Description

I bought this as our spare Pactor modem and stored it during our recent circumnavigation. It was recently (9/17) completely overhauled at Farallon Electronics and is in very good condition. The firmware was upgraded to 4.0 and email/invoice to me stated expect many years of good service. If youre looking at Pactor Modems, dont miss out on this deal! This unit is considered quite robust, and the price represents a significant discount from new. $799.00 + $7.25 S/H
UPGRADED PACTOR III LICENSE. CABLES INCLUDED: serial cable, 9090 interconnect cable, 8083 Fq control cable, large RF chokes.
Fast, full featured and upgradable to PACTOR III. Send email, transfer files, real-time data links. The PTC-IIpro modem from Special Communications Systems is the multimode data interface between your PC and radio equipment. SCS PTC modems use PACTOR II mode, the industry standard, and most robust digital mode available for radio data connections. The PTC-IIpro will maintain links in conditions with signal to noise ratios of minus 18 dB, transferring data with absolutely inaudible signals. The Pro comes standard with 2mb of ram for incoming data storage, integrated RS-232 and TTL interface for control of common radios and a temperature compensated crystal oscillator for stability. The Pro incorporates an audio amplifier for output to a speaker or headphones, which allows the Pros powerful DSP to be used with any audio signal. Built in ability for GPS position reporting. With optional Packet radio modules, the Pro will function as a VHF/UHF modem (up to 19200 baud) and act as a gateway for data between HF and VHF/UHF radios. Easily installed with compatible radios from Icom, Kenwood, Yaesu, SGC, SEA, Furuno, R&S and others. Use the PTC-IIPro with commercial stations worldwide or the international network of Winlink amateur radio operators that support Pactor II. PC software for Windows or DOS. SCS PTC-IIpro Radio Modem HF / VHF / UHF Multiport
Multimode
Terminal Node Standard Features of the PTC-IIpro Hardware Three simultaneously available communication ports: HF and up to two optional VHF/UHF Packet ports. Transceiver control port for remote operation of Icom, Kenwood, Yaesu, Furuno, R&S and SGC equipment. RS-232, TTL and Icom NMEA formats. Highly stable temperature-compensated oscillator. Makes your PACTOR connection even more stable! 2 MB of static RAM. Firmware stored in flash memory. Update via RS-232 to a PC. 32 bit system with Motorola RISC 68360 processor, 24 bit Motorola DSP 56303 at 100 MHz (100 MIPS). Built-in audio amplifier. Connect your favorite speaker and use the PTC-IIpro as audio denoiser. The volume is controlled by software! The PTC-IIpro is fully usable as a DSP filter for all modes with freely programmable sets of parameters (auto peak, auto notch, passband filter, inversion, delay line, function generator and more). Equipped for PSK31, FAX (AM, FM, Meteosat), SSTV, CW operation with reception and transmission. Modem tones (mark-space) and shift programmable in 1 Hz steps within all modes. Built in ability for automatic GPS position reporting. Built in mailbox with comprehensive features. Common and simultaneous access from all modes (PACTOR I, II, III, AMTOR, PACKET). Mail display at the front panel shows the operator there is new mail. Battery backup for the clock and CMOS RAM. No mail loss when switched off. Software controlled power off function. The new OFF command turns the unit off. Any character sent to the PTC-IIpro over the serial interface will switch it on again. All significant link and controller status are displayed on 15 bi-color LEDs with center function and 10 character dot matrix display on front panel. 10 character display for mode, parameters such as call sign of a connecting station, channel-busy detection and much more. Comprehensive filtering of all inputs and outputs for excellent electromagnetic compatibility. HF VHF/UHF gateway and cross band digipeating with comprehensive and automated link establishment features from remote. PACTOR goes PACKET. Hostmode, extended hostmode, CRC-hostmode. Compatible with most modern PC programs. Integrates with FBB/Winlink networking and mailing systems. Features of the PACTOR II Mode Automatic frequency tracking allows the same frequency tolerance as with PACTOR I (+/- 80 Hz). Newly developed on-line data compression system (PMC) reduces the data transfered by nearly 1/2. Fully backwards compatible with all known PACTOR I implementations, including automatic mode recognition and selection. The unit always answers in the mode it has been contacted in (PACTOR I, PACTOR II, AMTOR). Constraint length 9 convolutional coding is used with full frame interleaving and Viterbi decoder combined with very efficient Memory ARQ algorithms. Automatic transceiver output power adaptation to the quality of the HF link and the required data throughput. CW operation (RX and TX) with automatic speed adaptation using highly sophisticated DSP algorithms. Available Options
