Hi Domenico,
 
on the opds spectrogram there are currently two discrete peaks on 137484 and 137486 Hz, plus some weaker ones spaced at 1 Hz intervals. Thus it seems that you are modulating with a regular "101010..." sequence rather than an EbNaut message?
 
Best 73,
Markus

Betreff: LF: sending EbNaut with SL on 137485.00 Hz

Hello LF,

i want to test this Wolf's Spectrum Lab feature

http://www.qsl.net/dl4yhf/speclab/EbNaut_Rcvr.htm#sending_ebnaut_with_SL

and i'm currently sending an EbNaut message on LF (13 characters,
0.5s/bit, 8K19A) each XX:00, XX:30. Last transmission at 12:00 UT

I'm using a non-linear PA so i want to check if SL MSK modulator can help.

I want also check if, using SL scheduler, there are no delay in the
activation time of the EbNaut sequence.

Thanks for the attention.

73 and good we.

Domenico, iz7slz
