To anyone looking to acquire commercial radio programming software:
Please do not make requests for copies of radio programming software which is sold (or was sold) by the manufacturer for any monetary value. All requests will be deleted and a forum infraction issued. Making a request such as this is attempting to engage in software piracy and this forum cannot be involved or associated with this activity. The same goes for any private transaction via Private Message. Even if you attempt to engage in this activity in PM's we will still enforce the forum rules. Your PM's are not private and the administration has the right to read them if there's a hint to criminal activity.
If you are having trouble legally obtaining software please state so. We do not want any hurt feelings when your vague post is mistaken for a free request. It is YOUR responsibility to properly word your request.
To obtain Motorola software see the Sticky in the Motorola forum.
The various other vendors often permit their dealers to sell the software online (i.e., Kenwood). Please use Google or some other search engine to find a dealer that sells the software. Typically each series or individual radio requires its own software package. Often the Kenwood software is less than $100 so don't be a cheapskate; just purchase it.
For M/A Com/Harris/GE, etc: there are two software packages that program all current and past radios. One package is for conventional programming and the other for trunked programming. The trunked package is in upwards of $2,500. The conventional package is more reasonable though is still several hundred dollars. The benefit is you do not need multiple versions for each radio (unlike Motorola).
This is a large and very visible forum. We cannot jeopardize the ability to provide the RadioReference services by allowing this activity to occur. Please respect this.
The future of lightning protection

FTA: they blasted the laser some 150 metres into the sky
so,...how did they get it to stop ??
is it like a light saber ?
just here for the laugh, but still ????

Cool!
They don't mention a duration. So does that thing run all day during storms? How does that beam compare to the beam that people aim at planes and helicopters with the cheap store bought laser pointers?

Probably best to ask the researchers. As commonly happens, this stuff gets developed in a 'lab environment'. Adapting it to real world use is a completely different process. I'd wonder about how much energy it takes to drive that system, and how that would work at really remote sites that are not on utility power. Probably those would stay with traditional lightning protection systems.
I'd love to know more about this. Obviously fricken' laser beams (or any other type of laser beams) are not my area of experience. I'm wondering if the laser ionizes that little bit of air/moisture in it's beam out to 150 meters and that conducts better than other paths to ground. 150 meters might be as much air/moisture as they can ionize with the size laser they have.
I don't expect this will be replacing traditional lightning protection systems in my lifetime. But it's interesting none the less. And, I got to use the term "Fricken'" several times, which is always a bonus.
Seems like something Ms. C. Frostbite could enlighten us on with a humorous, entertaining and educational story.
I had the same thought.
I don't think @Lauri-CoyoteFrostbite usually peruses this sub. I tagged her, to get her attention.

I guess I wasn't far off:

And we shall call it Zeus.
Scientists Fire Lasers at the Sky to Control Lightning
Laser beams could be used to deflect lightning strikes from vulnerable places such as airports and wind farms
When the laser is fired, the air molecules in the beam’s path are stripped of their electrons in a process called ionization. This transforms the air, which is normally insulating, into an attractive point for the lightning to hit—effectively creating a giant, temporary and controllable lightning rod in the sky above the area to be protected.
Says it needs about 1000 watts of power. And we shall call it Zeus.
I wonder how difficult it is to land half of a 737.

Awww! Sweet--- you guys flatter me too much.....
My problem is I have a lot of lightning stories- but fortunately for me, no recent little lightning tales.
This one, below-- its probably one of my most memorable experiences------
Lightning Arrestor?
I like this photo - I spent a hairy evening in this hut (its actually a cabin perched near the summit of a 13,000+ foot mountain) during what could only be called something out of Modest Mussorgsky's ** "Night on Bald Mountain." We mostly perched on stools, the legs of which were mounted...

The use of an ionizing laser beam looks like a neat (ie: expensive) way to deal to deal with lightning- though certainly not a phenomenon unknown since -like forever.
For instance, there is an old smelter stack not to far from me that old timers relate regularly drew lightning out of the clear sky.... not because of its height but because of the ionizing mineral laden gases it shot into the air. When the smelter went SK that stopped, though its 360-some feet still make it an awesome target during electrical storms.
I have never experienced this myself, but I have heard tales of lighting coming down chimneys and wood stove flue pipes here in the high Rocky's... needless to say all my stove flues are ground'd thru heavy copper cables,

That’s very interesting! As I suspected, it’s infrared, so it won’t be blinding anyone unless they are wearing NVGs, which is definitely still a factor. Creating the path of least resistance isn’t always trivial and there will be many MANY variables at play in real world scenarios. Also, the statement “…If there’s enough energy to power it.”, is disconcerting…

Oh boy! The first thing that came to mind when I saw this photo was the scene from "A Christmas Story" where the kid got his tongue stuck on the frozen lamp post. It's no wonder my wife never takes me anywhere.
The idea sounds to me like the makings of a giant plasma cutter.
Gota have sharks. Without them Laser Beams are useless!
