Hi Paul,

The QRN is amazingly low these days at day-time. Let's try to do the 100 
character experiment this weekend. With some luck, just 2 days could work?

*f = 6470.1000 Hz
Start time: 07.October.2017  06:00:05 UTC (daily)
Symbol period: 7 s
Characters: 100
CRC bits: 8
Coding 8K21A
Duration: 9h46min08sec
Antenna current: 300 mA*

A 7 second symbol length is a bit strange but i think it makes no sense 
to start before 6 UTC and i need to change the settings before the night 
transmission begins at 16 UTC. Also the start time is strange but once 
Markus mentioned that SpecLab orients to integer multiples of 7 seconds 
starting from 00:00:00 UTC. I will check if the transmission worked well 
from a recording from the tree...

Busy days here...

73, Stefan
