Re: LF: sending EbNaut with SL on 137485.00 Hz

Domenico,  I saw some pieces of carrier and got a couple of all-asterisk decodes at 16 and 16:30 UT, but no real messages.

Thanks Markus for advices,

i'm workaround on the settings without success till now.

Some Ebnaut's  (13 char, 0.5s) again every 30' from 15:00U to 17:30U. This time with my traditional method i.e. ring modulator driven by EbNaut-TX with the  RDF phase locked loop. 

73, Domenico

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

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
