Different TV's different stations
 

why do different TV's have channels such as PICK on different "number stations" PICK on one TV and BT box is 34 on another TV it is 11, why?

No idea, but I am absolutely sick of digital TV full stop. I don't know how many times I have had to try and retune, not always successfully, and at least with Analogue I never lost the station due to "bad or no Signal", which I now do, whilst a cheaper set in the kitchen carries on regardless! Also, why when they move a station to another number do they never fill the original with another?

Rant over.

Hi Ian,

After having a conversation with Freeview's helpline about this I believe that the numbers are arbitrary. The TV tuner receives a group of stations on a single "multiplex" which roughly translates as a "channel" under the old analogue transmission system. The TV then separates the "multiplex" signal to give you the individual stations.

I have no idea how satellite and cable works or services delivered via a telephone line. :o

If you're referring to Freeview Malcolm it's because frequencies are being released for use by the 5G mobile phone service. Some "+1" and even some HD stations have disappeared permanently.

Simon,
thanks but why does one tv put Pick on 11 and another tv puts it on 34?
Signal is coming from an aerial not a satellite dish or cable

According to the aerial installer I had a couple of weeks ago,this has something to do with the transmitter, as well as the technology built into the tv.

Due to the TVs I have in the house, it was better to focus on a particular transmitter (I can receive from 3 different transmitters).

Our oldest tv would not be able to receive the HD transmissions from the one we have focused on, but the more used tvs can.

If we focused on a different transmitter it would display as a different number on the tv.

If you're watching on Freeview via an aerial, it should be on channel 34 https://www.freeview.co.uk/get-freev.../channels/pick, though I believe it was on 11 'till recently. Have you tried a re-tune on the TV that's showing it on 11 (11 on Freeview should now be Sky Arts now I think)?

oh ok. I think I did a retune and it made no difference and yes, Sky Arts is on the channel I thought pick was on. May be I retuned the wrong TV

Hello Mate,

Have you noticed it does the same with digital radio?

years ago when technology was not so good as it is now the recievers had a much bigger bandwidth...i.e. it would pick up the station or signal if it drifted abit, now a days the transmitters and recievers are so precise the bandwidth doesnt need to be wide and so when the signal drifts or becomes poor for any reason it can nolonger be detected.

fm and dab,digital radio has a shorter range from the transmitter as well as digital tv signals, try driving up to Inverness along the A9 to see how it works. When AM signals were on the go you could listen the whole journey, now, about 60-70% only.

I used to live way out in the highlands and tv signals were relayed using our own aerial system.... in came digital, out went our tv.

thats what they call improvements. :}

Several TV's here, but only one big screen modern Smart set. The rest have a restricted number of channels because of age. The Smart had an issue where it was constantly suggesting new channels had been found, so it needed a retune.

As one of the high spots, I receive from three regional transmitters, so the set during the retune would want me to tell it which region I was in. I eventually worked out, that I needed to fit an attenuator, so it would see fewer transmitters and concentrate on my main local one. It seemed as reception improved of more distant regions, at certain times of day, it would trigger the TV to request that I retune it.

The attenuator (a variable type) has mostly fixed the issue.

Don't forget to retune today as some channels have moved 😎
