1. LF: To DK7FC : measuring low levels RF current. (score: 1): Author: "F6CNI - Andy - JN19QB" <[email protected]>; Date: Fri, 23 Oct 2015 14:53:29 +0200; Helo Stefan, For info, here I am using a MFJ 834 RF Ammeter. It is working well on MF band, it just need to be first re-calibrate on MF band (only one variable resistance to adjust) using a low power; /rsgb_lf_group-archives/html/rsgb_lf_group/2015-10/msg00351.html (19,436 bytes)
2. Re: LF: To DK7FC : measuring low levels RF current. (score: 1): Author: DK7FC <[email protected]>; Date: Sat, 24 Oct 2015 00:03:38 +0200; Hello Andi, Thanks for the info. What does this amperemeter cost? I think i would know how to build an amperemeter for 100 mA FS. However my ranges are 5A / 10A / 20A :-) I'm directly measuring the a; /rsgb_lf_group-archives/html/rsgb_lf_group/2015-10/msg00361.html (21,498 bytes)

Just to make it clear: I certainly know how to measure a RF current on DC to HF and above :-) Higher currents? Well, 20A is fine for me, otherwise the d; /rsgb_lf_group-archives/html/rsgb_lf_group/2015-10/msg00364.html (25,239 bytes)
