Entirely agree. I just got fed up being told that "nothing" can pass through mountains and that neutrinos need a hole drilled through the rock. Can be educational, a little thread drift.

cstreat,
Assuming you'r still reading this thread.... I've been using a cheap pair of NTL radios I bought for about 50quid maybe 7 years ago from Dixons. They still work fine, despite having been subject to a level of abuse far higher thany they were designed for. They're frequently cold, wet, both, and move between hot and cold envts and vice versa.
Whilst I'll be taking a cheap nokia for emergency cover in my backpack, i won't be taking my 400gbp smartphone out on the hill...
Anyone who thinks you 'look like a twerp' because you use some kit, IMHO, is not be reasonable (and I'm being polite).
The usefulness of radios increases exponentially with group size, and the number of times I've re-grouped a group quickly and easily (and at zero cost), has more than covered the purchase cost.
Cross-talk from other groups can be an issue, but has never been insurmountable (provided you have one of the sets with the sub-channels, but anything other than the cheapest PMR's will have these now.)
The other useful feature is that 'press to talk' will often work with gloves on, through a jacket pocket - so when you go AOT in the powder, you don't have to worry about digging out a phone as well, and risk losing that too.
I'd follow valais2's advice.
cheers

Well, the person's real but it's just a made up name, see?

Just to correct some of the dubious physics going on here: neutrinos will pass through mountains and virtually anything else you care to mention. That is why they are so difficult to detect and why places like Super Kamiokande in Japan were built. This is probably not useful as a communication method unless you can carry 50 million litres of water round with you, thousands of extremely precise photomultiplier tubes and a small power station to power it all. You'd then be lucky to detect more than 10 or 20 neutrinos over the course of your weeks skiing.
If you got hit by a very intense beam of them you wouldn't experience fusion, you wouldn't experience anything at all. They would pass through you and carry on as if nothing had happened. I wouldn't like to say the same if you got in the way of the lead ion beam of the LHCb experiment, that could get messy.
Radio frequency is a whole different ball game as photons interact with matter much more than neutrinos.
saikee, The 'torus' you refer to is probably a fusion reactor not a particle accelerator, while technically a torus a particle accelerator doesn't use toroidal magnetic fields to contain the beam, just beam guides which keep it centred.
Phew, I knew all that time spent at university would come in handy one day.

Must confess to having pulled a couple of birds in in my younger days, they were in the neighbouring hotel, all started with walki talkie mis comms 
So yes they have their uses!

Not so. More than half this thread has now been devoted to neutrinos. Which go through mountains like hot knives through butter - or you through beer. And you were wrong, there is no hole for them....

exactly. I know nothing about nuclear fusion but I do know that nobody built a 454 mile tunnel to fire those neutrinos through. Goodness me, chaps.  Am I the only one, when that news broke a while ago, went to google maps to see where those two places are!!!! |
They just saw you were a woman and assumed you didn't have a clue what you were talking about.

So when I used my (US bought) Motorola MJ35OR in Austria last year I was doing something illegal? Oops my bad! I seriously didn't realize that.

If it has a CE mark and is also sold in France, likely not. If not, possibly.
The R&TTE Directive pretty much lumps all of EU together for radio products (like wifi) but the French, being the French, like to find special rules that make all manufacturers jump through hoops to comply. Even for common products (like wifi, where their indoor/outdoor rules I think are different to like, everyone else).
I don't know if anyone is sure frankly about personal use and import once purchased abroad. Sales of a non-compliant radio would definitely be "illegal" / non-compliant, and presumably fines/sanctions could be imposed. I doubt it's a criminal offence to be using a non-compliant radio, unless maliciously (e.g. To disrupt aircraft tower equipment risking life, or near hospitals... Etc).
