Re: LF: VLF/ULF activity weekend 21th/22th

[Markus Vester <markusvester@aol.com>]

Hi Vinny,

I'm about to change over the coil from LF to VLF, and if all goes well I'll attempt to send a 8270.0025 Hz carrier for a couple of hours already this evening. It would be great if you'd catch that, but don't expect too much as my radiated power will be at least 12 dB less than Stefan's new coil.

Best 73,
Markus (DF6NM)

Wow,

what a broadcast schedule!

Probably there is too much noise at my QTH for recieving you on 2970 Hz Stefan, but grabbers are running (https://qrz.com/db/DL6II). Maybe I can improve the RX a bit this evening.

Hopefully Markus is able to leave a trace on 8270 Hz here nr Cologne.

I see I have to build a /p-RX-setup in the near future...

Good Luck es 73
Vinny, DL6II

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
