not quite.... I added in the aerial booster and THEN turned the gain of the distribution amp down
As I said I am fully aware of possible problems and effects of too much signal - but as it only appears to be affecting a couple of channels on one mux (COM7) I think we can discount that

david: So you added in an aerial booster..and then turned the amp gain down? So thats still boosting the signal....
Still, as you say, your fully aware of the problems of too much signal.

david: "Would the aerial ... now be unsuitable for Tacolneston I wonder?"Maybe not ideal for COM7 on UHF 31. See http://satcure.co.uk/tech….htm :"The DAT45 aerial has a maximum gain of around 16 dB ... However, this gain is concentrated in the upper part of the UHF band so this type of aerial is NOT suitable for ... channels at the low end below number 30 ... you might like to consider a different aerial."

david: COM7 will be around until 2020, it won't be closing next year. It will be moving to C55, with COM8 moving to C56 after the frequency changes take place on all transmitters that carry these muxes, until mid 2020.

The table above does not show COM7 or COM8 on C55 & C56.
No one answered my previous question as to whether any muxes will be changed to DVB-T2 next year to increase capacity and bring more HD channels.
Some h.264 channels are already being transmitted but they are all 544x576 anamorphic at pathetic 1MB/s avg, is this what we can expect for Freeview in the future?
Ofcom have already stated they are to lift the minimum bit-rates for the main channels.
I guess we will see more channels crammed in at stupid SVCD frame sizes with bit-rates worse than Youtube just so broadcasters can maximize ad-revenues.
It matters not how good your 4K TV's upscaler is, the picture quality is going to look a mess with a 544x576 1MB/s h.264 source

Christopher Webber: It has been widely publicised that COM7 and COM8 will be on C55 & C56 forming a single frequency network following the frequency changes at each transmitter that carries them. It is not shown in the table above because the end column shows frequency allocations following the 700MHz clearance at each transmitter, hence COM7 & COM8 not being shown post 700MHz clearance on any transmitter as they will close at completion of the 700MHz clearence in 2020.
There has been no announcement of any further multiplexes changing to DVB-T2 and it would be very unlikely that such a change would be made with as little as 1 years notice. I would speculate that 2020 would be the earliest any further multiplexes would change to DVB-T2 as that will be the point where the additional capacity provided by COM7 and COM8 will be lost.

Hi StevensOnin1,
Thanks for the explanation, the table is somewhat misleading as the date is 2018 but like you say it shows the mux allocation post 700mhz clearance.
If there are no changes to the basic 6 muxes post 2020 then that means Freeview viewers will see a huge drop in HD channels, with COM7 and COM8 disappearing we will loose BBC News HD, BBC4 HD, 4Seven HD (not concerned with C4+1HD, QVC HD, RT HD or Cbeebies HD) they are a waste of precious bandwidth already :)
There will be no capacity on BBCB for those channels in HD and that is shocking,
Looks like the whole DSO has been a huge con, imo as Freeview will essentially be not fit for purpose and people will be forced to get Sky or Virgin just to get HD :(
Looks like the DSO was just a huge con to get the TX's enabled for 4G & 5G at taxpayers expense.
I am seriously considering cancelling my TV license and just subscribing to Netflix :)

Christopher Webber: I didn't say there will never be a change to DVB-T2, I said that none had been announced yet. It is widely expected that it will happen eventually and that PSB channels will switch to HD only output. Both the government and BBC have said in the past that this is the plan long term (and switching BBCA/PSB1 to DVB-T2 will provide more than enough bandwidth for all BBC channels to be available in HD from every transmitter). No one will be forced to switch to Sky or Virgin. I'm not sure how DSO was a con when everyone is now able to receive far more channels than the 4 or 5 that were available with analogue and there wasn't even any suggestion of HD being available on Freeview when DSO was first announced. DSO was not undertaken at tax payers expense, it was paid for by the many millions of pounds that were raised when the 800MHz band was auctioned to the mobile networks (leaving a large surplus) and the many millions more that will be raised from the 700MHz auction will pay for the 700MHz clearance, including providing new aerials for those who need them. The date shown on the table appears to be based on when the frequency changes are due to take place at that transmitter, not the date the the frequency clearance program will be completed.

By the time Freeview finally gets plenty of HD content Netflix and other services will be offering 16K or 8K at minimum lol, even Youtubers are shooting in 8K and uploading in 4K (using Red cameras @ $35,000 each lol) - LinusTechTips being a prime example.
Long term there is no way Freeview will ever have the capacity to support 4K let alone 8K, this is why I think the DSO has been a con, now the 800 and 700mhz bands are being sold it just leaves the 600mhz band, even at QAM256, even with all 6 muxes transmitting at that rate, it only equates to 240MB/s maximum for all channels and radio services.
I think Freeview will eventually cease and all TV will be IPTV, probably within 20 years, it's inevitable, but during this time so many households had to upgrade aerials, TV's, set-top boxes, once to get DVB-T with so-called HD ready and again to get DVB-T2 so-called FullHD
To me it seems like it's been a con, but I'm a grumpy old git who dislikes parting with my hard-earned money !
