The PTC-IInet is a clever combination of a PACTOR modem and an embedded Linux-computer. With this, it represents a complete base-station with Internet-Gateway for a PACTOR-IP-Bridge network. Just connect the PTC-IInet to an existing router and configure it using its web-interface.

The Modem Part

• One single connector to the HF/VHF transceiver for all modes.
• Transceiver control for ICOM, YAESU, SGC, KENWOOD and Rohde&Schwarz, including RS232 for modern transceivers.
• Packet-Radio with 300, R600, 1200, 9600 and 19200 baud with built-in DSP.
• With two high performance processors from Freescale, the PTC-IInet achieves outstanding flexibility.
• Sophisticated signal processing and analyzing, maintains a stable HF link even during difficult propagation conditions.
• Temperature compensated crystal oscillator.
• Tuning bar display with 15 dual color LED lamps.
• 2 MB of static RAM.
• Electronic (silicon) serial number.
• Noise free HF reception by use of HF suitable construction, 6 layer multilayer board and filtering of all inputs and outputs.
• Compact SMD assembly.
• Flash-ROM for easy firmware updates.
• Dimensions: 172 W x 43 H x 205 D mm, 1.69 H x 6.77 W x 8.07 D inches.
• Weight: 740 g.
• Power Supply: +10 to +20 V DC, 300 mA max. Reverse polarity protected. Fuse selfresetting.

The Linux Part

• Embedded Linux module DNP/5282.
• 64 MHz ColdFire prozessor MCF5282.
• 16 MB RAM, 8 MB Flash.
• 10/100 MBit Ethernet.
• µClinux with Kernel 2.4.27.
• Comfortable web-interface for configuration and control.
• Update of µClinux, web-interface and the modem firmware easily over the Internet.
• Complete (Linux) source available!

PACTOR-II

• Max. 1200 Bit/s, incl. data compression.
• Automatic adaption to the channel quality in 4 speed levels.
• Bandwidth 500 Hz.
• Use of the most modern transfer mode technics: convolutional coding, Viterbi-decoder, soft-decision and  Memory ARQ allows error free data transfers even with inaudible signals.
• Automatic frequency correction of ± 80 Hz.
• Automatic adaption of the radio’s transmit power to the channel quality is possible.

PACTOR-III*

Like PACTOR-II, but:

• max. 5200 Bit/s, incl. data compression.
• Automatic adaption to the channel quality in 6 speed levels.
• Bandwidth 2400 Hz.

Includes installation manual, CD-ROM, cables and power plug.

Profile of a PACTOR user:

Also the German coast-station KielRadio uses the PACTOR IP-Bridge (PIB) to provide reliable and inexpensive data communication for commercial maritime applications. The principle is now easily available to everybody with using the PTC-IInet. Together with other coast stations KielRadio is member of the "Global-Link-Network" (GLN), which operates PIB and PACTOR-III.
