srcset=\"https:\/\/www.f5uii.net\/wp-content\/uploads\/2019\/04\/img_5cbdce16797c7.png 1267w, https:\/\/www.f5uii.net\/wp-content\/uploads\/2019\/04\/img_5cbdce16797c7-300x50.png 300w, https:\/\/www.f5uii.net\/wp-content\/uploads\/2019\/04\/img_5cbdce16797c7-768x128.png 768w, https:\/\/www.f5uii.net\/wp-content\/uploads\/2019\/04\/img_5cbdce16797c7-280x47.png 280w\" sizes=\"auto, (max-width: 1267px) 100vw, 1267px\" \/><\/p>\n<p>Check the line &#8220;<em>Geostationary Beacon<\/em>&#8221; and confirm with <em>OK<\/em>.<\/p>\n<p id=\"rdTRiYB\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-2690 \" src=\"https:\/\/www.f5uii.net\/wp-content\/uploads\/2019\/04\/img_5cbdce4d48521.png\" alt=\"\" width=\"453\" height=\"340\" srcset=\"https:\/\/www.f5uii.net\/wp-content\/uploads\/2019\/04\/img_5cbdce4d48521.png 752w, https:\/\/www.f5uii.net\/wp-content\/uploads\/2019\/04\/img_5cbdce4d48521-300x225.png 300w, https:\/\/www.f5uii.net\/wp-content\/uploads\/2019\/04\/img_5cbdce4d48521-200x150.png 200w\" sizes=\"auto, (max-width: 453px) 100vw, 453px\" \/><\/p>\n<p>Restart <strong>SDR Console<\/strong>.<\/p>\n<p id=\"GyNogHS\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-2691 \" src=\"https:\/\/www.f5uii.net\/wp-content\/uploads\/2019\/04\/img_5cbdce8550fd7.png\" alt=\"\" width=\"338\" height=\"141\" srcset=\"https:\/\/www.f5uii.net\/wp-content\/uploads\/2019\/04\/img_5cbdce8550fd7.png 441w, https:\/\/www.f5uii.net\/wp-content\/uploads\/2019\/04\/img_5cbdce8550fd7-300x125.png 300w, https:\/\/www.f5uii.net\/wp-content\/uploads\/2019\/04\/img_5cbdce8550fd7-280x117.png 280w\" sizes=\"auto, (max-width: 338px) 100vw, 338px\" \/><\/p>\n<h3>The feedback window to the BPSK beacon of QO-100<\/h3>\n<p>Return to the <em>View<\/em> tab and now click on the &#8216;<em>Geostationary Beacon<\/em>&#8216; button<\/p>\n<p id=\"LPKlwLo\"><img loading=\"lazy\" decoding=\"async\" width=\"1326\" height=\"235\" class=\"alignnone size-full wp-image-2692 \" src=\"https:\/\/www.f5uii.net\/wp-content\/uploads\/2019\/04\/img_5cbdcef920119.png\" alt=\"\" srcset=\"https:\/\/www.f5uii.net\/wp-content\/uploads\/2019\/04\/img_5cbdcef920119.png 1326w, https:\/\/www.f5uii.net\/wp-content\/uploads\/2019\/04\/img_5cbdcef920119-300x53.png 300w, https:\/\/www.f5uii.net\/wp-content\/uploads\/2019\/04\/img_5cbdcef920119-768x136.png 768w, https:\/\/www.f5uii.net\/wp-content\/uploads\/2019\/04\/img_5cbdcef920119-1280x227.png 1280w, https:\/\/www.f5uii.net\/wp-content\/uploads\/2019\/04\/img_5cbdcef920119-280x50.png 280w\" sizes=\"auto, (max-width: 1326px) 100vw, 1326px\" \/><\/p>\n<p>At the bottom of the screen is the window &#8220;<em>Geostationary Satellite Beacon<\/em>&#8220;.<\/p>\n<ol>\n<li>Start the waterfall of the Geostationary Satellite Beacon screen, by clicking on the first Start button (the circle)<\/li>\n<\/ol>\n<p id=\"ddXwuXy\"><img loading=\"lazy\" decoding=\"async\" width=\"1427\" height=\"179\" class=\"alignnone size-full wp-image-2693 \" src=\"https:\/\/www.f5uii.net\/wp-content\/uploads\/2019\/04\/img_5cbdd12e32555.png\" alt=\"\" srcset=\"https:\/\/www.f5uii.net\/wp-content\/uploads\/2019\/04\/img_5cbdd12e32555.png 1427w, https:\/\/www.f5uii.net\/wp-content\/uploads\/2019\/04\/img_5cbdd12e32555-300x38.png 300w, https:\/\/www.f5uii.net\/wp-content\/uploads\/2019\/04\/img_5cbdd12e32555-768x96.png 768w, https:\/\/www.f5uii.net\/wp-content\/uploads\/2019\/04\/img_5cbdd12e32555-1280x161.png 1280w, https:\/\/www.f5uii.net\/wp-content\/uploads\/2019\/04\/img_5cbdd12e32555-280x35.png 280w\" sizes=\"auto, (max-width: 1427px) 100vw, 1427px\" \/><\/p>\n<p>You should see the upper band beacon modulated in BPSK.

You then read live the delta of frequencies measured by SDR Console, the delta is the difference between the actual frequency and the expected frequency of the beacon.

The <strong>SDR Console<\/strong> software is really very pleasant to use. In addition to SDR processing for reception, it is also designed to be used for transmission with SDR transmitters such as LimeSDR or Adalm Pluto. But this goes beyond the first objective of this article, but perhaps it could be the subject of another article to follow. It would be: Transmit in SSB via QO 100 with a LimeSDR and <strong>SDR Console<\/strong>. I would like to thank Simon G4ELI for the development of this software of very high quality, stability and functionality.<\/p>\n<p>Feel free to share your experiences, remarks by using directly the comments below.
