Analogue and digital signal strength

The strength of an analogue signal is no guide to the strength of a digital signal

The strength of an analogue signal is no guide to the strength
published on UK Free TV

Many people ask why they can receive an OK analogue picture, but need to upgrade their aerial to get Freeview, or sometimes get perfect Freeview reception when the analogue picture is very poor.

The digital signals are currently broadcast at low power (this will change as switchover happens) to prevent interference with the existing analogue signals. Thankfully most Freeview boxes can work with these weak signals. The following list shows the strength of the digital signal compared to the analogue for the 80 Freeview transmitters.

alan - absolutely not!

And I don't think you can get boxes to do analogue tuning.

Sounds like a swap with someone with a decent analogue TV would be best.

Do check that Cyprus TV is entirely compatible with UK. There can be variations in things like sound separation.

alan draper: Cyprus uses PAL-B (for VHF) and PAL G (for UHF).

The UK uses PAL-I.

A UK set will not have any sound if you use it for analogue reception in Cyprus, unless it the ability to change "region".

I live in the Darvel - 2% area.
I have two JVC LT32DE9BJ 32" Hd Ready Lcd Tv with Integrated Freeview. Recently both have stopped recording tv programmes when they are in standby mode. They will record if tv is actually switched on. This has only been happening over the last 3 or 4 months.
I have a Sagem box wired through one of these tv's and it records everything !!!
On checking my TV signal; strength 72% (as i installed a new aerial since last post)& quality 100%.
Anyone any ideas what is happening - TV's have no fault one has been for repair and sent back - no fault.
Most programs just do not record off the EPG.

will morton: Can you try doing this My Freeview box has no EPG, is blank on FIVE, ITV3, ITV4, ITV2+1, has no sound or the channel line up is wrong | - independent free digital TV advice to each device.

I'm a bit confused about a TV that you say is "recording".

WILLIAM MORTON: It is not usually possible to "record from a TV set", if you have a digital recorder, the tuner is in the recording device, not the TV.
