I get low signal.
Stick is directly mounted to the wall mount.
Normal TV gives me good signal on same mount.

Hmm seems like the signal strength is strong enough (MER indicates that and the tuner locks onto the frequency).
However that the Signal Quality is so low indicates that there is some noise on the cable which the tuner cannot handle.
There can only be 2 possibilities:
1. Faulty tuner, which would be odd since the MER is already okay and those things are handled within the Chip itself.
2. Too noisy cable, problem with grounding
-
I have tried the stick in somebody else's home and read signal gave me 100%.
So indeed the cable must be noisy in my home, strange I have good reception on my TV.
How do I get rid of this noise. I have checked the wallmount, it is directly connected to my providers cable. The connection looks fine.
My provider's manual says "You should only connect the groundcable if your wallmount is in the fusebox". My wallmount is in the livingroom, I don't have an earth terminal to connect to. Please help me out.
-
You might try it with a notebook which is not connected to the powerline to see if that improves the situation?
I guess our upcoming DVB-C devices are more immune against such noisy lines. However you are also the first one reporting such an issue as far as I remember.
-
I tried the stick on my notebook without powerline, no improvements, same (bad) results. On some frequencies 40% and some 0%.
I have called my provider, but they won`t help me because the stick is not supported by them and my TV and internet connection provided by them work just fine.
Anny other suggestions, the stick is useless for me right now. :'(
-
Well you need to see that you can get the noise from the Cable, the signal itself is definitely strong enough.
You might try to get some adjustable attenuator (there are some cheap ones available on the market for a few eur).
Otherwise as mentioned we will have some newer models upcoming which are using a different chipset which might improve the situation for you. As mentioned you are the first one having that issue with such a tuner.
-
Is this a type of http://www.kleinspul.nl/index.php?productID=2703&cat=879 (http://www.kleinspul.nl/index.php?productID=2703&cat=879) you mentioned. For this amount of money I will give it a try.
Or can you give me some links to a such an attenuator (German webshops will be fine).
Thanks in advance.
-
Yes, that one might be okay. You might be able to find them a little bit cheaper I think
-
Used an attenuator. Didn't helped mutch. :(
-
Hello,
Any news about the tuner I send to you?
-
Yes, the tuner works perfectly, seems like you have some additional noise on your DVB-C line. We'll see if we can ship back another device with an upgraded chip version (but that's still no guarantee that it will help against the noise on the line)
-
Hello,
Any news about the tuner I send to you?
Did your new tuner work better? I bought a tuner this week and have many problems with frequencies between 420 and 460 MHz. All other work perfectly. My TV's (tested both) have no problem and good signals with this frequencies on the same outlet.
-
Haven't received my new tuner yet. So I can't tell you at this moment.
-
Hello,
When do I receive my new tuner for replacement?

My supplier changed the tuner for a new one and my problems are solved now. I hope you get your tuner soon.
-
They're on the way just to follow up here.

It would be nice if someone would respond.

"They're on the way just to follow up here."

Hello. Any news. Some reply please. No automated computer reply I hope now.
-
Any news????? ???
-
Checking again with sales/RMA. Last information was that it was shipped out. You'll receive an email from our sales person about further information about your shipping.
-
I haven't received a package and I havent received an email.
-
You should have received at least the email in the meanwhile... please doublecheck directly with sales/RMA the problem is that you are not directly in our customer base so there's no record about your order.
Normally the items have to be shipped back to the place where you bought the device and they will contact with us.
However our sales person will help to resolve your issue in that case.
