Added power winch on tower

Finally got to replacing the POS manual winch for the Optibeam OB12-4 tower with a 110 V 2000 lbs hoist. What a relief. The tower went up to 75 feet in about 60 seconds. No effort at all. So why is the hoist offset on the platform? Because the cable needs to be in close to the center of the tower.

April 18 – World Amateur Radio Day

Today is World Amateur Radio Day. 

World Amateur Radio Day is approaching! — BridgeCom Systems

Every April 18, radio amateurs worldwide take to the airwaves in celebration of World Amateur Radio Day. It was on this day in 1925 that the International Amateur Radio Union was formed in Paris.

Amateur Radio experimenters were the first to discover that the short wave spectrum — far from being a wasteland — could support worldwide propagation. In the rush to use these shorter wavelengths, Amateur Radio was “in grave danger of being pushed aside,” the IARU’s history has noted. Amateur Radio pioneers met in Paris in 1925 and created the IARU to support Amateur Radio worldwide.

Just two years later, at the International Radiotelegraph Conference, Amateur Radio gained the allocations still recognized today — 160, 80, 40, 20, and 10 meters.  Since its founding, the IARU has worked tirelessly to defend and expand the frequency allocations for Amateur Radio. Thanks to the support of enlightened administrations in every part of the globe, radio amateurs are now able to experiment and communicate in frequency bands strategically located throughout the radio spectrum.  From the 25 countries that formed the IARU in 1925, the IARU has grown to include 160 member-societies in three regions. IARU Region 1 includes Europe, Africa, the Middle East, and Northern Asia. Region 2 covers the Americas, and Region 3 is comprised of Australia, New Zealand, the Pacific island nations, and most of Asia. The International Telecommunication Union (ITU) has recognized the IARU as representing the interests of Amateur Radio.

 

2023 Bouvet Island – 3y0j DXpedition

2023 Bouvet Island  – 3Y0J Dxpedition. What a feat to even be able to land on this forsaken island to activate Bouvet Island in the Antarctic for us radio amateurs to be able to work the station they were able to set up.

Bouvet Island is an island and dependency of Norway, and declared an uninhabited protected nature reserve. It is a subantarctic volcanic island, situated in the South Atlantic Ocean at the southern end of the Mid-Atlantic Ridge, making it the world’s most remote island.

The tower finally came in, and I didn’t waste any time before starting to dig.

The 6″ hole was dug using a 1 ft bit with two extensions. It got heavy after a while, so used the tractor to lift it up after the bit filled up.

Nice and smooth all the way down.

Again, used the tractor to lift the massive MP2 pole into the hole, and proceeded to level it up.

Nice and level.

A couple of weeks later, and the pole is set completely back-filled and hard-packed all the way up to the surface.Tower carefully strapped underneath the bucket using plenty of wood for support. Yaesu 1000 DXA rotator and mast already installed.

 

 

Beautiful…

Cabinet in place, containing coax poly-phasers, roter control arrestor, and other equipment.

Fully extended to 70 ft.

This was an easy two person job, with the help from my lovely wife. She was doing the supervising. This install was a long time coming. Now for the next stop, getting the Optibeam OB 12-4 yagi installed on top, using a crane. More to come.

9/16/2022: Finally got the crane in to lift the Optibeam up in the air, and bolted onto the nested tower. What a beautiful sight.

Yours truly bolting the antenna to the mast plate.

Now on to digging a trench for pvc, and pull cables.

Business end

Trenched in a few minutes, about a foot deep. 

Started working in the tower cabinet. Connected up the Poly Phasers and the rotor control lightning arrester. Plenty of space in there to add a 4-position coax switch a little later. I added a 120 V feed into the cabinet to enable the use of a 120 V electric winch. Cranking this thing up using a manual worm gear winch that was supplied by Aluma, gets old pretty fast.

Almost done. Need a RatPak antenna switch in there.

All Done….
