The is a legacy general aviation navigation system that was a staple in many private aircraft during the 1970s and 80s. Known for its compact design—combining a VOR/LOC indicator with the navigation receiver itself—it was a popular choice for Cessna, Piper, and Beechcraft owners looking for a self-contained nav solution.
Solution: Test the Antenna Voltage Standing Wave Ratio (VSWR) using a specialized meter. The VSWR should be less than 2.0:1. High VSWR usually points to a poorly crimped BNC connector or a corroded antenna base connection to the fuselage skin.
Ensure the location is free from excessive vibration and allows for adequate cooling. narco escort ii installation manual full
The manual mandates a functional check following installation:
The base of each antenna must make metal-to-metal contact with the aircraft skin. Remove all paint, anodized coatings, and primers around the mounting holes. Install an internal doubler plate to ensure long-term structural integrity and a solid RF ground plane. 4. Pre-Flight Post-Installation Checks The is a legacy general aviation navigation system
Critical Note: For , you must jumper pins 8 and 10 on the P301 connector.

Ensure a high-quality ground connection. Poor grounding is the #1 cause of radio noise. Audio and Mic: Microphone Audio: Pin 7. Key Line: Pin 11. Audio Output (Phone): Pin 5 & 6.
Before starting the installation process, make sure you have:
A 5-amp circuit breaker is standard for this installation.
Correct wire gauge selection and termination are vital to prevent radio frequency interference (RFI) and power dropouts. Wiring Specifications : Use minimum 16 AWG stranded aviation wire .
