    This is interesting because Radio Activity have a DMR simulcast system and is evidently a Motorola Solutions Application Provider https://www.motorolasolutions.com/en...0-160-450.html

    We need 700 MHz DMR, so P25 Phase II can be pushed aside. In Canada, all new public safety allocations are 700 MHz (For TRSs). No DMR/700 = not an option, and is forcing people into the P25 scam.

    Smart move by JVC Kenwood. I saw Radio Activity's demo at IWCE this year. Very advanced and impressive product portfolio, multi-mode DMR/P25/NXDN/Analog network base radio modules. For a fraction of what competitor's charge for much less hardware and flexibility. RadioActivity has some large deployments around the world of that system. And yes, they support DMR simulcast, something MSI wants to keep out of NA.

    JVC Kenwood is making some strategic moves: first acquiring EFJ and now this acquisition. They are building a serious product/system portfolio and bringing some of the brighter minds in the business together.
    Your streaming makes me AES-256. Keep it up and you'll soon have nothing to listen to.

    This makes me really upset. It's all based on MSI's greed. Screw the customer and their needs', let's do what's BEST FOR US.

    It's my belief the people responsible for this type of draconian, greed-driven, sick thinking, should be rounded up sent packing. They want to keep technology out of our market so they can sell their OVERPRICED P25 PHASE II CRAP, at 8-10x the cost of DMR, when DMR does the exact same thing for much less.

    DMR vs. P25 Phase II:

    - DMR Tier III TDMA control channel supports CC on TS1, voice on TS2. No P25 Phase II TDMA control channel.

    - No P25 Phase II (TDMA) conventional support whatsoever.

    - P25 Phase II implementation requires an expensive trunking controller and associated costs.

    - DMR offers Tier II trunking solutions. No controller required. With the hidden "Extended LCP" option, you can expand up to 20 sites, with 16 timeslots per site.

    - P25 Phase I/Phase II offer no infrastructure protection. DMR (at least MSI's MOTOTRBO implementation) support RAS, which keeps bootleggers and eavesdroppers off. It functions similarly to P25 Radio Authentication.

    - Compared to P25 Phase I, DMR offers double the system capacity (TDMA), half the infrastructure costs, half the power consumption, half the rack space and less signal loss due to less multicoupling.

    - P25 Phase II and DMR both use AMBE+2 vocoder @ 2450bps for codec, and 1150bps for FEC. Audio should be identical.

    - P25 Phase II radios (APX) cost 5-10x more than MOTOTRBO 2.0 and 2.5 radios.

    - MSI refuses to sell (easily, anyway) AES-256 to NA TRBO customers. Want AES? Go APX/P25 Phase II. In EMEA market, this is not a problem.

    - MSI artificially degraded the audio in MOTOTRBO products, by means of over-driving the vocoder input. I identified and fixed this problem, and posted the fix here
    on this site. MSI was forced to implement the changes/corrections in firmware R02.50.05+, and sicked the DHS HSI on me for "criminal copyright infringement" as their way of thanking me.

    - MSI intentionally does not manufacture a 700 MHz DMR solution, because then public safety customers would have CHOICE.

    MSI, may all of you greedy, sub-human, filthy people, suffer catastrophic financial losses in the new year. You have no business steering this industry with your greed. CUSTOMERS COME FIRST, NOT YOUR PROFITS.

    Kenwood has really upped their game in the last ten years.

    Their radios are solid. I personally only use Kenwood for my personal use.

    I have:

    TK-8180H (400-470MHz)
    NX-700
    NX-200

    You can not pry these radios out of my hands.

    Kenwood was the first to offer multiple formats in the same radio, and multiple formats in a multiband set up(even if you do need to link single band units to a common control head).

    Being able to have NXDN, DMR AND P25 phase 1&2 Plus multiple bands in their portables would be good as well.

    If they offer a V/U1/700/800MHz multiband/Multi protocol portable as competition to the APX8000, they will likely be hammering nails in MSIs coffin.

    If they offer P25 phase 1&2 Plus DMR tier 3 in the NX-5xxxx series they will steal even more market share.

    Kenwood is listening to what the market needs, and are making strategic moves to be able to deliver these needs to its customers. They are adapting to the changing landscape. MSI is not.

    I 100% agree. They make a solid radio.

    In the NX-5K series you can do two of the three formats in one radio.
    You can however, link three radio decks together and get NXDN, DMR, & P25 phase I or II.
    Kind of an expensive way to do it but it gets the job done.
    Now if they offered all three options in a single deck, that would be a game changer.

