2003New middle class PLL synthesized transmitter TRAINER PLL
2004Automatic monitoring receiver MONITOR 2004 and CONTEST 2002 transmitters successfully used at World ARDF Championship
2005All equipment reconstructed to SMD technology and modern component base. New products: HF receiver SUPERFOX3,5GX, SportIdent radio data link system
2006New transmitters MICROFOX HF and MICROFOX VHF replace all older MICROFOX transmitters
2007New transmitters TRAINER2007 and CONTEST2007 replace all older TRAINER and CONTEST transmitters. CONTEST2007 has a built-in automatic antenna tuner
2009New VHF receiver SUPERFOX145E. In addition, the company enters the area of animal tracking equipment (automated animal tracking system BAARA and advanced programmable radio tags BIOTX).
