Transmitter engineering: Channels on COM 6 are pixelated/sound breaks but all other channels are OK just the ones on COM6. Any ideas?

Naseem Shafi:

Please provide a full post code so that we can examine the reception conditions and predictions for your loocation. As there are no other reports of this problem with the ARQB service then it is likely a problem with your equipment, so please check all the aerial cables and connections. If there are coaxial plugs/sockets then unplug those and refit them. That will clear any corrosion/oxidation from the contacts and often clears the problem.

Naseem Shafi:

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.

Mr Naseem Shafi:
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!