    I don't entirely agree.
    Two reasons:
    1) Customers and dealers have been asking Kenwood for the three radio format in a single desk since they first announced the NX-5k series.
    All we keep hearing from Kenwood is "we are looking into it" with no other mentions of a beta or additional feedback.
    2) The other big gripe is the way they are doing their upgrades. They've taken a page from MSI's book about entitlement keys.
    "Here's a base radio for $400. Oh, you want to program the radio with software, buy the key for $200. You need more channels? $400. P25 trunking? $600. DMR? $200."

    Keys and key management is complete bullshit the way they are doing it. Case in point, heaven forbid your PC that you have the software installed on ever crashes. It is a complete pain in the ass to try to get Kenwood to de-authorize a key so you can use it again on the new computer. (This was a dealer mind you that had this happen.) You've either got two choices, wait six months while they play 200 questions about de-authorizing a key, or spend another ~$400 to get a new key. Oh and don't ever lose the upgrade keys.
    Such utter nonsense.

    This is one reason that I havent upgraded to the NX-5K yet. Once they pull their heads out of their ass and fix that portion, then I would upgrade.
    Poor planning leads to poor results-->Welcome to OKWIN.

    Not gonna lie, I've been very tempted to flip my XPR7550 and get a NX5300. Having P25 and DMR in one radio would be the bomb.

    The only thing that turns me off is the ergonomics... it just looks and feels like a scanner to me. The software/entitlement nonsense that the above poster mentioned is a negative, too... not to mention that KPG-D1N is easily the worst piece of programming software they've ever turned out.

    As you know from our convos outside of here, I've just spent several weeks fighting with APX CPS, A25 CPS, and KPG-D1 to build brand new codeplugs for a P25 system. Ironically APX CPS was the easiest to get the job done. KPG-D1 wasn't horrible, but the learning curve of someone like me who's used to (a) KPG-89 and (2) APX/A25 CPS meant it was a bit of a chore, and to boot, the 90-120 seconds that KPG-D1 takes to process the codeplug after reading the radio or loading from disk (even on a brand new computer) is infuriating. (A25 CPS? Don't get me started.)

    I've learned how to use KPG-D1 fairly well, through almost constant use of the help file and one or two advice requests. I don't mind it that much. I shouldn't have to plan to do something else for a few minutes after I press 'read from radio' though. I'd expect that from 1990s computing, not new software on a machine with a 3GHz i7 and 12GB of RAM.

    The radio itself... the NX-5400 is growing on me and my crews. We've used TK-2180/3180s for several years (and before that, MT2000s/HT750s/MTS2000s) and everybody loves the new radios. Of course, a lot of it may have to do with the better feature set in modern radios over & above any of these older ones (none of our older radios were "model 3"/"tier 3", with full menu options etc), but the Kenwood price for radios is a hell of a lot better than the Moto price.

    This makes me happy. I've sold my Motorola XPR5550s and replaced with NX5800 and am very impressed with the radios.

    Radio activity make some great products especially for the smaller systems.

    Here is a local VHF DMR Tier II repeater at a site I manage which is backhauled via UHF DMR link working in point-to-point mode. So in the rack are two otherwise independent Kairos units. Also visible is an RFI duplexer and partly connected Cisco switch used for connection and monitoring:

    Kairos is a old Greek word meaning the right, critical, or opportune moment. Something related to time so possibly a good name for a TDMA product. Here a shot of the repeater module out of the rack (from the maker's web site):

    Not certain I dig the packaging but they really do work well. Rated at 25W but in this install it is running at more like 12W because of the high antenna gain and because the user radios are all handheld.

    I've gotten information on Hytera's DS-6310 simulcast and Radio Activity solution is about 1/3 the cost for a relatively simple 3 site system. Amazing

    With Tier 3 subscribers from Tait, Hytera, and eventually Kenwood, I think we will see some seriously good competition to MSI

    The backhaul options with the Kairos is great, I feel like backhaul is totally overlooked in the commercial market, relying on public ISP is pathetic but not everyone has/can afford microwave and license free i.e. Ubiquiti air fiber is limited.

    There are a few VHF DMR simulcast systems in my area using Radio Activity hardware and they all seem to work quite well. A few IPSC systems have been swapped out as well as there was constant issues with the roaming between sites.
