The is a legacy, self-contained aviation NAV/COMM radio system designed to provide general aviation aircraft with essential VHF communications and VOR/LOC navigation capability within a single instrument panel footprint. Unlike traditional stack avionics that split the receiver from the cockpit display, the Escort II integrates its receiver, tuning knobs, and a specialized gas discharge digital display (which replaces mechanical CDI needles with a solid-state light-bar deviation indicator) into one consolidated unit.
Externally grounded via a switch to bypass transmitter modulator Mic/Phones Ground Dedicated ground for audio circuits 14 Key line for the transmitter 3. Antenna Requirements Com Antenna: Standard 50 Ohm impedance.
The process of mounting the radio typically involves the following steps:
Standard VOR/LOC horizontal dipole or V-blade antenna. Cable: RG-58A/U 50-ohm coaxial cable.
Turn off the master switch and insert the radio fully into the tray, tightening the front-panel locking screw clockwise until secure. COM Transceiver Test narco escort ii installation manual full
Ensure that your antenna mounting brackets are completely stripped of paint where they contact the skin of the airplane. This establishes a clean RF ground plane. High voltage standing wave ratios (VSWR) caused by bad ground shielding can permanently damage the radio's transmitter stage. Advanced Intercom Configurations
Once installed, power on the unit and verify the gas discharge display is functional. narco avionics escort ii - AeroElectric
The Escort II requires a standard 3-inch instrument hole. It should be mounted within the pilot's primary field of view, free from excessive vibration. B. Wiring and Connections
: An Intercom Key function is available via Pin 12. When this pin is externally grounded through a switch, the microphone audio bypasses the transmitter and is amplified for cabin use. 5. System Calibration and Testing The is a legacy, self-contained aviation NAV/COMM radio

Because Narco Avionics is no longer in business, sourcing a complete Narco Escort II installation manual can be challenging. The sections below outline the full technical requirements, pinout diagrams, mounting procedures, and post-installation steps necessary to properly install and ground this classic avionics unit. 1. Mechanical Mounting & Panel Cutout
The rear interface of the unit utilizes the multi-pin . Wiring must be completed using high-quality 18 AWG and 20 AWG stranded copper wire. Pin Number Wire Size (AWG) Designated Function Installation Connection Notes Pin 1 14V/28V Power Input Direct line from avionics master bus circuit breaker. Pin 2 14V/28V Power Input Dual power line; parallel tie to Pin 1. Pin 3 Airframe Ground Heavy gauge link to the central ground point. Pin 4 Airframe Ground Dual ground line; parallel tie to Pin 3. Pin 5 Low-Level Audio Bypassed routing for auxiliary audio mixing. Pin 6 Headphones Audio High-level output rated at 50 mW across 300 ohms. Pin 7 Leave completely blank. Pin 8 Transmitter A+ Linked internally; requires a jumper for 14V use. Pin 9 Transmitter Key Connects directly to the Microphone jack tip contactor. Pin 10 Switched A+ Jumper to Pin 8 specifically for 14V configurations. Pin 11 Microphone Audio Carries voice audio to the internal modulator. Pin 12 Intercom Key
