There are plenty of decent used linear amps out there if you want to go
that route, but if you think about it in dB, 1000W isn't _that_ much
more than 10W. Only a few S-units at the receiver.

Uhhhhh yeah it is. 1000w to 10 w is 20db ...

Right, it's only 20 dB. That is far less than the day to day propagation
variations. Only 3 1/3 S-units. Not much at all.

But..... 20dB can make all the difference in the world in being
heard.... and not being heard.

That's BS! If what you have stated is true, no one would run more than 10
watts. Believe me, 20 dB is _very_ noticeable.

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.

Roger

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