Re: LF: To all VLF transmitters

[Markus Vester <markusvester@aol.com>]

The carrier from Nuernberg went off at 22:30.

Sat 2017-09-16:
11:28 - 13:56   4470.0025 Hz
15:01 - 18:15   8270.0025 Hz
18:48 - 22:30   8270.0025 Hz

Stefan is still active on 8270.005 Hz.

73, Markus

Today from 11:28 to 13:56 UT, I've sent a carrier from here on 4470.0025 Hz (170 mA). Then I reconfigured the coil assembly, and since 15:01 UT I'm joining Stefan on 8270.0025 (370 mA).

Best 73,
Markus (DF6NM)

Hi Luis, Mike, VLF,

A carrier is now running since 21 UTC on 8270.005 Hz. I decided to use the large coil, so i can run more antenna current. The antenna current is now 600 mA, a 6 dB stronger signal than planned.

I intend to run it for > 24 hours so tomorrow it is the time for you to watch your spectrogram(s).

73, Stefan

PS: Luis, it would be a first detection of VLF in Spain!

Will be interesting to have a signal in the 36km band, Stefan

 

I'm also running my grabber at 8270.007 with SpectrumLab and 1pps sync

The 11904 Alpha is also monitored. Unfortunately still much noise in the VLF band

but let's try the 47uHz FFT

 

BTW. Signal stopped last night
