Re: VLF: EbNaut at 8270.003

[Riccardo Zoli <riccardozoli80@gmail.com>]

Hi VLF,

Thanks Stefan and Markus for your detailed reports.

Ok Stefan, I'm agree, we can try: a new message started at 1600 UTC, same scheduling for the following transmissions.

QRG: 8270.003 Hz

6 ch.

25 sec./sym

coding 16K21A

CRC 15

duration 7h 53' 20"

antenna current about 600mA

GL and thanks again for your patience :-)

P.S.: now there are some thunderstorms nearby, I hope I won't have to stop the TX :-/

All the best

Here is a corrected and continued list of the results of your transmissions:

PS: You could try to transmit your full callsign for example. It would work here. A higher challenge.

Hi Riccardo,

Now i finally got your message, see attachment. The transmission of tonite 0 UTC was very strong, as i would usually expect.
It must have been the QRN. And now since know the message i can look for the S/N or Eb/N0 of each of your transmissions:

Date	Eb/N0 [dB]
09.May_08:00	-1.3
09.May_16:01	-6.1
10.May_00:00	-4.9
10.May_08:00	-6.8
10.May_16:00	+0.9	decoded
11.May_00:00	+7.9	decoded

73, Stefan

30 sec/sym.

coding 16K21A

CRC 27

Thanks for reports, as usual...

All the best
