Re: VLF: EbNaut message announcement @ 5170

Excellent signal indeed. The spread-out EbNaut message and your DFCW-90 greetings are perfectly visible on the DL0AO grabber:

73, and thanks for the nice activity!

Yay! Now at 9:40, we are getting strong peaks at DL0AO: 25 dB in 3.8 mHz on E-field, and 20 dB on the E-W earth loop. 

Good luck!

73, Markus

VLF,

The carrier is now running since 09:31 UTC at 5170.1 Hz. Actual antenna current is now 2.81 A at 545 W RF power. The EbNaut message will start at 10:30:00.3 UTC.
Measured DC resistance was just 55.4 Ohm today, the lowest value ever measured.

73, Stefan

Hi VLF,

In a few hours, an EbNaut transmission is planned on my ground loop antenna. TX frequency will be 5170.1 Hz. A 1 hour carrier transmission will be done earlier.

The exact start times will be announced soon.

Message:
f = 5170.1 Hz
Start time: 16.MAR.2019  ??:?0 UTC
Symbol period: 2 s
Characters: 14
CRC bits: 14
Coding 16K21A
Antenna current: 3 A
Duration: 01:02:56 [hh:mm:ss]

Reports are requested and very welcome. It will be the strongest signal radiated from this antenna at this frequency so far, maybe even the strongest signal on that band (58 km).

73, Stefan
