In areas where the signal is strong, skew is not such an issue, once outside the main reception area as with Astra 2D overseas, skew becomes important The LNB is locked in place by either a screw or a nut. If it looks like the problem is with the highest frequencies in the cable, starting at 2150 MHz and back downwards, try a new cable. Report from Los Alcazares, Murcia – 3 dishes, 1.25 x 1.37 offset dish – Most SD channels, No E4, no BBC 1 & 2 HD, 1.6 x 1.5m offset dish – All channels SD & HD 24/7. It is assumed that the polarisation as it leave the satellite is parallel to the earth's axis. Sony support does not know much (hardly anything about the subject), and I cannot find an answer on Google. Hope someone can shed some light, I'm running a SKyStar 2, motorised 100 cm dish and My Theatre and I'm chuffed with what I get, but I don't seem to be able to tune in properly to 19.2 east. However, satellites do not transmit in the way they are displayed on official footprints, so outside the intended reception area, it is mostly guesswork. Although it may seem just like another addition to the tracks of a hackathon, its upside potential is virtually unlimited. Using same dish 100km further east into 2x digiboxes, again in October 2013, yielded: BBC (1N) Strength 78-70% Quality 25-90% with lock and good reception. The first component in the chain would be the detector circuit and on a Universal LNB this would be a pin diode. Choose your location on the map; That's it! Service 30805. A few droplets of rain on the LNB can reduce the strength and quality of signals significantly, this is a major problem when receiving weaker signals. Which ever type of modulation is used, QPSK or 8PSK, they all use a form of Forward Error Correction (FEC). ks/s is 1000 symbols / second. Steady signal all day.But what about tonight??? They are often referred to as quadrature carriers. Service 30803. Located in Motala (between Stockholm and Gothenburg) I can say there is no big difference when I compare 2E and 2F regarding the UK beam. measurement of signal strength from the LNB to the receiver. The reason that a transponder having rather limited power, typically in the 8 to 150 watts range, can apparently have such a high EIRP stems from the fact that this power is not radiated equally in all directions and is concentrated in a narrow beam (Spotbeam) aimed at the earth below. It’s not an catastrophic situation …Changes in my receiver: BBC Three HD -> BBC Three (SD) Very close to the receiver threshold. In the case where the modulation scheme transmits 1 bit per symbol (e.g. S: 85-86, Q: 87-88 at 2F and S: 85-86 and Q: 88-89 at 2E. Astra 2E / Astra 2F / Astra 2G (28.2°E) - Radio stations - frequencies - KingOfSat This distortion will interfere with the reception of your signals. Lund, Sweden 1,5 – 1,6 m dish in central Lund. SEDS-VIT (Students for the Exploration and Development of Space) brings the first satellite development-based hackathon of India - Astra. Some modify existing LNBs by the use of fancy smoothing circuits to eliminate any further incoming noise from the power supply – there are definite improvements when used with cheaper receivers, especially those with switch mode supplies (few). BBC 1 London is 90/90% on the Humax Foxsat HD in the evening here, 90/80 in the afternoon. Low signal quality readings can result from many factors, improper dish alignment, old or poor quality LNBs and low quality or damaged coaxial cable. Low signal strength readings can be an indication that there is a problem between the LNB and the receiver, this could be caused by defective connectors or cable. It is less efficient, with not so much data available to transmit the picture. Optimum NF is probably in the middle of the band 10.7-12.75 GHz. In the northern hemisphere, sun outages occur before the March equinox (February, March) and after the September equinox (September and October). Forward Error Correction (FEC) is a technique used for controlling errors in data transmission, FEC is accomplished by adding redundancy to the transmitted information using a predetermined algorithm. Also, a diagram of the ideal positions, signal space diagram, in a modulation scheme can be called a constellation diagram. The Astra 2E transponders are weaker compared to Astra 2F transponders. The effects of a sun outage range from partial degradation (increase in the error rate) to a total destruction of the signal. When you have a large dish looking at high power satellites, the gain can be so high that the receiver is overloaded with signals. The Symbol rate is measured in baud (Bd) or symbols/second. The satellite appears to be tilted as viewed from Earth, this means the LNB has to be tilted to a similar angle so that it matches the geometry position of the satellite. The receiver should operate with signals up to 100%. 