SCS Pactor-II Modems for SSB E-mail/WXFAX

MarineNet's Wireless high speed SSB E-mail shore stations started with SCS PTC-II modem's and still are! Based on their high quality and great performance under extreme conditions. (Radio Cable Sets Sold Separately)

Key Benefits

• Pactor-III is now the mode of choice for fast reliable E-mail handling of Ham and commercial services. 
• SCS Pactor-II/III modems ability to hear signals in the noise that can't be heard by the ear!
• With the release of the PTC-IIex makes fast radio e-mailing much more affordable without sacrificing speed performance. New IIex now shares added technology to increase stability like the IIPro
• Field proven reliability for years makes SCS the clear industry leader
• SCS-PTC modems are field software programmable/upgradeable. As new features become available (Like Pactor-III software) you just program them in. Your modem won't become yesterday's news anytime soon.

Standard Features of the PTC-IIex and PTC-II Pro

1. VHF/UHF Packet communications capable, built in. No extra modules to buy.
   

2. Up to 30 times faster than AMTOR.
   

3. 32 bit system with Motorola RISC 68360 processor at 25 MHz. 16 bit Motorola DSP 56156 at 60 MHz (30 MIPs).
   

4. Firmware stored in flash memory. Easy update via serial RS-232 link to a PC. Modem tones (mark-space) and shift programmable in 1 Hz steps within all modes.
   

5. Equipped for FAX (AM, FM, Meteosat), SSTV, CW operation with reception and transmission and full compatibility to nearly all modern PC programs.
   

6. Built in mailbox with comprehensive features.
   

7. Common and simultaneous access from all modes (PACTOR-I & II, AMTOR, PACKET).
   

8. Battery backup for the clock and CMOS RAM. No mail loss when switched off.
   

9. Mail display at the front panel shows the operator there is new mail.
   

10. Excellent tuning display with 15 bi-color LEDs with center function. All significant link and controller status are displayed on the eight front panel bi-color LEDs.
    

11. The PTC-IIex is fully usable as a DSP filter for all modes (SSB, CW and others) as a "denoiser" with freely programmable sets of parameters. Features: Auto peak, auto notch, passband filter, inversion, delay line, function generator and more.
    

12. Comprehensive filtering of all inputs and outputs for excellent electromagnetic compatibility.
    

13. Hostmode, extended hostmode, CRC-hostmode. Fully compatible to nearly all modern PC programs. Fully integrates with FBB/Winlink networking and mailing systems.
    

14. Features of the PACTOR-II Mode Automatic frequency tracking allows the same frequency tolerance as with PACTOR-I (+/- 80 Hz). The days of dithering fingers on the dial are over!
    

15. Newly developed on-line data compression system (PMC) reduces the data transfer by nearly 1/2. Fully backwards compatible with all known PACTOR-I implementations, including automatic mode recognition and selection.
    

16. The unit always answers in the mode it has been contacted in (PACTOR-I, PACTOR-II, AMTOR). Utilizing the latest coding technology. Constraint length 9 convolutional coding is used with full frame interleaving and Viterbi decoder combined with very efficient Memory ARQ algorithms.
    

17. Automatic transceiver output power adaptation to the quality of the HF link and the required data throughput.
    

18. Programmable squelch function for RTTY operation.
    

19. CW operation (RX and TX) with automatic speed adaptation using high sophisticated DSP algorithms. Users say: "the best CW receiving computer we have ever seen"
