PACTOR - Wikipedia
PACTOR is a radio modulation mode used by amateur radio operators, marine radio stations, military or government users such as the United States Department of Homeland Security, and radio stations in isolated areas to send and receive digital information via radio. [citation needed]
PACTOR NEWS
PACTOR, of the other hand, marries recovery of weak signals combined with faster recovery rates based on propagation conditions. PACTOR also uses concurrent data streams (like QPSK) over a similar bandwidth, but also employs a variety of compression techniques.
PACTOR - ARRL
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.
PACTOR-4
PACTOR-4, with its 10 speed levels and adaptive equalizer, adjusts itself ideally to varying channel conditions, and guarantees reliable data transfer even under very poor propagation conditions.

Nov 25, 2021 · PACTOR-I is a digital data protocol combining elements of PACKET and AMTOR ARQ Automatic Repeat reQuest Automatic Repeat Query. PACTOR-I is used by many groups, including Sailmail for mariners to send and receive emails.
WB8NUT - Digital Modes Information Page
PACTOR is an FSK mode and is a standard on modern Multi-Mode TNCs. It is designed with a combination of packet and Amtor Techniques. Although this mode is also fading in use, it is the most popular ARQ digital mode on amateur HF today and primarily used by amateurs for sending and receiving email over the radio.
With the introduction of the P4dragon DR7800 modem, SCS also announces PACTOR-4 as a new mode of high performance data transmission over HF frequencies. P4dragon stands for high sophisticated algorithms of communication engineering and high computation power of the PACTOR modems of the fourth generation.

PACTOR III - ARRL
PACTOR-III is a software upgrade for existing PACTOR-II modems that provides a new data transmission mode for improved speed and robustness. PACTOR-III is not a new modem or hardware device. Most current PACTOR-II modems are upgradeable to use PACTOR-III via a software update since PACTOR-II firmware accommodates the new PACTOR-III software.
