Ham Radio Now - Episode 7: DMR Digital Mobile Radio (Pre-Yaesu Edition)

Not everyone is waiting for Yaesu to introduce their line of digital voice VHF/UHF equipment. A few thousand hams are already using the DMR protocol with bus…

    Well, regardless if it’s P25, iDas, DMR, DStar…. Analog has a big place
    in communications. If we were to lose the internet (since everything
    Digital is routed through the net), we need to be cautious on how much
    Digital we use. Sure, use Digital to your hearts content, but make damn
    sure you keep Analog handy, and practice it, too!!

    Digital doesn’t /have/ to be routed over the Internet. It’s more than
    possible to have an offline repeater exactly like analog. For big linked
    systems it could even be linked over RF with the right setup.

    LinuxManUK ,I do not see anyone forced at gun point to buy Icom’s repeaters
    . People build their own d-star repeaters while others buy them from Icom
    .. I built my own hotspot . I love d-star . It shows that you have never
    tried it or can not get along with anyone . Analog is dead . Wires from
    Yaesu failed .Lets see what happens to these cheap looking yaesu radios .

    Dan, to answer your questions, the raw data throughput with a Mototrbo
    product is 4800 bps as I am told, however the true data rate is dependant
    on the application, error checking and overhead needed for the data
    application you are running.hope this helps

    Nice video, but I would request that you let your guest speak. It seems as
    though you interrupted often and droned on quite a bit when I was waiting
    to hear a complete thought from the expert…respectfully submitted.

    Who wants or needs Motorola to get ‘into’ the Amateur market ? There’s
    plenty of Motorola stuff about already, most of my shack is Motorola. AF
    quality on FDMA P25 is good, so on 70cms, a noisy FM signal is a solid
    armchair copy P25 signal. its a no brainer. error correction seems better &
    faster to re-synch than d-star, esp in fringe areas & better on the ears
    than noisy FM, you’ll only become a convert by using the gear 🙂 get some
    Motorola digi gear and point yer yagi up to Lancashire Daz !

    FFS ! stop using QRZ when calling CQ…. QRZ means: “who is calling calling
    me” and ” you are called by”.. nothing else..

    This sounds much better than the d-star toys.. maybe because motorola and
    others realize that the microphone is essential, wich Icom apparently do
    not… (made in china and sounds like shit, really)

    Thank you for a nice video!

    12.5khz has arrived in UK on ham VHF and PMR.for a while now.
    On ham bands VHF,its hasnt really been worth it and has caused a lot of
    confusion and inter-operability problems in my area not sure in other
    places of UK.
    DMR moto radios sound lot better than D-star and esp when using them in
    mobile ops.Nice video

    I can foresee a lot of potential for several data enabled options on ham
    radios using both d-star and mototrbo, etc. For eg. it’d be awesome if
    your out working in the yard, or on field day, and you need to e-mail a
    friend, be able to send it out via your hand-held. Check your e-mail
    possibly, send text messages to cell phone, receive text messages, lots of
    cool uses out there. But the biggest thing about it is, none of that makes
    any difference if nobody uses it! Lots of repeaters used to use phone
    patch and other features, they killed them all due to abuse mainly,
    likewise, don’t expect many repeaters to support all the fun features.

    The Motorola representative was a gentleman with the patience of a Saint.
    He was entirely justified in just walking out, only his professionalism can
    have stopped him. The interviewing was intrusive, objectionable, ill
    mannered, amateurish and arrogant.
    I don’t know if there’s a training scheme for interviewers to learn their
    craft, but presumably he hs either never found one, or bothered to enrol.
    Thank you Mr. Motorola, I learnt a lot, but if you ever contemplate going
    through that again, bring some duct tape 🙂 I KNOW you could have told me a
    lot more, given the chance.

    I have only just watched this video and found it very very frustrating, the
    guy doing the interview needs a serious lesson on keeping his big mouth
    shut and allow the interviewee to say his bit, I have never heard someone
    love the sound of his own voice as much as this interviewer does.

    the real problem with digital mode is that each manufacture, makes his own
    way (dstar, yaesu, motorola,etc..), i think that would be better only one
    and of course all equipment is very expensive (repeaters) to buy by the
    clubs.

    This sounds like the grandchild of the REACT system used on CB radio during
    the 60s- 70s. If so it definitely has possibilities for being a great
    service to cival preparedness and community service during all kinds of
    applications both in group and throughout the community.

    EMP…. if you are in the EMP area YOUR ARE TOAST! The EMP radius DOES NOT
    extend past the blast zone of the weapon that causes it. The worst part of
    it is the power surge that you may get in a power line….

    AmRRON Rebroadcasting Station “Black Echo Program”
    http://www.amrron.com/communications-resources/rebroadcast-stations/

    Radio Free Redoubt Rebroadcasting Station “Black Echo Program”
    http://www.radiofreeredoubt.com/communications/rfr-rebroadcasting-stations/

    During the spring of 2014, the Radio Free Redoubt Rebroadcasting Station
    Program will be formalized and expanded. A “Black Echo” rebroadcasting
    station is a Redoubter who has invested in a commercial transmitter on the
    FM or AM frequencies who then air, or rebroadcast, the Radio Free Redoubt
    podcast in their local neighborhoods and communities. In an information
    black-out situation, when commercial broadcasting may be spurious or
    non-existent, “Black Echo” stations will act as critical sources of
    pertinent information and reassurance to their communities on the FM and AM
    dials.

    For those interested in becoming involved as a “Black Echo” station,
    emphasis should be placed on acquiring low power AM/FM equipment which can
    be switched between from low power (500mw) to high power (30 Watts of
    output power). The capability to increase power will allow the station
    operator to reach listeners several miles away during an emergency /
    TEOTWAWKI situation.

    Things you might expect to hear from a Black Echo Rebroadcasting Station:
    Live Streaming Radio Free Redoubt broadcasts (During grid-up situations)
    Previously-downloaded RFR podcasts, as well as, other patriot centered
    podcasts and audio files
    Live AmRRON Nets Radio Traffic
    Live Commentary & Public Service Announcements from RFR Rebroadcast Station
    Operators

    NOTE: Please remember, it is not legal in times of non-emergency to
    broadcast beyond Part 15 FCC rules.
