Barrett 924 fax system

Fax over HF radio

The Barrett 924 Fax system is a simple and reliable hard copy data
transfer system for high frequency radio network requiring minimal
system setup and operator training.

The Barrett 924 HF Fax system is ideal for providing fax connections
between sites that have no connection to telephone systems.

An HF Fax station consists of a Barrett 950 transceiver and 924
modem, a suitable power supply and antenna and an inexpensive
standard fax machine - No computer or expensive software is required.

Operators simply establish a radio link by voice, selcall or ALE, put
the documents to be transmitted to the distant station in the fax
machine and dial in the remote stations number - the system takes
care of the rest. When the Fax has been received by the remote
station an acknowledgment is printed on the local fax just as it
would when using a fax connected to a telephone line.

System setup is simple - enter the HF network frequencies into the
transceiver and enter the stations radio call identification number
through the fax keyboard. The system is ready to send faxes.

Integrated into Barrett Communications standard equipment enclosure,
the 924 Fax modem uses a standard bus cable to connect it to a
Barrett 950 transceiver.

For mobile operation the 924 modem operates with the Barrett 950
remote control transceiver and commonly available 12 volt fax
machines.

The system uses the robust and high speed Clover 2000 protocol to
transmit the fax digitally and error free. With typical good HF
conditions a standard page of text can be sent in less than 3
minutes. Slightly longer than a telephone fax but with no cost.
