Thanks whoever took the cup of tea to the Engineers to wake them up - must have missed the Signal Volume chappie.

CM24 8DL - Stansted. Rooftop aerial horizontal + amp- std coax in house. TV. DVD HDD recorder Panasonic DMR EX75 with digital tuner inbuilt & Sony VTXD800 which feeds TV. connections. Aerial path first to Panasonic and then looped through to Sony and then to TV. All retuned successfully. PROBLEM - Tuner sensitivity of Panasonic is less than Sony so it appears that on the Sony we are possibly overloading on the D3+4 mux so that ITV and ITV+1 (and possibly the others) are dropping out periodically. Otherwise all OK on other so far. Switching off masthead amp gives at all - no pass through. Should I try and attenuator on the aerial loop from the Panasonic to the Sony to dampen its enthusiasm? Thoughts appreciated.

Dear Optimist - I put a 'high ' on the when the digitial signals started and found it wasn't really needed - I had way too much (over deviating?) so I put an attenuator in and the improved - now they've upped the power looks like I might need to wind in some more attenuation.

There is a checklist about signals being too strong on the Freeview signals: too much of a good thing is bad for you | ukfree.tv - independent free digital TV advice page.

Hi. I have retuned my Goodmans GDB5 several times, including twice with the disconnected, but I am not picking up 28. My TV is picking up 28 fine, which suggests it's not an aerial problem. .

Colin Newman: If I may, I offer an observation about GDB2 and GDB3 models.

I came across this previously:

http://www.digitaluk.co.u….pdf

28 is the only service from with a negative offset.

If I were you, Google around as others may well have experienced the same problem.

Here's the initial information my scanner receives:

T 490000000 8MHz 2/3 NONE QAM64 8k 1/32 NONE # .
T 514000000 8MHz 2/3 NONE QAM64 8k 1/32 NONE # London .
T 545833330 8MHz 2/3 NONE QAM256 AUTO AUTO AUTO # London .
T 482000000 8MHz 3/4 NONE QAM64 8k 1/32 NONE # London .
T 506000000 8MHz 3/4 NONE QAM64 8k 1/32 NONE # London .
T 529833330 8MHz 3/4 NONE QAM64 8k 1/32 NONE # London .

It doesn't quite match the numbers given above. For example, ArqB seems to be on 529.8MHz instead of 530.0MHz, and if I force it to 530.0MHz instead then it gives me everything on 529.8MHz anyway so that every is listed twice.
