Thank You very much

Clacton is now up on mb21 complete with UHF panels.

Took my TV to Colchester today.
The signal was not watch able when the car was moving at high speed.
But the Clacton signal managed to get past Weeley before it died so would probably go much further on a TV Aerial I wonder if it may even be received in Colchester or Felixstowe on A High Gain Aerial?

Sudbury was working in most parts around Colchester town when car was still.

Looks like they've reduced the power of the muxes on 50 and 54 again, hopefully this will only be temporary and all will be well again after the 20th.

Is anybody else having problems with them?

JF

Just checked and you're right. Both 50 & 54 have dropped by 3dB from what they were yesterday. 54 is back to what it was, but 50 is still 4dB up on what it was on Tuesday. However I can see a 2dB or so droop on Ch 50 from LF to HF end of the signal, which is not on any of the other muxes from Sudbury. Ch39 is still 3dB up, but that is quite loud anyway.

Since BBC2 switch off & the need to retune I keep getting duplicate channels on my Topfield 5800 It has caused me all kinds of trouble. Only 1 of the duplicates of each channel actually work and I have to delete the other.

Is this going to be a common problem with retuning when the power gets increased?

Have you tried using the FastScanGUI and Channel Organiser TAPs to help with your retuning issues?

No, heard about it on the Toppy forum. Never had this problem as such before. The box has always searched for new channels (and exsisting ones I assume) with no problem other than buggering up the TAPS channel identification positions which is soon solved.

Will this be a neccessary TAP/s now?

Necessary for those struggling to avoid getting channels from more than on transmitter which is more likely as more regions become DSO and the power output is upped. Unless you want to tune in each MUX manually.

Although it's no longer a problem for me since I upgraded to a Human HDR FOX T2, I have the same thing happen on the 5800.

It seems that a channel retune does not delete the channels that were there before, therefore the channels from the old mux are left in place even though they no longer have a signal.

I guess the only way around it is a factory reset before the retune so the entire channel list and all settings are reset.

... and they're back again - if the signal strength remains constant over the weekend, then it's almost definitely just a temporary thing while work/testing is being carried out.

JF

Not even a factory reset did the job it still finds some duplicate channels. Maybe the power for what ever reason has not been switched off yet?

When I got home from work today I had time to check the other Freeview equipment that we have in our house so that I could see if the channels that are on mux 2 were working as they should since the we had the 1 stage of the DSO last Wednesday 6 July 2011 when BBC 2 analouge was switched off from the Sudbury transmitter.

The channels that are on mux 2 are as followes.

3 ITV1
4 Channel 4
5 Channel 5
6 ITV2
13 Channel 4+1
14 More 4
28 E4
33 ITV1+1

And this is the Freeview equipment that we have in our house.

Kictchen
26inch Sharp Aquos LCD TV with built in SD Freeview

Living Room
Panasonic DMR-XW380 Freeview+HD recorder

Samsung 50inch LED TV with built in SD Freeview

Spare Room
22inch Toshiba LCD TV With built in SD Freeview Model No. 22AV615DB


2nd Spare Room
Samsung LCD TV with built in SD Freeview model no. 933HD. (Not sure what the screen size is but it is either 19 or 22 inch).

A few years ago my mum and dad had there loft converted in to to rooms and one of them is there bedroo and in there they have a Humax PVR9300T (320GB) and an LG 42inch LCD TV with built in SD Freeview.

The channels that are on mux 2 work perfectly as they should on all of the Freeview Equipment that I have listed above that we have in our house.

It is just in my bedroom on my Humax HDR-Fox T2 (500GB) and my Hitachi 42inch LCD TV with built in SD Freeview that the channels that are on mux 2 break up with lots of pixelation.

The Signal for ITV1 on my Humax HDR-Fox T2 is 21% with quality 100%

So please can anyone help? Why am I the only one in our house having problemes with the channels that are on mux 2?

And will mux 2 work as they should on my Humax HDR-Fox T2 (500GB) in my bedroom when we have the 2nd stage of DSO on 20th July?

Thank you for the kind help in advance TV King.

Picking up duplicate channels is not unknown in the digital age when you have a choice of more than one transmitter (even if you don't know you have a choice).

I pick up a second TX even though my aerial points about 150 degrees in a different direction.

Because my main reception is a relay TX with only the PSB muxes I actually partially tune to the second TX to get the COM muxes - weak signal but usually watchable.

I start a factory reset to clear all channels but cancel it before auto tuning begins. I then manually tune to the channels I want.

I was wrong about the signal strength and quality of ITV1 on my Humax HDR-Fox T2 yesterday so here is the correct signal detection infomation from my Humax HDR-Fox T2 (500GB).

