Ham radio operators have a lot of space allocated on the UHF/SHF bands. It is quite diffifcult to justify this allocation, given the fact that these frequencies are mostly left unused (if you do not believe this, just turn on a spectrum analyzer and give a look). Reallocating a part of these frequencies to wireless carriers could bring benefits to the whole US population, reducing the digital divide.
You probably lack some knowledge about effects of EM fields on tissues. The damage possibly caused by RF fields generated by mobile phone is due to heathing, not to ionization.
BTW, most of the damage caused to tissues exposed to high doses of ionizing radiation is still due to heathing. Damage due to chemical effects caused by ionization and to DNA damage appear later in those who received exposure to ionizing radiation.
I looked briefly to some of the reports published by MTHR, and it seems to me that there is a fundamental flaw (pretty much common to many studies published on this topic). The absorbed dose from the tissues is proportional to the transmitter power. Now the transmission power of handeld devices (like GSM) depends from the received SNR at the BTS: actually a negotiation about the power to use takes place between the BTS and the handeld device to limit the transmission power, so that batteries of the handeld unit last more and interference to neighbour BTS cells is reduced. IIRC power can be varied between 1 milliwatt and 8 watt, i.e. three orders of magnitude. If this enormous variation of the radiated power (and of the absorbed dose) hasn't been taken into account in the study (as I suspect), the research conclusions are very questionable.
In a small french town (I don't remember which one, the story appeared in the newspaper about forty years ago) a bookstore owner had the habit of sending by mail books to people living close to his store. The book was accompanied by a note saying: "For evaluation. If not interested please return".
A contractor was very annoyed by this, so one night he poured a ton of gravel in front of the bookstore, and he put a sign on the top of it saying: "For evaluation. If not interested please return.".
...they wanted to sell everything on web, and in 2001 the.com bubble exploded.
Now they want to connect everything to a smartphone. Is the next bubble close to explode ?!?
Totally agree. Ham radio has become one of the most boring things one can do in his spare time.
Years ago I was into it, and I was developing some advanced DSP stuff (sort of what is known now as software defined radio, but the algorithms I was using were different and better performing than those used by radio amateurs). As I started leaking some details about what I was developing, I suddenly realized that radio amateurs were not interested into experimenting new technologies: they just wanted to buy high tech toys. So I gave up everything: I wanted people to learn science, not how to fill up a check and buy a pre-built kit. I heartily suggest you to invest your skills and your spare time into something that is much more useful than ham radio. For example I give science seminars in the high school and serve in the board of a nationwide science association, just look around: there are plenty of opportunities.
Human domestication hasn't stopped 5000 years ago, but it is going on... Our persian cat just looks cute, she realized there is no need to rub agains our legs to get food. And the largest animal she chased in all these years was a dragonfly. I am really envyous of her lifestyle...
Didier Sornette pioneered these ideas almost ten years ago. Look for example here. The same law is behind many natural and social phenomena (stock market crashes, bestseller book diffusion, etc.). I used this stuff to predict stock market crash points with limited success. A very intriguing argument, however.
One of the first computers I used was a Cray Y-MP. Now the PC on which I am typing this post is about four times faster, but I miss the Cray. I could take a nap over it, try doing this on a laptop now!
You probably never owned a mechanical watch...You know, one of those little devices powered by a mainspring, that needed to be recharged once a day. Owning one of them gave to the owner the feeling of how precious and unique is the time of our life, a sensation that seems to have been forgotten by the i-something generation.

Invite a few friends, connect all your tDCS to a ethernet hub, then attach to the WAN side of the hub this device for best result.

Terpenes are a well known component of aerosol away from cities, and studied since many years. Nothing new in the headline, after all...

'nuff said.
Please look at this paper, as well as to the other papers published by prof. Loinger.

the real Tesla would have charged cars from remote, without sending the customer a mains charger!

...the first fully functionant 3D replica of the Trinity device. When a celebrative limited edition working model will be available ?

1) Quit and get the outsource contract.
2) Bill them twice what you earn now.
3) ???
4) Profit!
password was OPE or 007. Reality seems more boring...

Does it catch fire ?
I would also like to have a phone cable rather than an antenna...

Microsoft set up some time ago a submarine fleet, whose purpose is now clear: they want to torpedo Google's fleet!
So this does mean that President Obama's calls were not intercepted, isnt' it ?
...they will start building data centers for data center surveillance.
...NASA is now using morse code to contact space ships.
