Does your tester not have some kind of "auto-off" function you can enable?

Stereo drift is another problem with DAB broadcasts so much so that genuine live stereo broadcasts are no longer transmitted. The stereo we hear at our end is usually the result of software processing which takes time which results in a considerable delay. If you listen to a genuinely live stereo broadcast on DAB it has the habit of momentarily going mono at regular intervals, it has I believe something to do with the way bit rates are fed from the the mics to the AD converters on the DAB transmitters.First I've heard of 'stereo drift'.... can you give any link to an original source about it?
Why is this different from a loudspeaker emitting two different frequencies at the same time.I like the way Bored Chemist cuts straight to the point :-)
Can't an electron do that?
How can electrons be stripped off something without changing the structure on an atomic scale? Is hair still "hair" after combing it?
Human cells have 23 pairs of chromosomes (22 pairs of autosomes and one pair of sex chromosomes), giving a total of 46 per cell.
You also test putting a phone inside an all-metal biscuit-tin with a metal lid. Usually you'll find the phone still works - again because the seal around the lid is not a good quality continuous electrical contact so RF potential differences can still arise and the signals escape...
If you were to scrape off all the paint, and solder the lid to the tin all round (and solder across any original seams that weren't electrically sound) then it should fully block the signals.
That should block the electric component, but it might not block the magnetic component. It shouldn't really be necessary to solder the thing shut either. There can be plenty of gaps just as long as they are not too large in relation to the wavelength.
If my $8 a month T-mobile phone had any coverage where I live, I would try the experiment.
Why is only half of the roof covered with snow? Do you have some kind of unheated attic in part of the house, and upper level living quarters in the other part?
You do have a lot of window surface area. Single or double paned? Brick isn't noted to be a good insulator.
