We implement it as a chip that intercepts the serial bus to the VFO chip, and disallows certain frequencies. On FCC-certified equipment we might have to make that chip and the VFO chip physically difficult to get at by potting them or something. This first unit is test-equipment and does not have the limitation.

My main interest in this SDR project would be as part of a home-brew RF/digital test/research bench for a variety of mobile cell-based equipment and development of new types of devices for new uses.

How does a company like Harris Corp. get away with manufacturing/selling Stingrays for use in the US, and can this project possibly use the same technical exceptions used by Harris Corp. to negate the requirement to artificially cripple it?

In a surprising move the Supreme Court of the United States took unprecedented action, active pro actively they endowed artificial intelligence with political beliefs, religious beliefs, freedom of expression, right to form associations, the right to petition government, and voting rights. Chief Justice Roberts said, "What the heck? Why wait for some astro-turf group to fake a grass root campaign, force a pointless lawsuit and wind its way all the way back to us? This is more efficient."

The receiver has a block on certain cellular frequencies in the 800MHz band. This is the only restriction. The radio can tune to any frequency between 50MHz-1000MHz, otherwise.

Is this block implemented in software or hardware? Could it theoretically be bypassed/removed by someone technically oriented?



Lawmakers Seek Information On Funding For Climate Change Critics 373

Posted by Soulskill
from the all-about-the-benjamins dept. writes: John Schwartz reports at the NY Times that prominent members of the U.S. House of Representatives and the Senate are demanding information from universities, companies and trade groups about funding for scientists who publicly dispute widely held views on the causes and risks of climate change. In letters sent to seven universities, Representative Raúl M. Grijalva, an Arizona Democrat who is the ranking member of the House committee on natural resources, sent detailed requests to the academic employers of scientists who had testified before Congress about climate change. "My colleagues and I cannot perform our duties if research or testimony provided to us is influenced by undisclosed financial relationships." Grijalva asked for each university's policies on financial disclosure and the amount and sources of outside funding for each scholar, "communications regarding the funding" and "all drafts" of testimony. Meanwhile Edward J. Markey of Massachusetts, Barbara Boxer of California and Sheldon Whitehouse of Rhode Island. sent 100 letters to fossil fuel companies, trade groups and other organizations asking about their funding of climate research and advocacy asking for responses by April 3. "Corporate special interests shouldn't be able to secretly peddle the best junk science money can buy," said Senator Markey, denouncing what he called "denial-for-hire operations."

The letters come after evidence emerged over the weekend that Wei-Hock Soon, known as Willie, a scientist at the Harvard-Smithsonian Center for Astrophysics, had failed to disclose the industry funding for his academic work. The documents also included correspondence between Dr. Soon and the companies who funded his work in which he referred to his papers and testimony as "deliverables." Soon accepted more than $1.2 million in money from the fossil-fuel industry over the last decade while failing to disclose that conflict of interest in most of his scientific papers. At least 11 papers he has published since 2008 omitted such a disclosure, and in at least eight of those cases, he appears to have violated ethical guidelines of the journals that published his work. "What it shows is the continuation of a long-term campaign by specific fossil-fuel companies and interests to undermine the scientific consensus on climate change," says Kert Davies.

Technology has been decimating jobs since the industrial revolution. But all the jobs destroyed were in India and China. They had 25% of the world GDP before industrialization. They had even higher fraction before the age of exploration distributed cash crops (sugarcane, tea, coffee, breadfruit, cotton) around the world. So for centuries all the philosophers, economists and sociologists did not even understand the full impact of the industrialization. Mostly they saw it as political issues, colonialism, anti-colonialism, etc etc.

Read the The Rational Optimist by Matt Ridley to get an idea of the doom and gloom being predicted for centuries. Matt takes the view all these gloom predictors were wrong and the industrialization is an unadulterated success for humanity. He seems to think humanity consists of Europe and USA. This review sums it up nicely

The job destruction is also accompanied with wealth transfers and power transfers. Finally the job destruction finally lapped up the shores of Europe and USA by 1980s. Slowly middle class of America is waking up to what has been done to them. Their jobs are gone. The "wealth" they have as home equity is a fickle fictional paper gain. Their pensions are gone. Their investments in 401K funds is being used to transfer more power to the top 0.5% of the rich.

