technical specifications, digital communications mode that conveys 8-bit digital data over
narrow-band high-frequency radio.
-2000 is a faster version of CLOVER
(about four times faster) that uses eight tone
pulses, each of which is 250 Hz wide, spaced at 250-Hz centers, contained within a 2 kHz bandwidth between 500 and 2,500 Hz
- Domino is the name given by the developers to a family of IFK coded coherent phase single tone
MFSK keyed modes, using sequential tone
-pairs in two alternate fields arranged as orthogonal but interleaved tone
- G-TOR is a trademark of Kantronics, Inc. G-TOR (Golay-Teleprinting Over
Radio) can be viewed, in part, as a variant of the Automatic Link Establishment (ALE) protocol, outlined in MIL-STD-188-141A.
Mt-63 technical description
- The MT-63 modem, constructed around a high speed DSP processor, either in a dedicated external DSP unit like the Motorola EVM, or in PC software using the PC sound card, transmits 64 tone
s spaced 15.625 Hz apart, in the 1 kHz bandwidth.
- PACTOR can be viewed as a combination of two earlier digital modes, packet radio and AMateur Teleprinting Over
Radio (AMTOR). PACTOR provides improved throughput because its transmission speed adapts to the quality of the link and it uses Huffman compressed characters.
