[QUOTE="a33, post: 960606, member: 332642"] Why scan [B]channels[/B] (in plural)? You could also scan just one channel on your wanted satellite, to check if you get the right program. If not, scan a frequency of the neighbouring satellite, and see what you get; and repeat checking neighbouring satellites till you know how far east or west you are from the wanted satellite. Scanning is much quicker then! You just have to do your homework, as to receivable programs on neighbouring satellites. That's how I usually do it. Or, simpler, I wait till I am home on a sunny day, and use 'the [B]sun and tape method[/B]' for the central LNB. For that I use the website [URL='http://www.satellite-calculations.com/Satellite/lookangles.htm']http://www.satellite.../lookangles.htm[/URL] You have to enter: -site latitude -site longitude -satellite position (for middle of LNB arm) -date for time calculation Then the exact time is given for the sun having the same azimuth as the middle LNB on that day, both in local time and UTC time. If you fix some tape (or a string) from the top of the LNB to the top of the dish, the shadow of that tape should be exactly on the middle of the LNB-arm and the middle of the dish. Even a complete year-timetable is given, if you have bad luck and the sun doesn't show for days :(. (Out of the year-timetable you can also deduce the sun-outage days: the days with the transition above/below satellite, when you can check if the shadow doesn't get to unwanted places... :).) This way you are on the right azimuth, and you only have to adjust/try the elevation angle, to find the wanted satellite. When you've no central LNB at the middle of the arm, then alas.... you have some calculating to do (with the method described here: [URL='https://www.satellites.co.uk/forums/threads/multifeed-installation-and-exact-calculation-of-lnb-position.167435/#post-957569']Multifeed installation and exact calculation of LNB position[/URL] Also if your arm isn't fitted properly perpendicular to the dish, then this method isn't really useful. Isn't it nice to be an amateur.... You don't need expensive instruments! That is: I like it. You get to be inventive.... ;)! Greetz, A33 [/QUOTE]
