## Discrepancy

DURING ANNUAL INSPECTION, PERFORMED ELT INSPECTION IAW FAR 91.207D, AND FOUND THAT ELT DOES NOT TRANSMIT A SIGNAL EVEN THOUGH RED TRANSMIT LIGHT ON UNIT LIGHTS UP.  UNIT TESTED USING 3 DIFFERENT ANTENNA SOURCES AND VERIFIED THAT ELT BATTERY IS GOOD.  TRANSMIT LIGHT WORKS IN THE ON POSITION AND ARM POSITION WHEN THE G SWITCH IS ACTIVATED BUT STILL NO AUDIBLE SIGNAL HEARD FROM AIRCRAFT RADIOS OR A PORTABLE AM RADIO.
