I find its not just as simple as 100 Watts to 300 Watts with SSB. I've been
using the TenTec Model 715 RF Clipper for a couple of years and find that
running my OMNI-VII at 100 Watts with 15 dB of RF clipping is just about as
good as running a small (SB-200/30L-1 type) amp. The bandwidth and shape of
the transmitted signal and the ears on the receiving end are in my mind more
important than my power. But if the RX and ears on the other end cannot
pull my 100W signals out, I can QSY or increase power to the Legal Limit of
the Titan 425.... I usually just QSY unless it’s a new one (VP8-S or FT8W).
73 es DX,

Serious question -- So... where does it stop ? If 200 watts makes a
100 watt rig just a bit better, why would a 300 watt amp not make that
200 watt rig just a bit better and find you even more DX ? And so on
down the slippery slope to megawatts, each little bit digging more DX
out than the previous bit?
How far down the slippery slope do we go before diminishing returns
cancels any marginal value from marginal additional power? What
circumstances and factors would force a different answer for different
operators?
(Serious question - not just making an argument. --
Personally, I find the maximum usable power is about 450-500
watts... any more and I don't make more contacts that I do
at that level, but should this not differ depending on antenna
type and deployment, and other factors such as external
noise levels, etc.??)

Happy Trails.

I agree totally. I have 100 W and know that any boost would have helped in
several cases over the years. I have missed considerable DX because I
could
not increase the power. there are many stations I have heard but could not
hear me due to QRM or QRN.
