Kaja-3 (10T1)

The multi-line telephone device Kaja-3 ('kaja' means 'echo' in English) was manufactured in 1977 by the experimental factory "Vihur" in Tallinn, Estonia. It has 10 line-selector buttons, a handset and a rotary dial on the front panel. The phone handset and electronics are from Latvian VEF TA-68M phone, integrated into the device, the main electronic board is "handcrafted" in Vihur factory Tallinn. The device has additional built-in speaker and microphone, allowing it to be used also in hands-free mode. It was possible to connect up to 10 lines simultaneously to one call. The front panel is covered with black imitation leather (dermatine) and features attractive stylised enamel badges of Vihur and Kaja-3 brand names.

This rare example of Soviet-era Estonian industrial design was saved in 2026 from the Põdrangu collective farm (Põdrangu sovkhoz) in Estonia. In fact, the same collective farm had a complete set of different Kaja devices, including a dispatch console, all manufactured at the Vihur factory in the 1970s.
