No-satellite signal, Televes multiswitch, Sky+

[nate]

Hi,

I live in an apartment building and am having difficulties with my Sky.
On most channels except for BBC, ITV, Channel 4 and Paramount Comedy 1 +1 I get the the 'No Satellite Signal' message.

The apartment building uses a Televés 7279 5x12 multiswitch to feed to 6 apartments (there are two of these for the 12 apartments).

After a lot of fiddling around I have found that I can get most channels (minus Sky Premier, Sky One, Two, Three, Paramount Comedy 1, 2, 2+ (although can get 1+1)) with the option for '22 khz command' switched to the Off mode.

Can anybody tell me what could be causing this?
What is '22 khz command' and is it OK for it to be switched off?

Thanks in advance,

Nate

FYI, I have been up to the roof to find the satellite and can only find this:

Sky minidish with single LNB.

Is this sufficient to feed to 12 boxes through 2 multiswitches?
Is this even possible? Do there have to be other satellites somewhere that I have not found? Or are we looking at a shoddy set-up here?

Welcome,

This setting needs to be ON and sends a 22Khz tone to the LNb OR in your case the multi-switch.

Check with other apartments to see if they are having similar problems to count out a receiver problem. You may after all have a band switching problem either with the switch OR a fault with the Quattro LNb. If this is the case your need to speak to the management company.

P.S...........This is not the dish feeding the switch. There will be a larger dish with 4 output type LNb.

This setting needs to be ON and sends a 22Khz tone to the LNb OR in your case the multi-switch.

But, if I switch this on, I lose 80% of the channels right now.

Check with other apartments to see if they are having similar problems to count out a receiver problem.

This I was intending on doing as I have spoken to the management company and they say that 'Nobody else has complained'. But, if you know management companies, like most, they aren't great.

You may after all have a band switching problem either with the switch OR a fault with the Quattro LNb.

I tried plugging my feed into the other multiswitch but found I had exactly the same problem.

This is not the dish feeding the switch. There will be a larger dish with 4 output type LNb.

Thought so, when I saw this I was a bit aghast and thought it could not be right, though not really supposed to be walking around the roof so didn't go too far around to look. Not really supposed to be playing with the multiswitch either, but, I'm getting frustrated as the management company are doing their best to not send out an engineer to look at it.

To sum up; sounds like a receiver fault maybe

Check the LOW BAND LO is 9.75 & HIGH BAND LO is 10.60 in the LNb set up mode

Thanks for the help SM, you wouldn't believe how stressed I've been getting over this in the last two months.

Check the LOW BAND LO is 9.75 & HIGH BAND LO is 10.60 in the LNb set up mode

It certainly is.

Last thing then, before I hop off to Sky for (hopefully) a replacement box (it's only 6 months old);

• When the 22 khz command is switched ON and I can only get 5% of channels, the signal test shows nothing (blank) for signal quality and strength and 'Not locked', but with 22 khz command OFF it has about 50% for each and Locked (and I can get channels).

• Sometimes, late at night (around 2 night a week, >9pm) with 22 khz command switched ON I DO get every single channel. But if I leave the box on, I wake up in the morning and they're gone again.

• It's probably not the multiswitch (as I have tried it in two) and the management company say no other reports of problems.

So, from all of that, you think box fault?

 

[satelliteman]

Does the other residents have a Sly box working perfectly ???

Just because there are no reported problems doesn't mean the system is OK; they may just be on terrestrial only.

If you turn OFF the 22khZ tone, the receiver will only receive LOW band H & V freq

If no one else has Sly, then consider an incorrectly wired multi-switch (if new) with cross polarities although from your description, sound like your box is ..ck.d

 

[nate]

Thanks for the advice.

I'll speak to other residents as soon as I can and find out if any of them have it. I only actually speak to two of them and know that they don't.

I'll let you know the outcome

Thanks again.

OK, would be interested to see what the outcome of this one turns out to be

I wonder if the OP found a solution . I have same issue when i turn 22KHz i get half channels and when i turn 22khz on I get the high band channels. also no one complained to the management company. i too live in a block of 6 flats and we have 2 feeds sky and hotbird. my issue is with hotbird as sky is directly connected.
