I don't use that mode and generally run no more than 40 watts on PSK31 with the K3.

But this statement below "The K3/100 has two fans. The KX3 has no fans. Apples and oranges." made me wonder if fan failure could be an issue with the K3/100 -- and one which might affect those running less than 100 Watts.

Just how many people are running high power on low power modes like jt65?

I work the world with 10 watts.

    I have so much ringing in my deaf ear I
    never hear the fans!

        Hi Steve,

        The K3/100 has two fans. The KX3 has no
        fans. Apples and oranges.

        I ran my K3 on 30 meters RTTY at 100
        watts for 2 hours non-stop as an ARRL
        centennial station and had no problem.
        The fan just ramps up to a higher
        speed.

        I've also run JT65-HF on 6 meters at 100
        watts with no visible problem but
        of course it's one minute on, one minute
        off.

        73,
