2. LF: ref LD30 (score: 1): Author: "mal hamilton" <[email protected]>; Date: Fri, 14 May 2010 19:35:46 +0100; Well, I am getting 15v sine wave into a 50 ohm DL with the LD30, this looks promising. All I need now is a 500W audio amp suitably matched into 50 ohms. I prefer to keep a standard 50 ohm system for; /rsgb_lf_group-archives/html/rsgb_lf_group/2010-05/msg00116.html (9,689 bytes)

Re: LF: ref LD30 (score: 1): Author: "mal hamilton" <[email protected]>; Date: Sat, 15 May 2010 13:34:02 +0100; Stefan My Loading coil inductance at 137 is around 0.5mH therefore at 9 kHz it should be roughly 116 mH. Not such a big coil in my case. Tnx info de Mal/g3kev -- Original Message -- From: Stefan.Scha; /rsgb_lf_group-archives/html/rsgb_lf_group/2010-05/msg00458.html (12,272 bytes)

Re: LF: ref LD30 (score: 1): Author: Stefan Schäfer <[email protected]>; Date: Sat, 15 May 2010 13:52:59 +0200; Mal, I assume you know your antenna capacitance so you can easily calculate your needed inductance. Or, if you know your L for 137kHz, it will be about (137/9)^2 at 9 kHz! Stefan/DK7FC Am 14.05.2010; /rsgb_lf_group-archives/html/rsgb_lf_group/2010-05/msg00486.html (10,801 bytes)
