Comments :   ​Invest box pattern until NHC started driving. Pavone said take a RECCO at center then changed his mind after RECCO sent. Couldn't send VDM or delete RECCO.
Equipment : Arrived at first drop point on time at beginning of window. Went into 
holding pattern at this point while troubleshooting problems with the Load pallet. 
Per coordination w/Met Shop, tried 8 dropsondes at multiple altitudes and using 
all channels/frequencies...all sondes terminated between 22-27K ft. Had to RTB.

Did not turn on SFMR due to gradient over Gulf Stream.

SATCOM: Got RCVROFF about an hour in. Called CARCAH and switched to Ch. 42, no further problems.
