This will require the installation of breakout boxes and strip chart recorders. <\/p>\n \u2018The UHF system will have to be powered up and cycled through the different modes. At the completion of the testing a SCAN retest will be required on all demated pins. <\/p>\n \u2018Paper is currently in work to demate the connectors and install the breakout boxes. We will need help from the repair depot (JSC) to determine how much current should be expected on each pin so we can size the fuses in the breakout boxes correctly.\u2019<\/p>\n The Noon Board meeting \u2013 which rarely actually occurs at noon \u2013 met again on Friday morning (11am), following yesterday afternoon\u2019s discussions, and cleared the UHF radio to fly as-is.<\/p>\n Presentations from that meeting will be summarized later today.<\/p>\n Pad Flow: Final pressurization was completed last night at 02:22 (local).
