W5WZ visits K8AZ

2011 CQ WW SSB

M/S High Power


How did this happen 2010 cw ww ssb w5wz m m hp team finishes 11 th usa
How did this happen?2010 CW WW SSB – W5WZ M/M HP team finishes 11th USA


How did this happen cont d
How did this happen? (cont’d)

  • 2010 CW WW SSB – W5WZ M/M HP team finishes 11th USA

    • W5WZ & team wants to improve

    • Seeking a top ten (in the box) finish

  • W5WZ contacts K3LR for tips to improve

  • K3LR schedules phone call with W5WZ


K3lr comments are surprising
K3LR comments are surprising

  • Why do you want to do M/M?

    • Fun

    • Competition

    • Technical advancement

  • Have you considered M/S or M/2?

  • Suggest you take sabbatical this year

    • Visit / operate another station

    • Learn, go home and improve


The invitation comes
The invitation comes

  • K8AZ calls the next night

    • Long time friend of K3LR

    • Team member K8MR is contest mentor to K3LR

  • W5WZ accepts

  • W5WZ notifies W5WZ M/M team of cancelled event for 2011

  • Plans begin to take shape to travel to Ohio


K8az sends homework
K8AZ sends homework

  • Learn Win-Test (logging software)

  • Listen to bands – for propagation

  • Be familiar with FT1000MP, K3 operation

  • Be familiar with K8AZ antenna farm layout

    • K8AZ sent pictures, written descriptions

    • Aerial photos of tower orientations

  • Learn the contest rules all of them!


Most important assignment
Most important assignment

  • Just a well rested run operator.

  • Oops!

    • Scheduled to depart SHPT Friday @ 6am. (aircraft mechanical problems, late flight crew, we departed 8am. Missed plane in Dallas, rerouted to Chicago, near-miss connection to CLE, and lost luggage)

    • Finally leave CLE airport at 4pm

    • Contest starts at 8pm


Flight delays rerouted to o hare
Flight delays, rerouted to O’Hare

  • I’d always wanted to visit Chicago!


Airport shuttle via k8mr

  • Nice late afternoon lunch and tour of K8MR station


The k8az team
The K8AZ team

  • K8AZ – Tom, great host with golden retriever Shane

  • K8NZ – Ron, contesting with K8AZ since 1960’s


The k8az team continued

  • ND8L – Ray, VP9/ND8L and VP9I for 2011 CQWW RTTY Contest

  • W8CAR – Dan, loves the low bands

  • W8WTS – Jim, has operated PJ2T

  • WT8C – Reno, also the official chef for the team

  • W5WZ – Scott, lowers the avg age of team

Receive antenna
Receive antenna

  • 15' high dipole for 160m

  • 15' high dipole for 80m

  • Hi-Z 8-circle array for 80m & 160m



The k8az station complexity
The K8AZ station complexity

  • Most antennas are available at all four positions

  • Everything is very well engineered

  • Inter-station interference was minimal

    • Dunestar 200 watt band pass filters between transceivers and amps

    • W3HQN high-power filters after the amps

  • Liberal use of copper grounding strap

  • All cables are neat & labeled

  • All controls are neat & clearly labeled


Switches for front or rear desk

  • Rigs loaded with INRAD filters


The m s strategy and remember the 10 minute rule
The M/S strategy – And remember the 10-minute rule!

  • Priority #1 - keep the run station running

    • Last 10 Rate < 120, change bands

  • The Hunt – chasing multipliers

    • 3 transceivers constantly tuning, listening, and scanning the DX cluster spots for new mults

    • ‘Stack' the band maps with mults to keep mult station rate high for the 10 minutes

    • As mults became harder to find, often the 10-minute clock was open and we would change mult band for a single mult

    • Sometimes the run rate slowed; have another receiver stack a band map, switch to that band to 'point & shoot' for 10 minutes, then switch right back to the previous run band

  • Across all contests

    • Highest QSO count

    • Highest CQ zone count

    • Highest DXCC total

    • Highest total score

  • An apparent #2 USA finish

    • Based on early 3830 reports


Observations
Observations

  • When the propagation is there, the Europeans are very loud! But, I think our openings in the south last longer.

  • Over the pole flutter occurs on more paths since the location is further north and the polar region appears wider.

  • The K8AZ call is recognized around the world.
