Description
The Pescăruș S 725 T is a pocket transistor radio for long and medium waves, made by Electronica in Bucharest from 1972 [1]. Everything except the loudspeaker and the earphone jack is on a single printed-circuit board [1]. A companion pocket set for medium and short waves was the Alfa [1].
Tehnoton in Iași also made it in 1974–1982 [2].
In the source table, sensitivity is given on medium waves for 50 mW output and a 20 dB signal-to-noise ratio, selectivity for a signal ±9 kHz (AM) or ±300 kHz (FM) away, and output power at no more than 10% distortion [1].
