Thanks, Paul=2E

Congrats to S= tefan and Markus=2E

The EbNaut Sender is prepared for = length 5, retaining period 30=2E
But: this afternoon the sky suddenly turned = from blue to dark grey, so possibly the TX stays off=2E

We will see=2E

Uwe,

=2E=2E=2E me too ;-) I was actually surprised ab= out the successful decode because the nighttime carrier was well visibl= e in Heidelberg but not at all in my spectrogram=2E

<= font face=3D"arial" size=3D"2" color=3D"black">Anyway both our decodes = were close to the limit, so for the next step I would suggest= to try 5 char but stay with 30 sec symbols=2E Due to the FEC and = CRC overhead, going from 3 to 5 characters (1=2E667 x payload= ) will increase the total time only by a factor of = ;1=2E23 so we already loose 1=2E32 dB sensitivity=2E Shortening th= e symbols from 30 to 20 seconds would cost another 1=2E76 dB=2E<= /div>

Thanks = for the test!

All the best,
Markus (DF6NM)

Hello Uwe,

Thanks for the VLF transmis= sion=2E No problem to decode the message! See attachment=2E
If Marku= s can decode and no other station wants to try, maybe we can try 20s sy= mbols and 5 characters, your callsign for example :-)

As you pro= bably saw, i saw your carrier on 8269=2E99 Hz in my 6000 window in the = city but not in the forest=2E Either it is a propagation phenomenon tha= t i don't understand yet or there is still something wrong with the dri= ft calibration=2E I will today go on the tree again to re-configure the= GPS-module and see if this makes a difference=2E=2E=2E

73, Stef= an
