WARC beam finished

Posted by sm2wmv on May 3, 2016 Comments Off

Last week I spent most of the time finishing up the WARC yagi. I made the side supports for the boom, attached the coaxes, made the RF-chokes and also mounted the winch so it can be hoisted. Hopefully weather allows us to put it up during this coming weekend. Left to do is to climb up with the lift rope and get the tram wire mounted. Then we will need to tune the beam and I will first try to get the 17m at the right frequency before I try to mess with 12m.

I will also need to build a switch that toggles between 12 and 17m since I only have one coax up the tower and I don’t really feel like wasting another one for WARC. I will use a switch to use the 15m 1 1/4″ coax going from the tower to the switch room for WARC as well. The plan is that when there is a coax going there for 80m that one will be used instead for WARC + 80m.

Now when thinking about it I should really have another coax running up to the WARC yagi since I would just need one switch and not two, plus I would not need to have it up the tower.

Keep tuned…

Antenna and house work

This weekend me and Hicco went down to SJ2W. We got quite a lot done even though the weather was shifting between sun, hail and snow. Later during the week (thankfully I was not there) it came down 15cm of snow (!). I am tired of the winter now and I want summer!

I bought and mounted a roof rack on the car so I was able to go into the village and get some wood for finishing up some details on the house. I also cut the wall panels on the front of the house so its straight and nice. I attached the planks to the house even though its not painted, so it will be needed to take loose (just four screws) to be painted when its warmer outside. The house also needs another coat of paint.

On Sunday I spent some time to assemble the 2el 40m yagi that I built most of the parts for last autumn. It is meant to be put up in the inband towers at 30m and is an own design.

This weekend I am going down again and we will see what projects the weather will allow me to do.

I also played with Hicco. Anna has been training with him a lot and I got quite impressed when I tried this…

Electronics

Not that much radio related has been done so far this year. I have spent a few weekends at the QTH but not done much major stuff, just some organizing in the basement etc. Now however sun has appeared again and my motivation is getting better and better. Plans for this spring is to finish up the house and the inband tower. I will also try to get the WARC beam up. There is a lot of minor stuff I also need to spend this summer doing, such as small houses for all rotors to the towers etc. There is also plenty of work to be done getting inband to work with remote access link for antenna switching etc which will be run over XBee. I have been looking at making some HPF for them to make sure I don’t get any interference from the HF bands, I dont know how much I should trust the RF-frontend on those modules.

This weekend me and Hicco will go down and hopefully weather is good enough so I can do some outdoor work.

Stay tuned…

Last weekend

Posted by sm2wmv on March 8, 2016 Comments Off

Here is a little update of last weekend. I went down to SJ2W on Friday and met up with SM2XLL in Skellefteå where we ate dinner and continued the trip to SJ2W. SM2XJP helped me to unload the car which was full of stuff for the QBL including the amplifier, transformer etc itself. I also got with me some archive cabinets down which I really like to store tools etc in.
