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 so

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.

But will the computer add appropriate tagging and links?

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

Why is that a problem?

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

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? This site has a good history htt

WiFi is hard to support, it's very complex from a signal processing and timing perspective.

Well, it would also cost at least 10x what a dual purpose LoRA/WiFi radio would cost if it were built out of LoRa parts from Semtech and an ESP-32.

It's not a tools problem, it's a people problem. Use whatever tools your team is used to, and build culture on top of that.

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

One of the last gasp paging technologies was two way paging, which included a slow return channel to confirm message reception.

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.