3.1 mtr dish, Echostar HD box getting most channels including BBC1 London, but having to use regional variations for others, signals are from both Astra 2E and 2F. This determines how much of the weak signal from the satellite is gathered for the LNB. Theoretically, the lowest noise figure obtainable from any device is limited by any components in the signal chain with the highest thermal noise. Very happy I’m not going to need the 1.8 m glassfibre dish I had waiting as a possible replacement if the signal was not strong enough! Signal: BBC 1 HD 10847 V S 55%, 8.62 dB / BBC1 London 10.773H 61%, 9.38 dB, BBC 1 HD 10847 V on 1N snr 73% dB 11.38 now on 2E snr 55% dB 8.62, All channels Astra 2 E good signal north Sweden Östersund no problem 3.70m Dish. CNR (also C/N) is the carrier to noise ratio. Listed below are reception reports for the Astra 2E satellite positioned at 28.2° East. Viewers within the central footprint in the British Isles and nearby Europe should not be affected, those in fringe areas will lose the signals from Astra 2E, Astra 2F and Eutelsat 28A. With 16 transponders, Astra 1A was the first satellite intended for DTH reception of satellite TV across Europe. The points on a constellation diagram are called constellation points. I have confirmed that my LNB is less sensitive for the verticals (approx 1.5 dB) so I’m now consider to turn it 90 degrees. Checked out the reception on BBC channels at 7.30 this morning, seems that was just when they started to switch to 2E! Official satellite reception maps (footprints), have very conservative values, this is good if you are inside the official reception area, as it is easy to determine the dish size required for reliable reception. Launched in 1988, Astra 1A was the first satellite in the Astra 19.2°E group. This enables channels to be broadcast free-to-air, with reception effectively constrained to the British Isles, it is used to provide channels to both the Freesat and Sky satellite platforms. Measured constellation diagrams can be used to recognize the type of interference and distortion in a signal. Hopefully I will hopefully get back the HD channels. Low signal strength readings can be an indication that there is a problem between the LNB and the receiver, this could be caused by defective connectors or cable. Over all seams Astra 2E signal about 2 dB weaker than Astra 2F UK Spot beam. All BBC working fine no loss as of yet. Temporary Obstruction of Satellite Dish – Scaffold etc Reception of all Astra 2E UK spotbeam channels. NID 1 $ encrypted. DVB-S, QPSK, FEC: 5/6, C/N at QEF: 7,5 Inside a satellite’s footprint, LNB skew is not all that important, however as you approach the fringes of the signal footprint it becomes ever more crucial to getting good reception. BPSK) then Es/No and Eb/No are the same. Reports suggest that a 1.8 m dish gives reception of the Astra 2E UK spotbeam 24/7 (NOT CONFIRMED). SR and FEC change from 22 MS/s 2/3 to 23 MS/s 3/4. DVB-S2, 8-psk, FEC: 5/6, C/N at QEF: 9,4 The range of gain specified is between 40dB and 70dB (somewhere between 10,000 and 4,000,000 times the incoming signal power). January 2, 2019 12.12 Europe/London By Jörn Krieger German public broadcaster ARD will transmit its complete TV channel portfolio in HD quality for DTH satellite households via Astra (19.2° East… :DSimilar trial in October 2013 in same location but better weather for historical comparison purposes: Channel 5 (Astra 2F) and BBC (Astra 1N) Channels Strength 51-80% Quality 51-28%; Lock quickly found with good reception. The receiver should operate with signals up to 100%. This is the signal strength of the Intermediate Frequency (IF) output from the LNB. I have tried to find the free german channels from ASTRA 19.2 E om my KDL-46W905A, but I have had no luck until now. Upon reception of the signal, the demodulator examines the received symbol, which may have been corrupted by the channel or the receiver (e.g. Low