Don't forget to factor in ionospheric heating due to RF which will increase
the received signal strength even more. Therefore a 10 db increase in
transmitted power will result in more than a 10 db increase in received
signal, depending on path, frequency, and how you tightly you are gripping
the microphonium.

But I won't HARP on this any further ..... ;-)

If one calls 10 times in a pile up to work the DX with 100 watts, and once
with a kW, the product of power times time is equal. So from a ecological
viewpoint, the two are theoretically equal, provided the overall
efficiencies are the same. But the overall efficiency for the amp plus
transceiver is likely to be higher, since the overhead of the low power
stages etc is a smaller percentage.
