Bernard:
Yes, this is very nice indeed! I'm still in the learning stages of
higher speed wireless systems, so the more information I have, the
easier it will be for me to learn and put something together. The hard
part is finding someone close to me that is willing to put something
like this together and start building the network. I think maybe though
I may be putting the cart before the horse. As I have been reading about
all this, it seems to me, hams need a faster way to transmit information
across slightly longer distances - say 500 miles or so. The short hop,
very highspeed stuff looks like it already has several ways of
accomplishing these goals. If the backbone links have a common, open
source protocol that can be implemented easily, using common HF
equipment, then should we care how the local very highspeed LANs are put
together?? Essentially, if two hams use one approach on 1.2 GHz, and
another pair on 10 GHz with atleast two people running the common HF
protocol, wouldn't this also work just fine?? If PACTORII can be
duplicated within GNU licensing, or something else is developed, it
wouldn't take much to build a small, dedicated HF transceiver to handle
the RF side. Plenty of plans for 10 watt QRP rigs, freely available that
wouldn't cost too much or be too difficult to build. Just thinking
outloud here!