signal quality readings can result from many factors, improper dish alignment, old or poor quality LNBs and low quality or damaged coaxial cable. This prevents the picture breaking up. All these reading as done with a Inverto White Quad LNB , which has been chopped and glued to a C120. My current setup is a Gibertini 150, Inverto Black Ultra and a Pace 2600. It seems 150cm to 180cm is the minimum size of dish required as was the case in Astra 2D days here in west Sweden. BritBox launches in Australia 23rd November 2020; TNT launches on Freeview 19th November 2020; POP Player launches on Freeview Play 17th November 2020; Successful entry into service of Eutelsat Konnect Satellite 16th November 2020; Talia adds Ka-band spot beam covering the Levant Region 12th November 2020 A FEC of 9/10 means that just one-tenth of the data is used to correct errors, making the signal harder to receive and much less robust. ... 16th August 2019. With my 180 cm dish I get a good reception margin that can handle poor weather conditions. At Ku band, the detectors are rated at manufacture to about 40K which converts to a figure of 0.5 dB. A larger dish is required for reliable reception at this location. Reception: Intermittent reception and breakup. Reception report frtom just acrosss the water from you. All BBC, ITV & all C4 gone as of this morning. Kartina Satellite Provider. In areas with significant rainfall, using a LNB protector (LNB umbrella) will protect the LNB from rain, frost, dew and snow. EIRP levels refer to the power of signals measured at the satellite downlink antenna. Listed below are reception reports for the Astra 2E satellite positioned at 28.2° East. Some simply take the lowest noise figure during tests at a particular frequency and then claim that this is the figure of the LNB (so you could have a 0.5dB LNB at 10.8GHz which has a 1.1dB noise figure at 11.6GHz, however, it will be rated at 0.5 (depressingly common). Face towards the satellite in the sky. DVB-S2, 8-psk, FEC: 9/10, C/N at QEF: 11. The effect is due to the sun’s radiation overwhelming the satellite signal. BBC World News Europe HD is available free-to-air on satellite Astra 19.2° East (same satellite as Austrian and German channels). Consequently, bit errors can be tolerated up to a particular level without causing quality degradation of pictures or sound. The Freesat electronic programme guide is broadcast from the Eutelsat 28A satellite situated at 28.5° east. Signal strength is the percentage of signal to noise ratio, the measurement of signal strength from the LNB to the receiver. Dish No.1 SMW OA 1400 polarmount FEEDHORN: SMW XM-140 LNB: Inverto Black Pro nf 0.2, RECEIVER: DM 7020HD & Moteck V Box II 36V, Receiver: Humax Foxsat HD & MegaSat HD500. Reception is a tiny bit weaker as 2F here some 20 km southeast of Falun with a signal quality of 20-30%. Yesterday evening i had all channels with ca. Each satellite has a transponder number which is what a self seeking system looks for the problem is it gets changed now and again which doesn't affect domestic systems as the satellite stays put as does the house but for mobile systems they need to know the new number. Viewers within the central footprint in the British Isles and nearby Europe should not be affected, those in fringe areas will lose the signals from Astra 2E, Astra 2F and Eutelsat 28A. A constellation diagram is a representation of a signal modulated by a digital modulation scheme such as quadrature amplitude modulation or phase-shift keying. Since then I am getting a little pixelation on the BBC horizontals, but have lost Channel 5 completely (which is normal). It is finding Astra 28,2,E, maximises the signal but when it checks the satellite, it must think it is the wrong satellite because it then starts searching again. 