    So long as you think 1890 is what's intended. We've technologically advanced a bit since then.

    Sure, you can PTT and voice or Morse code just as we did 100 years ago, or you can let go of your nostalgia and learn to evolve and adapt.

    But some prefer to fall behind and bitch about how the bands are dead (using your preferred mode).

    Go where the action is sir, or you'll be rather lonely in your angst.

    Since you said it Phil, I assume you have. Where's the specific profit in this?

    Excellent short article outlining the evolution of internet digital radio. Thank you for authoring.

    I thought common sense would prevail and people would understand i was talking about internet linked operations, i am sorry i did not make my point more understandable. W4NNF you seem to have focused on the word Ham, you have missed the point the key word is Radio. Internet linked operations is not Radio, i will no doubt be told that RF is involved but when i put todays lunch in the microwave RF will also be involved, by some peoples logic i could assume using my microwave is Ham radio. I dont know about the USA but here in England not many years ago the Radio was called The Wireless, i guess it was called the wireless for a reason.

    The wireless radio , i grew up with it and listened to the the Lone ranger and many old programs.
    On my transceiver i talk to people, hello is anybody home .

    The only angst I see is your bitching and the only dead bands are due to propagation, so there is plenty of activity on the bands when propagation is favorable, so don't try to tell me what I don't know.

    In my last job I designed avionics weather radar and avionics SDR transceivers up to 1 kW, so don't tell me I am behind the technology curve. I also occasionally work PSK31 digital.

    As far as the money goes, read the original text in the post:

    "...In 2012 or so, Yaesu introduced Wires which is much like Echolink and AllStar. There are servers with rooms, not unlike chat rooms, where you connect a node to and in turn your radio...."

    "...Two years later, ICOM started developing D-STAR hardware which resulted in actual physical radios less than a year later. Today you can get D-STAR hardware from ICOM, Kenwood and FlexRadio Systems..."

    ..."For many years D-STAR and DMR-MARC, the DMR Motorola Amateur Radio Club World Wide Network, were the main digital radio systems around in amateur radio. That changed in 2013 when Yaesu introduced System Fusion..."

    Yes, it all sounds very geeky and tekky but is it really ARS?

    I think you have that backwards. For linked systems, utilizing the Internet extends amateur radio. Pre-internet, linked repeater systems needed RF links to tie them together, or private wireline. This can still be done, but is very expensive to do and maintain.

    The internet is a cheap way of tying machines together, whether they be analog (via VoIp based systems like IRLP, Echolink, Allstar), or digital (D-STar, DMR, Fusion, etc.) NONE of these networks REQUIRE the Internet, and there are many digital linked systems built entirely on a private backbone. I happen to use one here in Colorado Springs - a linked DMR system covering a good part of the state as well as into Wyoming and New Mexico. Private microwave. Expensive.

    If the FCC requires an amateur radio license to operate it, I'd say that it's amateur radio. Experimentation and enjoyment are my goals with amateur radio.

    To the OP - good summary!

    Here in the UK if you RX or TX no matter if its amateur, broadcasting, aeronautical, maritime and so on you are governed by the rules set out in the WIRELESS Telegraphy act, i assummed from your comment that you felt that you only listen to a wireless,hello is anybody home .

    Though I've not been involved in DMR a long time, I have already begun appreciating its way of making my morning walk around the neighborhood more interesting. My IC-7300 won't fit in my back pocket for such walks, but my MD380 nestles nicely in my hand while I'm listening to others and occasionally throwing in my two cents' worth.

    Anytime something changes, there will be folks who complain that "amateur radio just died" or some such rubbish. I've seen a few of those changes over the past 40 years and, guess what, amateur radio continues to percolate right along.

    Something to Cogitate upon... If we look at what the generally accepted definition of radio "the transmission and reception of electromagnetic waves of radio frequency", one must logically conclude that a transmission that propagates over a medium other than "the ether" is not truly radio. If something is psychically connected between the sender and receiver (telegraph wires) , fiber optic cable (photons not electrons) etc. it is by definition not radio. If a transmission is to truly be classified as a radio transmission in its purest form it must be wireless. If you are using the internet (a network) as part of the link to reach a wireless TX then the internet network is a routed network relay point that in my opinion is not different than a repeater or satellite hop. If communication is strictly VOIP or packets on a network it is not radio. It can be related to a radio activity such as ham radio but, it cannot stand alone as Ham radio. With respect to contesting and not allowing terrestrial relays; I think this is correct. So as we ply our craft in the spirit of Tesla, Faraday, Marconi and others; let us excite our transmissions with what ever modulation scheme we have now or dream up in the future and "Work the World with Wireless!"
