IT sounds like you're having a problem with the radio overheating and shutting down. FT8 and other digital modes like it have VERY long duty cycles, so the radio gets hot very fast. If the cooling can't keep up, the radio shuts down to protect itself. Reduce your RF power and see if it helps. If

You will enjoy your KX1, as I have mine. I made thousands of QSO’s. If you can “zero-beat” within approximately 100 Hz this should be plenty close most of the time. I am a musician so I just adjusted the tone a bit above high C which is an octave above middle C. Actually a D is 587 Hz,

Re: [Elecraft] CW rise time setting

In the "good old days" key shaping was done simply by adding a capacitor to the key line or equivalent. That results in an exponential rise and/or fall time, which is not optimum, so the time constant had to be set pretty slow to avoid key clicks. Typically 5-10 ms. 10 ms results in "mushy"

You don't need to generate clicks to have a crisp CW tone. Elecraft uses a pretty much optimally shaped waveform (some version of a cosine function) and if I remember correctly the rise time is only about 2.5 msec, although I could be wrong about that last part. And while you may be careful not
