Page 1 Introduction Amstrad plc made it possible for the “man in the street” to purchase a low-cost satellite receiver in order to watch satellite TV programmes from the Astra satellite designated “Astra 1A”. The first receiver produced was the 16 channel SRX100 which did not have an internal decoder. This receiver was upgraded to the SRX200 which worked with a remote control handset. The SRX200 was later given 48 channels to cope with the additional channels from the Astra 1B satellite and from the proposed Astra 1C. Then the SRD400 was introduced, still with 48 channels and remote handset but also containing a Videocrypt™ decoder which is needed to watch the scrambled channels transmitted by "SKY Television". Later receivers such as the SRD510, SRD520, SRD540, SRD550 have proved to be somewhat less reliable than the early models, although they do have the benefit of additional features such as on-screen menus, additional audio frequencies and more channels. Compared with more expensive receivers, the SRD400 has rather grainy pictures and the audio does not use the true Wegener Panda™ stereo noise reduction circuitry. However, unless you are a very discerning listener and watcher, you are unlikely to notice the difference. In fact, compared with the average terrestrial television picture, the SRD400 satellite pictures are superb! So, no matter whether you bought this receiver new or at a car boot sale, you may be assured that you have got good value for money. Now read on to find out how to use and improve on your purchase:– If your SRD400 is not already installed you need our “How to Make Money from Satellite TV” guide which explains all about installing satellite TV systems with a minimum of equipment. Without following the professional methods described in the guide, you could make mistakes which will fail to get the best from your equipment or even cause damage. Assuming that your receiver is already connected to a properly installed dish, the following information will guide you in obtaining the best pictures and sound and in recording programmes on your video recorder. Connecting up The receiver, TV and Video recorder must be “chained” together by connecting them in a particular order and you can do this by using either coaxial “RF” cable with an ordinary TV plug at each end or by using a “SCART to SCART” cable. In order to watch recorded programmes you must connect the TV after the video recorder. In order to record satellite programmes, the video recorder must be connected after the satellite receiver. Page 2 So the line-up is as follows: • TV aerial connected into the satellite receiver “RF in” or “TV in”. • Satellite receiver “RF out” connected to video recorder “RF in” (or use a SCART – SCART cable from satellite receiver “SCART/ PERITEL” to the appropriate SCART socket on the video recorder). • Video recorder “RF out” to TV (or use the appropriate SCART connector between the two). There are more complicated ways of connecting with SCART cables or a combination of SCART and RF leads but the method depends upon the sockets available on your equipment. If in doubt, use the RF connection method to begin with. The advantages gained by using SCART are as follows: • No need to “tune” the TV to the satellite receiver. • Marginally better picture quality, provided that high quality SCART leads are used (some cheap ones can make the picture worse!) • Stereo sound from your TV (if it is equipped for stereo). You can also link the Left and Right stereo outputs to the “Auxiliary” or “CD” input on your Hi-Fi system. It’s not obvious to most people but your video recorder has a built-in TV tuner. In fact it is a TV except that it has no screen! You can prove this by unplugging your TV set whilst recording a TV programme. The video still works! This is why you must tune the video recorder in to each of the watchable TV channels when you first install it. It does not get pictures from the TV – it produces them from the aerial signal, direct. Your satellite receiver sends its programmes out of its “RF out” socket on one TV channel frequency (usually channel 38). You must tune your TV set to this channel and store it as button 6 (for instance). Your TV will already be tuned to the video recorder (usually on channel 5 or 0). With TV channel button number 6 selected you can now watch any satellite channel you care to select with the satellite remote control. Now, you must tune your video recorder to channel 38 and store this as number 6 (or Page 3 whatever number you wish). To do this, select the video recorder channel with your TV remote and select a satellite channel with the satellite remote. Now follow the tuning instructions for your video recorder and tune it to see the satellite channel on the TV. (It is easier if you flip the TEST SIGNAL switch ON in order to see the test bars on the TV screen when the video is tuned). Leave the satellite receiver switched ON to record the satellite channel which is selected. Channel customisation The receiver’s channels are factory-set to Astra satellite frequencies. The only way to reset your receiver to these values (maybe somebody messed up the settings or the audio disappeared) is to get an engineer to fit a new (blank) channel memory I.C. (SDA2516), which will automatically set the correct channels, or to tune every channel manually by pressing buttons. To do this, set channel 1 as the lowest frequency as follows: Select channel 1 by pressing the [1] button. Press Tune ▼ until the lowest number in the