Short Description PACTOR II is an advancement of PACTOR I. It is up to 8 times faster than PACTOR I.
I/Q Raw Recording
Audio Sample
PACTOR II is an advancement of PACTOR I. It is up to 8 times faster than PACTOR I.

PACTOR is used by many groups, including Sailmail for mariners to send and receive emails. It is also used by Ham Radio operators, Governmental and Diplomatic agencies, and even NGO's.

PACTOR II has a 450Hz bandwidth. This is a proprietary standard developed by SCS GmbH & Co. KG, Hanau, Germany.

Uses 2 DPSKDifferential Phase-Shift Keying tones. PACTOR I SELCALL is used when establishing an initial connection between two operators.
