TGN Thai Satellite in UK

[jay-uk]

my wife's uk that signal has been breaking up each morning and clears through the afternoon. has anyone else had trouble with the satellite reception. has it changed settings or is this possibly my receiver/equipment on the blink. thanks for the help.

It's not advisable to cross-post the same or similar message across different Thai forums (it might get you banned).

Does your receiver have the option of displaying the Signal Level (as SNR) and Quality. Some are more specific and can display RF-level, BER (PER) SNR, MER.

While you may be receiving a strong-enough signal, the 'Quality' of the signal may be too low to interpret the digital data of the program stream, so when the Quality drops below a certain threshold you get noisy sound, and a frozen or broken images.

So try taking readings when it's not working and when it is.

Also, your dish could now be slightly out of alignment.

Sorry you haven't found any fellow users to compare signal quality.

yes, sorry i did post on another forum but had no answer so thought best to try here also.

i will check my signal to see if the quality is ok as you mentioned for both times of day. the dish has been positioned without any problems for 10 years but last couple of years there have been strong winds if that has moved it slightly. when the signal is bad the picture is breaking up and pixelating. but afternoons and evenings ok.

thanks for the help.

I don't know whether there have been changes recently.

Currently it is on Hotbird 13D which should be easily receivable with an antenna > 60 cm.

What antenna size do you have?

So really the first point is checking the signal level (as described) and probably adjusting the antenna.

The difference between morning and afternoon? Thats a difficult one.

Wheather situation? Morning fog, rain, clouds? Clear in the afternoon?

All that is only relevant if the signal level is "on the edge".

Could it be corrosionat a cable joint?

[jay-uk]

I'm getting an above average 70% approx: signal late afternoons and poor low signal mornings. If it was corrosion I would guess that the signal what be poor throughout the day and night so I'm guessing alignment of the dish, if no one else is having similar problems. It has been like this on mostly clear days so not caused by bad weather. I might have to bite the bullet and get a specialist to come out and check the dish position and see if something obvious is wrong with the equipment set up. Thank you for your comments.

Seems like the only variables involved are Time of Day, Temperature, Sun position ... not sure what else would change from mornings to late afternoon.

So, potentials:

TOD -- Microwave signal interference in the morning

Temperature -- LNB may be suffering from temperature differential

Temperature -- fringe alignment creating just enough offset to create issues

SUN -- focal passover causing excessive noise/interference (though you would think others' would suffer similar affect)

Very odd.
