The bright green areas shown where the signal from this transmitter is strong, dark green areas are poorer signals. Those parts shown in yellow may have interference on the same frequency from other masts.

I wonder what difference 18 April will make. I mean, I haven't watched for years now (I was living in S until recently and the analogue went off there 2 years ago), but I was wondering if the final death knell for analogue will an increase in the of the digital signal...as in my message above I've managed to finally rid my viewing of the accursed boiling problem (remember when Deayton and Richard Wilson were selling digital on the basis that you don't get ghosting or fuzziness...they didn't mention you might get far more disruptive boiling instead did they?...), for now at least. Hopefully with the CP fully switched to digital we'll see the end of it altogether.

...another thing, digital uses far less pwoer than analogue did, therefore the BBC will on its fuel bills...does that mean a reduction in, or at least a freeze for now on, the licence fee?....

Yours, more in than expectation...

Martyn Smith: From the description of the fact that you have turned your away from where it used to face I suspect that your aerial is way OTT which is overloading your tuner.

Before the of was/is 20kW. Where line of sight to the is good, a small set-top aerial is likely to be sufficient.

I used a non-powered set-top aerial at 25 miles from before switchover when transmission power was only 10kW. This worked quite well. I have one of these Labgear aerials:

Set Top Aerial Labgear | eBay

The fact that is so low may have come about due to the signal level being way too high for what the TV can cope with. It's a bit like turning up your hifi to full blast and then amplifying it a bit more. The outcome is total distortion which could explain the poor signal quality in your case.

Dave Lindsay: Thank you for your reply of 4 April at 6.45pm. You are right the 14 extra are duplicates on 800+ Will they disappear on second date?

The HD channels were seriously breaking up during the day today. I wanted to record a couple of programmes for earlier this evening, but didn't risk HD. However, having come home and checked the HD channels they are now perfect. Does night-time make any difference.

I don't understand muxes or how to determine which channels programmes are on, other than channel 1 for BBC1, channel 2 for BBC2 etc !!!

Big Mart: Yes, they will disappear at the second .

I'm not too sure whether different times of day makes a great difference. Evidently you're on the margin for HD which, BTW, before switchover are on lower than definition channels and therefore have a smaller footprint of coverage.

After switchover all channels are on the same power.

The above shows channel Nos until 4th April, the what they will be from the 18th April. But does not tell us what they will be from 4th to 18th.
I have found that even though I re-tuned my PC based recorder, none of the progams in my timer list have been recorded since 3rd April, I suspect this is because several TV & radio now appear twice in my EPG.

I dont understand why they just didnt do switch on a single date. All this business of giving people time to get a set top box is stupid, as they have had years to do it allready.

As usual in the UK the majority have to be inconvieneced to accomodate the few( if any) who have not prepaired.

Anyone else having problems with a slingbox post April 4th? I have lost half of the BBC Mux (No BBC2/News etc but can get BBC1). If I change the country to Italy (or another random DVB-T country) the whole comes in but I lose my Freeview numbers..

Can someone please explain the status of the MUX PSB3/BBCB, please? (See above). Is it transmitting at "Very low" or "Maximum" ? I don't see how it could be transmitting at both.

BBC2 disappeared from my slingbox lineup in the last 24 hours after my buddy in the UK told me to retune using the input. I'm more than frustrated and I'm desperately seeking a solution.