display is shown (about 0960). If you overshoot simply press Tune ▲ until the number is displayed. then press [PRESET] twice, to store this frequency as channel 1. Then press the following sequence repeatedly: [PRESET] [Tune ▲] [PRESET] then [Channel ▲] Make sure that each time you press [Tune ▲] the [H/V] light changes from on to off or vice versa; if it does not change, immediately press [Tune ▲] again then carry on with the sequence. This method puts the channels into transponder order. If you want them set with all SKY or English channels first you must customise each channel by pressing [Tune ▲] repeatedly until the required channel appears. The actual frequency displayed is only approximate and you must imagine a "1" in front of it so that it matches the channel frequencies listed in the satellite magazines. H/V This setting determines the channel polarisation: horizontal or vertical. The H/V POL setting can be adjusted between horizontal and vertical. You don’t really need to know what this means but the technically minded might be interested to know that when you select vertical polarisation, the receiver sends 13 volts up the cable to the LNB on the dish. When you select horizontal the receiver sends 17 volts. The LNB looks for the Page 4 appropriately polarised signal, reflected from the dish, according to the voltage it receives. In standby, the receiver turns off the LNB voltage. You will not need to change this setting for pre-programmed Astra channels but you may need to change it if you customise any channels to receive broadcasts from another satellite. AUDIO The AUDIO setting can be adjusted from sound tracks 1 to 7. Some channels use several sound tracks for different languages. For these channels, select the sound track with the appropriate language. Some channels use two TV sound tracks together to produce left and right stereo. Most channels also use some of the sound tracks for mono or stereo radio channels. For instance, you will find BBC Radio 1 to 5 on satellite in MONO but, because the SRD400 can not provide all of the available audio frequencies, you will not be able to receive them all. To select a channel for radio it is best to use channels 48 downwards, to avoid confusion. Find out what satellite TV channel carries the radio that you like and tune the picture in. Then press the [AUDIO] button to get the radio sound track and store it by pressing [PRESET] twice. FINE TUNE This setting determines the fine tuning of ALL channels to match a particular LNB on the dish. You may need to adjust it if some channels seem slightly off-tune despite their frequencies being displayed correctly in the menu (you will see either black "sparklies" or white ones on the satellite picture).

  • Arianespace Flight 130
    ARIANESPACE FLIGHT 130 ARIANE 5 TO LOFT TWO COMMUNICATIONS SATELLITES Flight 130 marks the third commercial launch of Europe’s new heavy launcher. Arianespace is the first company in the world to roll out a new-generation commercial heavy launcher, qualified for all missions. Ariane 5's debut commercial launch in December 1999 injected the XMM scientific satellite into an elliptical orbit. Flight 130 will loft the telecommunications satellites Astra 2b and GE - 7 into geostationary orbit. Astra 2B will be the sixth spacecraft launched by Arianespace for Société Européenne des Satellites (SES), following Astra 1A in December 1988, Astra 1B in March 1991, Astra 1C in May 1993, Astra 1D in October 1994 and Astra 1E in October 1995. Built by Astrium, Astra 2B will weigh 3,315 kilograms at liftoff. Designed to operate for more than 15 years, it will broadcast digital TV programs throughout Europe. GE-7, built by Lockheed Martin, will be the 14th satellite launched by Ariane for American operator GE Americom, following the G-Star, Spacenet, Satcom and GE series satellites. Positioned at 146 degrees West, GE-7 will primarily provide radio and Internet transmission services for North America and the Caribbean. 1. ARIANESPACE FLIGHT 130 MISSION 2.

  • LNB Mysteries Explained
    SatCure, PO Box 12, Sandbach, CW11 1XA, England Return to SatCure index page LNB mysteries explained Low Noise Block-downconvertor (so called because it converts a whole band or "block" of frequencies to a lower band). ============================ Is there actually a different LNB for prime focus dishes + offset dishes? Surely an LNB's innards are the same and the feedhorn or the C120 flange is the only difference? In the old days, LNB noise figures were high, the gain (amplification) was low and satellite transponder power was typically 20 Watts. Imagine trying to see a 20 Watt light bulb 24,000 miles away! (You'd have trouble seeing a 20W bulb at the end of a 24 yard corridor). So, an LNB and feedhorn had to be matched to the dish. The internal antenna of the LNB had to be at the exact focal point of the dish and the horn had to be flared in such a way that, with the LNB at the focal point, the . horn could "see" the exact circular area of the dish - no more and no less. If it was less then it wasn't collecting signal from the full area of the dish. If it was more, it was also collecting unwanted "noise" from any warm object (wall) or from the sky behind the dish. A good compromise was to take just part of a much larger dish and mount the LNB in an "offset" position. The curvature of this partial dish is such that the focal point is now much lower so the LNB and feedhorn no longer obscure the signal path as they would with a "prime focus" dish.