1. DVB-S, QPSK, FEC: 7/8, C/N at QEF: 8,2 Rotate it one way or the other until the signal quality is maximised. All channels now watchable without any drop outs, even in the light rain and heavy cloud we had today.My position is in S Villie, Rydsgård, about 15 km from the south Swedish coast and about 50 km east of Malmö. All geostationary satellites are located above the equator (the Clark Belt). For the broadcaster, 9/10 means that more channels can be squeezed in, at a higher data rate. It is typically measured at the output of the antenna or the input to the demodulator. Presently the LNB market is active by those selling what appears to be an extraordinarily good device, some use the best of the component batch – and end up with good performance overall (rare). LALIGATV BAR. Peter should soon fill us in anyway and his usually very accurate. Used the satellite finder supplied to find the Astra 19.2 satellite, which is facing south, 9 degrees to the right of where the 28.2 dish is pointing, is was easy to find. Astra plans to launch its two-stage, 38-foot-tall (12 meters) Rocket 3.2 from the Pacific Spaceport Complex on Alaska's Kodiak Island between Dec. 7 and Dec. 18. Most of the (HD) channels I want have vertical polarization. Went out with my sat meter and checked dish alignment ( we’ve had some pretty strong winds this winter) but it was OK. Then tried adjusting the LNB position and skew. Dishes are usually sized by their diameter, so size can be confusing if you are not comparing dishes of the same shape. Modualtion and SR change from DVB-S2 8PSK 30000 to DVB-S2 QPSK 29500. When it comes to the PE beam 2E is a little bit stronger than 2F. Preparations for the November 28 launch of the Astra 2G satellite aboard a Russian Proton rocket have been suspended in the face of persistent questions over whether Proton’s previous launch was as successful as claimed, industry officials said. This could be the difference between a good watchable picture or poor reception. This morning I woke to a loss of BBC (ex 1N) Verticals but Horizontals (except HD) were OK. Channel 5 from Astra 2F was also OK. By representing a transmitted symbol as a complex number and modulating a cosine and sine carrier signal with the real and imaginary parts (respectively), the symbol can be sent with two carriers on the same frequency. Interpretation These can ‘swamp’ the lower powered satellites signals. In some situations, as with overseas reception of the Astra 2E and Astra 2F satellites, the dish is simply not large enough to provide a signal that exceeds the satellite receiver threshold for reliable reception. Documented Satellite TV charts dedicated to European viewers. The Astra 2E satellite is copositioned at 28.2° East along with Astra 2F, the satellite is used by the main British public service broadcasters, the BBC, ITV and Channel 4. Effective Isotropic Radiated Power (EIRP) is derived from the word isotropic which means equal in all directions. In the northern hemisphere, sun outages occur before the March equinox (February, March) and after the September equinox (September and October). Receiver: TBS6925 (Single DVB-S/S2) & TBS6985 (Quad DVB-S/S2). The Signal Quality reading on the receiver is displaying the receiver Bit Error Rate (BER) from the satellite – and how much, or how little error correction is taking place. I have stable reception of all Astra 2E transponders here in Falkenberg on the Swedish west coast with my old 180 cm Luxor primefocus dish. Russian and Ukrainian channels. Modualtion and SR change from DVB-S2 QPSK 27500 to DVB-S2 8PSK 30000. SNR (also S/N) is the signal to noise ratio. But when it comes to Astra 2E I can only receive horizontal transponders with a 100 cm dish, to get stable reception of the vertical Astra 2E transponders a 120 – 150 cm dish is needed in Falkenberg. Astra 2F, 28.2°E. Loosen these and it will be possible to rotate the LNB left or right. Receiver: Humax FOXSAT-HD & Bush BFSAT02SD. A dish need only be about 40% wider to produce twice the signal; a 1.2 M dish will give nearly 50% more signal than a 1.0 M dish. Signal levels pretty much unchanged. Lost BBC News and all HD channels except Channel 4 and BBC News, also can get some plus 1s but not the original channel. Dish size is paramount in the reception of weak signals outside intended reception areas. List of Television Channels at Satellites 19.2°E Astra ... Satellite Astra 1KR. Along with other conventional tracks, CUBESAT forms a major part of our hackathon. The Astra 2E satellite is copositioned at 28.2° East along with Astra 2F, the satellite is used by the main British public service broadcasters, the BBC, ITV and Channel 4. BBC breaking up heavily, a larger dish is required at this location. 