Frage von LucatONI:
Hi having problems with my analogue satellite reception, had no problem receiving the following Channel: Sat1 RTL PRO7 Eurosport, the Fourth, rbb, 3sat, phoenix, HR3 but the other is completely non-existent, yet neither ard zdf wireless vox etc ... there there is no signal on the manual set frequency ... what is this and how can this be changed?
Antwort von Emil:
@ lucatION!
I now have no frequency table by the hand.
Are perhaps all empfangberen in a transmitter (eg H) polarization?
The non-receivable channels in V polarization?
Proper polarization set?
Switching voltage is available and sufficient?
Proper satellite?
And?

jepp.das sounds completely missing plane.
Antwort von Tersil:
which means missing plane and how to fix that.
a tenement and sattelitenanlage was already installed?
or is it s.receiver, then I have actually already tried everything;
Antwort von Chaintrooper:
Or you have an LNB S.2 receiver. If both Receiver off, then you are missing half the channels s.einem receiver.
Antwort von gatsby:
how did you resolve the problem?
Antwort von matsaeh:
Hello, have a similar problem.
I'm in an apartment with an analogue LNB on the roof pulled. I have an analog receiver and manual concern channels programmed (program scan, the device is not, - /
A few days later I just get even with Channel v. Pol., With no h. Pol.
Can the receivers with the other tenants hang together?
What can I do? Can it be so bad to ask their receivers for me always to leave ...

Can the receivers with the other tenants hang together? It was with the LNB supply voltage to be done. For the horizontal plane s.Receiver about 18 volts, for the vertical about 13 volts. Somewhere in between the multi-switch has a switching threshold. If not enough tension or tribunal (eg due to long cable, moisture in the times or other defects), the multi-switch to vertical.
Could be that the "supportive" of other participants voltage feeder synonymous for you switch to enable horizontal and if the other receivers are then made, you are limited to vertical.
With some receivers you can adjust the tension. It might even help, 19 or 20 volts, in order to offset the error.
Otherwise, the only systematic troubleshooting.
And obviously, in the foreseeable future, the plant digitaltauglich (ie, synonymous for high-band fit) will be converted, because the exclusive analogue reception is today not a state anymore. Even the stingy landlord will sooner or later to view.
Antwort von DWUA:
Hello beiti,
actually it is true that the digital systems insensitive
against disturbances such as rain and other bad
Weather influences are?
Antwort von deti:
Yes, that's true. In the case of a SNR, which is analogous only a noisy picture with many black and white score would see, is still a digital signal dekodierbar faultless.
This is not because no errors arrive at the receiver, but s.der error. For DVB-S as one speaks of a Forward Error Correction (FEC). The FEC is based on two different procedures that are mutually complementary: First, a Reed-Solomon code on the data made, on the other hand, a so-called Convolutional encoding is used. The Reed-Solomon code protects against so-called burst errors, ie momentary dropouts and the Convolutional coding produces entanglement (interleaving) of payload to the influence of burst errors is minimized.
As a rule, for a DVB-S transponder, the FEC rate of Convolutional encoder manual s.Empfänger set. Here are typical values 5 / 6 or 3 / 4, which is the ratio of payload to gross data rate corresponds.
When subsequently introduced DVB-S2 procedure, no Reed-Solomon code used - here come the so-called turbo codes are used. These are much more effective and allow much higher data rates at the same RF bandwidth.
Sodala, that was a demolition on DVB-S and S2 - Any questions?

Antwort von beiti:
If we have the basics durchkauen, one should perhaps add something, because this is often a misunderstanding arises: Whether the receiving digital or analog, is not exclusively s.Receiver and s.LNB. LNBs are neither analog nor digital. If you (technically totally inaccurate) of a "digital LNB" talking, an LNB is meant, in addition the so-called high band (ie at frequencies above 11.7 GHz) can receive. In the high band is the most German-digital channels. But there are synonymous in Lowband digital transmitter (eg, arte, Phoenix, Eins Extra, Bibel TV), and they can be with old LNBs already received. Conversely, you can with the new LNBs remains the Lowband and thus all the analog channels and a retooling of the plant would not be equal to all tenants to purchase Digitalreceivern of force - if a reason should be the landlord of the date of retrofitting has held.
Further information on upgrading, there are
Antwort von matsaeh:
Thanks for the reply, beiti!
Maybe I am not clear: For manual programming, I have all the desired channel set (and receiving), which I wanted, both horizontally as vertically polarized synonymous (the so-called?).
But after a few days, all slots in which hor. Pol. appears only noise or bluescreen. Can this still with a long cable to hang together? Or moisture or something?
The cable between the receiver wall and I have already exchanged, but this brings nothing.
Antwort von beiti:
But after a few days, all slots in which hor. Pol. appears only noise or bluescreen. Can this still with a long cable to hang together? Or moisture or something? Yes, it can be. If the plant is old and witterungsgeschädigt, moisture can penetrate at times, so that a portion of the discharged voltage (without having a complete short-form). Or maybe you had s.Anfang only luck that it is synonymous housemates had their receiver. It may well be that with another receiver (the voltage is stable up) the problem does not occur, but remain distant from all this speculation, you should spot s.verschiedenen Make measurements make the error.
The fact remains that the receiving system should be urgently upgraded. And it could then cause synonymous to go search.
