Today I got the message that the permit for the four new hf towers is approved.I already have ordered the towers. Building will start in March 2013.
The 27m high 160 meter vertical was not performimng as it has to be.
I disconected the relay box and made a few changes.
The wire from the coil to the vertical went trough an open hole in the box. I changed this and made a Pl comnector on the box. When I was running more as 200 watt the swr became sky high. I asked Jan PA0VAJ to see what happens while I was txing. We where ready very fast. The pl connector was smoking….
After that I removed the pl conecotor and conected the coil to the vertical with an inner part of an rg213 coax kable. I made it a bit water proof so it will last this winter contest season. Next year ever thing will change and the I wil build a better box.
I participated in the contest. Did a lot of search en punce.
I made 1051 qso’s.
Today I went up the tower to switch the six meter system from two coax lines to one coax line.
I thought I could do this job in about 15 minutes. At the end it took me more as two hours. I tried to loosen the coax which is going to the six meter yagi from the relay box but there was no movement at all I went down to the shack to get more tools. I tried hard but still no movement . Then I decided to remove the swivel form the connector and pull the coax out and mount a new connector. So I did. After that I already was cold and decided to finish the job and remove the preamp and the relay box today. The only two things still up there now are the revive line. I taped it well and I can use this one for the new 7oMHz yagi which I will put up there in spring next year as I remove the C31XR HF yagi which will go to a new tower. The 12v switching cable. is also there but taped it also and will remove it in spring.
After a discussion with well known 6 meter dxer Johan Minnema PF7M I decided to go back to one coax line to my six meter yagi. The last years since I have a preamp in the tower I always had two coax lines and a coaxial relay on the top of the tower. The switching was not as good as my to meters system. On two meter I switch in the correct order. On six meter my pa saw sometimes very short a bad swr. So I decided to change to simple. One line! No preamp anymore.
First I have to bring back the FTV-1000 transverter back to one output. This is now finished. I switched the coax relay at the tower to the tx position and tried it. It is working fine.
