Yes, and much of the digital communication (most?) is P25 in the clear, which can be decoded with consumer-grade scanners.

Thats interesting - thank's for the info.

By contrast, not only in the UK, but across most of Europe, a concerted effort has been made over the last decade to transition public service & utility comm's to Motorola/TETRA - with much of it enciphered (albeit in most cases with a basic key - excepting the key/s used by various police forces, who have always opted for the strongest key usable).

A big issue in early days was the suitability of TETRA in subterranean environments.
Many of Europes' capital cities have underground tube systems and both the TETRA hardware and firmware/software was not originally designed with underground usage in mind. That "problem" has been addressed properly over the last 5 years or so, and it is now possible to link an officer underground one end of London, with an officer above ground on the other side of London.

Is it illegal to have a scanner radio in your vehicle in Oakland, CA? I'm thinking if it is, then the article probably has more to do with that, then the streaming itself.

I also read this somewhere... If I hear something on my scanner and then go tell somebody about it... that would clearly be against the law. Now if my scanner is on... and somebody passed by my window and heard the same thing on my scanner... :)

I didn't say that it's illegal. I said that that link does not establish that it isn't illegal.

What other laws then. It says it is not in violation with the FCC and if there are no other laws out there concerning it (which I have never heard of any since it would be up to the FCC anyways on this type of thing) then it must not be illegal.

I don't think it is illegal. But you can't rely on that link as proof, because the FCC does not make all laws. The letter clearly only deals with FCC rules, so the only thing it establishes is that it's not a violation of FCC rules to stream a scanner over the internet. The laws that are most often brought up with regard to streaming are copied in this thread (note that I'm explicitly not saying that they make it illegal), where you've also challenged my assertion that the FCC doesn't make every law in the universe.

Quote the law that states streaming a scanner over the Internet is illegal then...

Well, there's this from 47 USC 605 (which, to my knowledge, is not part of the "FCC rules"; if that's correct, a letter from the FCC saying anything about "FCC rules" is irrelevant, as ibagli has pointed out a few times):
No person not being authorized by the sender shall intercept any radio communication and divulge or publish the existence, contents, substance, purport, effect, or meaning of such intercepted communication to any person.​
(emphasis added)

Absent any other statutory text that says "divulging or publishing intercepted, unencrypted, Part 90 public safety communications is OK", the above-quoted statutory text seems to control.

There are more details in this post: http://forums.radioreference.com/li...ve-audio-broadcasts-archives.html#post1328895. In that post, I describe why I think the general "for the use of the general public" exception to section 605 does not necessarily apply to intercepted public safety comms.

Don... is 47 USC 605 and Chapter 119, Title 18 § 2511 the only thing you are referring to with this. The reason I ask is that I have a lawyer friend who I might ask to look over it if he is willing to and have him give me his professional opinion. I mean I know even his opinion isn't the law, I would just like to have a professional opinion on it. I am sure Lindsay has had someone give their professional opinion on it and I just would like someone who knows a little more about law tell me what they think. This isn't to bash you or ibagli just to see what someone with a little more knowledge of law thinks. By the way thanks for the great software :) . I own Win 96, 97, & 500 and by far they are the best software out there for their respective scanners.

What's a 'basic key' and 'strongest key' as far as underground usage is concerned?

A big issue in early days was the suitability of TETRA in subterranean environments.
Many of Europes' capital cities have underground tube systems and both the TETRA hardware and firmware/software was not originally designed with underground usage in mind. That "problem" has been addressed properly over the last 5 years or so, and it is now possible to link an officer underground one end of London, with an officer above ground on the other side of London.
You may also want to explain those claims more in detail, in particular how a TETRA signal propagates differently to a signal based on another standard. And how exactly does firmware come into play here?

Me thinks coverage problems underground and in tunnels can be solved by using a repeater (booster) or putting a base station down there and connecting it to the RF distribution system (subways for example often have a network of leaky feeders and/or indoor antennas), and those solutions do exist for more than 5 years.
