K3/100 QRP Operation?

[Jim AB3CV]

I've currently got a K3/10 (#1210) and I'm considering adding the 100w amp
option. Once I do this how difficult is it to revert to QRP? Does the power
control make this easy?

Thanks

You can dial the power down at will. You can also disable the KPA3 with a menu choice, without physically removing it.

Jim, it is easy to turn down the power.  Just use the power control and you can set any power you want down to 100 mw.  The amp will kick out of the circuit when you set a power below 12 watts.  I have not tested the power reading very well, as I have no watt meters that I think are more accurate than the K3 watt meter, but it tracks pretty well with my Daiwa which is of totally un-known accuracy.  Go for it, you will like it!

Jim, it is quite easy, although cranking the knob became a bit tedious
so I assigned a macro to the PF1 button to set the power to 5 W and
another to PF2 to set it to 100 W.  It is a very quick and handy way for
me to jump to either extreme.

Other than the weight, which is a consideration for portable operation,
the PA does not hinder the K3's QRP capability.
