G-TOR Mode
G-TOR is a completely new hybrid - ARQ HF digital communications system for
commercial and amateur services. Golay error correction coding forms the basis
for G-TOR (short for Golay-TOR). G-TOR is an innovation of Kantronics, intro
-
duced in 1994, first in the KAM Plus.
The benefits of G-TOR are exceptional, compared the previous multi-mode HF
digital modes: 1) substantially higher effective data rates (throughput); 2) appar

ent reduction in the effects of interference and multi-path; and 3) a low cost for
error-correcting systems.
The key features of G-TOR are atypical: 1) extended Golay forward error correc

tion coding; 2) full-frame interleaving; 3) on-demand Huffman and run-length
encoding; 4) link-quality-based baud rate: 300, 200, 100; 5) 2.4 second hy

brid-ARQ cycle; 6) reduced data frame overhead; and 7) use of standard AFSK
tone pairs (mark and space).
