UT7CL made me this nice picture. The crazy guy on the photo is me during the CQWW CW contest, in bad need of a shower.

Not much happening right now because I’ve been sick for over a week. So I went out and took a few pictures of the snow covered antennas. The project for the near future is finishing the support-operating position electronics, so I can have it ready for the CQ 160m contest coming up in a few weeks.

Comments Off on Some various stuff
Yesterday I decided to remove the rotor of the big 60m tower. This is because it is currently not strong enough, it has got some cracked weld and also I found a big crack in the metal when I removed the gearbox. This is however rather easily fixed and I will add some more iron to it so that it gets more stiff and doesn’t flex so much.
When SM2XJP arrived I decided to climb the tower (I don’t climb it when I am here alone) to add the boom side support for the 20m yagi and tighten some stuff up on the 40m yagi. I also needed to attach the cables properly to the tower. I use duct tape every 50-100cm or so on cables running in the tower, to avoid them from bashing against it when its windy. When I arrived up to the top 20m yagi the boom support was missing its clamps, so I could not do that. However I finished up the coaxes and on the way down with help of SM2XJP on the ground we lowered the 20m temporary 3el yagi @20m and also the low 15m yagi which will be moved up to 17m when the top 15m yagi (27m) and low 20m yagi (23m) is in place.
I also have fixed the cables between the 7/8″ in the tower and the 7/8″ on the ground. I used 3 pcs of RG-217 for this with 7/16″ connectors. I also put the RG-17 for the 160m vert, 80m 4-SQ and 40m 4-SQ in the ground and routed them into the switching room together with the other coaxes.
Today it was rainy so I decided to build the verticals for the 40m 4-SQ. The tips were made out of an old ZX 15m monobander and I added some 31 and 35mm tubing to that plus put 12mm tips (tip of the ZX yagi was 15mm). This turned out great and hopefully I will be able to have them un-guyed since they stand rather well protected with forest all around.

The current big project at the station is to get the 3el fullsize 40m yagi up at around 60m in the big tower. This will be done during the week with help from SM3SGP. Since its hard to hoist one of these and clear the guy lines we will build the beam up in the tower. So first we hoist the boom, then the reflector/director and last the driven element. SM3SGP has done this before at his QTH (SK3W) with success.
I made a brief trip to the work QTH where I during a few hours made 6 pcs of boom to mast plates, 4 pcs of driven element plates and a lot of isolators for the two 15m yagis and the last 20m yagi. So now I have pretty much all pieces to get all antennas in the 60m tower completed except the 2nd 40m yagi, which will probably be done next summer because of some material shortage.
