comments: Trouble shot MWD transmission failure. Worked mud pumps at different rates and different configurations while rotated and resiprocated pipe. Down linked tool to 3 bit signal density. Started with bit on bottom and reduced pump rate to keep tool in sync. Got good signal with valid drilling parameters.
