PJ2T Outside Maintenance Plan
Updated 22 December 2017


Non-Routine Maintenance

Project Target Completion Date Labor Needed Parts Needed Notes Cost Estimate
Replace Europe Tower Undetermined Three ground, two professional climbers, crane operator Various, see list in project document See project document ~18,000
Rebuild SA tribander Prior to Europe tower replacement One climber, one ground Parts on hand obtained by N7IR Take down antenna, clean and re-seal traps, replace any questionable parts Parts on hand; only cost will be travel subsidies for people
Replace WARC rotor March 2018 One climber, one ground helpful New custom made backer plate which should be at Signal Point, made by W0CG in 2016; specialized stainless rotor bolts and flat washers should also be on hand Grinder will be used to remove old rotor with fused bolts, replace rotor, send old one to CATS for rebuild; wiring will have to be spliced by hand on tower due to non-standard connector Rebuild rotor ~$300 including shipping
Inspect black rope on both elements of US/JA 80 meter wire beam and replace or reposition if needed March 2018
Completed 23 February 2018
One climber, one ground None Rope may be weakening at the pulleys; if needed, cut off some rope and attach elements to fresh ends 0
Tune US/JA 80 meter beam per K6AM procedure Fall 2018
Completed 27 Feb 2018
One climber, one ground Signal strength meter for far field Requires lowering down one element at a time, tuning, and then restoring elements to normal position 0
Install new driven element spacer on Ridge tribander Late 2018 One strong climber, three ground New Bencher spacer Spacer on east elements has broken and fallen off; reinstall with UV protection tape ~ 150
Install Pacific tribander on new Europe tower so it truly points west Concurrent with Europe tower replacement Two climbers, two ground Additional N8LGP side mount cradle with offset bracket; needs to be designed and fabricated Contact N8LGP and also study available known designs; get the boom off the tower leg ~ 400
Retune Europe 3 element 80 wire beam 2019 ? One climber, two ground None Collapse two elements at a time, attach MFJ to feedpoint, tune front 20 KHz below and back 30 KHz above; model this first 0
Replace missing reflector element tip on Europe yard 20 Concurrent with Europe tower replacement One ground Element tip is in shack in front of kitchen backsplash Install new element clamp if needed 0
Inspect and repair as necessary 40 yagi Concurrent with Europe tower replacement Two ground Kit of parts yet to be determined We will only have a short time, a couple hours, to re-hab this beam where needed. This will be planned in a separate document. ~ 450
Retune 6 meter yagi DE to 50.100 March 2018 Two climbers MFJ This can be done without taking the antenna down 0
Prototype a US ocean vertical for 80 2019 ? Three ground Fabricated vertical, base, and all support parts; ~500 ft coax Research K2KW material on optimum spacing from salt water, then design a temp vertical to be placed by the water about 300 feet from station; install it temporarily and then do on-air comparisons ~ 500
Investigate purchase of land on Ridge 2018 ? Attorney None Engage a Curacao attorney to determine with the Kedaster office the present owneship of that land and the possibility of buying a section; research right-of-way laws on the feedline route. ~ 1500 legal fees
Add two feet vertically of concrete to base of WARC tower 2019 ? Two ground Concrete forms, cement, sand, gravel, rebar We added three feet to base in 2001 because it was hopelessly corroded. Now the same thing is happening to the foldover assembly. Safe fix is to encase it in concrete. ~ 200

 


Routine Maintenance

Outside maintenance encompasses ongoing care of all of the station components that are outside of the house, including towers, antennas, feedlines, rotors, radials, cabling, switchboxes, and transformers. Ongoing care includes rust and corrosion control, periodic inspections, and replacement of broken components. (Upgrades, such as addition of antennas, are NOT considered maintenance.)

Note 1: Only emergency triage scraping and painting will be done on the Europe tower prior to its replacement for safety reasons.

Routine Tower Non-Painting Maintenance

November 2017: Dug two inches down in ground at all guy anchor points; no corrosion noted.
March 2017: Cut tree branches away from Europe Stone guy set.
Ongoing: Inspect all guys, equalizer plates, exposed metal for corrosion and control it.
Periodic: Remove tape from deadends on tower and inspect for corrosion; re-seal.
Periodic: Cut stick tree away from overhead cable bundle.
Ongoing: Keep Beverages clear of vegetation and test termination resistors.
Ongoing: Spray paint Heliax on Ridge with camouflage paint.

Cost Calculations

One Time 2006 Cost

We need assistance from Herko and his helper to get the big antennas down and back up with minimal disruption to contesting. Four full Saturdays will be needed.
