Any idea why this transmitter has changed channels to D41, D44 and D47 post switchover?
It used to broadcast on 48,50,52 and 56 so people now require a new aerial if they had a C/D before.
In addition, it is now co channel with Sudbury. I am new to the area but have already seen a few aerials pointing there (probably years old, put up before Greenwich opened).
The owners must of had no digital signal then suddenly it appeared last year when Sudbury powered up, then went again this year when Greenwich switched and the 2 signals knocked each other out...

brian manley: Some may need a different aerial but some will likely get away with the C/D one (or not notice).

In answer to your question, I should imagine it's to fit in with other transmitters.

This page might be useful:

C21 (474.0MHz) before switchover | ukfree.tv - 10 years of independent, free digital TV advice


However, reception of all channels from Crystal Palace might be possible at your location as the Digital UK predictor suggests and Streetview shows aerials pointing in that direction.

brian manley: One thing that is probably a factor in Greenwich not being given C/D channels post switchover is the ring-fencing of 61 to 68 to be sold off to the 4G mobile operators. Thus, useable C/D is now smaller than it was, in much the same fashion as useable A is now smaller due to ring-fencing of 31 to 34 (or 31 to 37 if you count 35 and 37, previously channel 5 only and 36, previously silent).

brian manley: I have drawn up the following list of transmitters that probably overlap with Greenwich to some degree:

48H Kensal Town
49H Alexandra Palace
50V Lea Bridge
52H Kensal Town
53V Woolwich
54H Alexandra Palace
55V Lea Bridge
56H Kensal Town
57V Woolwich
58H Alexandra Palace
59V Lea Bridge
60V Woolwich

The others seem definately likely, but I included Lea Bridge as it was the only other one that fitted in. It is definately a "maybe" as it's only 2W and not directed towards Greenwich. The only thing we do know is that it wasn't co-channel with Greenwich pre-DSO and isn't co-channel now.
