Weather fax (RADIO FAX) charts can be received without PACTOR, but simpler/less expensive software
(in some cases just a PC) is needed. The USCG broadcasts NOAA forecast
products multiple times daily.
For more info on Radio
Fax products see http://weather.noaa.gov/fax/marine.shtml
There are a number of applications available to receive Radio
Fax. I use Xaxero which uses an external demodulator to process the Radio FAX signal. These software/hardware configurations are limited in functionality just to receive Radio Fax so they are simpler/less expensive than PACTOR.
There is even a simple Android App now that seems to work pretty well, but I haven't tested it a lot yet.
PACTOR is a full function RF/DIGITAL modulator/demodulator (MODEM). It can be used to send/receive any type of data. Generalization and transmit capability make it more complex and thus more expensive.
