In this particular situation, using Power SDR and Joe’s web based directions, one should set Penelope/Pennylane as the “master” clock source and set Mercury as the “slave” clock recipient. It is necessary to link the two modules via the LVDS interface. In the case of the Mercury module for this application, <u>do not</u> apply the jumpers on J5 (GPIO). Those jumpers are only needed for multiple Mercury applications, not this application.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>What is accomplished with this modification?
