Got home from Petit Jean RV Fly-In yesterday around noon. Had to spend the night 1.5-hours away because of weather. Airplane spent three nights on the ramp at KPMJ but spent the night in a hangar at 18A.
With two Apollo comm radios in the airplane, I always monitor 121.5 while flying on Comm 2. Because my hangar door has a remote control, I typically open the door as I taxi toward the hangar stopping before I reach the door.
Monday, as soon as the engine shut off, (radio was off when I pulled the mixture, killed the ignition, and turned off the master) I heard a beeping sound. For the first time since July 2019 installation, my ELT was going off. Had to press and hold the RESET button and it finally quit making noise and the RED led was no longer flashing.
I phoned the NOAA number just to make sure that search and rescue knew I was ok. They have not gotten the signal yet but took down my info to know that if it comes in it is a false alarm.
I remember that others have had ACK E-04 False Alarms so did a search and this is the first thread that I found.
Hope this is my last false alarm. I know it was not my smoothest landing but the G-meter says that it was not a hard landing.
I see another thread about ELT false alarms and will read that also. IIRC, it was a different manufacturer's ELT.
