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 tones spaced 15.625 Hz apart, in the 1 kHz bandwidth.
- 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
