Ok, so let's made all home-made and don't let people
buy ready transceivers like Kenwood, Icom etc. There
is like CB in your meaning. What about all these hams
buying ready transceivers and components like PA's,
baycom modems and more? Are they CB entusiasts ?
No! So if I can buy new HF radio in my store,
why can not highspeed packet radio link? Are there
any differenties? :)

And what to do with measurement equipment, if there no
publically published PCBs files of for example WBFM 70cm
radio? What to do with JPG's I found on Hardware Info Desk
WWW page ? Poor quality, poor resolution... I can made
a radio (even without knowlegde of electronics) if I have
PCB images for Atrax, OrCAD or other software for developing
PCBs and shemes.

Ok, if there is very difficult to make a kit, then it would
be good to publish more complex descriptions about how to
mount the radio, list of elements (no, on the www there is
no list of elements of any projects - only JPG's exists,
but a lot of elements descriptions are unreadable due to
poor resolution of JPG file.). And at the end, description
of tuning should be placed on the www. All the Hardware Info
Desk pages are for engineers, specialists, not for common
amateurs. So my conclusion is (and this is to S5 highspeed
packet authors): publish PCB files with description for
holes, full list of elements and description how to tune
the radio up to work. Even the best project is not usable,
if people can't easily reproduce it. Dot. :)

Listen: I can produce 1k2, 2k4 and 9k6 radio modems and
I know about how to connect it all together because it
is very well documented. There are tons of publications
for this kind of modems or radios. 2m,70cm of course.
Here in Poland, speed of 38400 is currently in people's
dreams, they don't know how to "touch" this. With more
complex instructions highspeed packet radio probably
faster come to Poland and other near countries :)
P.S. Of course always if I write long english text, I
want to sorry for my terrible bad english :)
