I receive signal from the Sudbury Transmitter, Why do I have to re tune in November ? Also will the MUX for A, COM5 & COM6 increase ? Currently showing 'VERY LOW' on your charts and consequently signal/reception quality not consistent.
I live in Felixstowe.

jb38 : you may be interested in what has happened with my dad's Freeview 'gadget' after DSO Part 2 (at IP2 0QH) :
It now gets the 3 low power MUXes at strength < 50% and quality between 50 and 75% ; BBCA remains at 99% strength but <50% quality; but D3+4 on CH41 is totally absent! He told me this on the phone, but I didn't believe him so went round to check. It shows as 0% strength and quality BUT the 'meter' flickers all the time it is on that channel which makes me think it IS finding something. He therefore has no ITV/C4/C5 etc on the 'gadget'. His Freeview on DTV ; PVR and standard 'box' have all re-tuned happily and found all MUXes including D3+4, which is at full strength and quality.
I can only think, as per my original suspicion, that the signal is now too 'loud' for the gadget.
I am about to go away on holiday but will try some alterations to what he's got when I get back.
Everything at my place is working fine.

Transmitter engineering: I did an "initial scan" deleted all channels. Good signal but how do i get HD. No sign of it mentioned on using guide (epg), or listed as addition channel.
Tried bbc1,2,itv1 and others. Pressing "I" on some channels says hd is available.
tv is a panasonic TX-L32S20BA (full HD 1920 * 1080) Area Ip5 (Kesgrave), trasmitter Dudbury.

Dale: I've seen this Single frequency interference | ukfree.tv - independent free digital TV advice problem so many times, and it almost always caused by having an amplifier in the system.

Jim: The signals for SDN, ArqA and ArqB cannot be taken to full power until the final frequencies C56, C58 and C60- for the transmitter are taken out of use at the Tacolneston transmitter, where they are used at the moment.

Dale: The "non standard switchovers" tend to happen in certain international border coastal areas generally, but in this cause the non-PSB channel allocations being in use on the Tacolneston transmitter.
