Very nice to see this product! But, when you go thru their 65 page presentation, a few things became apparent to me:
1. It appears that their encryption involves back-to-back XTS3000's, and the double vocoding syndrome (notice they mention no secure transparent operation is possible, and they discuss Encryption ON/OFF, so this looks like a back-to-back arrangement, and not a "true" digital P25 repeater).
2. There is no ASTRO modem, thus no DIU3000 capabilities, thus no dispatch tie-in, encryption from the dispatch point, etc.
3. It better be a ton less $'s than the PDR-3500 to be worhtwhile.
Nevertheless, it's very interesting.
BTW, this is another GREAT example of copying being flattering to the person copied! Notice how the underlying RF section (the heart of any repeater!) is the XTS3000, just like Global Wolfsberg does with their P2000. I love the way their slide show was looking pretty professional, until I came to the slide discussing Maintenance. Then, they say for the main RF unit (which is the XTS 3000), you "simply place the board into their specially supplied XTS3000 case, and send it in to Motorola!" (Like you have to fool Motorola that it is a "real" XTS3000, as opposed to being honest and sending in just the board). At this point, their product started feeling like a Rube Goldberg set-up.
Again, its neat to see competition in the P25 marketpalce, but you'd think these guys (including Global Wolfsberg) would do like Kenwood and ICOM and build their own P25 radio(s). This way, you wouldn't have to equivocate with Motorola when you send it in for repair!
