W5WZ visits K8AZ

2011 CQ WW SSB

M/S High Power

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!

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
Switches for front or rear desk
  • K8AZ personally switches these – no one else!
front desk positions a b
Front desk, positions A & B
  • Rigs loaded with INRAD filters
rear desk positions c d
Rear desk, positions C & D
  • 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

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.
