How To Set Up Channels On A Bbc Tv

Mar 13, 2012 | Section: Satellite

Hello dear readers of the site Today we continue the topic that began in the first post. So, we have all the calculated data, the antenna is collected according to the instructions and, already installed on the bracket, is waiting for its finest hour. Just in case, I found a drawing on the Internet.

Now we need to prepare the cable and connect the receiver. Let’s start with the cable.

We put on the cable F-connector.

The receiver and converter are interconnected by a coaxial cable, at the ends of which special connectors are installed, called F-connectors. How to properly cut the cable and install the F-connector on it, see the photo.

We retreat from the edge of the cable 1.5 centimeters, make a circular cut, and remove the top layer of insulation, it should turn out as in the figure (2). Here we see two layers of the screen. First, we bend back the layer of wires, and then of the foil, drawing (3). Now we retreat from the edge about one centimeter and make a circular incision on the protective layer. Carefully remove it, exposing the central core as shown (4). We take the F-connector, and screw it clockwise onto the cable. Be careful that no hair or foil of the screen touches the central core. It should turn out as in the figure below.

Now connect. We connect one end of the cable to the antenna converter, the other to the “LNB IN” input of the rear panel of the receiver. We connect the receiver to the TV with the cable that comes with the kit, according to the instructions for the receiver. Only now can they be plugged in. The receiver may have to turn on the toggle switch on the back panel. In the figure, it is highlighted in a rectangle.

Ways to connect the receiver output to the TV input.

There are two ways to connect the receiver output to the TV input.

The first, the so-called. high frequency, for connection of which a conventional coaxial antenna cable is used, connected to the “RF OUT” output of the receiver and to the antenna input of the TV. In the figure, such a connection is highlighted in a rectangle.

Then on the TV we start the function of automatic channel search for scanning the frequency range, and upon completion the receiver menu should appear on the screen.

The second method is called low frequency, for the implementation of which they use a cable having connectors of the “SCART” or “tulip” type.
We transfer the TV to the “video” mode with the “A / V” button on the remote control, and if everything is done correctly, the receiver menu should appear on the screen. In the figure, just this “SCART-SCART” connection method is implemented, where the “TV” output of the receiver is connected to any of the “AV1 or AV2” inputs of the TV. This is the same if you connected a DVD player to a TV.

Set up the receiver to search for a satellite signal.

If you turn on the receiver for the first time, a setup wizard will appear on the screen. We must agree with everything, but in the end, on his proposal to start searching for channels, click “No”, since he still will not find anything, the antenna is not tuned. Press the “EXIT” button on the remote control (remote control) of the receiver several times until it exits the setup wizard.

I will show the whole process using the example of a DRE7300 satellite receiver designed to receive channels of the TricolorTV package. The menu is standard for all receivers, and the difference may be insignificant only in design, or some menu items may be called differently.

Now we need to go to the main menu, for this we press the “MENU” button on the remote control (remote control) of the receiver. Further, all the time we will work only with the remote control of the receiver. Here we go down to the item “SETUP” and click “OK”. If you are asked for a “PIN”, enter four zeros.

In the “SETUP” window, we go down to the submenu “MANUAL SEARCH” and click “OK”.

Using this window, we will configure the antenna. If you purchased a ready-made kit, then the default values ​​do not change, as a rule, the provider and manufacturer take care of this, and all parameters are already “wired” into the receiver.
Here we are interested in the lower right corner, in which two settings scales are visible, I circled them with a white rectangle. Naturally, while they are empty and percentages are at zeros, since the antenna has not yet been tuned.

The upper scale shows the signal level from the satellite, and its second quality. And only when both scales they will show interest, we are on the right track, otherwise, nothing will be shown.

We will not go into details about polarization, flow rate, etc., I will tell about this to anyone who is interested in the following posts. Our main task is to tune in to the satellite and watch satellite TV.

The technique of tuning a satellite dish to a satellite.

So, once again we check all the connections, otherwise you will “turn” the plate for more than one day. Checked. Tighten the nuts that regulate the vertical and horizontal movements of the antenna so that it moves with some effort up and down and left and right, and without applying force it would remain motionless.

