PSA is not fool proof test, and is susceptible to false positives. A substantial fraction of men, in the 40+% range have prostate cancer at death. The treatments for it can be painful and have long recoveries, so there's not obvious solutions.
How many people with polio do you know? What’s her explanation of why polio almost disappeared after everyone was vaccinated? Couching a bunch of BS in “if she’s right” makes you sound like a shill.
How is the typical person supposed to decide the best path of care? How do you incentivize competition while keeping standards of care up so that people receive good care with highly complex tradeoffs.
I believe the GNURadio folks have implemented at least some of this, so it might be worth poking around GNURadio for a bit, Tags are what you're looking for.
Perhaps it's because there's little skill overlap between hardware engineers and software engineers? Perhaps it's because they have different career goals and desires?
You're assuming that parents who are homeschooling intend to provide their children with a good education. However, what about people who claim to "homeschool" their children but don't actually follow through, leading to uneducated adults who can't support themselves. I think that assuming good intentions for everyone is a problematic assumption, and you need to manage policies for bad actors as well.
Looking at the number of failed kickstarters for physical objects that are multiple orders of magnitude less complicated than a nuclear power plant with new technology might be instructive.
It's inherently a broadband device, with no output filtering. No surprise that the output is full of harmonics. I built several application specific RF front ends for Ettus SDR's at a previous job, it's mandatory for any kind of professional use.
One of many Govt focused RF companies. Start from Watkins Johnson and look at the spinoffs, although they've mostly absorbed into Bigger defense contractors at this point Boeing bought DRT in '07?
For the most part, transmitting radio in the US is only allowed in a few frequency bands, referred to as the ISM band. These have pretty strict transmit power and duty cycle limits. If you get a ham radio license, then many more bands open up to you.
Paging was also highly interested in making sure every bit that went over the air generated revenue, so adding bits to provide security was a hard sell. FLEX and ReFLEX are 90's technology.
