我院于1987年11月研制成功一种微型话音保密器,可以方便地插入现有的手持或车载电台,不必改变原电台的电路,也不会影响原电台的电性能与通信距隔。其加密效果可使一般窃听者莫明其妙,而解密恢复的话音自然度与可懂度令人满意。该保密器的接口电路灵活性好,可与各种电台相连,已在电子工业部七一一厂生产的150MHz电台,公安部某研究所生产的150MHz电台,日本T R 2500电台上试用成功。该保密器对于改
In November 1987, our institute successfully developed a miniature voice confidential device that can be easily inserted into an existing hand-held or car radio without changing the circuit of the original radio or affecting the electrical performance and communication distance of the original radio. The encryption effect can make ordinary eavesdroppers inexplicably, and decryption and recovery of voice natural degree and intelligibility is satisfactory. The interface circuit of the security device has good flexibility and can be connected with various radio stations. It has been successfully tested on 150MHz radio stations produced by the 71st Factory of the Ministry of Electronics Industry and 150MHz stations of a certain research institute of the Ministry of Public Security and Japan T R 2500 radio station. The security device for change
