OpenTNC Cable

This high-quality, standalone radio interface cable connects your TNC to your transceiver. Featuring a standard DB9 connector on the TNC side, these cables are wired to match the classic Kantronics pinout. They serve as a direct replacement or expansion cable for the OpenTNC, as well as a cost-effective, high-reliability alternative for Kantronics and other compatible TNCs. Available Variants Mini-DIN 6: Connects to the data port of most modern mobile transceivers. Kenwood K1: Connects to standard handheld transceivers (HTs) utilizing the common 2-pin K1 configuration. Technical Specifications Length: 60 cm Jacket Material: Flexible, durable Thermoplastic Elastomer (TPE) Shielding: Dual-shielded (foil and braided shield) explicitly engineered to mitigate RF ingress and prevent common mode noise from degrading data packet transmission. TNC Interface: DB9 male (OpenTNC pinout, Kantronics-compatible) Ensure your specific TNC equipment shares the Kantronics DB9 wiring standard before using this cable with non-NA6D hardware.
