All I can say is that Weo is one of the smartest guys I know (his wife is no slouch either!)

He has been involved in Laser related research since I met both of them back in the 1980s. He also has some note from ham radio world where he and N6KL wrote something called ARESDATA that provided a real time database available on packet radio.

I was unemployed for about 6 months at the beginning of the down-turn 3-4 years ago.

I submitted maybe 10 resumes a day through Dice/HotJobs, etc. I live in Silicon Valley and have 30+ years as a chip designer. I learned a few things through the process.
1) Submitting your resume seems pointless. I NEVER received a call from that process.
2) Use your network of friends. I finally DID get a call from someone I'd worked with 15 years before and received a 2 month contract position that got me back into the job market. I maintained these relationships/contacts through LinkedIn.
3) I had kept my resume unsearchable because I was technically "furloughed" and my original company was still paying my family health insurance. I didn't want to loose that. As soon as I had the contractor position I formally terminated my relationship with my previous employer and was free to advertise. I got two interviews and one job offer within about a week of making the resume searchable on Dice.
4) Use/abuse head-hunters.They know where the jobs are!

How well is that going to work in CA where the big problem is just finding water at the moment? We won't talk about all of the incidence recently where millions of gallons were released like at UCLA (Uggh!).

Actually having been to a couple of wild-land fires with what was then called CDF in an auxiliary capacity I do have some knowledge of the process. The reality is that just plain H2O is used as often as retardant, and that all kinds of aircraft are put in to service for air-drops.

The big thing about the DC-10 is carries a lot of H2O! It is also going to be limited as to what areas it can drop in. CA is a hilly place and there are some terrain features where it wouldn't be safe to take such a large aircraft. We also have copters and smaller fixed wing aircraft in use. They all play a part.

So this comes along just as Russia drops the word "Nuclear" to remind everyone that they have them.

Are you naive enough to believe the Russia would bother to show up to negotiate about this?

One also wonders what the people of Ukraine think about such a well timed suggestion.

Why don't these guys simply pay attention to a scientific poll that was already run in Eric Cantor's district to see how successful this idea is!

Sheesh!

First time in history that Majority leader of the House has lost his seat- all because he supported some form of immigration reform.

According to an article in last weeks Aviation Week and Space Technology - you are ignorant.

The value of commercial experimentation on the ISS has taken an unforseen upswing. Real companies are paying Real money to put experiments of different varieties on the ISS.There is a back-log of customers.

I'm thinking the Dragon from Space-X is a nice answer to the Russian suggestion. I also think their minister needs some remedial science classes to learn about the law of gravitiy.... you can't possibly reach escape velocity with a trampoline ;-)

If you are not already, fill out the paperwork to incorporate the club under 501(c)3 non-profit paperwork status.

Request grants from local and national businesses

Our club regularly receives such money in the $1000-$5000 range from local utilities, national cellular providers, large box discount chain stores and grocery stores

These types of businesses have ready-made grant requests - sometimes right on their websites They are looking to give their money away You do need to meet their criteria... usually to be a 501(c)3 not for profit and provide community service.

The answer to your problem is called the Rolling Shutter Effect.

You can simply make ALLl the lights in the cabin strobe at a frequency close to the rolling shutter speed of the cameras most people have. Or at 2, 3, 4, or more times that speed.

Much like old TVs digital cameras take pictures in strips. by picking the right frequency you can cause bands of lightness and darkness in the image, ruining the photo.

You can then choose a camera which is less or not susceptible or synced with the strobe effect to mitigate its effects.

The strobe would be rapid enough to go unnoticed by the human eye and really mess with electronic cameras.

But there are cameras that some people have that may not be effected by it, but most cameras have some issues with it, so your mileage will vary

First there are really two types of missile defense systems. Those that worry about ICBMs, and those that are "theater" defense.

The US Missile defense system that is costing so much money worries about the first class, i.e. missiles coming from thousands of miles away that are ballistic in nature. We have a limited number of shots for such a defense - and really we're worrying about bad actors like North Korea or perhaps Iran. These guys are going to have a limited capability to throw things at us. So a small number of shots is about right.

These systems can NOT defend against Russia - who can throw several hundred missiles our way.

The theater defense systems are things like the Patriot or the SM3 (I think) that the Navy carries. These have some ballistic defense roll - but their main job is to worry about shorter distance ballistic missiles or air-breathers like the Exocet that was used in the Falklands war. A Hypersonic missile is going to fall into this class and indeed I believe such systems would be out-classed by a Hypersonic weapon today.

Perhaps with the next generation Laser weapons there might be a chance to defend against multiple salvos - but those aren't fielded yet.

I've used codec2 daily in the ghpsdr-alex branch for controlling SDR over Linux remotely.

It is deployed on the Android App glSDR that you can find in the Android Market.

The app provides a GUI with spectrum & waterfall along with Audio from the radio being controlled. Codec2 is used to provide a low-overhead transport that survives the Internet quite nicely.

I've used the app with my 4G phone quite successfully.

Now to the question of latency. When I connect to my own radio with a real-time playback PLUS the codec playback running at the same time, there is a fraction of a second delay - perhaps 100ms-200ms at a guess.

So bottom line is there are real applications for Ham Radio already deploying this technology.
