Just doing my first annual and did the ELT test this afternoon. I have the ACK406 E-04. Did the normal test/reset and got the correct beep as it reset.
Then I removed it from the a/c and did the shake test to trigger the G switch.
That also worked fine, so I reinstalled it in the aircraft and pushed the test/reset button one more time. This time I got three beeps which indicates low RF output. I don't know what this means exactly, but take it to mean weak signal to the antenna.
Tried the coax connections to the antenna and they seem fine.
Anyone got any ideas? I'll phone ACK tomorrow, but hoping to get a jump on it.
This a one year old unit, never been fired in anger.
