… the Core Team at SK3W were making the last heavy lift for the antenna season.

The rotor parts and 40m Yagi was lifted to top of the tower this weekend. Antennas was dissembled at the 34 meter level of the tower and then lifted piece by piece to the top. Then re-assembled and tilted to its final position on the mast. Three different ways on how to get the antenna to the top of the tower was considered.

• Use a tram-wire: No good wire available.
• Loosen the guy wires and use temporary guys: Never tested, risky?
• Lift the antenna in parts: Slow work, but MUCH faster if we have can have persons in the tower.

This was the third time I lifted a 40m Yagi in this way, and it was much easier with the help from Jonas SM5PHU. We had some wind in the end, but the antenna is very well balanced and went in position without arguing.

The ground crew was excellent this weekend, staffed by SM0MXO Hasse, SM0GNS Peder, SM5AJV Ingo, SM5EPO Peo and SM3XIK Anders. Special thanks to Jonas SM5PHU who for the first time could look down on the old the 60 m Jaaaaska tower.

Since last post the new guy wire level is in place at 48 meters, and also some more sections.

Work has been slow, mainly because of missing ground crew, but also due to limitations in the winch and wire. On Saturday we will try to continue work, if we find more ground crew. There are a few section left until next guy level, and the top sections with antennas can be mounted later in September.

Today I got some help from Tony SA3BGM. We moved all cables for the 60m tower to a new housing, where all control cables were terminated and feeders from the house will be connected to cables coming down from the tower.

Yesterday I cleaned the chain for the 60m tower rotator. The bottom bearing need some new grease, but it is difficult to apply. Later this week we will use high pressure air to clean the bearing, and the cut or drill a hole were it is possible to add new grease.
