Hi Markus,
inadvertedetedly i set the symbol rate to 40s. 8K19A, CRC16 starting 8
UTC today.

Hi
Stefan,
it looks like the final EbNaut transmission lasted longer than
expected, ending around 14:50 UT. One possible explanation could
be that the 7 char message was inadvertently also encoded with 21
instead of 16 bits CRC. Hope that you have still gathered enough of
the signal...

Betreff: LF: VLF/ULF activity weekend 21th/22th
VLF,
ULF,
This weekend there will be some activity on VLF and ULF!
I'm running my next experiment on 2.97 kHz, my goal is to reach a 140
km distant location in France, JN38OO.
During that time (recording in F/ starting staurday arround 10 UTC) i'm
recording the spectrum from 0...12 kHz with a loop pointing to 30/210
deg. It is a very quiet location.
I invited DF6NM and DJ8WX to transmit on 8270 Hz. I guess that Paul,
SQ5BPF and RN3AUS as well as DF6NM and DK7FC are watching. Of course
everyone is invited to transmit and receive. Transmit stations should
announce their time/frequency here, to avoid any collisions. I am only
transmitting on 2970 Hz and i expect there will be no one else.
My transmission plan is:
Friday, 20th:
8...17 UTC carrier on 2970.005 Hz at 150 mA antenna current.
Saturday, 21th:
8...17 UTC carrier on 2970.005 Hz at 150 mA antenna current.
17 UTC...8 UTC: DFCW-10800 on 2970.005- 2970.000_ Hz (each dash takes
3h, each break takes 1h). Message: 'F'
Between each break (20...21, 0...1, 4...5 UTC): EbNaut, 8K19A, 10s,
CRC21, 1ch on 2970.000 Hz
Sunday, 22th:
8 UTC: End of the DFCW transmission
8UTC: EbNaut 8K19A, 32s, CRC16, 7ch on 2970.000 Hz
13:24:16 UTC: QRT.
More details soon...
73, Stefan
