I did add it up.  It does fit.

Let me try again.  There are 5 types of sentences.  Each second has 1 each 
except for GPGSV which has 3.  So there are 7 sentences each second.  Back of 
envelope.  7 sentences times 100 bytes per sentence times 10 bits per byte.  
That 7000 bits, well below 9600.  (The 100 bytes/sentence is way high.)

> Well, without a time frame not useful.

I sent a typical sample a few messages ago.  It had time stamps.  Would you 
like more?

I just put a scope on it.

PPS pulse is 4 ms wide.
Serial port is active for about 1/2 second, idle for the other half.

The serial stuff starts about the same time as the PPS.  Sometimes it's a few 
ms before the PPS.  Earliest I've seen is 7 ms before PPS.

These are my opinions.  I hate spam.
