S* Nothing "I put up a 200 foot antenna between two trees over my house, and tuned to a 50,000 watt station about 30 miles away, and now I get 175 microamps of current through my meter." It is almost nothing but more than zero. S* |

It is almost nothing but more than zero. S* You should put the meter in series with the diode or the earphone, not in series with the antenna or the earth. In the diode and in the earphones you have direct current that the meter will measure, in the connection to the antenna and the earth, you have radio frequencies that the meter will not measure correctly. -- Alejandro Lieber LU1FCR Rosario Argentina Real-Time F2-Layer Critical Frequency Map foF2: http://1fcr.com.ar |

Stokes drift and Tesla's electric waves are reality. Heaviside's compilations (TEM) are funny. S* |

... where should flow the electrons through the diode? The diode (plus leads) is much longer than the total movement of the electrons at RF. Exactly how many electrons are "flowing" through the diode during each RF cycle? -- 73, Cecil, w5dxp.com |
