发帖数: 1197 | 1 增加电感系数吧，这是低频波段了。AM最低的频率也是200kHZ了吧？
三个波段，
Long wave is 153–279 kHz, with 9 kHz channel spacing generally used. Long
wave is only used for radio broadcasting in ITU region 1 (Europe, Africa,
and parts of Asia), and is not allocated elsewhere. In the United States,
Canada, Bermuda, and U.S. territories, this band is mainly reserved for
aeronautics navigational aids, though a small section of the band could
theoretically be used for microbroadcasting under the United States Part 15
rules. Due to th... 阅读全帖 |

发帖数: 9094 | 14 如何提高英语听力水平? Make it a fun process!
Listening comprehension is another area which requires a lot of attention
from English learners. Intrinsically your ability to understand what goes
into your ears would help shape what comes out of your mouth after all the
information is processed within your brain. Therefore, there is a positive
feedback loop between the listening and speaking skills of an English
learner. For example, a good listener would easily and correctly understand
a speaker’s main poin... 阅读全帖 |

发帖数: 1 | 15 說到業餘愛好，除了釣魚我還玩業餘無線電，如果喜歡聽收音機尤其是短波的，我推薦
Icom R-71。再配上一個長線天線就不錯了。業餘無線電我搗鼓了快6年了，從自己設計
製作shortwave，VHF/UHF/microwave發射天線，到設計一些小電路，自己做放大器，自
己改電台，這個愛好沒有盡頭啊，而且花銷很大。目前我的電台cover從3.5MHZ一直到1
.2GHZ，下一步準備再往上去10 GHZ。
有時候沒事還做做吉他功放。
這是去年冬天休漁的時候自己做的2W的電子管吉他功放，前級用12ax7，Phase
inverter用第二個12ax7管子，功放部分用的是12BH7的管子，音色很不錯。 |

发帖数: 9 | 18 AFAIK, VOA only broadcasts overseas. It's a pure propaganda machine of
the US government.
If you are REALLY interested, you can go to their web site and listen to
some audio files (www.voa.gov). But being a former listener myself when I
was in China, I never want to listen to it again. Just imagine CNN in its
extreme.
It is a good source to learn English, though. I can still vividly remember
how I tuned in using my old shortwave radio and how I enjoyed the
authentic American English. Boy was it |
