Actually, the US corporate tax rate being nearly double most other countries' tax rates has a lot more to do with outsourcing than free trade agreements.
MOTOTRBO is there a future?

Here is a new AOR scanner that does DMR, P25, D-Star, and NXDN: http://forums.radioreference.com/aor-receivers/297029-aor-ar-dv1-2.html#post2250020

That's the real expensive one?
Fixed that for you.
I would not call the Wide Band Receivers that AOR and the like put out "scanners".
It may do DMR and it may do P25 conventional but all info points to
the DV1 not being able to follow trunked radio systems.

And the real ugly one from the initial pics
To be honest if I won the lottery I would still pick one up for my collection.

Good catch Marshall! I just sped red it and threw up the link. :lol:

Can't be too hard to get into IF amateur Radio is already there and using it..?

CSI is saying they're going to have an SDR that does ALL of the digital protocols right down to phase ii, nxdn and even d-star. The website says price expected to be ~~$249 and available in november.
Hi,
With the added detail that, in November, the radio will be analog FM + DSTAR first, with subsequent firmware updates that will add the other digital modes.
No clear roadmap as to when those updates will come.
But at 249$ for *all digital modes*, let's stop waiting for radio scanners manufacturers to fill the need, CSI apparently will take care of it with these coming radios!

Putting a ham repeater up and developing, testing, and marketing a new DSP codec have about as little to do with each other as eating pizza and playing the trombone do. Amateur DMR uses the same off-the-shelf hardware as commercial DMR, we didn't reverse-engineer it ourselves.
now for the descramblers
Now when will some smart person come to our rescue and write a program to emulate the voice scramblers on Mototrbo and NXDN radios and hopefully ADP on P25.

It's a federal offense (in the U.S.) to monitor encrypted public safety communications, so it's very unlikely that anyone will try to come up with a way to decrypt any of these.

ADP was broken years ago. There is a presentation of decryption using GNURadio somewhere on YT.
Wouldn't recommend you get caught using it.....
Oh yea, for sure. I was just replying to "it's very unlikely that anyone will try to come up with a way to decrypt any of these.".
At this same time someone savvy enough to actually pull it off (it requires much more knowledge than an average hobbyist has) probably will be smart enough not to get caught.
Also no system, standard, encryption is 100% secure. The idea is to make it so hard to break into that it's impractical to even attempt it. But most of the attacks on the system don't even attempt to brute force the keys as this would take thousands of years if not more with the key lengths in use today. Most of the attacks I've read/watched talks about were exploits of unsecured information or legacy features.

Getting caught decrypting a received signal is so unlikely it's effectively moot. In fact, aside from telling people you're doing it, or committing some other known crime that merits a search warrant of your premises, the probability is somewhere around "getting struck by lightning while holding a winning lottery ticket".
It would be interesting if it were developed for research purposes only.
