Re: LF: sending EbNaut with SL on 137485.00 Hz

[Markus Vester <markusvester@aol.com>]

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.
