Not much in practice.

Different max power limits (not an issue on a portable), no forced narrowband for RTTE, and they supposedly need that "cyclic keying" power ramp up/ramp down function turned on in Motorola gear.

Hello.

That's because the TRBO radios they showed pictures of in the paper are TRBO radios :baby: C4FM mentioned in isolation means absolutely nothing at all . There's a lot more to any digital voice signal than the modulation scheme. They said in the paper that they're coming up with their own homebrew th...

That's pretty common with most stuff you buy there, even in supermarkets etc.

My girlfriend taught English there for six months, she speaks almost no Japanese but she got by fine because of this.

NXDN Mixed mode repeater ftw Any P25 repeater will do mixed-mode too. If the Detroit guys were naive enough to make theirs P25-only well, that's their misfortune. ASTRO only is a good thing. Around here there's tons of repeaters hardly anyone uses anyway, and with mixed mode you get old farts who d...

If you're going to drop $700 on a radio, it's kinda nice if it comes with something to protect your investment

mr.syntrx

The only thing you miss out on as far as I can tell with not officially having IPSC in the subscriber is Roaming, where Motorola took Voting Scan, gave it a new name and pretended it was new. If you don't use it anyway, it's no big deal.

mr.syntrx

For a portable radio, the main difference is $5000

Also, can D-STAR send encrypted credit card numbers from a remote terminal over the air back to the main box which is interfaced to a merchant gateway? You can write citations with D-STAR?

Just sayin'

Over D-Star DD, technically, yep. Legally, no.

Its is. ETSI TS 102 361

Wasted effort for a key that was cryptographically piss-poor to start with anyway because of its short length, and even worse, never changes. Fool

Um, I take it you're referring to SNMP MIBs?

snmpwalk it and see what you get.

And yet more "DVSI has everyone by the balls" proprietary vocoder shit.

mr.syntrx

Is IMBE available in one-off units, or is it a quantity only item?

mr.syntrx

Been busy lately. Work, travel for work (four countries so far), real life etc, so almost all of my projects have taken a back seat as a result.

Intercepting calls is illegal, cell mapping isn't.

USRP isn't needed - GNUradio can run off a discriminator tap (apprently) I'm having a hell of a time trying to get it to compile and run properly.. its a fairly big, complex, fragile thing by the looks of it... Yep, but a discriminator tap won't cut it for the projects I have in mind, which involve...

Long time no speak. Funny you should mention OP25 - I've been playing with it for about a week now - the wireshark extensions look quite useful. Next step is to build a dedicated linux machine and move it out of VMware. I was planning to buy a USRP a few weeks ago for other projects, right before t...

Uh, SDR still requires a great deal of hardware engineering. You don't just program the radio to tx from 30MHz to 900Mhz and off you go. While you probably know that, your post seems to imply it's just writing some code. Couldn't be further from the truth. Actually, with JTRS (Joint Tactical Radio ...

For the several grand per end they're asking, I don't see that many takers if it ever is released.

D-Star DD gateways require some real network faggotry that's best avoided if you can get away with it anyway.

mr.syntrx

The Feds have more redundancy built into their systems than even the most well-heeled Moto-tard could afford. I can assure you, use of an amateur-funded P25 repeater isn't even in their last-resort comms plan. If it got to that point, things would be so utterly fucked that playing radio would be th...

No way.

They're nice enough radios, but a Jedi or XTS will shit all over them in my experience.

Meh. It's only encrypted in the air interface, once its on the backbone anyone can access it if they wanted to

Yep, and Ki is pretty easy to find out anyway.

Just enforce IPSEC AH (without ESP etc) and be done with it. No obscured meaning per the rules, and your machines will drop any packet without a valid AH.

For what it's worth, ACMA (our FCC's) view is that it's not illegal by the letter of the law, but it's against the spirit of amateur radio because you can't get the specs for P25 without paying $$$$. (Well a government employee can get them for free, but everyone else has to pay.)

motorola_otaku wrote:Hmm, I would've thought that TETRA would win out over P25 in that part of the world.

Nah. Tait is their local radio company (gotta support local business after all), and P25 is already the winner on our side of the Tasman because of TETRA's piss poor low powered equipment.
