Changes EME rotator

Mar 092011
 

Today I modified the read out from the Prosistel rotator witch moves the eme system from potentiometer read out to pulse read out. The older Prosistel rotators who are in the other towers have the motor straight up and had a fan witch I removed and on the shaft I made a magnet. At the cover I had connected a pulse reader.
On the newer Prosistels this is not possible anymore because they don’t have a fan. I now mounted a motor unit of an old actuator parallel to the motor of the Prosistel. I now can use the pulse read out of this actuator to read the pulses. I had to reprogram the Green Heron rotor box from potentiometer read out to pulse.
This is easily done by changing two jumpers in the box.

VHF UHF SHF contestweekend.

Mar 062011
 

Saturday morning Thomas PA1M and Jan PA0VAJ came to help the operators Peter PA4PS, Johan PE9DX and myself to set op an extra tower. After some coffee and pie we started to set up this small tower with the 4* 9 elements Tonna antennas witch compleets our 4 tower station for the 144mhz part of the contest. Then we fired up the computers, radio and amps and made it all to a working station.
Johan PE9DX arrived also. The contest started at 1500 local and the condx where good. Sunday the contacts slowed down but the condx where still ok and some nice dx was worked.
Everything played well and thee where no major problems.

Mounbounce C56EME

Feb 172011
 

With Johan PE9DX, Eltje PA3CEE and Rene PE1L in Gambia as C56EME I had to startup the moonbounce part off the staion to make a qso with them. Due to temporary less time playing moonbounce was a while ago. What is was expected was true. The actuator for elevation was not willing to move. With a smal ladder  I was able to give the actuator a  push on its head and things where running again. After listening a while I worked BD4SY for a new DXCC and after that I worked the boys in Gambia also for a new DXCC. I made some other contacts and I can say that the station still works fine.

The PACC contest

The conditions where bad but it was fun to play around. Everything stayed alive and the station worked fine.
SO2R is a challenge. Hopefully I can start this spring with building two new four squares.  Then I have more antennas to choose from which is making SO2R more fun.
