JB, when I press channel one, it says '1,' but is blank.
I am also puzzled by the fact that I am currently not getting pixellation, or something similar, ie a few small 'boxes' briefly dotting the screen now and then on the two strongest muxes, ITV and BBC. If you recall it was suggested this paterning could be the effect of too large a signal since erecting an almighty aerial, at height, with 28 db booster, to pull in the naff mux on c60

JB,
if I was using the Icecrypt box this would be useful, but I am using the pvr, Tvonics which does not have signal strength/quality bars, just sig qual which always says 'very good,' and sig level where the bar is always solid green.
Would you have any idea why periodically I lose these channels on the tuner? I switch the box off at the mains at night, but only the BBC channels, and occasionally the ITV channels disappear.

DTR 2250, JB.
I don't believe it shows the stations it is finding. It does have manual tuning. Progress bar during the scan. I disconnect aerial till nearly half way through to stop it logging onto channels from local relay, 23 and 28.
Thanks

JB,
thank you very much, will try this.
Sorry to be thick, but just wondering what we are proving here. Are you suggesting I might have actually lost the signal when I turn on to a blank screen? It does not say 'no signal.'
I will tune it to channels 41 and 44, only as you say, although what gets me is that these strongest channels are the ones that disappear.
[I know which are the strongest channels thanks to Icecrypt box.]

Please does anyone know why when I use a digibox with crt 12 inch screen tvs I get a buzz on the sound, but not with larger sets?

JB,
You are a marvel.
Yes, connected by scart to small set, buzz does change pitch according to brightness, but only marginally. Have another small set, ancient Fergusson without remote facility connected by aerial socket to Icecrypt, no problem.
I think you may be barking up the right tree re too much signal on BBC/ITV. I have a whopping homemade aerial and booster to be able at last to pull in the naff mux on c60. Fortunately I also have a 'homemade' booster, it is one of those behind the set ones. I have split it, with the gubbins on the mast, powered by a cable, to the transformer in the attic. I will remove the transformer and replace with 6 volts, as I found during testing I could reduce the gain that way. What a palaver over a rotten mux on c60! If I lose c60 doing this, I will swear!
I will also do your experiment.

JB, just to clarify.
Only my tvonics is on Sudbury. It is not overstretching itself with channels. I only connect the aerial when it looks close to channel 41, a trick difficult to achieve. If I do not do this, it logs onto the local Aldeburgh channels.
All small sets are on Aldeburgh.
Are you saying that if the BBC signal from Sudbury peaks too high it can cause the picture to vanish...and not be restored without a retune?

Thank you, JB, I will do your tests.
Did you have any conclusions re the sound buzz with small tvs/ brightness etc?

Dave, Nick has another problem. He goes away a few days, returns and finds his box has lost all the BBC channels but none of the others and has to retune. Please, any ideas?
