you have a point. We could change the main body text to read:</span><span style=" font-size:12pt;font-family:Times New Roman">
</span></p>
<p style="margin-top:0px;margin-Bottom:0px"><span style=" font-size:12pt;font-family:Times New Roman">The
ranging signal chip rate shall be frequency coherent with the uplink carrier
as given by the following expression (for <i>k</i>=6 and <i>l</i>={1,2,…,12,16,32,
64 or 94</span><span style=" font-size:10pt;font-family:Times New Roman">
</span><span style=" font-size:12pt;font-family:Times New Roman">} or for
<i>l</i>=2 and <i>k</i>={8,9, or 10}). <br>
The value l=94 shall only be used for Ka-band4 uplinks. See also an example
of available chip rates in annex B. <br>
</span><span style=" font-size:10pt;font-family:Arial"><br>
I think it fixes both issues you raised. If Tom agrees, we can proceed
with it.</span><span style=" font-size:12pt;font-family:Times New Roman">

the CWE project related to this update is under
