Jamming on HotBird

[herrr]

If you have problems on some Hotbird transponders don't worry: your dish is not gone with the wind or your LNB frozen...
Some deliberated action of interferences is in progress on uplinks of 11240 V, 11727 v, 12226 V and 12597 V.
The situation is different time to time.
Electronic war, like once upon a time Radio Moscow and VOA on short waves...when I was younger...

hi herrr

thanks, but have a strange thing here: channels on 11727V are:
- no signal on box1
- signal ok on box2
-> same setup/dish ...

Re: Jamming on HotBird

I was wondering what was going on with this signal it is coming and going all the time making it unwatchable

Re: Jamming on HotBird

I had the same effect, then I changed cable at dish and signal was better and after that again worse. Are they testing something (signal strength, spots...)?
Another reason my be problems in the uplink.

Re: Jamming on HotBird

just checked, and seems to be back and ok now

Re: Jamming on HotBird

Hi...I didn't want to enter in details, not to flame political debate, that's OT.
Anyway, as far as I know, two countries, for different reasons, are angry with Eutelsat: first one for banning their channels, second one with news TVs (CNN, Euronews, BBC, VOA, TVE...) for their information about situation in that country (you can guess perhaps the last one, that looks to be guilty at present...)
Technically speaking is very easy to do: it's enough a transmitting station that shoots to Hotbird on the same frequency of the uplink and the results are the ones you saw, involving also innocent TVs, on the same trasponder of targets...
(receiving dishes on board of satellites of course look in different directions, to good uplink...but with strong power and jamming modulation it can be done...)
Something similar (in terrestrial - analogue - broadcasting) was made decades ago by terrorists in Italy, they entered with their messages in RAI relays.

Edit: @ pan1100: it comes and goes...

Re: Jamming on HotBird

I had a friend who called me to ask why they were receiving no signal on certain transponders on Hotbird... Perhaps this was the reason why? Is this not illegal to do however, why are they allowed to get away with it?

If the problem is similar to that one described, it may be.
About the fact that's illegal... there was only one way to make them stop, and it's quite extreme, satellites are vulnerable...

Re: Jamming on HotBird

As all ready said its back now but the signal is down to almost half of what it was before

Re: Jamming on HotBird

I ve also signals probles on hottbird from pakistan and some of HD channels frozen alot

Re: Jamming on HotBird

Hello,

Could it be possible to damage a satellite this way?
Geez, that's scary when you know the price of these toys :/

Re: Jamming on HotBird

Somehow I do not think that the countries who would be involved in this sort of thing
would be to bothered about what kind of sanctions that could be taken against them,
after all they show no regard for their citizens.

I have just switched on and was showing no signal then back up to S 86 % Q 94%
so still a few problems it seems

Re: Jamming on HotBird

From last week it showing that kind of problem. 11200 went slightly weak, 11727 become stronger sometime. 12597 also show some improvement in strength or sometime unwatchable. Because I am on the edge of the foot print, there is some improvement as whole in signals.

Maybe it's better to name names, so people know and can judge better.
Let them know that everyone knows what they are doing!

Re: Jamming on HotBird

Suspecting who is behind these problems and being able to prove it is extremely difficult
and even if you could you would be dealing with people who kill and maim innocent people on a daily basis without any provocation what-so -ever. do you really think they give a *amm about what anyone thinks.
