Software such as JVcomm will probably do the job for you. You can get a
demo version of the software from http://www.jvcomm.de/indexe.html
The software utilizes the soundcard to receive fax transmissions. The demo
version will imprint "demo" on the received faxes, but other than that
works well.

I had problems with JVcomm stair-stepping the faxes and could never get it
resolved. I now use the SailMail companion program GetFax, but that
requires a Pactor HF modem which is probably overkill for you at $800.

So I have a laptop and a receiver (Yaesu) that covers the frequencies
from 2 Mhz to 30 Mhz. What kind of black box and software do I need to
display weather fax maps on my laptop screen ?

I want to use that on my 26' trailerable boat during a cruise, it will
not be a permanent installation.

Thanks in advance,
