• Notes
• The radio model DongFeng 东风 714 receives broadcast 535 - 1605 kc. The IF frequency is most probably 465 kc. Data 2 mV/m, 20 dB (manual 03 = 14 dB), output 100 mW. Electric power consumption 电源消耗 at zero signal 零信号: is 14 mA, at max. output 80 mA. Loudspeaker impedance is 8 ohm. 1 diode. The manual 03 shows on page 163 the same documentation and schematic for DongFeng 东风 714 plus Huanqiu 环球 714, made by 北京市东风无线电一厂 Beijing Shi No.1 Dongfeng Radio Factory; Beijing. We assume the same case size and take it from there.
