HF shortwave radio email
systems offer a low cost alternative to mobile and satellite phone systems and
offers near global coverage.
To use SSB Email you
require an SSB radio such as the ICOM M710 or ICOM M801E or M802, a pactor
modem, a computer running Mircosoft Window and an account with a service
provider like SailMail
and free software
SailMail stations are now using pactor 4, which is twice as fast as pactor 3.
SailCom Marine recommended that anyone considering purchasing a pactor
modem for use with SailMail gives due consideration to the P4dragon DR-7400
All pactor modems supplied from
SailCom Marine include a CD which includes software for email and receiving
weatherfax, RTTY and Navtex weather data broadcasts, plus free 20 page HF email

|SCS P4dragon - PACTOR 4 HF radio
The P4dragon modem can be used for HF SSB email with
SailMail or Winlink and for receiving weatherfax, RTTY and Navtex broadcasts .
The P4dragon supports all pactor modems from PACTOR-1 through to
P4dragon modems allow transmission data via SSB radio and provide
an cost effect alternative to many satellite services.

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
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 dont 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
modul for PTC-IIusb, PTC-IIIusb and P4dragon pactor modems

|SCS Tracker / DSC
TNC has been designed by SCS for custom applications of transferring GPS
positions and other small and reappearing sets of data from e.g. remote sensors
by HF or VHF radio transmission using the new SCS "Robust-Packet" modulation.
Typical applications are weather stations and the tracking of vessels, cars,
trucks, containers and airplanes. The unit receives the GPS data from any
external NMEA device and reports it to the host
Position tracking mode to be
activated by DIP-switch. Transmission of fixed or via NMEA (GPS) given position
in free programmable time intervals in APRS format. Here the Tracker operates
in "sleep mode" and just draws 15 mA of current (@ 13.8 V). Shortly before the
next scheduled transmission it wakes up, switches on the radio, checks the
channel for occupancies (DCD) and transmits the APRS datagram as soon as the
channel is free. Afterwards the radio is switched off again and the Tracker
enters "sleep mode".SCS Data
