Anyone else having problems on Taccy ........ all the channels on COM 4 & COM 5 are erroring & pixellating and the TV signal meter shows a slightly lower signal strength (7/10 to 8/10 rather than our normal 8/10 to 9/10 on these).
All the other channels are OK with zero reported errors and a sig strength of 9/10 to 10/10 which is normal.....all the HD channels are perfectly OK

Hi, appreciate this is a a bit late into the discussion but why can we no longer receive Planet Rock and Absolute 80's here in mid Suffolk ?
I have re-scanned the car DAB and the coverage maps suggest we can....

Not a TV issue but has anyone else noticed a downgrade in reception on DAB - particularly car DAB ??

Tonight again we have intermittently lost the HD channels......sig strength around 40-50% (normally 90) quality also down. IP23 8LP

any problems with channel 4+1 ?
tonight (24th Jul) it has been intermittently showing no signal
all other stations seem to be OK ...I don't understand how that can be if they are all on the same mux.

OK, thanks.
my setup is as follows : Televes DAT45, (NECESSARY before DTTV but in bypass since) on roof feeding into Antiference 4 way distribution amp feeding 3 rooms.
I checked the signal levels and quality on all the TV's and found them to be 9 and 10 respectively apart from the chan 4+1, so today I re-connected the power unit to the aerial and turned the gain on the distribution amp right down to min (don't panic - I AM aware of the issues regarding signal overload) and the signal has come up to 10 along with the quality except for chan 4+1HD which is way better but only about 7/10 signal and 60% quality - again I am aware that quality and BER are more important than signal alone.
Would the aerial group now be un-suitable for Tacolneston I wonder?

ps...off topic but I am not receiving email updates when people reply......

...oh, and I am using high quality double screened + copper foil RG6 cable and high quality full brass plugs with soldered pins throughout - I replaced the whole lot a few years ago :)

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

.......or I might like to wait until com7 disappears next year
