Chris Wood: Your TV (or set top box) has retuned and picked up BBC1 London from Crystal Palace before also finding BBC1 South from Hannington (Hannington uses higher frequencies than Crystal Palace and would therefore be found first on a retune if both are receivable). If you do a manual tune on UHF C39 from your TV's menu it should restore BBC1 South to position 1 on the program guide.

I can receive both Hannington and Crystal Palace signals (both approximately the same strength) and have the 2 aerials terminating into a diplexor with the Crystal Palace going into the "A" group input (channels 21-33) and Hannington going into the "E" group input (channels 39-68). Everything was fine until BBC4 HD recently moved frequency. Now BBC4 HD is breaking up due to very low signal. I realised that their new frequency is on channels 34 and 35 which is between the channel inputs of my diplexor and hence this is attenuating the signal on this frequency. I then replaced the diplexor with a Labgear 2 way splitter that is wide band and I can now get BBC4 HD again on full signal. Unfortunately this has created further problems as I can no longer get Freeview channels 7 and 8 (London Live and That's Hampshire) which I was getting with reasonable signal. There is a large overlap on the frequencies used by the Hannington and Crystal Palace stations. For example Crystal Palace uses channel 33 but Hannington uses channel 32 and also channel 29 I believe for That's Thames Valley. Any advice in resolving this problem would be appreciated

Roger Scott: This might be a tricky one to solve!. I can only assume that you were originally receiving BBC4HD from Crystal Palace COM7 (Ch.33) as COM7 on Hannington is on Ch.32 and your Hannington Aerial would be in the wrong diplexer input to get that signal without severe attenuation. BBC4HD moving to COM8 (Ch.35 Crystal Palace) or Ch.34 Hannington possibly won't have been helped by the slightly lower power used for COM8.
My understanding for Hannington is that the Local TV Mux aimed at Basingstoke is on Ch.51 whereas there is one aimed at Reading on Ch.29. I can again only assume you were getting the Basingstoke one. The Crystal Place local Mux is on Ch.29, and you got both of these because of your location and aerial directions.
Now that you are using a splitter instead of a diplexer, there could be some conflict with the Ch.29 muxes which stops you getting London Live, but there ought not be be an issue with That's Hampshire on the Ch.51 mux. However, Local muxes are on a much lower power compared to the main ones. Diplexers don't usually have much insertion loss, whereas a splitter can have quite a lot depending on type and this could reduce the signal strength sufficiently. There are types with low insertion loss which may not be what you have, but I would firstly try to see exactly what you can currently receive on each aerial plugged directly into the set without a diplexer or splitter to check you can get what you'd expect, you'll then have an idea whether the insertion loss from the splitter is the primary problem.

Roger Scott: Forgot to add, that if you are getting a significant signal on Ch.29 from your Hannington aerial (the mux aimed at Reading) then this will be a much more difficult issue to resolve at this time, also after March 21st this year COM7&8 at Crystal Palace move to Ch.55&56. These muxes at Hannington move to Ch.55&56 on April 18th. So it's possible that your current diplexer will give you a working solution after that date.

Roger Scott: OOOps, sorry, my last statement is incorrect as the Local Muxes are also moving channel.
Crystal Palace is moving from Ch.29 to Ch.35 on March 21st (with apparently some increase in power - not sure of detail), and Hannington is moving from Ch.51 to Ch.32 on April 18th and the other local Mux on Ch.29 is moving to Ch.34 on that date.
So a standard diplexer is not going to provide a solution, whereas a low loss splitter might.
Also with COMs 7&8 on Ch.55&56 from both transmitters after that date, though they are SFNs you hopefully won't have a problem, but you definitely shouldn't if your Crystal Palace aerial is a Group A aerial and so won't get Chs.55&56 with any decent strength.

Chris. Thank you very much for this information. It seems that I won't really know the outcome until these other frequency changes are done in the spring. For the moment I have refitted the diplexer so am back with the BBC4HD signal problem but I can use my Sky box to watch this channel. My Crystal Palace aerial is definitely an A group and the Hannington aerial is possibly a B group as in the anologue days Channel 5 on channel 66 always had a snowy picture. It would seem with the frequency changes ideally the aerials should be wide band. I image that there are similar frequency changes in other regions as well in preparation of loosing the 700 MHz band

Roger Scott:
Instead of using a diplexer feeding two aerials into one TV, you may well do better to have a coaxial switch that is fed by both aerials. You can then switch between Hannington and Crystal Palace without getting any problems of interference between the signals. Plus there would be less signal loss.
When I live in Swindon, I used one so I could get both Mendip and Oxford signals and watch Central South as well as BBC West. It worked very well for me so it should be ideal for you, certainly better than using a diplexer with its losses and risk of serious interference on some multiplexes that share the same channel.

MikeP. Thanks for that suggestion which does make sense. The only problem I have is that the aerial feeds go into the loft where the diplexer is and from there I have one coax feeding down to the TV. Obviously it's not practical to go into the loft every time I want to change regions so I will need to fit an additional coax from the loft to the TV so that I can fit the change over switch by the TV

Obviously it's not practical to go into the loft every time I want to change regions so I would need to run another coax from the loft to the TV so that the change over switch is near the tv

Help! I am in the RG31 post code area and receive signal from Hannington transmitter. Since the beginning of February I have been having problems with low signal quality. I have been monitoring this on my TV diagnostics facility now for 10 days. I noticed that the problem started at around 16:30 each day, including Saturday and Sunday. Before 16:30 signal quality is reliably at 100%. After 16:30, signal quality plummets to below 10% and regularly below 7%. This situation lasts for 70-75 minutes, when the signal quality becomes 100% again. Note that the signal strength does not drop, at least until the low signal quality causes 'no signal'
It appears that something is switched on at 16:30 and interferes with the Hannington signal. 75 minutes later it is switched off and the interference disappears.
What can I do to identify exactly what is going? I do not believe it is 'induction' interference from other appliances, as I am quite familiar with that.
