Overview
The Heathkit Model HO-13 Ham-Scan Panoramic Adapter is designed for use with amateur and general coverage receivers. It provides a visual display of signal amplitude versus frequency, with a continuously variable frequency width of approximately 30 kc to 100 kc, centered on the receiver’s intermediate frequency. The device allows users to visually monitor the portion of the band centered on the receiver’s tuned frequency, identify transmission types (SSB, AM, CW), and check for out-of-band operation, among other functions. The manual covers specifications, assembly, operation, troubleshooting, and service information.
