Estonian student satellite workgroup has two radio stations at Tartu University Physics Institute:

"HAM station", which consists of:

  • Kenwood TS-2000X transceiver
  • 80m delta loop antenna
  • Tribander JP-2000 for 20, 15 and 10 meters (works well also on WARC bands)
  • A 2-meter band antenna with 17 elements made by M2 Inc is deployed above the tribander
  • Asimuthal part of Yaesu rotator G5500

Satellite groundstation consists of:

  • Icom 910h transceiver with 23cm module
  • Two 2m Wimo crossyagis, four 70cm Wimo crossyagis and preamp for 70cm band, one 15 element "homemade" DL6WU yagi for 23 cm band.
  • Rotator Yaesu G5500 which allows to track satellites 450 degrees in azimuth and 180 degreesin elevation
  • Small number of accessories and controllers made by students
  • Station is controlled by computer, running Ubuntu Linux with latest GPredict and Hamlib software. Because of used software, remote control of the station is not really a problem.

HAM-station is used mostly to give students possibility to train their skills in radio communication during radiocommunication courses. Some more active young amateurs are using stations also for contesting, using both ES5EC and their own callsigns.

The satellite groundstation has been used to communicate with many other student satellites. Sometimes satellite station has been used to talk with other hams over satellites as e.g. AO-51, AO-27, VO-52 and FO-29.
