The keyword “installation manual full” is crucial. An "Owner’s Manual" is not enough—it only covers basic operation. A full installation manual (Narco Part Number typically 861000-xxxx, depending on revision) includes:
If "Narco Escort II" refers to a specific piece of software, hardware, or a device used in a particular industry (like agriculture, navigation, etc.), it would be best to consult the official manual or contact the manufacturer directly for the most accurate and detailed instructions.
Narco Escort II is a specialized, lightweight "shared system" avionics radio designed for light aircraft. Unlike standard dual-function units, it can operate as either a NAV receiver or a COMM transceiver, but not simultaneously. System Specifications Approximately 3 pounds. COMM Capability: 720-channel transceiver. NAV Capability: 200-channel VOR/LOC receiver.
Uses a gas discharge display for frequencies and a row of lights (instead of mechanical needles) to show VOR/LOC deviations. Operational Characteristics
The unit is unique because it shares internal circuitry between navigation and communication functions. Users must toggle between modes; it cannot receive a VOR signal while the pilot is transmitting or receiving on a COM frequency. This design was intended to save weight and space in cockpits where panel real estate was limited. Key Features Frequency Storage:
Includes the ability to preset frequencies for quicker transitions between ATC sectors. Solid-State Design: narco escort ii installation manual full
Replaced older tube-based technology, offering better reliability in the high-vibration environment of a small airplane. Integrated Indicator:
Unlike many radios of its era that required a separate external head to show navigation data, the Escort II built the VOR/LOC indicator directly into the face of the radio using LED-style lighting. Historical Context
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 While many have since been replaced by modern GPS-integrated units, they remain a notable example of efficient analog avionics engineering.
For those looking to maintain or install such equipment, consulting with a certified avionics technician or an FAA-certified repair station is necessary to ensure compliance with aviation safety regulations and to verify that the specific airframe can support the electrical load and antenna requirements.

The Narco Escort II is a legacy self-contained Nav/Com radio unit featuring a gas discharge display for frequencies and a row of lights for VOR/LOC "needle" deflection. This report summarizes the essential installation data found in available technical documentation. 1. System Overview Mounting: Designed for instrument panel mounting. Voltage: Operates on 14/28 V systems. The keyword “installation manual full” is crucial
Critical Note: For 14V aircraft, you must jumper pins 8 and 10 on the P301 connector.
Display Type: Gas discharge for frequencies and LED-style indicators for VOR/LOC deviations, replacing traditional mechanical meter movements. 2. Electrical Pinout (P301 Connector)
The P301 is a 15-pin connector. Looking at the rack from the back, pins are numbered 1–15 from left to right. Wiring Detail 1 & 2 Power Input 14/28V DC input 3 Airframe Ground Connection to aircraft skin 5 Low Level Audio 330 ohm impedance; used for audio summing networks 6 Headphones Audio

Nav Antenna: V-shaped dipole (e.g., flat copper strips) typically built into the airframe or canard for specialized aircraft. Cabling: Use RG-58 A/U coax for connections. 4. Operational Functions
Intercom: The unit includes a built-in intercom function activated by grounding Pin 12. Both microphones must be the same manufacturer and model for proper balance.
Ident: PULL the volume control to activate the IDENT circuit for station identification.
Frequency Transfer: Use the "FLIP" momentary switch to exchange Active and Standby frequencies.
