Manufactured by Tento, Minsk Radio Works, USSR.
The different models of the multi-band receivers „Selena“ were probably developed at VEF in Lithuania and then produced by Minsk Radio Works, the manufacturer's name on the back is TENTO.
The sets exist in different versions, with different shortwave and FM broadcast band coverage (OIRT band or the FM broadcast band commonly used in Western Europe, only for export sets).
The Selena B-212 is a portable set with a partly wooden cabinet, a carrying handle and a telescopic antenna mounted on top. Its dimensions are similar to contemporary Western sets from the 1960s and 1970s; it was produced in the Soviet Union for export to the West in exchange to foreign hard currency.
The set can be operated from six batteries or from the AC mains; the mains cable with an nonstandard plug is plugged into the back of the unit.
One switch turns on the AC power supply (∼), a second below it serves as the main switch. Two other buttons at left activate the automatic frequency correction (AFC) in the FM broadcast band and the dial illumination.
To the left of the speaker grille are the controls for volume and separate controls for treble and bass; the sound is pleasant thanks to the large speaker and the wooden cabinet. At the bottom right is the tuning knob. A rotary switch on the right-hand face of the set activates the turret tuner for the band selection; the selected band is displayed in a small window. The frequency is displayed on a horizontal dial with sparse marks. Apparently there are different dial variants, on my set the frequency marks are in MHz and metres, other variants have only the metres (impractical if you have looked up the transmission frequency in MHz or kHz), and instead of the frequencies station names in the medium wave range are printed, which takes up more space on the dial.
When buying a set, make sure you don't get one of the similar variants covering the OIRT frequency range that was common in Eastern Europe at the time; there's not much to receive in this VHF range of 64 - 73 MHz nowadays.
A small S-meter indicates the signal strength. Apart from a switchable AFC for the FM broadcast band, there are no other controls.
The Selena is easy to operate, very robust (my set, which I got for little money, performed flawlessly apart from some corroded contacts) and is a reliable performer in the shortwave bands. However, there is no BFO for single sideband reception, other features such as electronic frequency memories, etc. are nada… nada…
The set is equipped with semiconductors.
The set was apparently developed at VEF in Riga and produced by the Minsk Radio Works mainly for export in exchange for foreign hard currency. Various mail-order companies in Germany had it for sale at a relatively low price.