BBC One

Channel 44
Ch44, 658000KHz, 8MHz, 8K, 1/32
Strength 61%
Quality 100%

ITV1

Channel 56
Ch56, 754000KHz, 8MHz, 2K, 1/32
Strength 23%
Quality 30% but keeps flickering between 30%, 40. & 20%

The information for ITV1 is the same for all the channels that are on mux 2.

Pick TV

Channel 54
Ch54, 738000KHz, 8 MHz, 2K, 1/32

ITV4

Channel 50
Ch50, 706000KHz, 8MHz, 2K 1/32

Challenge

Channel 49
Ch49, 698000KHz, 8MHz, 2K, 1/32
Strength 42%
Quality 100%

All the channel on amy Humax HDR-Fox T2 (500GB) work perfectly as they should.

The only channels that braek up with lots of pixelation are the on mux 2.

I hope that this is fixed when we have the 2 stage of the DSO on the 20th July 2011.

On all the other Freeview equipment that we have in our house which I listed yesterday all the channels including those that are on mux 2 work as they should with and do not braek up with lots of pixelation.

And on the Sony VTX-D800U box that I gave to my local Tesco were I work so that we can use it in our staff caff has every channel working perfectly as they should even the channels that are on mux 2 with no braek up or pixelation.

Did you try tuning UHF channel 68 ? Mux2 is on two UHF channels 56 and 68 (ch68 may outside your aerial group, ch 56 is just above group B)

PSB-2 /MUX2 and PSB-3 /HD mux will surely be OK from July 20.

Lars

I have just done a manual tune for channel 68 and here is the signal detection information from my Humax HDR-Fox T2 (500GB).

ITV1

Ch68, 85000KHz, 8MHz, 2K, 1/32
Strength 20%
Quality 100%

This is the same for all the channels that are on mux 2 using channel 68 insted of channel 56.

When I did a manual tune for channel 68 I did not know what frequency I have to go for so I just left is as 85000KHz which was already there when the manual tune page on the Humax HDR-Fox T2 came up.

Channel 68

Seems much better to me - a weak signal, but little noise and Quality 100%

The signal and signal quality is always the same for all channels within any DVB-T mux - and also for DVB-T2 muxes as used in the UK.

Lars

PS! Channel 68 is 846-854 MHz - or 850 MHz +- 4 MHz

I see the problem now with my duplicate channels. CH39 is still broadcasting and the programs that remain on 39 are also on the new BBC-A CH44!

Deleting them tho' from the Toppy List menu doesn't satisfy the "Mystuff" tap I am using & consequently it often does not work & causes the 5800 not to function properly

I guess I'll have to try a new "tap". Hopefully this will be cured in 2 weeks time and at the same time a sad loss of signal to my analogue tv

Are you rebooting after you manually delete channels. Until you do MyStuff won't recognise what has happened and will be confused.

I have come back upstairs now after watching the Formula 1 British Grand Prix on BBC One HD on my dads Sky HD 1TB PVR and all the channels on mux 2 have no signal.

This is using channel 68 instead of 56.

When I go to ITV1 which on LCN 3 my Humax HDR-Fox T2 (500GB) come up with the message saying the following.

! The receiver is not receiving a signal or the signal is to week.

This is followed by ! No programmes are currently being broadcast on this Channel.

So I will ones my Humax HDR-Fox T2 has finished recording the Formula 1: British Grand Prix on BBC One on LCN1 and the The British Grand Prix: Forum on LCN 301 do an automatic retune and get mux 2 back on channel 56 and then I will just have to hope that when we have the 2nd stage of the DSO on the 20th July that all the channels that are on mux 2 work as they should with no break up or pixelation.

Several times. I've just unplugged it and it still comes up with the same message about duplicate channels or LCN's. Mystuff does not work at all now for EPG usage.

I've noticed there are 4 "adult section" channels divided into 2 different muxes. I don't know why there are 2 on each mux on different channel numbers. I've no idea if they are different or not, not the sort of thing I'd watch Anyhow I deleted the "duplicates" but still no joy.

You really do need to start from scratch with your channel tuning by using FastScanGUI to limit the scan to your local preferred transmitter and then use Channel Organiser to tidy up the channels by getting rid of the shopping, adult and pay channels.

I still measure them at the lower value, and my TV confirms that, as I get a really high error rate on both.

I'll measure them all again on 19th & then again on 20th to see what COM mux changes there are then.

Did a retune this morning on my Sony Bravia TV, all the duplicate channels on Channel 39 now appear in the 800's and of course the Mux on CH 44 is now 100% signal and quality. Although reception was 95% before so no change in quality but maybe a more robust signal during the tropo lifts.

No sign of any stations from the Clacton repeater on my TV, they were detected during the scan but Ignored on the EPG.

Although I am only 1.5 miles from the TX in valley road, the signal is only 73% on my high gain Sudbury facing antenna, but may be useful for a set top antenna.
