I'm new to HF communication. I would like to know what are the possibility of TCP/IP over HF using a software PACTOR compatible modem? Is there any software HF modem that allows TCP/IP over HF (20-30 MHz range)?
HF Data solutions provided by manufacturer like http://www.codan.com.au
seems to be very expensive (US$ 6000/- for a set of HF Modem and Transceiver).
Solutions listed at http://www.nsrc.org/wireless/HF-radio.html
seems to be quite interesting, but they are costly for me to afford.
Eagery waiting for a solution!
