I forgot to post this update on the website. Me and SM2XJP installed the safety stop on the military tower. It’s not the best solution but it should work just fine. If for some reason the tower starts to rotate when it shouldn’t it will unplug itself. I saw this solution first on a multi-million dollar installation of a parabolic dish used for research and thought it was a neat solution.

Building some electronics
Been very busy at work this week but I have managed to get some work done in the evenings. This is some stuff to get the 60m tower and military tower rotational with the openASC-system and also built a notch filter to remove the 20m harmonics from 10m. It will be placed after the amplifier with the amplifier filter switch I built last year. So now I have harmonic filters for 80,40 and 20m. I need to build for 160m too and also add a notch on 15 for the 40m filter, which currently only attenuates 15m with about 6dB but notches 20m very well.
More work at the station
A weekend at the station
This weekend I spent a few days down at the station as my vacation begun. Me and SM2XJP went on Friday down to SM2UVU and picked up the plate that he got cut for us with the laser at his friends work. Its a 10mm thick plate with a total of 39 holes cut out with perfect precision. We also got some coffee and talked a lot about his project of putting up a 48m tower he built himself which is rotatable and will be filled with Optibeam antennas.
Later on Saturday my girlfriend came down and went into town and bought a door for the house. She also cut the lawn and I removed the roof that was above the stairs and cut away the rails so that I can finish up that side of the extra insulation of the house.
I did some work with the chainsaw as well and installed the metal oxide protection for the rotor cables down in the basement.
