I loved his acting as much as anyone, but I disagree that it was necessarily a sad day. He was, after all, 83 years old. He beat the average life expectancy in this country by a wide margin. He made an impact on a huge number of people, as well. He was ready to check out and move on. Really, what could you reasonably expect an 83 year old man to do beyond this point anyways? I'm happy for him and all he's done.

Because it would, of course, be a terrible thing if drivers were well qualified, reasonably paid, and respected by their employers. Really, who doesn't wish they could work 70+ hours a week for 35 hours of pay? And job stability is so 1950s...

Don't order it, go to your local computer repair shop.

Who has one of those? Most of the local computer shops have been snuffed out by Best Buy and the Geek Squad. The few that survived that have been killed off by Amazon. You're likelihood of finding one anywhere that can help with older stuff is very very low.

That said, you might have some luck with placing a want ad on craigslist. Every town has old codgers who use to work at (or run) said old computer shops and they have all the adapters for this stuff that you could ever want. Several years ago I used craigslist to acquire what were likely the last 5.25 (and 5.25 / 3.5 combo!) floppy drives in the county I lived in.

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.

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.

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.

Comment: Re:Many are leaving ham radio too (Score 1) 131

The internet really sucks and we don't want another one on ham radio. Nor could we possibly have the bandwidth to support one. The entire HF spectrum fits in just a few WiFi channels.

To satisfy the demands of the "it should be anything goes" crowd, we have CB radio. And there are all of the common carriers, etc.

So, I can't sympathize, and even if I did, there are not the technical resources there.

Sorry.

An adequate bootstrap is a contradiction in terms.
