Hi
I am at GU33 7AH. Before switchover we could only get BBC channels - Following switchover on the 14th we are unable to receive programmes on channel 62 (ITV3 etc on SDN).
There seems to be a weakness on 59 and 50 but they do come through.
62 shows signal strength at around 68% and quality fluctuating from 0 - 50% on my Humax box
Any thoughts and will this improve
Thanks Phil

Phil: C62 problems could be due to interference from a VCR or Sky box with the RF modulator set around C62/C63, or maybe an out of area transmission travelling further than normal due to the inversion effect during the current weather conditions. It is worth checking that cables and connectors are all in good order, and try repositioning aerial leads and any HDMI cables relative to the Freeview box. C50 is currently at 1kW, this will increase in power to 10kW on 25th April 2012. Later this year, in October, SDN will change frequency to C54 (and D3+4 to C56).This is for 4G clearance of C61/C62.

Hi KMJ
Thanks for the comments. I see that 62 is transmitted from Rowridge and Midhurst. Both transmit SDN. I have managed to pick up a programme guide for SDN channels on channel 62 using a manual tune. The programmes are numbered in the 800s suggesting the Midhurst signal is being blanked out by the Rowridge signal.I have checked video recorder RF output and all are set on numbers well away from 62. Tuning the analogue tuner I did find a few snowy analogue stations still transmitting so I suppose analogue interference is possible.

Hi, my postcode is GU32, aerial is on roof. Switchover was fine with access to all Freeview channels except the HD. Have tried manually tuning on 51, 52, 53, 54, 58 - no stations found. Strength 80%. Any thoughts on the HD? (GU32 ae)

Hi all, especially jb38.
We've waited for the final switchover at Midhurst and have now lost ALL freeview channels on our Humax8000T PVR. (All TV's OK and have great HD channels on our Samsung which, incidentally,is plugged into the Humax).
Have tried the set top aerial and see no channels (signal strength around 20/30% and 0% quality even when moving it around the house and pointing in all directions).
One question to anyone;
When manual tuning we have options which include MODE (set to auto but does have 8K option) GAURD (set to auto but has 1/4,1/8,1/16,1/32) NETWORK SEARCH (either disabled or enabled). We have tried various permutations but still no channels. Do these options show what could be our problem, what is it that has changed from the previous Freeview transmissions to the current transmissions which our HumaxPVR cannot handle. Any answers appreciated before we end up throwing it in the bin!
Thanks in advance.

Darren Ellis: Thanks for your latest report, as I was wondering what the situation would be like with your 8000T come complete switchover.
But regarding the Humax, you shouldn't really require to do anything, as if its set on auto it should detect the technicalities involved with the mode being transmitted and correspondingly adjust itself to suit, but the fact that its not strongly suggests that there is either a fault with the tuner, and in particular the 8k chip allegedly fitted, or that's its never been activated right from the start, as the only real thing that has changed at switchover is that all muxes are now operating on the 8k mode whereas before it was only the BBC mux, this being the start of your problem.
The other point is, that you have proven that feeding a reduced level of signal into the tuner via the set top aerial hasn't helped either, so the excessive signal level theory can now be eliminated.
I cannot really see any way out of your problem except possibly by tuner replacement, although "if" the tuner is still available as a spare part the whole exercise is liable to outweigh the value of the box, so much as I am a "never say die type" of engineer I feel that the word "discard" might be appropriate to this situation.

Some peculiarities down here in darkest Coldwaltham. Before switchover the DAB radio was atrocious, reception was bitty at best. Since the c/o the Dab has improved with around 60% of the channels available. we are still finding that Heathfield transmitter strength is overpowered the Midhurst transmitter, so after a factory reset it's a case of identifying the Midhurst channels that went to 800 on the television and do some juggling around with the channel menu. An annoyance as one oversight by the switchover people was a lack of station ident being broadcast, you have to wait for local news to come on in order to find out exactly what you are watching.

When will COM3,4&5 be transmitted at full power from Midhurst?

D Pritchard: ArqB is currently being transmitted at 1kW, this is planned to increase to 10kW on 25th April 2012. Digital UK show SDN and ArqA to be currently at 10kW, which is the planned "full power" for the COM muxes at the Midhurst transmitter
