I concur. Thats why in CQ Contest Survey I voted to keep
the "useless" 5NN. I find that this precept is exactly what is
needed for successful QSOs. I haven't said it in as eloquent terms
as you, but after years of contesting its the phrase I look for,
especially when fatigued. It most definitely serves a useful
purpose. I think that by speeding up the 5NN actually reinforces
this fact and it increases intelligibility of the remainder of the
exchange. Besides, its shaves a miniscule amount of time off each Q.

CQ 160 METER CONTEST -- 1995
G'day from oz this is my score from last weekend.
First, a few special awards ....
Alligator Awards (All mouth and no ears) AB4XA, K0RW & IR4T
Awarded for not hearing my many many calls!!!
Fickle Finger of Fate Fast CQ's Award WA7FAB (I couldn't
even say victor K in the inter CQ pause - even first two
wouldn't fit let alone last two or all five characters).
Never did work him and still needed OR at the end!
Conditions were good with varying openings on each day.
Surprisingly good was the opening on Sunday about 40 minutes
before my sunset. The band later seemed to die as the daylight
was moving over the middle USA (the black hole I guess!)
it then picked up again as the grey path reached the west
coast. West coast is especially good because by then they
are running out of other W's to work!! Hence less QRM and
they can hear me; actually got some responses to my CQ's
around 1430 Sunday.
Call: VK5GN Country: Australia
Mode: SSB Category: Single Operator
QSO QSO PTS STATES COUNTRIES
Totals 52 486 25 5 = 14,580
Icom 765, Commander HF1250, 400W PEP
Vertical top loaded 76ft, 1000ft beveridge for receive.
Take a look at the contest times 2200 to 1600. My openings to
Europe occurr around 2000 to 2100. THIS IS NOT A WORLD WIDE
CONTEST!!!!!!! It is a US/Europe contest!! The closing time
seems to have a remarkable correlation with when the sun sets
on the "good ole you ess of aaa ". A true World Wide
would be 0000z to 2400z everyone gets one go at every possible
grey line. I am not very excited about this as we are too far
from everywhere to make anything like a major score. However,
as a matter of principle it should not be advertised as a
world wide contest.

Message-ID: <9503012242.AA06386 at netmail2.microsoft.com>
I'm trying to decide whether to build a twin 3-500Z amp that
meets my specs, or to buy a commercial one. What do you
think is the best twin 3-500Z amp on the market today?
Please email me directly. I'll do a quick summary next
