Comment Re:This is real risk. (Score 1) 82

Actually, the instruments are operating within their specified tolerances, which were approved by the same government that in turn sold of the necessary buffer spectrum.

The GPS navigation systems are evaluated by the government and are issued supplemental type certificates with approved model lists of aircraft in which they can be installed.

The problem is that the government approved the GPS navigation systems and then allocated spectrum to some other use which was necessary to remain unused for these GPS navigation systems. We're not just talking about navigation systems manufactured 30 years ago. Systems are failing that cost $15K when they were installed *last year*. For a general aviation pilot who flies 100 hours a year at a usual operating cost of $80/hour, swallowing another GPS upgrade is equivalent to multiple years of normal operating cost. It's prohibitively expensive. I digress...

By the way, I hold a radio license for my aircraft, and it wasn't free... and neither is the airman certificate. Pilots and aircraft owners already pay tons for licenses and equipment certifications. If we buy a navigation system type certified by the government, the government shouldn't defeat said navigation system within a reasonable service life.

To add to this whole mess, about half of the VOR system which backs up the GPS system is inoperable at the moment.

The government royally f'd up here.

Comment This is real risk. (Score 4, Informative) 82

I am a pilot and an aircraft owner. My aircraft is certified and fully equipped for IFR using traditional navaids (I have two nav radios, one with a VOR/LOC indicator and the other with a VOR/LOC/GS indicator). I also have a WAAS GPS receiver which I use for navigation.

GPS operates in the L1 band with a carrier frequency of 1575.42 MHz and a bandwidth of 13.345 MHz.

The telcos are operating "5G" channels with carriers between 1475 - 1518 MHz and bandwidths of up to 20 MHz.

I can tell you that very recently, when I pass over certain urban areas near newly erected 5G towers, the GPS reception goes bonkers. It's really disconcerting when you are flying the plane for your annunciator to start yelling "terrain pull up" at you when you are at 3000' AGL. The frequency allocations are just too close together. You could put really narrow bandpass filters on the GPS receivers in aircraft, but this will be a very, very expensive process and will be very time consuming. All the avionics shops in the southeast are backed up for months and months. Filters installed in aircraft require TSO approval, and a change in equipment requires that the IFR certification on the aircraft be redone.

Three of these towers just went up around my hometown in the mountains of North Carolina... Someday soon, someone's annunciation system won't go off and a pilot flying in unfamiliar territory or in a high workload situation is going to fly an aircraft into the side of a mountain who would have otherwise lived.

I see a lot of propaganda out there from the telcos saying that planes are not falling out of the sky in other countries... but airspace conditions and radio spectrum congestion are a lot different in other countries (as are the frequencies themselves). Remember, just about everyone in this country will eventually have a transmitter operating in this spectrum in their pockets.

How many people need to die before the government realizes how badly they screwed up and does something to solve the problem? Either shift the frequency allocation, or subsidize the retrofitting of the aircraft navigation systems. Regardless, this is going to take a lot of time.

Comment Human elimination required to get to zero carbon (Score 1) 81

Don't you have to stop employing those pesky breathing humans to eliminate carbon emissions? Last I checked, humans eat carbohydrates, inhale molecular oxygen, oxidize the carbohydrates, and then exhale carbon dioxide plus water vapor. It goes something like this:

C6H12O6 (s) + 6 O2 (g) 6 CO2 (g) + 6 H2O (l) + heat

To summarize, Microsoft must be planning on completely eliminating their workforce.

There is very little in the FCC tests about cordiality. I wouldn't say we are "vetted in polite behavior". We are vetted in our knowledge of electromagnetic physics and in our knowledge of the rules (FCC part 97).

The hobby attracts an eclectic group of people, admittedly mostly men. My local club has PhD's in mathematics, infosec professionals, landscapers, veterans, people from all walks of life. It's a fantastic way to get out of your everyday social bubble.

Regarding training real adults, I am heavily involved in the BSA and my wife is heavily involved in GSUSA. Our ham club offers joint licensure prep classes to both girls and boys. I believe amateur radio to be a fantastic, perhaps the ultimate, STEM activity for Scouts. There is a lot of hype about STEM out there, but way too much fluff when it comes to actual activities. These kids get to take an 8 hour crash course in physics, earn a license, get a free radio, and then use their radio knowledge to communicate with people near and far.

It remains useful in real life scenarios, too. As I type this, ARES operators are providing communication to Red Cross shelters across eastern NC where the power (and traditional communications) could be out for weeks. Hundreds of hams were deployed to PR after Maria. Take down the cell towers, kill the power grid, and I'll show you that I can still relay messages to people thousands of miles away. It's a powerful tool.

Now, if I can just get one of my teenagers to quit griping about the aesthetic impact of three antennae on my Jeep...

I have a friendly, very ordered conversation with about 30 people every Thursday night on WW4L repeater (147.360 MHz FM +). We seem to be able to do that just fine. Everyone waits their turn to speak.

That's nothing compared to the Saturday night "6600" net on N2GE up on Mount Mitchell. They might have 150 check in on a Saturday.

Hams overcome our conversational quantity limits by having clear customs for who should speak when.

Real nerds get FCC licenses.

We know how AT&T handles this sort of thing with TV networks.

Next week, you'll go to Netflix.com and they'll start showing modal popups saying AT&T has decided to deny access to Netflix in a few weeks, and to call AT&T and let them know how you feel.

Three weeks later, you'll go to Netflix.com and get a certificate error: bad CNAME. Users who are idiots enough to click through the errors will see a marketing-crafted propaganda video about how Netflix has chosen not to share their content anymore with AT&T subscribers, and to call Netflix and let them know how you feel.

Invariably, this will occur right when some major season finale is supposed to air.

The Internet should be a utility. It should just be metered and paid for by the consumers, who should be able to freely change their caps. Who cares how they use the bandwidth they pay for?

I was a late adopter for smartphones. My wife used Virgin Mobile (US) for several years - she got a lifetime "unlimited" deal but after Ting came along it was plain cheaper. Both were Sprint MVNO's, but now Ting lets you choose T-Mobile or Sprint on a per-phone basis and puts the phones *on the same bill*. You can set alarms and cutoffs for your kids, etc. I have four lines on the same bill and rarely go over $80/mo.
