Can no longer receive TVP Info Wrocław on digital DVBT

Picking up HD channels now suddenly, but have lost TVP Info Wrocław. Have TVP Info Opole but Wroclaw has vanished. Any ideas why? Aerial/antenna is still in the same place.

I have moved the aerial now to see if I could get TVP Wroc back but no luck - instead on retuning I have an increased list of channels (excluding TVP Wroc) including Polsat and Polsat News but the screen says "scrambled channel" even for these free to air stations.

Any ideas what's happened? TVP Wroc is useful to me.

They moved it from mux3 to mux1. Scan channel 64 manually, 818MHz, horizontal polarity.
Transmiter is located on Slężą.


these streams are broadcasted for mobile devices not tv sets.

Thanks Peter, I will try to do that.

I should perhaps also add that maybe Polsat etc is not free on DVBT, only free on analogue terrestrial

Not successful :o(

Can't see how to switch to mux1 etc - scanned 64 (818mhz) but nothing found. No other options there.
Model is a Hyundai DVBH 331.
Spec: IF bandwidth 7mhz & 8mhz, input frequency 170 - 230mhz, 470 - 860mhz

I can't see how to make it scan 64 differently - the way it is scanning now it finds 0.

According to Wikipedia en.wikipedia.org/wiki/Cyfrowy_Polsat
these are the free ones on Polish digital TV

TVN7
Polsat Sport News
TV6
TV Biznes
Euronews
TV Puls
TVS
TTV
Mango 24
Tele5
TV5Monde
TVP1HD and TVP2HD
TVP Historia

I have I think TVP Historia and Kulturia, TVP Opole, TVP 1 & 2 HD, TVP Polonia, and used to have TVP Wroclaw.

There are quite a few others (excluding Wroclaw) but they say "scrambled" and do not play out, although their EPG does show.

I don't think I can unscramble the others as the tuner unit does not have a facility for a card or code to unlock premium channels.

Its possible (maybe due to the weather) you are picking up a different transmitter. You can easily receive from150km away and now they may have boosted transmission power to make it possible. Find out where your aerial is pointed - it may have to be re-aligned = what transmitter should you be aiming for?

Its a test for the 8 channel 20pln a month Polsat service

Thanks

My set top box doesn't pick anything up from there. I am using a 42dB gain high quality powered indoor aerial that was fine before - now any adjusting of its position does not bring back TVP Wroclaw. As for the other free channels, most of them were never shown on the screen list.

- I confirm I have the TV1 & 2 HD and Polonia TV - but TVP Info Wroc is gone.
This happened a few days ago when the weather was sunny and is the same with the rain now.

Just checked again: I am receiving TVP Info Opole and all the others only on 570mhz bandwidth 8mhz 98-100%. No other transmitter is being received. Corresponds to this transmitter only: radiopolska.pl/wykaz/pokazdv_nadajnik.php?pid=592

I can't find a position for the aerial where it picks up any other transmitters. There are too many large buildings nearby perhaps.
Analogue reception is pretty poor so not worth bothering with here either.

You are using an indoor aerial ?

I'd say it highly likely you are pointing at the wrong transmitter. Find the correct transmitter and make sure you are aiming for it.

here ?

You are probably picking up the Opole transmitter which, if you are in Wroclaw, will be in the same direction.

Point to the correct transmitter, the arial will have a 20 degree wide band. Alternatively switch off the amplifier and use a poorer quality arial

Thanks for all those links!

It's a quality indoor aerial, pretty much as good as they get. The block doesn't have a working roof aerial. If I turn off the amp, I get nothing, reception here is very poor due to nearby taller buildings (eg ghosting, noise, etc)

It doesn't matter where I position the aerial, it either picks up 570mhz or nothing.

Looks like I'm stuffed until I move out to Bielany or similar, where the TV reception is very easy to do.

In that case be happy you get anything.

Yes, at the back of the Polish language section of the instructions booklet, where it says Problem - tall building(s) around, I can only receive a few channels - under the Solution column it says Sir is lucky to receive anything then. Get cable, or sir is a tighfisted loser. Cut back on the mature cheddar and buy a TV package.

So, thank you TVP Wroclaw for changing how you broadcast if that is the case - causing me and probably many others in parts of Wroc to do without our local channel on DVB-T unless we fork out for cable.

LOL, Sod the TV, keep eating Cheddar.

Don't blame TVP, its Emitel responsibility entirely.

