[K3] power output

[mikerodgerske5gbc]

My k3/10 puts out slightly more. Sometimes 9 or 9.5 watts equals 10.
Since that drives the 100w pa I would expect a greater amount at 100w.
I just figured it had to do with compression on ssb. Try it with zero compression. Also advise how much more it's putting out.

Hi Mike,

Thanks for the reply.  I've just done some more tests here into a
dummy load.

Set for 100W output, the K3's meter  shows me exactly that on CW.
On SSB I can get as much as two extra bars above the 100W mark.
If I turn compression off this happens considerably less often,
but the meter will still bounce up there occasionally.

Having perused the manual a bit more, there is a note on the
bottom of page 28 which suggests that voice power and CW power
are not the same; presumably the power the user requests is
considered in 'CW' terms, even in voice modes; in which case
fiddling with CONFIG:TXG VCE should sort things out.

So in summary it seems I led myself astray by imagining that
there is more feedback from the meter to the PA than is, in fact,
the case; hence wondering why the K3 was telling me it was giving
me 120W when I asked for 100.

73,
