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


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
