Product Information

The Pactor PR-7800 "Dragon" is recommended for radio data enthusiasts wishing to establish their own land based data receiving station. The Dragon operates at the fastest pactor 4 data speeds but has added functionality including the ability to network with a chain of pactor modems.

QUICK SUMMARY
The P4dragon modem can be used for HF SSB email with SailMail or Winlink and for receiving weatherfax broadcasts.
The P4dragon supports all pactor protocols from PACTOR-1 through to PACTOR-4.
PACTOR-4 offers data speeds over twice the speed of PACTOR 3.

P4dragon modems allow transmission data via SSB radio and provide a cost effect alternative to many satellite services.

Highlights of PACTOR-4:

Our brand-new HF modem P4 Dragon DR7800 is the uncompromising advancement in the SCS line of pactor modem technology. The P4 Dragon is designed for marine, ham, military or commercial email applications using HF radio as the transmission medium. The DR-7800 modem is software-compatible with existing software, such as AirMail, RMS Express, Alpha, etc. Due to the pin compatibility of the radio equipment ports a change-over from the well-tried pactor 2 / 3 technology to the innovative P4dragon technology is made convenient: re-plug, switch on and enjoy the higher speed and robustness of  Pactor 4 connectivity. 

The elegant design and the excellently readable and informative OLED display including the simple upgrade facility (updates free of charge!) round off the concept of the absolutely latest shortwave modem from the house of SCS.

Using AirMail Freeware for Windows XP/Vista/Windows 7.

We recommend utilisation of Icom branded HF SSB radio models that have remote frequency control (this all modern Icoms such as the M700, M710, M802, M801e, Icom 78, Icom 718, Icom 706mk2g etc).

Price does not include the optional bluetooth module (refer options below if you wish to add this module)

This system allows AirMail 3 to control both the modem & radio frequency selection using a single USB Port or BLUETOOTH (optional) on the associated computer.

Each System is includes AirMail-3 for SailMail and Winlink, GetFax, Viewfax and ViewGrib on CD. The package also includes the following:

1 Dragon DM-7800 Pactor 4 USB Modem

1 PTC/TRX 1.5m cable, Audio to (for Icom model radios only)

1 PTC/Freq 1.5m cable, Freq. to (for Icom model radios only)

1 set of Ferrites - set 6 clip-on cable ferrite filters

1 set-up and operations manual on CD

1 standard 1.5M long USB cable

1 68-page Sailors' Quick-Start Guide to SailMail / Airmail / Winlink 2000

* IC-M802 / M801e installations and other “remotehead” radios may require longer than 1.5m cables – See Options below - we do not recommend utilising cables longer than 1.5 metres.

Note: Annual SailMail Membership is payable to the USA at a current cost of US$250 at the applicable rate of the day. This membership due is not included in our package price and must be paid separately.  You can apply for Sailmail membership via the web at this link: http://www.sailmail.com/FormAppl.htm

The current Airmail software, USB modem and USB cable offered, all work well under Windows XP, Vista and Windows 7. Although operation with other older windows operating systems (ie Win 98, 2000 etc) is possible, performance can be erratic and no technical support is provided. Airmail also runs on MAC systems running Windows with Boot Camp, Parallels, or similar programs (we do not provide support for Apple Mac systems).

Although a CD with detailed help files is provided with each modem purchase, sometimes you just cannot beat the convenience of having a physical reference booklet sitting by your pactor modem installation (to look up those not so often used features of the Airmail software).  The 68-page Sailors' Quick-Start Guide to SailMail / Airmail / Winlink 2000 is chock-full of detailed step-by-step instructions, diagrams, and more than 70 screen shots to quickly get you sending e-mail and receiving Weather FAX. This booklet is included with your modem purchase

If you require cabling longer than 1.5 metres or if you are using a non Icom branded radio we can make up custom cables for you - the usual cost for this service is $85. Conditions apply. Please email us for details.

If you require additional clip on fairites (note 6 are already included with your package) then these can be purchased at additional cost under options below.

THE PACTOR MODEM PACKAGE CANNOT BE PURCHASED THROUGH THE SHOPPING CART AS WE NEED SPECIFIC TECHNICAL INFORMATION IN RESPECT TO YOUR HF RADIO INSTALLATION TO COMPLETE YOUR ORDER. PLEASE CONTACT US BY PHONE AT             07-41257700       TO PLACE YOUR ORDER

 



Why have a Bluetooth modem!
The data stream signal of a USB interface is located in the middle of the shortwave bands. Therefore, the USB data signal cannot be separated from the shortwave signal being transmitted or received by simply filtering.

Mutual interference is possible, especially where the antenna is located close to the modem/PC setup (ship borne installations). Mutual interference in this case means that the transmitted HF-signal can disturb the USB data stream between PC and modem, as well the USB data stream can disturb the radio reception of shortwaves.

Bluetooth can help solve this problem, as Bluetooth and shortwave radio signals don’t interfere with one another. Additionally, eliminating the USB cable connection, the danger of ground loops and parasitic currents distorting the radios signal modulation are removed, which will lead to a better transmission quality.
