[quote=vr2ung]什麼是ale?

ale正常的解释为自动链路分析系统。它主要短波ale电台,自动链路建立,链路质量分析等等;主要目的是自动分析、监测当前可用的muf/luf最高/最低的可使用频率,从而保障通信。

原理是主属台通过呼叫协议建立联系后, 首先在双方约定的各信道上进行由主台发、属台收的扫描探测。探测完毕,双方回到正常状态。通过呼叫协议建立联系后,属台把主台到属台的可用信道的质量分析结果报告给主台,然后在这些信道上进行由属台发、主台收的信道探测。探测完毕,双方回到正常状态。主台根据信道质量分析结果,即可建立跳频频率表,最佳、最可靠的通信频率。美国、澳大利亚军用短波通信用的比较多。有了带ale电台的帮助,我们不用天天看预报,看哪个频率可用,是否适合做dx, 实践表明,这套系统的应用可以保证短波全年98%以上的开通率。

看了上面的链接,感觉现在和传统意义上的ale不同了,它需要短波基地台、移动台、固话、移动手机用户、计算机互联网络都进行测试、分析,建立一套应急通信网络,是一种广义上的ale。

个人的想法还是全世界、起码国内的爱好者(数以万计)的短波台,都加装ale系统(技术很成熟,成本也不高),只要我们24小时开机,无人值守也可以,我们其中的任何一个人都可以遥测每个电台、在从低到高,不同频率,实时发回的信号报告,进行分析后,就可以知道当前的最佳呼叫频率,自动建立链路;同样我们可以实现群呼,个别选呼,实现与u/v段对讲机的相同的功能。只要有人守听,我们可以像打电话一样(数字静默、数字选呼)任何一个地方的人。上述功能对中国这样一个多灾多难的大国来说,建立应急通信体系特别值得研究。

当然,ale的实现不仅需要改造现有的短波设备,还需要自动天调调谐系统、宽频天线,这有这样才能保证各个频率,信道的开通,各个电台建信道的同步地建立。

应当是一项庞大的系统工程,但是无论怎样还是有其实际意义的。

How to buy UGG sheepskin boots
how to buy ugg sheepskin boots?
everyone who wear the ugg sheepskin boots will get many benefits. ugg boots are made to be worn barefoot as they will form to your feet and provide natural arch support. when buying a pair of sheepskin boots or ugg boots (premier brand in luxury and comfort footwear), there are many things to look for:
first of all, you must make sure your sheepskin boots are actually made out of 100% authentic sheep skin. some manufacturers use cheap substitutes such as gluing synthetic wool on to cow hide. these imitation sheepskin boots come at a cheaper price tag, but unfortunately the less expensive alternatives may cause skin irritations, encourage bacteria growth, wear down, tear quickly and noticeably less comfortable. http://www.shoppingugg.com
when buying sheepskin boots, make sure they are manufactured from quality australian merino wool. australian merino sheepskin boots are considered the best material for making sheepskin boots and it also ensures that you will be able to use them for many years. authentic wool also allows your feet to breathe and help reduce feet sweating. merino sheep skin is by and large thicker and much more durable than other kinds of sheep skin, which helps your boots keep their shape as well as resist wear and tear. by purchasing sheepskin boots made from merino wool and sheep skin, you will be guaranteed that not only will they be the most comfortable pair of sheepskin boots you'll ever own, but they will also last for a long time to come.
i have included some links if you would like to learn more about sheepskin boots or youwant to know where can buy some ugg boots - australia markets the premier brand in luxury and comfort. their many products fit into your every day life offering you products that are fashionable, comfortable, and attainable.
ugg boots have been made and worn in australia/china for over 50 years and "ugg" is not associated with any brand or style of sheepskin boot. so if your looking for real australian made ugg boots look no further than shopping ugg see our full range of cardy ugg boots , classic short ugg boots , classic tall ugg boots , metallic ugg boots , sundance ugg boots and now even new mini ugg boots then you can find all the love from australia right here.
