For the last 2 weeks my reception has been atrocious. I cannot watch any channels as they keep breaking up all time. I have reset time and time again with no change
I keep getting 'your signal is weak' come up on the television.
Is there a problem at your end?
My address is Bunkers Hill, Wisbech St Mary Cambs PE13 4AQ
Thank you

Terry Tibbs : There are no faults showing for the Sandy Heath transmitter (this website is independent and has no connection with the transmitter company or any broadcaster). Have you checked for any loose or damaged cables or connections behind your TV? Retuning will not fix a problem with weak signal and often makes it worse, as you are just deleting all of your correctly tuned channels and searching for them again.

Terry Tibbs:

It is possible that your "previous" reception difficulties may have been as a result of "interference" from other transmitters (including continental) due to the high pressure weather system(s) that we've had of late, but that should have cleared up by now. If you are still having problems you should do as suggested by StevensOnln1.
If that doesn't resolve the problem you may need to check your aerial and downlead, including making sure the aerial has not moved in the high winds.

I have a Desktop PC fitted with twin channel freeview card. and a Hauppauge WinTV v8 program. I have carried out several re-tunes and am missing a couple of channels, which I thought were on 722 MHz frequency. Investigation has shown that 722 MHz is no longer used and is replaced by 594MHz.
however, as mentioned, several scans (retunes) has not found 594 MHz
(The others I'm interested in are ok ie 498, 522, 690 & 714)
What could be the answer ??//
Regards Brian

Brian: I'm not sure as I have version 8.5 installed, and I'm in London where there have been fewer changes for 700MHz clearance.

So, which you pick DVB-T2 and UK in the tuner, don't pick your transmitter, stay on the genertic one. The 17 Jul 2018 chnages moved ArqA from the old C52 to C36.

Brian. If you have a loft aerial it can be quite sensitive to where it is positioned in the loft as it is affected by water tanks wiring and thickness of walls and roofs . The theoretical best direction can be disturbed too . Its quite possible that some channels are affected more than others . To add to your problem TV cards in PCs can be affected by interference from the PC . Again only certain channels may be affected.

Following a day when my tv suffered a load of weak/no signal messages on all channels (from Sandy Heath Transmitter) I now have all channels back with the exception of channels 55 and 56 (multiplex com 7 & 8. Therefore unable to receive BBC 4HD and BBC News HD plus other lesser used broadcasters.
Has Sandy Heath now stopped transmitting these channels and when will I be able to receive the missing TV stations, Note I've checked all connections, re tuned etc.

david mitchell: Digital UK show COM7 & COM8 as being available from Sandy Heath until at least 2020. Retuning was a bad idea as you've now deleted the tuning data for these multiplexes which were previously tuned correctly. If you've had a recent issue with weak signal then you may well have a fault somewhere in your aerial system, with COM7 & COM8 being the worst affected due to them being broadcast at much lower power. If you provide a full postcode we can see the predicted signal strength at your location, which may help someone offer further advice.
