Comments:

By mid-September it looked like there would be a one-week break in harvest
exactly centered on the WW RTTY weekend.  I planned to do a single-op as P49X
when Glenn, W6OTC, became available and interested in joining me for a
multi-op.  Moreover, his wife Joan hadn’t been to Aruba and asked to come
along.  That was a no-brainer for me and it turned out far better than I even
imagined … Joan prepared and delivered three exquisite meals each day right
to our operating positions!  In between, there was always a fresh supply of
healthy snacks and drinks.  Such a luxury I’ve never experienced during a
contest.  Now I understand why some people advocate that such dietary support
puts single ops into the Assisted category.   ;>)

With two operators, Multi-Single is the obvious choice over Multi-Two, but we
thought it would be more fun for each op to be able to run as much as possible.
 I also reasoned that it was a simple extension to my original SO2R
planâ€"we’d just have one op on each radio and now have the opportunity to
fully exploit SO2V to keep the bandmap cleared out while running on the same
band.  Finally, one op could take a break while the other ran SO2R, but now
unconstrained by the one-signal-at-a-time rule.  The disadvantage, of course,
is that we were not capitalizing on the ability to use multiple operators for
stamina relief.  And, my alertness was further compromised by Joan delivering
wine with some of the meals!

This variation of the Multi-Two category was a lot of fun and we are happy with
the results as compared to the 4-operator Multi-Two we did last year.  Our
numbers were nearly identical except for a 500-QSO shortfall on 20 meters,
which we believe to be self-inflicted.

Like the 2011 CQ WW RTTY Contest, solar conditions peaked nicely again, though
at a lower level.  10 and 15 were open worldwide beyond daylight hours.  20 was
relegated to a nighttime-only band along with 40, while 80 meters was a struggle
for QSOs, let alone mults.  However, we experienced hollow, watery signals for
much of Friday night and early Saturday.  Signals on all bands were difficult
to decode despite having good signal strength.

We fell behind last year’s QSO total by 350 on Friday night, then reduced the
deficit to 250 when 10 and 15 exploded to life Saturday morning.  But, we lost
ground again Saturday night on 20 meters.  Our run rates plummeted during the
last 4 hours when it appeared that participation decreased while signal
strengths held.  On the other hand, there was no CME event that shut down all
bands for 90 minutes like it did on Sunday morning last year.

The second-harmonic from the low end of 40 inhibited copy of weaker 20 meter
signals, significantly lowering the rate on 20.  In retrospect, we could have
operated higher on 40 and decreased the RFI.  Also, we unfortunately determined
after the contest that the interference was less when we swapped the radio
assignments for the two bands.  Inter-station RFI abatement remains a top
priority for this station.  I installed high power bandpass filters on each
band but initial measurements don’t show the expected improvement.  The long
term plan is to also add a high power combiner and three StackMatches so that
the C31 is available simultaneously on the three high bands with the
station’s monobanders.

By running only one radio most of the weekend, I had the bandwidth to hone my
SO2V skills.  It was relatively easy to keep the bandmap worked out at run
rates below 100/hour.  The priority is to minimize delays on either the run
sequencing or in responding to the S&P QSO.  And, it is easy to injure yourself
by transmitting the wrong message on the other VFO.

Another gratifying aspect of the weekend was the noticeably larger number of
quality tail-enders.  I’m not referring to endless callers while a QSO is in
progress, but rather the careful timing of a single instance of a callsign. 
And, this worked nicely in both directions.  That is, there were several
stations who picked up my tail-end and worked me next without the CQ/pileup
phase and without missing a beat.  One that comes to mind is WA5ZUP.  Those
were a lot of fun.

I hope more people are catching on that I try to work callers in the order that
they first appear.  When I sense there may be more than one caller to my CQ, I
hesitate just a bit after getting the first callsign, in order to see if I can
get more callsigns.  The record this weekend was a 6-deep stack.  1- and 2-deep
instances were common.  Eliminating all those CQ/pileup cycles really speeds
things up.

The Elecraft PR10 10-meter preamps were invaluable.  They enabled us to decode
extremely weak signals on a very quiet band.

Thanks again to all the participants, especially those who worked us and we
greatly appreciate the band-moves!    Also to John, P40L (W6LD), and Andy, P49Y
(AE6Y,) for use of the cottage station.  Special thanks to our live-in gourmet
chef, Joan Vinson.  The pre-contest log of 1300 QSOs will be on LotW tomorrow
and the contest log on 16 October.
