  • Notes
  • The models Baodeng 宝灯 7104 and 710-5 show the same technical page incl. schematic. Behind the number 710 it shows a 4 over a 5 and we presume that this is meant for model 710-4 and 710-5. Frequency range 频率范围: broadcast band 525 - 1605 kc. Sensitivity 灵敏度: < 1.5 mV/m. Selectivity 选择性: > 14 dB. 不失真功率 not distorted audio output : 大 于Larger than 250 mW.. Electric power consumption 电源消耗 at zero signal 零信号: is not given. The IF 中频频率 is most probably 465 kc. Loudspeaker impedance is 8 ohm. 2 diodes.
