[Elecraft] KPA100 recommended max power for digital modes?

[Gerald Manthey]

I run 25 watts on my K3. I adjusted it by watching my peaks on a scope. At
25 watts and my alc set I have a clean signal. There are those that splat
more power and we all see them in the waterfall. 25 watts will work the
world on PSK.
Just my observations and my .02 cents.
