Er, no.... on my own equipment my voice drives the phase modulator directly. At no point is it digital, though it DOES use transistor amplifiers, digital controls, and a digital synthesizer to drive the oscillators. Unless you're arging that information is data, and it is. But in the context I'm talking about, we mean Phone vs Data - analog audio vs text.
Donald duck is what you hear when you are listening to the wrong sideband, or are "off center" of the sideband. That's not anything to do with scramblers, that's just someone with bad or poorly-operated equipment not understanding what they are hearing.
From what I've heard on the air, it's usually just like you said - long distance nonsensitive communication tends to be open (for a variety of reasons) but the tactical frequencies usually are (and should be) encrypted.
Still, a smart criminal will know what that signal sounds like, and know that hearing that in close proximity is bad news.
quick note: i'm talking about phone operation. data is digital by definition, I know, but the analog transmission systems suck as MFSK or PSK tend to be quite robust as well.
Not a radio operator are you? Digital systems don't work so well with interference or weak signals. On a digital system you'd end up with garbage or silence where without the cipher and digital codec, you might actually be able to hear them through the noise. So, there is a distinct advantage to open analog.
That said, encryption certainly has it's place. Squad-level tactical circuits for SWAT, for example.
Circular. This invokes 1) Save the Children and yet conflicts with 3) as clearly the only way to accomplish it is to deploy the cyber-terrorist children.
The fun part is there is a good chance we'll have a rebound and get another Republican president. Here's to hoping that doesn't happen or the stars align and we get a Republican in office who decides not to act like the rest of the bunch currently are.
US politics suck. That we can't seem to elect anyone except D or R seems to be a large part of the problem.
I'm one as well, have been since August. Got 'general' class license. I'd give you my call but I don't have a P.O. box on my license, so anyone on slashdot could get my home address super easy...
(you are welcome to send me an email though if you do want my call for some reason)
Lets not forget that this would instantly become obvious too, because the data flow would stop. Generally you've failed if they notice something happened.
Because you have corps that build things that need exorcise too? Might as well have one big project with multiple uses.
Logistics guys get practice... logisticing? Engineer guys get practice building. Sat guys get free calibration and practice doing their stuff. Bombardiers and other munitions guys get practice shooting at it. Intel guys get practice doing damage assessments. R&D probably gets a chance to test a bunch of stuff, too.
For example, the DemandProgress guys have been fighting the internet backlist bill for a while. Just yesterday I got a notice that 800,000 people had sent correspondence to their representatives about it. That's just the ONE group... and almost a million people.
This bill keeps getting put on the table and slapped down. I'm hoping (perhaps naively) that we have something to do with it.

Federal and police radio don't have static keys. There are mechanisms for rekeying.
See Project 25 for a starting place if you want to go digging.
Yea, because Washington totally isn't already on the encryption bandwagon...

Once upon a time I used Adobe's postscript printer driver and a linux postscript definition file to get one of them to work. That was crazy stupid.
Yea, the official response is "try again" - lol!
Quake. Nexuiz uses the darkplaces engine, which is the first quake's engine redone :)

I'll beat you here...
I was in a testing session a few weeks ago. I watched a girl barely over 10 years old pass her test for a general class license.
Rotary Wombat - what even is that?

Yea, I was thinking the same thing.
Oh look, Italy is out of money! (continues eating $5 cupcakes)
Not enough to matter, unless the unit was airtight (it wasn't)

Maybe I'm missing your meaning. But syslog works fine via UDP.
I'm pretty sure phones don't have the optics to do that. Even if the focus was good enough, you'd need polarizing filters, vibration compensation etc.
My $200 camera? Perhaps, but it's not going to be doing it live.

Stop putting your reply into it.
It's called respect, bitch. You call a man "sir" until you know otherwise.

The list goes on. The question is "why not?"
Well, it's a bombing range too, apparently.
I wouldn't doubt they used it as an exercise engineer corp as well.
Well, not entirely.

Well, speaking for myself, because it's mostly full of people like you.
