Pity. Do you want to try again later tonight? That would probably imply rescheduling the following daytime sequence as well.
Exactly!
Update:

f = 8270.100000 Hz
Start time: 04.May.2017   21:00:00 UTC
Symbol period: 40 s
Characters: 3
CRC bits: 8
Coding 16K21A
Duration: 8h, 10m, 40s
Antenna current: 670 mA

(Set list length to: 239 in the first run)
This is an experiment using a low CRC value which gives a lower optimum list length. Let's see if it produces to many false decodes.


Probably that's a transmission for Paul only:

f = 8270.100000 Hz
Start time: 05.May.2017   05:30:00 UTC
Symbol period: 10 s
Characters: 100
CRC bits: 0
Coding 8K19A
Duration: 13h, 44min
Antenna current: 670 mA

Wow, you might end up using that fan as a helicopter to raise the antenna ;-)
Again, exactly! Because that may become necessary in the future. They are planning a safety inpection for July this year! In the worst case it will be the end of this setup here. So i'm pallning for any eventualities: http://www.xxl-modellbau.de/Multicopter_2
A good new project anyway...
