BX2AF DIY


Taiwan Number 1  ,有圖有真相

Thanks BV2BJ,
WOW!! "DIY001" Is it a vacuum tube or transistor based transceiver ? Some of us may see the vacuum tube based audio amplifier, but it is not easy to see a vacuum tube based RF transceiver.

During worked in broadcast station to see the AM/FM transmitter with output power about 10KW, and they are all done with solid state amplifier now. The elder engineer still memory the vacuum tube based AM/FM amplifier -  not fancy but long life.

In this forum, I see the activity introduction over 2011/5/31 about BX2AF OM

ps. Just got my class 2 station license today which issued with a Taiwan-made HT, and I will re-register with callsign BX3AAQ(阿~Q).

For the Norcal 40A, some university in USA select it as a lab project and course study material.
In follow course link, the NC40A is well studied in different stage.

The course hand-out have a good balance in theory and experiment. For the home-brewer or qrper, it should be a good material.

各位先進們好,
看到一些國外的業餘無線電玩家或店家有製作antenna tuner, power meter, swr meter 甚或 antenna analyzer的套件,在此想到是否能將這些function結和如,
Automatic Antenna Tuner+Power/SWR Meter+Antenna Analyzer(option)
給QRP及HF波段使用,這個DIY project的想法是否可行及具實用性 ?
現下想利用以下的chips AD9834 DDS, AD8307 LOG AMP, PIC uC with ADC, 2-line LCD panel著手
