  • Notes
  • The radio model Huanqiu 环球 901 ("Worldwide") has the following key features 主要性能: Frequency range 频率范围: broadcast band 535 - 1605 kc and SW 3.9 - 12 mc. Sensitivity 灵敏度: < 1.5 mV/m. Selectivity 选择性: > 20 dB. Set audio output 额定功率: 150 mW (300 mW). Electric power consumption 电源消耗 at zero signal 零信号: is 18 mA, at max. output 65 mA. The IF 中频频率 is most probably 465 kc. Loudspeaker impedance is 8 ohm. 2 diodes.
    There is probably an error in the schematic of manual 02, page 170/171 to show BG6 as 3BX31B and also to mention 3AX81A, PNP or NPN is not possible without design change.
