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.

Because "It's Simple! All You Have To Do Is..."

Not just managers. Even working for yourself won't save you. Customers as well.

At least you could get in. I had to change my resolution so I could find the edge of the login option. It was hidden under the search box.

Now that I'm in I'm still seeing overlapping options along the top edge.

Brings to mind the Maxell ad where the guy is sitting in the chair, hair blown back by the JBL-L100 in front of him.

Imagine the paper tapes instead of the L100. Except no hair would be blowing back, and I suspect the fellow would be asleep. Other than that, exactly the same.

To answer your question about connectivity, the device has 10/100 Ethernet with the Linux networking stack built in.

That's excellent. Did you build your own protocol, or did you use the mechanism RFSPACE, Andrus, AFEDRI and the various USB-to-Ethernet servers have established?

I try -- hard -- to support all ethernet based SDRs for which I can obtain protocol information.

It also has USB-OTG, and I already know WiFi and USB Sound Cards work with no additional work.

Sound card I/Q is no problem for SdrDx -- that gets the RF in, and of course I support that. The problem with the rest is controlling the SDR's settings: center frequency, attenuator, sample rate, and so on. This is because of the radical differences in USB interfacing from platform to platform.

Having said that, if you've got a working command line utility that talks to the control systems on your SDR, then SdrDx emits information via TCP that can be used to drive the command line client from a script. We've pulled this off with the Peabody and Softrock SDRs pretty well. Again, though, we run into the issue of which platform(s) the utility is available for, seeing as how they'd have to be radically different from one another.

That reading would seem to permit the Feds to override any and all State laws against political subdivisions doing anything. Some States have decided as a matter of public policy not to engage in public solid waste collection but rather to rely on the private sector for such services. Can Uncle Sam override such decisions?

I would agree with the FCC's action if it was limited to overriding laws that preclude people from starting co-ops. I think it's a bridge too far for the FCC to tell a State that it must allow a political subdivision into the telecommunications business.

*shrug*, Rush makes his living by being a showman. I don't really care for the show, though as a human being I have respect for anyone that can laugh at himself, which Rush does (he has played himself on Family Guy, amongst other things), so there's that. If you're looking for an in-depth and impartial analysis of the issues you're probably not tuning into The Rush Limbaugh Show. Conservatives see a slippery slope here to further regulation. I don't entirely discount that argument and it's hard to escape the fact that the internet became what it is today by being unregulated and free of top-down mandates that impede innovation.

I'm generally supportive of what the FCC is trying to accomplish but I think the means they're using is questionable at best. They're also going after hypothetical impediments to innovation (the oft-discussed fast lane hasn't actually happened) while ignoring real threats (data caps) to innovation. Frankly I'd rather see them in the business of regulating tariffs than telling the ISPs how to run their networks (*), because I view data caps as a far more serious threat to internet video (the "killer app" that started this whole conversation) than a fast line that has yet to come to fruition.

(*) Here's a hypothetical for you: Is it "reasonable network management" to prioritize one's voice service over other applications? Keep in mind that circuit switched voice is fast becoming a thing of the past, on both wireless and wireline. On the wireline side you've got the cable company's VoIP service running on the same DOCSIS node as your neighbor's bittorrent download. On wireless you've got VoLTE replacing circuit switched voice, so voice is just another data application there as well, one that's competing for bandwidth on an increasingly congested wireless data network.

If the answer is "Yes" then you've advantaged Time Warner/Verizon/et. al's voice product over Skype and similar offerings. If the answer is "No" then you're placing phone calls at the same "best effort" level as your neighbor's porn addiction.

That model does make sense for the internet and very few people argue with pricing broke down by speed tiers. It breaks down when people expect that they can utilize 100% of their pipe 100% of the time. In my area Time Warner sells 50mbit/s connections and has eight DOCSIS channels on their coax plant. At ~42mbit/s per channel that's a maximum of 336mbit/s shared amongst all users on a particular node. Some simple division will reveal that less than seven users subscribing to the highest speed tier are enough to completely saturate that pipe. You can translate this into your water analogy easily enough by observing what happens to your water pressure when the fire department decides to flush the hydrants in your neighborhood.

Caps really aren't the best way to manage this "problem" because they ignore the actual limiting factor of bitrate. 95th percentile billing would make more sense but good luck explaining that to the masses.

Rush Limbaugh remembers the days of the fairness doctrine. There are a handful of politicians who think it should make a comeback. I'm not a big fan of Mr. Limbaugh's but in his defense if you read what has been said by supporters of the Fairness Doctrine it would send shivers up your spine:

The shooting is cause for the country to rethink parameters on free speech, Clyburn said from his office, just blocks from the South Carolina Statehouse. He wants standards put in place to guarantee balanced media coverage with a reinstatement of the Fairness Doctrine, in addition to calling on elected officials and media pundits to use 'better judgment.'

Most people, left or right would recoil whenever a politician starts talking about a need to rethink the "parameters of free speech."

If you're a Libertarian how do you feel about the second vote, the one where the FCC is claiming for itself the authority to preempt State level legislation against municipal broadband services? I am not a Libertarian, nor a Republican, but I find that vote extremely disturbing; it has always been the sole province of the States to set the parameters within which their political subdivisions operate. If New York State wishes to preclude my municipality from setting up an ISP what business is that of the FCC? Can the Feds also preempt a decision that precludes municipalities from operating solid waste services? Sewer services?

I am generally supportive of what the FCC is trying to do with Title II but they're going a bridge too far if they think it's appropriate to step into the middle of the relationship between States and their political subdivisions. Three of five unelected Federal bureaucrats do not get to override the parameters my State Legislature sets for my city.

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.
