Description
The Cora 2 is a miniature pocket radio for medium waves made by Electronica in Bucharest, with the same circuit and characteristics as the Cora 1 S 700 T and a differently decorated case [1].
Tehnoton in Iași also made it in 1974–1977 [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].
