Hi Stefan,

will try to reply in the second half-hour slot. Same parameters, except start time 21:30:00 + 0.3 seconds.

73, Markus

First transmission received ok by the autodecoder:
http://df6nm.darc.de/opds/ebnautresults.txt
Optimum starttime appeared around +0.2 s, compatible with expected SpecLab delay.

Best 73,
Markus. (DF6NM)

PS: The message is transmitted from a SpecLab instance. So you need to consider the +0.3 second time offset, which is relevant at that symbol length. Furthermore there is some uncertainty if the transmission starts at the exact second. It could happen that it starts 1 second to late. We will see what happens.

Hi LF,

I'd like to try some EbNaut transmissions tonite. Maybe someone is some distance is interested to detect them?

Here is the program:

f = 137.465 kHz
Start time: 11.NOV.2018  19:00 UTC (hourly, until including 7 UTC)
Symbol period: 1 s
Characters: 21
CRC bits:
16
Coding 8K19A
Antenna current: 4 A
Duration: 21:20 [mm:ss]


Reports welcome.

73, Stefan
