I think it's more complicated than that. If you look at the maximum
gain figures for your basic vertical or dipole and then look at the
figures for stacked yagis, you're not going to find anything beyond
the level of 10 or so dB, unless you get really into BIG arrays.
100 watts to 1 kW is 10 dB. Going to 1500 watts is 12 dB. So, that's
probably a wash.
A bigger variance is the ANGLES. You may have huge beam with 10 dBd
max gain way high in the air, but if the angle offered by propagation
is right in the 30 dB null of the antenna, then you're better off
with the low dipole. That will make a 20 dB difference.
You can't create favorable propagation with an amplifier, no matter
how big.

You don't know that for sure.

Perhaps some of these guys, like you and Hal, got bored, turned on
the amp and are sending in checklogs.
In any case, if there's rampant cheating, then a well-placed DQ or
two should have a positive effect. It sounds better to me than
ruining the contest by allowing HP.

That makes some sense to me. Guys who have built stations that are
competitive in domestic contests (SS) do well in the NAQP. That
doesn't mean they are cheating.

You don't. You have your choice. You can build your own superstation,
or you can try to get invited to guest op at a superstation, or your
can try to do the best you can with the station you have, and take
delight in beating out guys who have much more hardware than you.

I spend most of my contest time running LP. About the only time I use
my wimpy AL-80A is in RTTY contests, and even then I only run about
400-500 watts out. I can't even use the amp on 160m or 80m. Trust me,
I know about low power.
NAQP is a lot more fun for me, because I don't have to slug it out
between the kW stations. SS is a lot tougher. It's much more
difficult to try to hammer out a clear frequency with kWs on either
side. This is ESPECIALLY true on phone. No so much on CW.
If the rules were changed to allow HP, scores might be higher, but
the fun factor would disappear.
