No way to guess suitable code settings without prior
experience or a measurement.

I recommend a 3 hour carrier, GPS locked tx and rx
to get hopefully a spike on a spectrum in 92 uHz.

Measure S/N and put that into

 http://abelian.org/ebnaut/calc.php

to play with the code settings to predict an Eb/N0
of say +1dB.
