众所周知,微波传送广播节目在质量上比短波传送高得多。但微波传送也还存在电路不够稳定的问题。特别是瞬间中断次数比较多(一般中断时间为3～5秒或10多秒),中断时间无规律等缺点,对广播危害比较大。为了弥补这一缺陷,我们根据微波电路传送广播的特 It is well known that microwave delivery radio programs are much higher in quality than short wave delivery. However, microwave transmission also has the problem that the circuit is not stable enough. In particular, the number of momentary interruptions is relatively large (usually, the interruption time is 3 to 5 seconds or more than 10 seconds), and irregularities such as irregular interruption time are more harmful to broadcast. In order to make up for this flaw, we send radio specials based on microwave circuits
