Produced primarily in the 1970s and 80s, the Narco Escort II became a staple in the experimental and light general aviation communities. While many have since been replaced by modern GPS-integrated units, they remain a notable example of efficient analog avionics engineering.
Narco Escort II is a lightweight, digital "shared system" radio that functions as either a 200-channel VOR/LOC NAV receiver or a 720-channel COMM transceiver. Unlike standard indicators with needle movements, it uses a gas-discharge display for VOR/LOC deviations.
Requires a 1.5 amp circuit breaker between the unit and the aircraft power bus.
: The unit is typically mounted in the instrument panel using a rear support stud for stability. Intercom Configuration narco escort ii installation manual full

Route Pin 5 to the pilot’s control yoke Push-to-Talk button. Pressing this switch grounds the pin, keying the transmitter. Step 3: Antenna Installation Produced primarily in the 1970s and 80s, the
Verify that no wires are pinched or stretched tightly behind the stack. Ground Test Turn on the aircraft master switch and the avionics master.
: Mount the installation sleeve/tray securely to the panel. Use a doubler plate if the panel structure requires reinforcement to avoid excess vibration.
Specific pinouts for connecting to power, antennas, and navigation sources. Unlike standard indicators with needle movements, it uses
: The unit is designed for instrument panel mounting in fixed or rotary-wing aircraft.
: Antennas must be electrically connected to the aircraft ground plane. For composite or thin-skinned aircraft, a doubler plate is required for structural integrity and electrical performance. Intercom and Audio Setup The Escort II includes a built-in 50 mW audio amplifier.
