You have the Part 15 and ISM services for that. You really can buy a microwave link that's metropolitan-distance and legal to use.

We lost much of our 440 capability to PAVE PAWS in California. Remember, Amateur Radio is not the primary service on many bands. The military is on 440.

If you want that nearly infinite microwave spectrum, you have the Part 15 and ISM services. Absolutely nothing is stopping you. Power is not the issue with those frequencies, it's line of sight and Fresnel zones.

No, I absolutely do not have to prefix my words with anything. You do that by posting as an anonymous coward. I use my real name to indicate that I stand behind my words.

Yes. The usual mechanism here would be WiFi security, with HTTPS or SSL inside of it.

OK, no real technical data and some absurd claims here.

First all-digital transceiver? No. There have been others. Especially if you allow them to have a DAC and an ADC and no other components in the analog domain, but even without that, there are lots of IoT-class radios with direct-to-digital detectors and digital outputs directly to the antenna. You might have one in your car remote (mine is two-way).

And they have to use patented algorithms? Everybody else can get along with well-known technology old enough that any applicable patents are long expired.

It would be nicer if there was some information about what they are actually doing. If they really have patented it, there's no reason to hold back.

It is actually kind of sad if you know their history.

Back in the day they were competing with Palm, and had Windows CE and Pocket PC 2000. When PocketPC 2002 came out my employer switched over from Palm and I got to rewrite a bunch of tools. They did pretty good for a while with Mobile 2003, and Windows Mobile 5. It knocked Palm down several notches in the mobile market, with Palm losing value and getting bought out in 2005.

The fun thing about that era is that there were phones with PDAs in them, you can go back to "Pocket PC Phone Edition" for that. Each version of Windows Mobile supported running in phones, but they never took off.

The iPod was getting some power and some apps, but I loved that with a single CF card I could have my entire music library on my device; the Axim x51v used the same audio chipset as the iPod of the era coupled with better playback software where you could mix and such. It also offered all kinds of apps making the device useful for the other common tasks of the time like calendar, email, and web over both wifi and bluetooth.

Again you could get phones running WM5 and WM6 with all their apps, and in late 2006 they had 51% of the market. Blackberry had 37%, Palm was 9%, and Symbian at 9%.

Then came the iPhone. At the time I didn't really see the reason for the hype, when it came to processor power, memory, and even 3D graphics the iPhone was less powerful than my Windows 6 phone.

As the numbers came back, iOS rose and WM feel by the same percent; the other companies were flat in market share. By early 2007 Windows Mobile drooped to 42% and iOS was at 11%. By 2008, WM had 29% and iOS 19% and Android had entered at 2%. By 2010 Windows Mobile devices had dropped to 7% market share, Blackberry had dropped to 25%, Palm to 3%, and Symbian at 2%.

Phones running Windows Mobile continued to exist, but that's about it. Three more versions of Windows Mobile, the three editions as Windows Phone, they have never been able to get their market share back anywhere near 2006 levels.

I saw a 'gator right at the edge of the VAB parking lot last month. In a drainage ditch, up to the fence, cars parked right on the other side.

With luck, they'll start incorporating our radio transceivers. I hear that SpaceX flies with several USRPs now, so that's not completely unrealistic. That might be as close as I can get. Anyone who can get me a base invitation, though, would be greatly appreciated and I'd be happy to do some entertaining speeches while there. I need a base invite for Vandenberg, too. I got in to the official viewing site for the first try of the last launch (and that scrubbed too), but this next one is on Pad 6.

I was in Florida to speak at Orlando Hamcation and went to see the DISCOVR launch at Kennedy Space Center. I paid $50 to be at LC-39 for the launch, an observation tower made from a disused gantry on the Nasa Causeway between the pads and the Vehicle Assembly Building. A crawler was parked next door! A hot sandwich buffet, chips, and sodas were served. It was cold and windy! I watched for a few hours and unfortunately the launch scrubbed due to high stratospheric winds.

The next day, Delaware North Corporation, which operates tourism at KSC, decided not to open LC-39 or the Saturn 5 center for the launch. This was the third launch attempt and I guess they decided most people had left. I was annoyed.

The closest beach was going to be closed in the evening, it's a sensitive ecological area. I ended up seeing the launch from Jetty Park. This turned out not to be such a great location, the tower wasn't visible at all and the first 10 seconds of the rocket in flight were obscured before we saw it over a hill.

What's a better viewing location?

We see articles about how few people are scientifically literate, and so many on Slashdot decry "We are geeks, we understand science!"

Appearently, nope!

Scientists, the astronomers who spend their days and nights studying the stars and planets, people who are intimately familiar with the definitions, and people whose life work and career funding depend on them, came up with a set of definitions.

The definitions draw a line somewhere, and you can argue they are as arbitrary as a meter and a kilogram, or a foot and a pound. You can spend your days arguing that the measuring stick is the wrong size, or spend your days convincing the rest of the world that they need a different measuring stick, or otherwise be a nay-sayer and contradict the consensus of the scientists.

But to decry that because you learned something one way, therefore that convinces you forever, that's just plain stupid.

Test equipment is allowed to transmit and receive on those frequencies. If it looks like a radio, it can't. I have a number of cellular testers hanging around here that can act like base stations, mostly because I buy them used as spectrum analyzers and never use the (obsolete) cellular facilities. Government has different rules regarding what it can and can't do in the name of law enforcement, although FCC has been very reluctant to allow them to use cellular jammers.

If you can afford it, something from Ettus would better suit your application.

We think after we build this new PCB we can go for the croudfunded manufacturing run. It's mostly surface-mount, and we expect to sell assembled boards in this run, and then the next version will be fully-packaged radios.

Hi AC,

Matt Ettus has a story about a Chinese cloner of the USRP. The guy tells Chinese customers that it is illegal for them to buy from Ettus, they must buy from the cloner instead. Then, when they have problems and require serivce, he tells them to get it from Ettus. Who of course made nothing from their device sales and can not afford to service them.

This is not following the rules of Open anything. It's counterfeiting.

So, sometimes it is necessary to change the license a little so that you will not be a chump. I discussed the fact that the hardware is fully disclosed but not Open Hardware licensed with RMS, the software is 100% Free Software, and there is a regulatory chip you can't write. We can go for Respects Your Freedom certification that way..

I've paid my dues as far as "Open" is concerned, and Chris has too. This is all we can give you this time.

The case selection was so that we'd have at least one case that would work. We did not take much time on it. We'd be happy to have other people designing and selling cases.

The version after this one requires cases that look like real radios. That is going to be a bigger problem. We don't yet have a mold-design partner, etc.
