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.

From the announcement Soulskill mentioned below:

And effective today, we've jettisoned the Slashdot Beta platform out the side portal. Slashdot has always been a bit quirky, and "user friendly" is sometimes in the eye of the beholder. After heavily experimenting on the Beta platform and splitting traffic between Classic and Beta, we've made some decisions about which platform changes ultimately make sense: starting today, we're unifying users back on our Classic platform.

That's right. Beta has surrendered. Sanity has prevailed. We, the users, actually won.

It's oddly sad that you don't usually get to say that. But also reassuring that we get to say it of Slashdot.

I'm going to go ahead and guess you're American? Your culture seems to have this weird blind spot where the rest of the world is concerned.

You know that the populations of the USA, Israel and most, if not all, other countries with modern social systems are reproducing at below replacement levels, right?

Your personal prejudices are causing you to focus on a few niche groups. Grow up.

I'm not sure what assertion you think I don't have any evidence to back up. That babies show outward evidence of emotion? You made the same assertion with zero evidence, but it shouldn't be hard to find some. That you don't know if it's genuine emotion (whatever that is) or just outward signs of it? Sorry, you've got to provide evidence for what you know, not me.

William of Ockham would say you're full of baloney. You seem to be proposing that there's some je ne c'est quoi ("emotion") that we (and babies) have that isn't an emergent property and for some reason cannot be possessed by an artificial construct. That mystical hypothesis is much more complicated than the idea that there is no magic and things like "feeling emotion" or "looking happy" are properties of complex systems in the right arrangement.

You don't really need a supercomputer. The math involved is really very simple. Determining what the coefficients are is difficult and expensive, requiring large trials, but once you've got them your phone, plus a nurse, lab and imaging equipment, is more than capable of diagnosing the vast majority of things you're likely to get.

Most people do want a person around to reassure them. Also, until the robots get good enough, the nurse can provide an objective assessment of symptoms.

Until it runs on something other than Windows it's already locked-in.

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.

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.

Anyone who is good at electronics can get around regulatory lockouts. We're not allowed to make it easy. But nor are we technically able to make it impossible.

U.S. regulation only allows Part 95 certified radios to be used on GMRS, and Part 95 requires that the radio be pretty well locked down. But all of those Asian imports are certified for Part 90 and there are lots of users putting them on both Amateur and GMRS. If FCC wanted to push the issue with any particular licensee, they could.

If you read the article, it turned out to be someone from the RAND corporation. So you're modded as funny but.

The D-STAR issue is not really ICOM's fault. JARL designed D-STAR (not ICOM) and put the AMBE codec in it because nobody believed that you could have a good open codec at the time. We now have Codec2 (a project I evangelized and recruited the developer) which is fully open. And we do have a software AMBE decoder in Open Source, although the patents won't let us use it. That is why I am working on the patent issue (as noted in the last slide of the presentation).

I know about the counterfeit FTDI chips, and Matt Ettus told me what has happened with the Chinese clone of USRP. We know what to do.

And it's because of No-Code. We looked at the licensing statistics and thought we'd preside over the end of Amateur Radio in our own lifetimes. That's the main reason I worked on no-code. There was really strong opposition among the old contingent, and ARRL fought to preserve the code for as long as they could. Someone even asked me to let Amateur Radio die with dignity rather than sully it with no-code hams. Gee, I am glad that fight is over.

Though a nice compromise might be to allow such things in certain bands only.

That is why there are different radio services. Hams really only have a few corners here and there of the radio spectrum. There really is a service for everyone, although you should be aware that the entire HF spectrum would fit in a few WiFi channels, and all of the Amateur HF spectrum would fit in one. So, we don't really have the bandwidth at all. And people who want the bandwidth on UHF already have WiFi and the various sorts of RF links, etc.
