PA1T

The SteppIR antenna in tower 4 had a broken element. I will repair it and make it stronger. For this it has to come off the tower. When repaired it will go to tower 7 as part of a stack with the 4 el StepIR that is already on that tower.
Last year I bought a 16 elements GXP for 10, 15 and 20M. This antenna will be mounted on top of tower 4.  Also I have build a 9 element 50MHz antenna witch will also be mounted in tower 4.

On Saturday 12 October I was getting help from Peter PA4O, Nap PA1NG and Thomas PA1M and crane driver Henk van Wieringen.

On the pictures below you can see the work what is done. In 3 hours the job was done. To fasten the coax and make some changes I had to go up again a couple of times.

To switch all the available antennas for the two HF stations Thomas PA1M and I have designed and build a new antenna switch system. All the switches are steered by MicroHAM software and hardware.
All the switches are home made by several designs. Last part off the new system is to build 6 high power bandpass filters and buy 3 triplexers. When the filters are intalled I will make the antenna cables to their exact length

In this part the four radio have their coax entry.

In this part are the switch for each band.

Here are the U links from MicroHAM witch wil switch call the realys in the switch as also the other parts outside like stack switches relays for tuners etc.

Since last update of the shack I made some changes.

I added a few rotor control boxes (RT21 Green Heron) to steer the rotators in the top of the rotary towers.
I added two Meastro’s for the Flex 6600 radios’s.
I build a rack for the second HF station the same as is in use for HF and VHF station.
The last updates will finalize this part of the station.
More updates in the near future will take place outside.
