1. LF: 8270 Hz (score: 1): Author: DK7FC <[email protected]>; Date: Wed, 25 Feb 2015 20:08:10 +0100; Hi VLF, Ohohooo, i can see a signal on 8270 Hz in 47 uHz. Maybe Uwe is doing a new digital test? http://www.iup.uni-heidelberg.de/schaefer_vlf/DK7FC_VLF_Grabber.html 73, Stefan; /rsgb_lf_group-archives/html/rsgb_lf_group/2015-02/msg00260.html (9,308 bytes)

The transmissions are not visible on a spectrogram, merely an imperceptible in; /rsgb_lf_group-archives/html/rsgb_lf_group/2015-02/msg00261.html (8,865 bytes)

But i think it is to uncertain to claim something. With this SNR, if this is your signal, you could try 1 character E; /rsgb_lf_group-archives/html/rsgb_lf_group/2017-12/msg00161.html (9,468 bytes)

I'm still not set up to run EbNaut but now at 2100 UT have the carrier back on hopefully for another overnight run. 73, Dex On Mon, Dec 11, 2017 at 8:58 AM, DK; /rsgb_lf_group-archives/html/rsgb_lf_group/2017-12/msg00164.html (10,489 bytes)
