Avionics

ELT installation  ( 3 hrs )

Started installation of ELT per Sect 53-02 ( ACK Tech  Model E-04 121.5/406 Mhz Emergency Locator Transmitter).  A lot of material to preview in ACK's Installation/Operator Manual.   Installed Antenna in baggage area per Steps 1-6, mounted tray in Aft Fuselage, drilled 4 holes in bottom of Vert Stabilizer to mount Audio Alert Indicator.  Soldered 4 wires to DIN connector per Steps 1-6 at Sect 53-04 which was kinda challenging due to small size (and triple checking to get order correct!).  Need special Duracell Lithium batteries for Audio Indicator (CR2  3V) and Cockpit Remote (PX28L  6 V) before I can mount ELT, etc.
Kit doesn't include all required hardware that Sect 53 shows

Antenna is bent to conform to Rear Window shape

Note tray for ELT in background.
