YL1VA is club station of Ventspils University College (Ventspils Augstskola in Latvian)

One of main goals of our club station is to provide students with oppurtunity comunicate with real orbiting satellites and encourage�student interest of radio/satellite telecommunications and technologies. We have all necessary equipment to communicate with LEO satellites and operate as satellite base station, which will also be needed in near future for servicing Latvian first satellite.

Of course, since we got our operating license, students can learn how to use radio station equipment, to practice their HAM radio operator skills on both HF and VHF/UHF bands, make first QSOs, take part in contests and to go in this great hobby.

Our main equipment:

  • RIG: ICOM 9100 tranceiver with MicroHAM Keyer II interface
  • 2m ANT: WX220 2x10 el. crossed Yagi. G = 12.3dBd, HPBW(H/V) = 38/35deg
  • 70cm ANT: WX7036 2x18 el. crossed Yagi. G = 14dBd, HPBW(H/V) = 30/28deg
  • HF ant: 80m wire, Titan DX. 80m wire upgradeable with matching stubs for other bands as well (We are working on it... ;)).
  • SPID Az/El antenna rotator with computer controled controller
  • Kantronics KPC9612+ TNC for 1200/9600 FSK packet
  • SDR receivers: USRPs, Funcube Dongle p+, RTLSDR
