digital communications network by working at the grass-roots level. The
tools are there, all we have to do is start building...
Here is a How-To:
http://www.gbonline.com/~multiplx/wireless/
A modern hi-speed digital station is much cheaper than an old TNC-based
packet station used to cost!
HF and CW are lame. The vast majority of technically-savvy young people
could care less about them. We have to move past the CW debates and start
implementing a digital network. Most digital RF experimentation is now
being done by non-hams. Since we have less restrictions than the Part 15
devices, we should be able to get some of the bright, young people to take
interest in the hobby - but NOT if we continue to over-emphasize HF and CW.

Again, I am unfamiliar with foreign laws, but in the USA a patent
does not prohibit an individual from copying a design for his/her
own personal use. All it does is prohibit someone from commercializing
on the design, surely something no amateur radio operator would be
guilty of. 73, Cecil

Correct - you're incorrect. (:-)
Example: DES [encryption] protocol is public, free and
extensively documented - but forbidden to use. PACTOR-II
is not that well-documented, yet permitted.

My poor eyesight is responsible for that. That 'K' looked

Sure you can, and use it too. Even make one for a friend to use so you
can work one another.
Just don't start manufacturing and selling them in countries where patent
protection exists.

Rob:
In the USA a patent does not forbid you from building an implementation of
the patent for your own personal use, in fact that is specifically allowed
under patent law.
In theory the patent "teaching" is supposed to give you enough information
to be able to do just that. If there is not sufficient information for you
to build a working model and this can be proved then the patent is invalid!
If you could show to a court with appropriate jurisdiction, and to it's
satisfaction, that there is not enough information in s patent for a person
skilled in the art to construct a working model then the patent may be
declared invalid.
The point is patents are supposed to "teach" and reveal all necessary
information to construct a working model!
What you are forbidden to do under patent law is to make a business out of
it by building patented inventions and selling them to others without the
specific permission of the patent holder/assignee.

The difference is that DES is intended to obscure the content of the
transmission and you have to have the key to decode it. Pactor-II is
not intended to obscure the content and no key is needed to decode it.
That's the whole point of the regulation - to prevent the use of any
technique to encrypt or obscure the content of the transmission. The
regulation is *not* intended to prevent the use of protocols to
enhance the transmission or to make sure that only "open"
non-patentend protocols are used.
