Barry Hardwick:

Either you have a problem with yiur aerial system of it is some form of local interference.

Check all your aerial cables and connections. Unplug all coiaxial connections and refit them. Then check what signal strengths you are getting but DO NOT RETUNE.

Barry Hardwick:

As MikeP says check/refit all your connections - a bit of oxidation on them can affect performance. After, if all your signal levels on each mux is what you normally get, I wouldn't worry too much unless it's happening on a regular basis and there is a clear pattern to when it's occurring.

Sometimes there are brief unexpected interruptions to signals which could be down to something local rather than at the transmitter, also important to distinguish between loss of the transmitted signal (no carrier) and just loss of the data feed to the multiplexes. With the former your set will normally tell you there is no signal.

28th June 2019 we lost signal at around 2315hrs. HD and SD were too weak.
I had a quick check of connection security and all was good. The next morning I had SD with some freezing, but not very often. By the evening of 29th at around 2100hrs I decided d to try my TV again and everything worked.
Was there a problem with the transmitter. I live in Wisbech and believe the aerial is pointing to Sandy Heath.

There was no problemn reported. So it was likely to either be the hot weather or esle a poor connection in yoyur aerial system.

The channel list for the Sandy Heath transmitter is not correct - it doesn't take account of recent lineup changes.

David Gurr:

As has been mentioned many times, unfortunately the site owner has not had the time to correct all the information on all the transmitter pages.
For the UHF channel allocations for each mux, you are best looking at Coverage Checker - Detailed View or by putting your postcode into Digital UK - Coverage checker you can get your predicted reception for your location Coverage Checker - Detailed View

For up-to-date channel listing for each multiplex, this is usually the best place Digital UK | Channel listings

All Using Sandy Heath:
Note that this week beginning 1st July, there is planned engineering with the possible effect of a weak signal.

Have lost channels 48 & 51, signal strength is pulsing, signal quality is zero. i have completely cleared tuning & re tuned but still no result. This has only happened since the very hot Wednesday earlier. Any suggestions

Mr Derek Bampkin:

Put your postcode into Digital UK - Coverage checker to see predicted reception at your location. If it is good for the ArqB and SDN multiplexes you mention, then as you mentioned the weather it could be the recent propagation conditions. Is reception now OK?
Propagation is predicted to increase again next week, so there could be further problems.

However, the heat may have also caused connection issues with your system, so do check that all coax plugs and sockets are clean and properly connected. By unpluging them, inspecting and replugging - this will help remove any oxidation that may be present that could cause connection issues. Does your set get the HD channels - was reception of COMs 7&8 (C55&56) OK? Also check that your aerial is still where it should be and pointing in the correct direction and the coax is connected and secure - you may need to get someone to check all of that if you continue to have problems. (I'm assuming your TV set is OK!).
