Added two new beverage receive antenna – southeast and southwest.
Southeast is 580 feet long.
Southwest is 480 feet long.
Installed them both 2 feet above the existing beverages for NE and NW using PVC pipe as a vertical standoff.
Built a home-brew EZ-Way Wonder Post to ground-mount the EZ-Way Tower that had been on my utility trailer as a portable tower. This 50 foot tower will be used for 6 meters, 2 meters and 70 centimeters. I rebuilt a Ham-II rotator for this project.
6-meter antenna is a Hygain VB-66DX – 6 elements on a 24-foot boom.
Don’t yet know what will go up for 2m and 70cm.
Implemented an EA4TX INTERLOCK to keep us honest in M/S and M/2 contesting.
And a good time was had by all. 12 hours B.I.C. We had trouble with the SixPack with 15, 20, and 40 meters. Had to coax jump around the SixPack to use 15 and 40 on the right radio. No time to fix during the contest!
Thanks to all for the QSOs, and especially all the >3 band QSOs.
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.
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.
Over time, things up in the air change! I’d put together an ambitious to-do list!
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
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.
