 Using TV in different room to the receiver box - Dave
I want a TV in my bedroom, but don't want to buy a second receiver box or run a coax. Is it possible to buy something that transmits the picture and allows a remote to work the box from a different room?

You need this kind of thing:-

no idea if that one is any good, picture quality does vary drastically on these things.

I know you're in Sweden but got an OK one from Tesco years ago for £24 that worked. Apart from when the microwave was on.

I'd worry how leaky your microwave is/was if I was you.

I bought ours from LIDL for £29.99 about 4 years ago and set it up in the holiday house (only one UK TV signal at a time). The main TV is in the sitting room and the slave is in the kitchen behind a 2 foot thick stone wall. It's not happy pointing straight to the slave TV through the wall but somehow works OK when pointed to work though the door. Curious, as I can't imagine the signal going around a bend in an L shape.

Anyway, it works fine except when the microwave oven is on in the kitchen when the picture goes to anything in between wavy and blue screen.

Radio waves at these frequencies will reflect reasonably well off most hard surfaces, so it's reasonable that you'll get more signal at the receiver reflected via an open door than transmitted through stone, which will reflect most of the signal back in the general direction of the TV and use the rest to heat of the stone a little bit..

Microwave ovens operate at such high power that even properly screened ones can leak sufficient power to deafen sensitive receivers operating in the same frequency band e.g. wifi networks and video senders.

Our new Pansonic combi microwave (does excellent, crisp-skinned baked potatoes, BTW) leaks enough to interfere with my electronic scales, 4m away across the kitchen.

Now that's pretty impressive! I'm struggling to think how they've managed to design scales that sensitive to low level RF, either that or your microwave really is very RF leaky, which I very much doubt - you'd need a pretty big hole in it to leak the 2.4GHz RF.

I suspect the scales - Salter cheapies from 2005. I only noticed the interference because I like to weigh the flour for the bread machine while the water warms in the microwave.

More of a nuisance is when I try to follow a recipe I've found on the iPhone; unless I turn off the 3G signal the scales fluctuate wildly.

very poorly designed scales then.
