Sure, it's very noticeable. But, as someone running half a watt CW
these days, I can say that it's not everything.

Agreed , QRP can be very cool.

I am finding similar results with PSK and helshreiber on less than 50 watts
with regular European contacts.

And yes, you can make bunches of CW contacts with a single 6L6.

The problem is a ham linear will not deliver 1000 watts carrier
power on AM. It would have to be rated for 4kW to do so.
PEP on AM is at least 4X carrier.

The current power limit for AM is 1500 watts PEP. This
means a carrier output of 375 watts. Easily obtainable
with the proper linear amp.

Thanks for pointing this out. Unlike SSB, the legal limit for AM has been
reduced from what it had previously been.

My point was, forget 10 or 20 dB improvement over a 40 signal.

Pete

I'll buy that. But, time and time again when on 40 meters SSB, as an
example, and running 100 watts, when the receiving station tells me that he
is having readability problems with my signal, then when I switch on the
Drake L-4B, the user almost always reports a significant improvement in both
received signal strength and readability. Going from 100 watts to 1000 watts
is 10 dB. Going from 10 watts to 1000 watts would be even more dramatic.

I still regard the statement that a 20 dB increase in signal strength is
"Not much at all" as pure Tier Scheiss.

Right. But any linear rated for 5KW carrier will have no problem.
There are some out there.
