牡丹牌942、942-A、944型机,都是普及型四级便携式机。942机是由九只晶体管、二只二极管组成的超外差式收音机,它是通过实际调查和征求有关商业部门的意见后,设计定型的。该机体现了便携普及机的大机壳、大电池、大喇叭、低成本等特点,从而受到了广大用户的欢迎。一、主要性能1.频率范围:535~1605千赫。2.中频频率:465±5千赫。3.灵敏度:20分贝时不劣于1.5毫伏/米。4.选择性:不劣于14分贝。5.不失真功率:(失真度不大于10%)时不劣于150毫瓦,最大输出可达500毫瓦。6.电源电压:直流6V(一号电池四节)。
Peony brand 942,942-A, 944-type machines, are universal type four portable machine. The 942 is a super-heterodyne radio consisting of nine transistors and two diodes. It is designed and shaped after an actual investigation and solicitation of advice from the relevant commercial departments. The machine reflects the portable universal machine large chassis, large batteries, speakers, low cost and other characteristics, which has been welcomed by the majority of users. First, the main performance 1. Frequency range: 535 ~ 1605 kHz. 2. IF frequency: 465 ± 5 kHz. 3. Sensitivity: not less than 20 dB at 1.5 mV / m. 4. Selectivity: not inferior to 14 dB. 5 without distortion power: (distortion of not more than 10%) is not inferior to 150 milliwatts, the maximum output of up to 500 milliwatts. 6 power supply voltage: DC 6V (a battery four).
