Dear Andy, LF Group,

So by continuously looking at repeated message, the effective
bandwidth will get lower by the average of the number of times it has
been repeated.   Two repeats 3dB or half BW, 4 repeats 6dB , 8
repeeats 9dB  etc etc

Does this seem about right ?


Well, I cannot claim any expert knowledge, but I'm sure that must be the intention. Presumably the limit to which this can be done is determined by the ability of the decoder to successfully detect the pseudo-random sequence. I guess it has to do this separately for each 96 second message in order to get the carrier phase for that message.

Cheers, Jim Moritz
