    Most of the The "Flex" radios rely upon a computer, do they not? And when (not if, but WHEN) Microshaft goes beyond Windoze 10, will it still be supported? Or ANY operating system, (Windoze, LINUX, etc.) have support, and just WHO will support it, and for how long? I still use transceivers built even before computers were commonplace (DOS 3.2 or earlier come to mind) that would be mere doorstops if they relied on a computer, yet they are still totally functional. Can THAT be said for the FLEX offerings 10 or 20 years down the road?

    Using a flex 30 years from now may be a challenge without a 30 yr old PC. . . if I were to box up my 7610 and stow it in the attic for the next 30 years, my grandson could pull it out, plug it in, and it would work! Just like my grandpa's hallicrafters receiver that languished in his garage for 30 years before i found it, plugged it in, and got hooked on short wave. Good luck doing the same with a flex.

    As a dual-K3 SO2R op I would like to know that too :) I will not be able to afford two K4's!

    I notice there is only one "Key Out" jack, so it looks like the K4 can't easily be integrated into most current SO2R stations which have two separate amplifiers.

    14 Vdc amps can be modestly good. For example, take the currently manufactured Kenwood TS-590SG:

    Third-order intermodulation distortion (IMD): 100 W PEP, 3rd/5th/7th/9th order:
    –31/–38/–48/–55 dBc (worst case, 10 m);
    –42/–38/–48/–58 dBc (HF, typical);
    –41/–38/–50/<–60 dBc (50 MHz).

    Those are good numbers. :)

    Im glad you returned to reality at the end of that statement:D There are several portable friendly radios already on the market and I doubt the K4 would be very rugged in many of those environments.

    I do have a Maestro that doesn't depend on my computer. :) (though it is a computer itself)

    That said, it's a very real question.

    I think that means it's available as a kit the way the K3 was available as a kit....meaning not really a kit at all, just a little assembly.

    To each their own, of course :) I'm a huge fan of "top of the line," from 20 years ago...

    I still have the IC781 I bought in the early 90s and couldn’t agree more.

    I recently added a TS-950SDX to my collection. Superb radio and a joy to operate with. It was so sad when Kenwood got rid of the fluorescent displays.
