The Drake DSR-2 is a desktop shortwave receiver covering 0.1-30 MHz. It features double/triple conversion receiver system, 6/2.4/1.2/0.3 kHz filters (optional filters available), and Nixie tube display. Image rejection is ≥ 60 dB below 10 MHz and ≥ 50 dB above 10 MHz. The audio output is 2 W @ 5% THD. Frequency stability is less than 200 Hz per 8 hour at 0-40 °C and ±10% variation in line voltage after 0.5 hour warmup. Tuning steps are 10 / 1 MHz / 100 kHz. The IF output frequency is 50 kHz. The receiver includes BFO, noise blanker, and AVC (Automatic Volume Control). It weighs 7.7 kg and requires 120/240 V AC ± 10% single phase 50~420 Hz power. Dimensions are 140 × 340 × 380 mm.