1. The first or coarse tuning of the satellite dish.

It’s best to tune in to the sun. We are waiting for the time of combining the satellite and the Sun indicated by the program, in my case 13.51, and when this happened, we direct the plate to the disk of the Sun so that the converter stands in the middle of the disk. If the weather is cloudy, or there’s no strength to wait for the sun, we take a compass, and, in the azimuth indicated by the program, we find the direction to the satellite. We expand the antenna so that the converter looks at a point on the horizon indicated by the compass arrow. That’s it, the first shot is done.

Now we take a thin marker or felt-tip pen and put a long risk on the mounting clip and bracket pipe as shown. We make two additional risks already on the bracket pipe itself, departing from central from the left and from the right to 5-7mm. If the shot was made by compass, then it is advisable to indent about one centimeter.

Risks are needed so that if during the setup process you get confused, tired or urgently called in to work, at any convenient time you can start searching from the starting position without making any more measurements. That’s precisely what the central risk is responsible for, and looking beyond the side is useless our companion is not there.

Starting position. the plate is directed up to the stop. For example, to the right from the central risks, we shift the plate by 1 mm, and begin to slowly lower it at intervals of about 5 mm. After each interval we make a stop for 2-3 seconds. Since the receiver is digital, he needs stops to process the signal. If you went down to the stop, and the signal level did not appear on the scale, raise the plate up, move it 1 mm to the right, and begin to lower it until the signal appears or all the way down.

We do just that, and in the sequence as I write. And, most importantly, do not rush. Everything will work out.
Keep in mind that the signal level on the scale at the time of adjustment instantly appears and disappears instantly. Therefore, be careful. This is especially true for those who are setting up a satellite dish for the first time. And if you are setting up with an assistant who should be standing at the TV and screaming about the appearance of a signal, even if it blinks every other time.

Suppose you have reached the right risks, and the scale is silent, well, she doesn’t want us to watch satellite television today, or your assistant still “missed” the appearance of the signal.
Then we can return to the initial central risk, and we can go left from it, but we can gradually return to it, i.e. from the right risks, we return back to the central one, continuing to search for the satellite, and at the same time we will double-check ourselves. Now, you have reached the left risks, but there is still no signal, again we return to the central risk, continuing the search. Means, you somewhere are mistaken or in a hurry. And remember, it’s pointless to go beyond extreme risks; our satellite is not there. Do not repeat the mistakes of others!

Oh, miracle, a signal level appeared on the scale, about which the assistant yelled so that the plaster fell and the balcony trembled. Everything! The first, crude setup you made. You can take a breath, eat schnickers and drink a cup of coffee.

2. Fine tune the satellite dish.

Now from this position we will finalize the antenna. To do this, grab your fingers on the sides of the plate in the middle part, and slightly begin to bend it horizontally left or right, monitoring the signal level, determining its maximum value on two scales. We move the plate to the place where the signal is maximum, but already holding on to its mount.

We do the same thing, but slightly bend the plate vertically, holding on to the bar on which the converter is mounted. Thus, moving the plate in two planes, we find its optimal position.

In addition, it is possible to raise the signal by a couple of percent if you turn the converter a few degrees clockwise or counterclockwise, after loosening the mounting of the converter holder.

Moving it to the mirror is not recommended, as it will change elevation, and all the settings will have to be done again. But usually if converter rotation angle set correctly, you do not need to twist it, because you still will not get a signal gain. Who forgot what the elevation angle and the angle of rotation of the converter, remember the first part.

Having reached the maximum signal value, neatly tighten the fastening nuts, which adjust the vertical movement of the plate. Keep an eye on the settings indicators. If the level has fallen, you will have to unscrew the nuts and again adjust the vertical position.

Now we tighten the fastening nuts that regulate the horizontal position of the plate as follows: first, tighten the left nut, for example, by the left nut, and then the right one, and so on.
If the signal level began to give, carefully, half a turn, unscrew the nut, which was twisted at that moment, and begin to tighten the opposite until the signal returns to its original value. In general, ensure that when the plate is fixed, the signal level remains at the same level as before tightening the nuts.

We search for channels.

Everything. Our antenna is tuned. Now it remains only to search for channels on the receiver. To do this, press the “EXIT” button several times until we exit to the “MAIN MENU”.

We go up to the sub-item “SEARCH FOR CHANNELS TRICOLOR TV” and click “OK”. The receiver will search for channels, and when it finishes, you will be asked to save them, which you certainly will. Happy viewing.
Good luck
