    Pretty close. Of course, telegraph technology was a wireline service that worked with sounder clicks instead of mouse clicks. No RF needed. It could (and did) work in multicast architectures.

    So, why not take FT8 to the next level with RF hotspot devices? Anyone get a SharkRF Hotspot2 for the holidays? Apply the same concept to FT8. Use a tiny hotspot device connected from a 100 milliwatt SDR transceiver and say you're making "RF QSOs" to distant lands for DXCC. No need to even worry about -24 dB SNR contacts. No antenna restrictions. One of those Miracle Whips is all that's needed -- indoors!

    Anyone using Yaesu System Fusion or DSTAR likely understands. Just let the Internet connect to thousands of other FT8-enabled SharkRF hotspots direct via the Internet backbone or through medium-power HF/VHF/UHF RF nodes to do all the heavy lifting. It's just a matter of time. What's left are just...mouse clicks!

    WHERE CAN I FIND A INEXPENSIVE RADIO THAT DOES USB. PLEASE DON'T SAY "BUILD ONE"

    Everyone takes a different approach I prefer to use my search engine on the computer where I find page after page of information that, for the most part, answers my questions.

    Maybe you should recalculate after adding all the Olivia speeds together. Speed often changes mid QSO depending on conditions.

    Not at all. For one thing, there is a heck of a lot more to working FT8, JS8, or PSK31 than click-click-click. Successfully anyway. Who should I try to work right now? Which band? Call CQ? Wait for him to call CQ? Tail-end the station he is working? How much power should I be using? And on and on...just like phone or CW. :)

    And I wouldn't worry about CW and phone going away. As soon as conditions improve and amateurs with modest stations can do better with the trad modes, many if not most will go back to them (if they stopped using them, which most digital ops haven't).

    You can often find a used ssb xcvr for 400 or less at a hamfest.

    Haha! No, I would not suggest building one. You'll just have to "keep your eyes out". Watch the Swapmeet section here at QRZ. But I would recommend keeping it pretty modern. An Icom 718 or Yaesu FT-450D would be the "low end entry point" at around $500 - $600 Anything cheaper (meaning OLDER!) may be more of a challenge to get set up for digital modes with.

    You'll also need an interface (SignaLink is a good one - I've used one for years) and of course a computer, which can be practically anything as long as it runs well, and has a clock-sync program (Dimension4). WSJT-X can run on Mac, XP, Win7, Win8, Win10, and Linux.

    Good luck!

    I like Olivia as well, 500/8 on 14.072, however, the DX I find more on JS8, as it has about 11db advantage, (-24db for JS8 while -13dB decoding abilities for Olivia) and for my favorite flavor for Olivia (500/8) the bandwidth is 10 times wide than JS8 (50hz). add to that, the program for JS8 is a fix platform, so the pool of ham operators all in one spectrum, whereas Olivia there is a wide variation of flavors, and choice of frequencies, which you would think is a good thing but the reality it is to scattered (Also Like 30wpm, on Olivia!)

    C U on the bands!

    re: "Pretty close. Of course, telegraph technology was a wireline service that worked with sounder clicks instead of mouse clicks. No RF needed."

    AND - before that, semaphore (flag waving) and signal fires ... the "wigwag" method ...

    The US Army used to have manned posts out west doing signal relay too.

    Would one of these qualify?

    Order µBITX with Raduino for $129 with free shipping ($10 extra for DHL Shipping)

    http://www.hfsignals.com/

    I think these are a "minimal" kit:

    Build the µBITX transceiver in an evening. A general coverage, 10 watts HF SSB/CW transceiver kit with features you NEED for operating ease, convenience and versatility. It works from 3 MHz to 30 MHz, with up to 10 watts on SSB and CW, with a very sensitive receiver. It features digital tuning, dual VFOs, RIT, CW Keyer and more.
