Mark Lewis: How is reception of C33 from Sutton Coldfield?

Mark Lewis: If you are using manual tuning and there is an option for DVB-T or DVB-T2, then select the latter for this and other HD muxes.

heather brown: Although having posted your query earlier on today, should you still be experiencing the problem then you should check out your installation / aerial system as the Sandy transmitter is operating as normal.

Everything OK compared to last week, but HD channels now breaking up. Only just started to happen. Was OK prior to other HD channels coming on board. Is there any link?

I can't receive channels on frequency 21 from sandy heath. CB1 9YE.
I have received it in the past from the same aerial (loft which I lack access to), but because I normally use cable TV, I can't pin down what has changed when.
All other channels have excellent reception - BBC/ITV/C4 in particular have 100% signal and quality.
Interestingly when I manually scan on 21, it picks up strength (around 90-100%), but quality is always 0 and no channels are found.
I bought a variable attenuator in case the signal is too strong, it it does reduce signal strength (including manual scan on 21), but what ever I set it at it never finds channels.
My parents less than half a mile away get the HD channels no problem. I even tried the same HD box to exclude equipment.
Before I hire an aerial expert to install an external wideband, any ideas?

You don't give any idea where you are located so we have a problem trying to work out what the cause of yo9ur problem might be. A post code , or one of a nearby shop, would help as would a model number of your equipment.
Indoor aerials, as opposed to loft aerials, arew notorious for poor reception of some signals but not others. Just moving the aerial to another location in the room can improve some signals but other may deteriorate.
Only an outdoor aerial on the roof, or possibly in the loft if the location is suitable, is good enough to give reasonable reliable reception. Room aerials are rarely good enough unless you are very,very close to the transmitter aerial.
