VLF: New experiments on 17.47 kHz planned...

[DK7FC <selberdenken@posteo.de>]

Hi VLF,

For this week, i'm planning to start with new experiments on 17.47 kHz, 
where i have a (renewed) special permission to transmit.
So far the best results were a prooved carrier detection as well as a 1 
character EbNaut decode by Edgar from Tasmania (VK7).
The first goal will be to determine the best time (start time and 
length) on the path for this season. We have a usable path for about 2 
months centered on our autun/spring time (21st SEP).
The Signal will be exported by SpecLab to simple txt files containing 
the FFT data. This allows stacking, which will be required to get some 
S/N at all. A reasonable stable path is essential during the 
transmission time. All this will be determined by running some carrier 
transmissions, a few hours per day, starting about 16 UTC.
When knowing the time to try we will attempt to transfer a 2 character 
message and then even longer messages. 5 characters would be realistic i 
think, with some luck and good propagation and low QRN on the RX site...
More soon.

73, Stefan
