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
called AirMail3. Most
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
user guide.

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. |

The “Tracker/DSP
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
station.
APRS-Tracking-Mode
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
