Thanks Briantist.
Yes its definitely 'single frequency interference' as those other channels on the list have gone as well.
Coming up is lawn mower and motorbike season which are usually random channel killers.

Just checked at see that the mux is on ch67, right at the end of the spec for the aerial
-and then transmitted on a low power-
So not much hope at all then till September?
ITV4 will not be missed as they been showing the same programmes for 7 years.

Re powers from Sandy Heath. Russ your comments support what I see, come spring 2012 we'll see who is right.
On another subject, wrong aspect ratio on BBC HD on Samsung TV. I have done some research and found the BBC are switching between 1080i and 1080p on BBC HD. This is causing Sony Bravia TVs to suffer audio drop out and seems to be making my Samsung switch to 4:3 when 1080p tx'd

there seams to be a reduction on the sandy heath transmitter over the last 2 to 3 weeks, and my digital signals are playing up really badly since the switch off.
how long is this going to last for
| link to this comment |
d shannon: A reduction? The signals are considerably stronger (they have gone from 20kW to 180kW).
If you are having problem you probably have overloaded your system.
If you have a booster or amplifier, remove it, this will clear any problems.

Dominic: As above, some people will be unable to receive ArqB until 14 Sept 2011.

Jack: The higher power signals will probably hold better against induction interference from 2 stroke engines, but better aerial positioning can also deal with this, as well as using satellite-grade coaxial cable to connect to the aerial.
Yes, you will probably have to wait for 14th September.

In the six mux lists of channels transmitted there is no mention of ESPN, SkySp1 or SkySp2 being transmitted. I can actually receive ESPN, why is it not in the lists? Could you also confirm if SkySp1/2 are being transmitted, but as BTVision suggest I possibly need a booster to pick them up.
These channels are not listed on the Waltham transmitter either and BTVision say I will receive them from there as the transmitter is closer.

JohnB: this site is about free tv, subscription channels are not shown. ESPN is on SDN, Sky Sports 1&2 are on ArQB (or Mux B pre-switchover).