Actually, all they probably did was boost the signal from Opole. Anything could have changed - the signal may a have been bouncing off a structure that is now gone, or your reciever may refuse to connect to the feeble reflected signal from Wroclaw when it can get a clear signal from another transmitter (which is very close by the way)

Keep scanning, the local weather may not be the issue but that of the ionosphere where radio signals bounce.

Quite right, after all it is Cathedral CIty, frankly I don't want to give it up :o) (Memo to mods: I do not work for Dairy Crest!)

I'm just guessing, but for example I can get Polsat Sport News listed on the channels but not receive it - screen says "scrambled channel". PSN is not scrambled, it should be free to air. Polsat Sport Extra is scrambled but not the other one. I reckon I am getting "scrambled" for the ones that are too weak too, because it's getting just 55% quality on PSN. TVP Wro has vanished completely of course, probably for the reasons you describe.

Anyway I knew using the word scrambled would get me hungry, so the frying pan is coming out and DVB-T will have to wait for another day :o)

Everyone is receiving these scrambled channels, you will have to buy a Polsat subscription to unscramble them. Nothing to do with your issue... probably not.

I think that some of the channels being shown as scrambled aren't in reality although most are. Where the box says scrambled the signal is under a consistent 90% which seems to be the minimum for some sort of reception. No doubt some of the channels will not display even if the signal were 100% because they are scrambled although probably the screen would show an advert for getting the station unscrambled.

If I were staying in this flat I'd buy an outdoor aerial and clip it to the balcony but I'm moving I hope so won't bother. Probably even then, I won't get TVP Wro as it's completely vanished.

Thanks again for the help and advice.

Nope. I have got a good picture at 14% signal. None of my signals are over 50% and they are all perfect,

Well, that's interesting! Where I do have a station (eg TVP Opole, TVP2 HD etc) the signal is 90-100%. I'm going to get an extension coax lead tomorrow and pop the indoor aerial outside for a test and see what I pick up. In the past I've aligned satellite dishes without a meter, so if I can do that then I'll find any signal that's out there because don't have to be anywhere near as precise with this antenna as I had to be with the sat dish in the UK when I installed it

Quick update for anyone who needs this info...

By moving the amplified aerial outside, TVP Wroclaw can again be received although it's weak compared to before, about 65%.

Can also receive intermittently TV6, Eska, Polo, TTV, etc. Not Polsat Sports News, however.

Can also manual search and see if anything is to be found because a bar on the screen gets colourful if there are signals there. Mostly there's nothing receivable, save the above.

What needs to be done is of course to fix an outdoor aerial with probably amplification, I think conventiona; aerials have a degree of gain built in but I am not sure. (With the gain/amp off, nothing is received with the indoor aerial whether in or out.)

Now I've lost TVP Opole, Historia, Kultura, TVP2 etc. A search for channels now brings up Polsat News and others but they're apparently "scrambled" and there's nothing showing on the list as free to view.

Have they turned another transmitter off, or is this a local issue? I am near Skytower.

I wonder what you need them all for once you've stated in your profile that you don't know Polish. Are you a fan of silent TV (or rather "language-unknown TV")?

You'll have to go on wondering then won't you.

TVP Wroclaw and TVP Opole both gone, Wroclaw went when they changed the MUX, I assume Opole and Historia etc have now done the same. What I am left with is a list of channels when I do a scan but next to all of them, even Polsat, is the euro symbol, and if I select the channel the receiver says "scramble channel" (not scrambled but scramble, don't know if that makes any difference, ale jaja).

If anybody has any experience with this, please post.

If your only contribution to this thread is a wisecrack - please don't bother, although granted the bump may prove useful.

Gone for ever. They will return once you say you know Polish.

Thanks for the bump and yes you are witty.

The channels are all back now, must have been an outage or someone at the transmitter plugged their toaster in to the wrong socket.

You see? Didn't I tell you? To prove you know Polish, you have just used this common Polish colloquial expression and all the channels are suddenly back again! Ale jaja!!!

Yes, I said it a few times as I stood angrily staring at the blank screen saying "No signal".

Or possibly my ale jaja was so loud and scary that the man who had unplugged the TVP transmitter so he could recharge his mobile phone woke up and plugged the TVP transmitter back in again.

So, congratulations to you! As this old Polish saying goes: all's well that ends well.

Can anyone tell me if TVP 1, TVP 2 and TVP Sport are free to air on DVB-T in Warsaw please?

Yes, they are free to watch in Poland, check more details (and available channels) here:

Just to add if you have a smart tv you can get these channels via TVP VOD, IPLA and WP Pilot apps for free, don't even need to be in Poland if you have a vpn set up