Typically very smart and hard working people end up in the top 2% by income and usually end up in the band 98th percentile and 99.5percentile. (To reach the top 0.5% you must have inherited wealth or take huge risks and be lucky). The wealth transfers from third world to industrialized nations had run its course, wealth transfer from the bottom 80% to top 20% has run its course. Till then these guys were very happy and egging it along. Now there is no real wealth left below 90%. The momentum of the economic policies set in motion by them is taking money from the 90 to 98 band and moving it to the top 0.5%.

If you finish college and get in to the 99% cut off entry level salary and stay exactly at the 99% cut off all through your career, it is not enough to get you into the top 1% by wealth (5 million according to IRS and 8 million according to the feds). Till about 2000s, top doctors, lawyers, accountants routinely made it to the top 1% without inheritance. Not any longer. Citation provided

This is meant to be an entire FCC type-approved transceiver with spurious emissions low enough to amplify to the full legal limit for the band.

Does being FCC Type approved mean there are certain frequency bands that are verboten? In other words, is the coverage continuous from 50mHz - 1gHz or are there required gaps?

I know that communications receivers capable of covering the cellphone bands were made illegal to sell in the US a while back. Just wondering how SDR will deal with such legislation going forward.

This may be a real concern where a SDR may cover bands where things like cellphones and police/military/air communications live and are heavily regulated and some portions restricted from even reception by unauthorized persons. Aren't many trunked police/fire/EMS radio systems in the 800mHz band, or is that dated? It's been a long time since I held an amateur radio license.

Comment: Solar hurts the profit margins a lot. (Score 2) 353

Typically the grid operates at full load on sunny days in the afternoon when all the airconditioners are at full blast. The spot price for electricity fluctuates a lot. And most utilities buy and sell power in this spot market where they make most of their profits. The base load is just 40% of the peak load and there is so much of excess capacity electricity basically sold at cost or at a loss.

Enter, Solar.

It provides power exactly when the demand peaks. If solar meets the peak power demand, the spot price for electricity will fall. For brief period an Australian utility had to sell power at *negative* prices at the peak! There was so much solar power feeding into the grid, they had to pay people to take their power, lest their generators overheat and burn.

The amount of solar electricity created might be small in terms of energy produced. But when it comes to profits, this probably cuts deep into the profits of the utilities.

Eventually the utilities will reduce their peak capacity to create an artificial shortage and trade. The net metered roof top solar energy is bought back at wholesale prices by law. They typically get sold instantly in the spot market at peak prices. The utilities are making tons of money on the net metering, all their talk about roof top solar being free loading is just bull shit.

The whole concept of Intellectual Property is created by the government, and you need government to enforce it. When regular real estate is subject to eminent domain, why patents, copyrights etc should be above it? If some drug company develops a drug that can cure Hep-C and is profitable enough to sell it in third world countries for 20$ a dose, but insists on charging 160,000$ per dose for USA, I think the government should just step in, take over the patent based on eminent domain, pay the company something along the lines of what is suggested in the summary. Take a billion or two, and the entire cost of development, testing and regulatory approval too. But we can't let the drug companies game our government and treat us like a milch cow.

Of course, we don't fully what the rules will do since they have been acting in secrecy!

They will be published when they are finalized.

We have to give the government the power to regulate the internet before we can know what they'll do to the internet.

Wait, this sounds sickeningly-familiar....

Oh well. I'm sure it'll be fine.

After all, it's only the same FCC that has pursued a "wardrobe malfunction" for nearly 8 years, pushed for the Fairness Doctrine, and whose "Diversity Czar" Mark Lloyd was quoted as admiring the way Chavez seized control of radio/TV/media and placed them under State control.

I'm sure porn and less mainstream media outlets, political blogs, forums, etc that the government may dislike will have nothing at all to fear. /s (for the clueless)