3- Centre conductor is too short and not making a reliable connection ‍ If you need help performing common coaxial cable terminations please see out DIY Video guides . The result is therefore a slightly pixelating picture that probably is going to get worse in the day with the normal pattern of the footprint. Still got cloud cover but it is not looking good. Sky Digital: New frequency for BoxNation: 11081.00MHz, pol.H (DVB-S SR:22000 FEC:5/6 SID:50301 PID:2305/2306 English- VideoGuard). BBC 1 HD is 90/80 evenings and 90/70 for a few hours in the afternoon. Hi, to let you know that I have 2.4m dish and have not lost any channels. DVB-S, QPSK, FEC: 3/4, C/N at QEF: 6,5 In order to locate 28.2°E - Astra 2A, Astra 2C, Astra 2B, Astra 2D with Sat-direction, all you need to know is where you are and know how to look at a map. DVB-S2, 8-psk, FEC: 4/5, C/N at QEF: 7,9 This is a measurement of the Bit Error Rate (BER) of the received signal from the satellite. To let the demodulator in the receiver work effectively, the gain at all frequencies, should be the same. I also have a slight feeling that the LNB is less sensitive when you go down in frequency. All of the BBC’s  domestic radio stations which are on satellite, use Astra 2E. A coherent detector is able to independently demodulate these carriers. The UK Spot beam provides maximum signal (for 45 cm dishes) over the UK and Ireland with a sharp roll-off of signal level outside this region. Sky channels on the three Europe beams are stronger than before in most of the continent, though there have been exceptions, such as in the eastern Mediterranean. A FEC of 2/3 means that every third bit of data is used to correct errors in the previous two bits. The service was formed as a memorandum in 2007 and has been marketed since 6 May 2008. There are many factors to consider in the satellite signal chain, they can all affect how much signal is received by the receiver, thus reducing the quality of the picture and sound. It is a measure of how “good” the signal is and how “easy” it will be to demodulate the transmitted information. At first sight, the highest gain you can get would be the obvious thing to look for; however that is not the only criterion when it comes to LNBs. Es/No is the ratio (usually in dB) between the energy in 1 symbol of a transmitted digital signal to the thermal noise power (kT) in 1 Hz. I have fitted a new LMB just in case. ALQUILER HD. Effective Isotropic Radiated Power means the power levels that would be received at any location if an antenna were radiating equally in all directions. Signal quality readings are usually between 60 to 80% and will provide good quality picture and sound, corresponding to a low Bit error rate. They are placed here to match the rotation of the earth. Viewers within the central footprint in the British Isles and nearby Europe should not be affected, those in fringe areas will lose the signals from Astra 2E, Astra 2F and Eutelsat 28A. DVB-S2, 8-psk, FEC: 3/5, C/N at QEF: 5,5 The real and imaginary axes are often called the in-phase, or I-axis, and the quadrature, or Q-axis, respectively. Previously good signal at 1.80m, Soyuz Flight VS24: Mission success at the service of the United Arab Emirates, Successful entry into service of Eutelsat Konnect Satellite. All of the BBC’s  domestic radio stations which are on satellite, use Astra 2E. Thus it will demodulate incorrectly if the corruption has caused the received symbol to move closer to another constellation point than the one transmitted. WEATHER – GREY, Rain/Snow -2.5c. They are a set of modulation symbols which comprise the modulation alphabet. Here signal would be more robust and can be received easier, with less breakup in rain, for example. European beams on Astra 2E/2F from Rotterdam to Baltic Sea • Satellite name and angle (i.e. Astra is the brand name for a number of geostationary communication satellites, both individually and as a group, which are owned and operated by SES S.A., a global satellite operator based in Betzdorf, in eastern Luxembourg.The name is also used to describe the pan-European broadcasting system provided by these satellites, the channels carried on them, and even the reception equipment. Soyuz Flight VS24: Mission success at the service of the United Arab Emirates, Successful entry into service of Eutelsat Konnect Satellite. I get an Astra 12032 H but using the latest transponder listing I cannot get anything else. Effective Isotropic Radiated Power (EIRP). Therefore, a 37 dBw EIRP reading means that a perfect antenna would direct 37 dBw or 5012 watts per square meter in all directions.
