这是hf至50兆各种模式的dx呼叫频率或者称为dx window,如果我们仔细研究一下，可以看出，不同的操作模式dx 呼叫频率都有一定的规定，并不是我们随意使用的。因为crsa并没有给出我们详尽的频段划分，因此喜爱做dx的朋友，一定要熟悉这些频率使用规定，对于做dx非常有价值，另一方面熟悉了这些约定俗成的规定，就不会无意识地干扰了他人的正常工作。由于文字很简洁，大家都能看懂，因此没有翻译。有条件的可以存到电台上，方便使用。
note: by tradition, 20m and up is upper sideband, 40m and below is lower sideband. an exception is the new 60m ham band -- use usb. this protocol came about as a matter of convenience in early ssb transceiver design and has remained to this day. and yes - you can operate either sideband legally where phone is allowed. and yes you can operate cw on the phone bands -- but best stay with the protocols. see url:
