<p class="MsoNormal">Hi Bruno,<o:p></o:p></p>
<p class="MsoNormal">From a first iteration with the WGs we got a first set of questions:<o:p></o:p></p>

<ol style="margin-top:0cm" start="1" type="1">
<li class="MsoListParagraph" style="margin-left:0cm;mso-list:l2 level1 lfo3"><span lang="EN-US" style="font-size:11.0pt">We understand that Proxy-1 frequencies are organized in two chunks. One recommended covering channels 0-4, and one covering 5-9 channels.
Can missions use both hailing channels for either/or frequency chunk (mix up)?<o:p></o:p></span></li></ol>
<p class="MsoListParagraph" style="margin-left:72.0pt"><span lang="EN-US" style="font-size:11.0pt">Example: imagine a mission using hailing 0 and then frequency channels 5-8 for data transmission<o:p></o:p></span></p>
<ol style="margin-top:0cm" start="2" type="1">
<li class="MsoListParagraph" style="margin-left:0cm;mso-list:l2 level1 lfo3"><span lang="EN-US" style="font-size:11.0pt">Does 2095.1583 -2100.1583 MHz channel (2<sup>nd</sup> chunk, with the note **) require specific frequency coordination for approval since
it is a shared chunk? Should we reflect this with a note in CCSDS Prox-1 book? E.g., we allow the protocol to have all channels but put a caveat that is subject to SFCG frequency coordination
</span><span style="font-size:11.0pt">as per RES A26?</span><span lang="EN-US" style="font-size:11.0pt"><o:p></o:p></span></li><li class="MsoListParagraph" style="margin-left:0cm;mso-list:l2 level1 lfo3"><span lang="EN-US" style="font-size:11.0pt">For making the hailing channel as much as possible, we would like to avoid to filter the Bi-phase-L (SP-L/PM modulation). Is it feasible
for SFCG to consider to add an exception for the hailing channel to the mask in REC 41-1, in lieu that hailing channels are 2 ksps only?<o:p></o:p></span></li></ol>

<p class="MsoNormal">At its annual meeting in June, SFCG finally approved the SFCG Recommendation 42-1 on the frequency channel plan for in-situ lunar data relay satellites. As a result, SFCG also approved the attached liaison statement to CCSDS to support
your activities in updating the CCSDS Prox-1 protocol.<o:p></o:p></p>
