You need to determine what is happening after 10 minutes. Something warming up? Something switching on or off? Something timing out?OK- got my BBc channels back- all with correct numbers.
BBC1 came on perfect picture and sound - 62% signal strength and 90% quality.
All other channels had same signal readings too.
Then- 10 mins later- bbc went off-- signal strength 57% and signal quality 0 %.
I thought about that Sam--but-the aerial is connected straight to the tv-via attenuator and freeview. Nothing else with any sort of 'time out' connected.
About 3 hours ago- I took the 'high faluting' !! fancy high gain aerial off and put on the old one out of my loft.
Wiped all channels and re-installed with attenuator wound down. Programms came back but with no bbc. so repeated the exersize with attenuator turned up.
Got all channels -no probs 'except one' !!. BBC channels were back on- but is BBC wales .
Left it on for last 3 hours- and nothing goes off like it did with big aerial.
My conclusion is- Sam got it right- regarding too much gain to freeview box--because as sam said- the signal strength was bouncing up and down on BBC channels.
maybe my next move is to keep re-programing until BBC proper comes back on ?. Also not plugging the aerial in until lower channels have been passed on re-prog?.
Also- maybe I just need a simple upgrade of aerial -- a sort of 'in between' aerial of my old simple one - new high gain one ?..
ps- I know this may seem a bit boring to people- but if any info gained on here helps someone- then it's all to the good .
