In October 2008 many EME-ers were pleasantly surprised by Bruce PY2BS becoming active on 23 cm.
Up till then Brazil had been a land that could only be caught with great difficulty. On the whole, South
America is a continent with remarkably little activity by way of the moon, certainly at higher frequencies. Bruce really took to it, kept enlarging his disk and got active at more and more frequencies.
Meanwhile his disk has ‘grown’ from 2 m to 4,6 m and now he is active at 70 cm, 23 cm and 13 cm; 9 cm and 6 cm are being worked on. Bruce got quite interested in the Dwingeloo telescope and during the weekends we were active with PI9CAM, we have been able to enter Bruce in our log a couple of times.
Last year he turned out to be planning a few weeks’ visit to Berlin with his wife and child. During our
regular mail-contact the idea grew of visiting the DT during this Berlin period. |

 With our EME team we decided to use the ARRL November edition of the EME contest to activate PI9CAM for 13cm, 9cm and 6cm.
The required equipment was arranged by PA0HRK, PA0JCA, PA3CEG , while the antennas and the 6cm SSPA was lend to us by ON7UN en ON4BCB.
The antennas were mounted off-set to the existing antennas of 23cm and 70cm. This requires a modification of the tracking software, kindly implemented by PE1RXQ.
Operators: PA3FXB (.AVI), PA2V, PA3HHE, PC4M, ON7UN, ON4BCB, PA0PLY
The first moonpass mostly 13cm was activated, with a lot of SSB contacts. Echo’s were marvelous with S9+ signals from time to time.
Nice contacts were with Gerard PA0BAT in SSB with 54/53 signals. Jacq PA3DZL, claimed we generated the strongest signals while we qso’d him in SSB with 54 signales.
PY2BS (.WAV) was worked with 576 in SSB. After connecting another TS-2000 we were able to listen for US stations on 2304Mhz; Qso’s with: WA6PY, K8EB, WA8RJF.
We remarked the very narrow beamwitdh, due to the size of the dish, and it required constant optimizing. Also during the second moonpass on 6 and 9cm this effect were very noticeable.
Op 9cm mainly euopean station were contacted such as: PA0BAT, G3LTF, OK1KIR, but also VE6TA en W5LUA
Petros SV3AAF (.WAV) was contacted foor the first ever PA-SV on 6cm with 559 signals.
Additional to this success: ES5PC, PA0EHG, F2TU (.WAV) and OE9ERC.
Results.
The final results of this nice weekend:
At 13 cm 43 QSO's of which 17 in SSB
At 9 cm 8 QSO's
AT 6 cm 6 QSO’s SV3AAF (.WAV) First! PA-SV |

The Dwingeloo radio telescope has not been used for astronomical research for some time now. ASTRON, Dutch institute for radio astronomy, part of NWO and also the present owner of the telescope, has chosen to make the telescope available to interested user groups.
To manage the radio telescope, the CAMRAS foundation was founded on January 29, 2007. CAMRAS stands for "CA Muller Radio Astronomy Station", in honor of ham Prof. Muller. |

Robert Langenhuyzen has been digging into times of yore. This picture was taken at the farm where, in the beginning of times, outdoor experiments were done. Here you’ll find a rather big corner-antenna. The man in the white coat in the picture was ir. Houtgast. He can be recognized by his always featuring an Basque beret. |
