SCS PACTOR Modem Models
This page is preserved as a reference to SCS PACTOR modem models commonly used
with marine and amateur HF radio systems. It includes both PACTOR-4-era equipment
and older PACTOR-II / PACTOR-III modem families that remain in service aboard many vessels.

In a word, the
P4DR-7xxx
modems are f a s t... With a maximum net throughput of 10,500 bps The
P4DR-7800
and DR-7400
P4dragon
modems sport twice the
throughput speed of PTC-IIIusb. The
P4DR-7xxx
modems push data modulation
techniques to the maximum possible while meeting governmental
HF signal bandwidth requirements. Download the

A compact, cost-reduced successor to the original PTC-IIusb modem, the PTC-IIIusb provides the same approximately 5200 bps maximum PACTOR-III net throughput. Designed with cruisers needs in mind, the PTC-IIIusb measures a diminutive 5" wide, 13/4"
high, 51/2"
deep, easily fitting into the limited space at your vessels nav
station. The PTC-IIIusb connects directly to your computer's USB port, provides
computer-controlled frequency selection when used with the
Airmail program, and GPS data can easily be fed into the modem through a
connector on the modem's back panel.

Designed with cruisers needs in mind, the
PTC-IIusb
offers a net throughput of 5200 bps (with an optional P-III
license), connects directly to a computer's USB port, and
gives you computer-controlled frequency selection. GPS data can
be fed into the modem through a connector on the back panel.

The
PTC-IIPro design meets the needs of digitally-oriented
high-tech Amateur Radio Operators. With the ability to add up to
two 2330 Packet DSP modules the PTC-IIPro in effect becomes
three modems in one box; an HF Pactor modem, and two VHF Packet
modems. With at least one 2330 installed and
simultaneously connected to both a HF and VHF transceiver the
PTC-IIPro can be used as a VHF Packet to HF Packet/Pactor
Gateway station. It has a RS-232/serial computer interface
(requires a third-party USB/Serial adaptor), and and provides
computer-controlled frequency selection. |

The
PTC-IIex
provides the same Pactor-II/III performance as the PTC-IIPro and
PTC-IIusb. It has a RS-232/serial computer interface (requires a
third-party USB/Serial adaptor), and is not capable of providing
computer-controlled frequency selection. |

Not pictured in
the line-up are the older PTC, PTC-Plus, PTC-II (predecessor to
the PTC-IIPro), and PTC-IIe (predecessor to the PTC-IIex). |
