Radio Maintenance EPR Bullets


- Traced problem on faulty alarm interface panel to burned resistor, replaced, restored monitoring capability

- Identified downconverter automatic switch failure, traced to switch and repaired, restored redundancy

- Isolated Terrestrial Critical Communications Circuit (TCCC) outage to loss of crypto synchronization; reloaded keying material; restored communications circuit before circuit was logged out by technical controllers

- Utilized existing equipment and spare parts to assemble rack--saved work center $16K in material costs

- Rebuilt intercom cord/mic switch--2 hour fix accomplished in one--army special forces mission flown to Iraq on time

- Performed complicated frequency converter and amplifier frequency response and gain alignments--Enabled 100% operational redundancy and directly responsible for the low satellite link failure rate

- Oversaw long overdue and complicated preventive measurement inspections (PMIs) on terminal equipment
-- Supervised and trained seven technicians on measurements, adjustments, lubrication, and alignments
-- Actions completed well before the eight hours authorized downtime; quickly restored service to users

- Quickly identifed jamming source and prevented damage to the West Pacific satellite
-- Isolated upconverters from computer control and attenuated their output when the terminal processor seized control and raised transmit power high enough to disrupt all communicatons on the satellite

- Valued trainer; trained six personnel on high power amplifier tuning methods, adjustments, and anomalies
-- Improved maintenance capability and eliminated unscheduled outages due to misalignments

- Traced problem on faulty alarm interface panel to burned resistor, replaced, restored monitoring capability

- Updated workcenter's master equipment inventory listing (EIL) and preventive maintenance schedule -- review increased inventory accuracy and improved maintenance of new assets at USCENTCOM by 40%

- Tested and identified a faulty U-link used to patch circuit trunks between the Digital Communications Sub-System (DCSS) and Operations Van--prevented future intermittent communications interruptions

- Performed annual modem characterization procedures; verified equipment performed within optimum operational levels; ensured compliance with Defense Information Systems Agency standards

- Provided valuable assistance to Tobyhanna Army Depot maintenance team; replaced azimuth motor electric brake assembly; enabled depot team to proceed with troubleshooting of autotrack failure

- Isolated link outage to autotrack failure; slewed antenna to restore tracking to reestablish satellite link
-- Restored communications in less than one minute; contributed to terminal's over 99% reliability rate

- Identified downconverter automatic switch failure, traced to switch and repaired, restored redundancy

- Knowledgable on the Switch Multiplexer Unit (SMU); trained personnel on programming
-- Responsible for successful participation in site's first tactical provision of switched DSN resources

- Isolated cross-talk noise problem on site's tactical interface panel; identified inadequate shield grounding on signal cables; corrected long-standing discrepancy; restored interface capabilities with tactical systems

- Engineered and established first-ever interface between two proprietary video teleconferencing systems
-- enabled SOCOM planners to communicate in real time voice and video to AOR commanders

- Tested and identified a faulty U-link used to patch circuit trunks between the Digital Communications Sub-System (DCSS) and Operations Van--prevented future communications interruptions

- Established satellite link with JCSE during Exercise BRIGHT STAR '00; tested equipment, circuit, and carrier path for reliability, provided error-free link, ensured terminal prepared for mission readiness

- Isolated Terrestrial Critical Communications Circuit (TCCC) outage to loss of crypto synchronization; reloaded keying material; restored communications circuit before circuit was logged out by technical controllers
