old QTH from 1987-2001

Picture right shows the current shack setup which consists of a YAESU FT-1000MP as main and a Yaesu FT-847 (not on Foto)as spare rig. On the right you see the ETO 91ß amplifier.On top of the FT-1000 are 2 monitors for logging and packetclusternetwork. Usually I am connected to internet- and local packetcluster. The spots are selected at the computer on the right and are deliveredwithout dupes to the logcomputer on the left. This little network runs with 2 TNCs only and the idea was given by Klaus, DJ4AX.On the left site of the picture you can see the control boxes for the 40m 4-Square, the rotator control and the main box for switching all the antennas.The big box below the rotator control is responsible for switching the TX and RX antennas. All antenna relays are outside the house.



At the picture on the right you have a sideview of the station.In the back you see a coax patchfield which was installed in July 1999 after a big stroke of lightning. I lost half of my station due to high voltage on the coaxlines and the protection earth.With the patchfield I am now able to disconnect EVERY cable which is coming from the outside and is going to the station.This includes all coax lines, the rotator control cable and of course every powerline.



This is the new powerline controlunit which was also installed after the nightmare in July 99. Beside the coax patchfield I am now able to disconnect every 230V cable remotely from the shack by strong relays.



The picture on the right shows the left side of my shack with my"working horse" in the middle and some stuff like printer,scanner, phone, etc around. This computer is mainly used for internet, multimedia and some QRL work.



On the right you can see my main antenna system,which consists of a KLM KT34-XA for 10,15 and 20m.2.5m above is a rotary dipol for 40m parallel to the boom of the KLM. Another 2.5m higher is an A3WS for the WARC bands.This is a 3 ele beam for 12 and 17m andworking like a rotary dipol for 30m.
The tower has a total height of 24m.



The 6 Ele KLM Yagi has a boomlength of 10m and 6 active Elements on 28 Mc. On 15 and 20m 5 Elements are in use. The 40m rotary dipol is not fullsized andreduzed to 13m of length by coils. The A3WS on top is a very lightweight antenna with a total of around 10 kg. Although there is a lot of aluminium on the tower, you can`t notice any kind of coupling.Everything works fortunately very well.



Another shot from the tower base. On the left you can seeone of the verticals of the 40m 4-Square, which is used asan alternative antenna to the rotary dipol on the mast.The complete tower is gammamatched for 80 and 160m operation.A total height of about 24m with some aluminium as toploading should be used as a vertical.....



At this picture you can notice the gamma wire to match the tower on 80 and 160m.



Here you can see the base of the tower. The box on theleft houses all the relays for antenna switching and the dummy load that is connected to the 4-square hybridcoupler which is installed some meter away. The case on the right protects the 80 and 160m capacitors against weather. All coax and control cables are layed underground to the shack which is some 40m away from the tower.



Picture right shows the box for the 80/160m gammamatch.



On the right you can see the 80 and 160m gammamatch.The capacities consists of commercial JENNINGS Vacuum C`s,0-1000 pF at 15 kV. I use 3 fixed tuned C`s switchable with high voltage ceramic relays for 160m, 80m SSB and 80m CW. This antenna was completely rebuilt after the stroke of lightning in July 99.
