Didital/analogue transmitters

  jack 09:40 30 Oct 2007

a friend has long time trouble getting a decent digital reception because an adjacent office block with all sorts of antenna on the roof in in the line of sight to his local transmitter[Crystal Palace].
The local TV engineer visiited him and rigged him up so that analogue continues from Crystal P but another Ariel for digital digital is directed to Blue Bell hill.
The result is a horrendous lash up of aerial inputs and 'box' connections.
Which means now that although he can watch digital, it seems as if he cannot record to his PVR.
I am going over to day to see if I can make sense of it.
As far as I am concerned the aerial input should be a simple series line starting at the digi box and looping in and out of other 'boxes' ending up at the TV.
I think to clean him up- a decision will have to be make Bluebell hill or Crystal Palace.
So my question is is Bluebell hill digital only?
or is it combined digital or analogue?
If the former would it be politic to advise go all digital and forget analogue?

As a Freeview set top box merely converts digital transmissions back to analogue (otherwise you wouldn't be able to watch programmes) and all the five terrestial channels are available digitally, it makes sense to only use the digital signal.

Your assumption that the aerial input is a simple series of connections is correct, providing that the PVR has an RF loop through.

I'm able to record Freeview programmes on a VCR (using the L1 or L2 VCR channel) in this way.

Bluebell Hill does both.(at the moment!)but you may find the channels are not the same.

Thank you both.
This measn then I assume that to get analogue via Blue Bell Hill it would be a simple matter of resetting TV/VCR/PVR, - is that correct?
