You are about 34 km from the Crystal Palace transmitter and the prediction is that you should get good and reliable reception of all the multiplexes available. There is a rise between you and the transmitter but that is unlikely to be the cause of your problems.
So it is likely that there is a poor connection in your aerial system. Check all the cables for any damage, check the aerial is pointi ng in the same direction, at a bearing of 68 degrees, as your neigh bours aerials. Then check for any poor connection by unplugging all the aerial plugs/sockets and refitting them (that is to remove any corrosion/oxidation from the contact surfaces) and ensure that the cable is fitted correctly and tightly in the coaxial plugs.
Then check that your TV is correctly tuned to the Crystal Palace signals on channels 23, 26, 30, 25, 22, 28, 55 and 56. The ARQB (called by some COM6) multiplex is on channel 28. Do that check using the manual tuning page of your TV (see the User Manual for how to access that) but DO NOT RETUNE unless any are tuned to the wrong channel. Use the channels listed above, taken from the Digital UK Coverage Checker for your location at Coverage Checker - Detailed View

Thanks MikeP for the response. All available channels were fine and nothing been added or removed, just seems a bit strange just COM6 channels are affected. Will go through your comments and see what the issue is.

Aerial system problems are well known by technical people to affect different frequncies differently and at different times. That is what's appears toi be happening with your system affecting the ARQB services.

Interesting, I had the same fault, traced it back to a Panasonic Freeview HD recorder, that was de-powered but still in circuit (aerial connected) It seems this box attenuated the ARQB service on Ch 28 the most, ARQA was still low but acceptable signal strength as were the others off Crystal Palace. Bypassing this box or returning power to the box fixed the problem!

The signal pass-through of your Panasonic HD recorder electrical requires power to send the signal from the input socket to the output socket - it is not a simple direct connection but has some electronics in between. That needs to be powered to allow it to perform the pass-through properly. Hence it was attenuating signals differentially but returned to normal as soon as the power was returned.

Just to update all the problem is now resolved. Would appear to be a connection issue in my setup. Many thanks to all who helped.

Would there be any reason I'm not receiving all available HD channels on my new television? I receive just BBC 1 and 2, ITV, Channel 4 and Channel 5.
Do I need a Freeview box?

Alan Granley:
Normally you need a Freeview HD equipped television or set top box. If your equipment is described as Freeview HD then it can receive the HD programmes providing you have a wideband aerial, changes to the transmission channels earlier this year meant that the older Group A aerials are unable to receive any of the HD channels provided on the COM7 and COM8 multiplexes. (An HD Ready television will not receive the HD transmissions as the description only applies to the screen capability.)
If you also give a full post code we can check the expected reception conditions at your location and advise accordingly.

Hi Mike, thank you for that.
I'm not prepared to give my post code publicly. Can I send it to you privately?
