HX PRC-6020 — Technical Data Link Report

Summary

4. Data Link Protocols and Networking Stack

The HX PRC 6020 typically implements a KISS-like or PPP encapsulation over its serial data ports, with a native IP stack for Ethernet variants. A typical stack is: radio set hx prc 6020 technical data link

• VHF Data (30-88 MHz): Use a broadband folded dipole (gain 2 dBi). Avoid narrowband whips which cause high BER (Bit Error Rate).
• UHF SATCOM Data (243-270 MHz): Use a helical antenna with pre-amplifier to maintain data lock.
• HF Data Link (2-30 MHz): The AS-2259/GR inverted-V antenna is mandatory for 64 kbps data rates over NVIS.

While the PRC-6020 is primarily a man-pack, it is the core of a larger family of configurations: HX PRC-6020 — Technical Data Link Report Summary 4
