Does KPA1500 have these KPA500 characteristics?

Re: Too Much Power

Good point about "weak signal". Really refers to receiving and not
transmitting.

Example: eme operators are so dense in population in EU they have
mutually agreed to transmit during the same sequence in order to
minimize interference.

New: digital modes use on HF *should* augment operating during poor
propagation (when signals are received weakly). During normal *good*
prop one should lower power accordingly to what is sufficient.

HFer's lower their power - huh? That's a joke, right?

Joe should build in a random number generator that generates a random
between 1 and 20, then apply that number to signal strengths by adding a
+ in front of it. If you are stronger than the random number, WSJT-X
drops your call from the list...

A few nights ago, with my hex beam literally on the ground (for adjustments), I worked India on 20 meter FT8 using 50 watts. I jumped for joy when that guy came back through the “pileup” to my call! 8720 miles! My report wasn’t stellar, but who cares?

Jack,

I just assumed you were throwing in an extra 8 db for the difference between a beam and a wire dipole.

Let me correct myself before others do. Its a 12db difference. And I will rib Bill about it. Still, to the west and north he has very high hills/mountains that block the RF path. Makes me wonder if he was using reverse path for the QSOs.
