What should be my downlink frequency and symbol rate? No matter how you adjust the signal, it will not exceed 60%. The signal quality is 5%. I am He.
Is it Zhongxing 9 or Zhong 6?

If it is a satellite 6B C band.

The downlink frequency is 05 150, and the following parameters depend on the parameters of the TV channel you watch.

I take CCTV 10 as an example. 3840 H 27500(H is horizontal and v is vertical).

Generally, 60% of the signal strength is abnormal.

The most common consideration is that the line is too long. There is attenuation.

2. See if the copper wire in the signal wire connecting the satellite set-top box or tuner is long enough and has advantages. Copper wire with less gold will also cause problems due to poor contact.

3. That is, the parameters are incorrect, that is, the following parameters. It may be outdated or polarized in the wrong way. The polarization is wrong, it can be changed. If the parameters are wrong, just enter new parameters.

Joining the small pot of Zhongjiu satellite requires computer upgrade, because the so-called upgrade is to change PID. Maybe it's easy to change the PID in the cauldron. But the small pot can't be changed by itself, so it depends on the computer. This is called upgrading. SARFT will constantly upgrade the satellite in order to combat piracy, so don't scold SARFT. This involves commercial bidding projects. You ordinary people can't control it. What about America? You should be arrested in America. You broke the law.
