1. LF: Re: Re: Sound Card mic Impedance (score: 1): Author: "Ken" <[email protected]>; Date: Thu, 16 Dec 2010 22:05:14 +0100; Hi Clements. Are you sure, shunting a 50 ohm resistor with 4k ohms reduces it down to 49.38 ohms or am I missing something?. 73.

2. LF: Re: Re: Sound Card mic Impedance (score: 1): Author: "James Moritz" <[email protected]>; Date: Thu, 16 Dec 2010 23:37:24 +0100; Dear Ken, Clemens, As I recall, Ken is using a HF wire as a VLF RX antenna. The LF/VLF source impedance of such an antenna is basically the capacitance of the wire in series with some loss resistance; /rsgb_lf_group-archives/html/rsgb_lf_group/2010-12/msg00159.html (13,827 bytes)
3. LF: Re: Re: Sound Card mic Impedance (score: 1): Author: "Ken" <[email protected]>; Date: Thu, 16 Dec 2010 22:06:59 +0100; Clements. The filter will be terminated with an onboard 50 ohm resistor. 73.
