用单边带接收机接收副载波移频信号,按技术说明书操作就可以了。而用单边带接收机接收直接移频电传,说明书没有讲,各地所用方法也很不同。一般说来,用单边带接收机收直接移频电传并不难,但要做到接收高质量,却并不容易。例如开关放置不当,调整不准,信号不稳或信噪比小,都会使电传机变字。虽然用无线移频方式通信,难以做到一字不变,但争取最好的接收效果,是我们通信人员义不容辞的责任。我们体会将机器调至最佳
With single sideband receiver to receive subcarrier frequency shift signal, according to the technical manual operation on it. The use of single sideband receiver to receive direct frequency shift telex, the manual did not say, all the methods used are also very different. In general, it is not difficult to receive direct frequency-shift televisions using a single-sideband receiver, but it is not easy to achieve high quality reception. For example, improper switch placement, adjustment is not allowed, the signal is not stable or small signal-to-noise ratio, will make the teletype change. Although the use of wireless frequency shift mode of communication, it is difficult to be unchanged, but for the best reception, it is our bounden duty of communication personnel. We realize the best machine
