Comments:

With high anticipation, regular ops W5WZ and WM5H had prepared the W5WZ station
for a serious Multi-Single effort for this contest, with full ability for
in-band S&P at full power using EA4TX interlock. A portable tower set up
700 feet west of the main tower, with KT-34XA at 60 feet, an 80-meter dipole at
55 feet, and 40-meter dipole at 45 feet provided sufficient antenna separation.
First-time guest Dave K5UZ joined the team for the effort.

As always the food was excellent, the station performed well – except the air
conditioning – in the 100 degree heat and Louisiana humiditiy it couldn’t keep
up with the ops and 3 amplifiers.

Thanks to all for the QSOs!
–Scott, W5WZ

Comments:

Weather was so nice, spent as much time outside as possible.  Made good progress
on preparations for my new 80 meter 4-square, soon to be installed.

With the stay-at-home order in place, I felt guilty spending time away from my
family in the evenings, so went inside with them.

Comments:

Several “firsts” for the W5WZ station and team for this contest.

First time for Ed, K5OF to join the W5WZ team, flying in from North Carolina.
It was good to have him on the team.

K5OF at Run1, and W5WZ at Run2

First time for Dallas, K1DW to guest op at W5WZ; he operated from his home in
Texas, by remote controlling one of the K3’s at W5WZ.

First DX contest since expanding the beverage receive antenna farm.

First contest since moving the 80-meter dipole from 77 to 105 feet.
First contest with the EA4TX interlock installed, allowing easy Run/S&P on a
single band.

Marsh KA5M also drove in from Shreveport (100 miles) on Sunday.

Special thanks to Sharon KW5MOM for the pot of gumbo and the pot of chili; Bobby
for the usual spread of deli meats and breads; Ed for pre-contest dinner on
Thursday night.

WM5H at Run1

As usual, too much food AND lots of fun!

Since last weekend\’s NAQP CW, all the shack Window 7 computers were replaced with Window 10 computers. Added a single Logitech wireless keyboard/mouse – discovered that RF causes problems with – putting both computers in a F1 voice keyer loop. During the 15 meter run in the 2nd hour of the contest, something in the RF path failed, sending the SWR very high, prematurely ending our work on 15 meters. No other problems. Me and Bobby both stayed in the seat.

Our best performance to date in an NAQP!

Thanks for the QSOs, and thanks for those that accepted our invite to move to other bands.

2019-CQ WW SSB @ K8AZ

I made my 7th trip to Chesterland, Ohio to the fantastic station of Tom, K8AZ for the 2019-CQ WW SSB contest. Yes, it is a long drive – 16 hours or so. But the camaraderie with the gang makes it all the better!

As usual, I spend some time on Friday helping Tom with various maintenance, repairs, or installations of new items. This trip was no exception. Many hands do indeed make light work!

Tom takes a pre-contest walk around the antenna farm. This time, we found the rope supporting the SW element of the 80-meter transmit 4-square had broken, and the result was a rope tangled up in the elements of several yagis on a rotating tower.

In waning day light, we worked to free the rope from the tower such that the 80-m antenna would be usable. The rotating tower is 15 and 20 meters, so we parked it toward Africa for the night. Once the rope was free, we managed to get it positioned such that the 80-m antenna functioned for the overnight operating period.

The next morning, it was raining. The forecast called for increasing winds throughout the day and into the night. K8AZ and I ventured with bow and arrow to get a string over the appropriate tree. First challenge was using a sling blade to clear walking paths and work areas in the raspberry thicket, then cross a creek to find the loose end of the rope. Second challenge was to place the string. First shot success! Then pulled a larger string, and at last the final rope. With the antenna repaired, back to the house for shower and then operating time again.

Near sunset on Sunday night, suddenly 80-meter 4-square SWR went really high. Upon inspection, we found the NE element had broken loose from the feed point. Hauled a ladder out and worked beyond sunset to complete the repair with 20 minutes left in the contest.

Highlights of this contest: seeing my friends K8AZ, K8NZ, W8CAR, WT8C, AA8OY, K8RR, W8WWV, K8BL; riding in and driving a dual motor Tesla Model 3; meeting KE3X and talking contest strategy; and working CN3A on 160m with my own call!

Station Maintenance Oct 11 & 12, 2019

Over time, things up in the air change! I’d put together an ambitious to-do list!

Towable 55-foot reach aerial lift. Electric, runs on self-contained batteries. Cost $375 for the weekend.

Bobby WM5H and I rented a 55-foot aerial lift, because the 40-meter feed point is 12 feet away from the tower. With Bobby as ground crew and Scott in the bucket, we were able to complete:

  • Repair 40-meter Yagi at 52-feet above ground. Problem was a fried balun connector.
  • Repair 15-meter Yagi at 52-feet above ground. Problem was loose hardware connecting hairpin to driven element.
  • Use lift to rework 17-meter tower
    -Add back stay.
    -Secure new hard line and control cable to tower, leaving loop for tilt-over.
    -Replace rotator loop feed line.
  • Use lift to cut down storm-damaged ash tree in sections. This was more of a chore than expected.
  • Trim a large pine tree behind shop, strategically leaving limbs for easy wire antenna support. Installed a pulley at 55 feet above ground on a limb.
  • Install new 580-foot beverage wire for SW direction
  • Install new 580-foot beverage wire for SE direction
W5WZ accessing 40-meter feed point. The 15-meter feed point is first element on the left side of the tower along the same boom
Fried female UHF connector for the input of the 40-meter 1:1 balun at the feedpoint. The balun was a CAL-AV LABS high power bead balun.
Post-repair sweep of the antenna from the main run radio. This is how it is supposed to be!

At the end of the second day, some items remain to be completed:

  • Move 80-meter Inverted-Vee from 77-feet to 105-feet. Extend feed line as required. Tie out ends as required. Modeling by KA5M shows 1-dB gain increase at 20 degrees elevation; should be a worthwhile change.
  • Build new 160-meter ground plane vertical with elevated radials in new location. Tie top support rope off near top of tower. Run hard line as feed line to new feed point.
  • Re-arrange several wire antennas supported by trees. Replace string with new antenna rope.
  • For the two new beverage antennas, run feed line on the ground. Drive 2 ground rods, install transformer and feed point termination.

W5WZ traveling to K8AZ for the 2017 ARRL DX SSB

What is it that can cause a man to desire to drive solo for 16 hours and 1,100 miles, then sit in a chair for 48 hours, and then drive solo for the 16 hour 1,100 mile return trip ?  ARRL DX SSB contest, of course!

Once again W5WZ will be a guest operator at K8AZ near Cleveland, Ohio.  This will be my fourth time to join the group for a contest at Tom’s excellent station.

Stay tuned for a summary of the weekend!
