Re: LF: ZEVS transmission at 1800BST (score: 1): Author: Stefan Schäfer <[email protected]>; Date: Sun, 08 May 2011 23:27:49 +0200; Hello Chris, Gerhard, ELF, I've also seen a stable trace at 82 Hz but not the frequency shifting transmission before. For some reasons there are various QRM levels here and i don't know the origin. N; /rsgb_lf_group-archives/html/rsgb_lf_group/2011-05/msg00022.html (11,427 bytes)

Very interesting....I'm also using Stefan's E-probe and on 9khz ist's very sensitive. My probe is more than 15m above ground and I'm also trying to receive the ZEVS-transmissions.

I set it up only this afternoon so I don't claim it to be optimised in any way - particularly the noise blanker. The FFT bin width is 10.17mHz with; /rsgb_lf_group-archives/html/rsgb_lf_group/2011-05/msg00400.html (11,238 bytes)

LF: ZEVS transmission at 1800BST (score: 1): Author: Chris Dillon <[email protected]>; Date: Sun, 08 May 2011 18:58:50 +0100; Hi all - ZEVS transmission starting at 1800 BST received at IO92vf using a 'Stefan' pre-amp with a 1m probe about 3m high. Still transmitting a constant carrier on 82 Hz at 1857 BST. Wonder if they Q; /rsgb_lf_group-archives/html/rsgb_lf_group/2011-05/msg00541.html (9,454 bytes)
