This is a brief introduction to the nos-bbs mailing list.
Please save this message for future reference.
The purpose of this list is discussion of the ins and outs of running
KA9Q NOS as something approximating a full-service BBS, which generally
boils down to discussion of the care and feeding of the JNOS version of
NOS, maintained by Johan, WG7J. Discussion of peripheral issues which are
likely to be of interest to NOS BBS sysops, such as the convers server,
NNTP, POP, etc, are also welcome. Many of the list subscribers are active
contributors to the development of the JNOS code. The list is unmoderated,
and is maintained by Barry McLarnon, VE3JF (bm@hydra.carleton.ca).
Submissions to the list go to:
nos-bbs@hydra.carleton.ca
Subscription/deletion requests and other administrivia go to:

The mailing list is also available in daily digest form. To subscribe or

Hi Boys. Two months ago i saw in TV a presentation of two chilean guys
accused to be part of the shining path communications people. Then i
saw two laptops each one with a black box attached to the serial port.
Can this be packet radio systems??
The presentation last only three seconds so i didn't see nothing more.
Do someone know more about it?? I can ask to the latin american discussion
lists for more information if yo want it.
About the DOS Discussion: Here only the rich people or the government can
have 386+ machines (and i am not rich :). We use the nos because it is the
only real choice to have communications for us.
Greetings!!

You might like to talk to Kevin Rowett, Glenn Elmore and Ed Satterthwaite
in more detail about this - although they developed a useful board and even
a good debug setup, they apparently found the ESCC (and, especially I think,
interfacing it to a V40) to be such a headache that I don't think they'll
ever touch Zilog again.
The 68360 looks impressive, but the cheaper (? I suspect) and more easily
available 68302 is probably sufficient, at least for the immediate future.

Subject: Unix-to-Unix beer protocol
NAME
uubp -- Unix-to-Unix beer protocol
SYNOPSIS
uubp [- acefghlqy] site
DESCRIPTION
Uupb allows the user to transfer beer, ale, or other fermented grain
beverages between network sites. Using TCP/IP (telecommunications
protocol for imbibing pilsners), uubp encodes beer from a local
file system into packets suitable for FTP (fermentation transfer
protocol) delivery at a remote IP site.
Example:
% uubp -c"AMBER" -f0.7 -y0 -q2 198.137.240.100
The preceding example sends two six-packs (-q2) of amber ale (-c"AMBER")
with a fizziness quotient of 70%, brewed using yeast of type 0 (saccharo-
myces cerevisiae) to IP address 198.137.240.100, which is the IP address
for the White House.
RESTRICTIONS
Both source and destination sites must be running uubp-daemon. In
addition, local restrictions exist in many areas for the transportation
of alcohol across state lines. The Electronic Frontier Foundation is
currently involved in litigation to ensure the ability to distribute
beer through the uubp protocol according to the 21st Amendment. To
support the SIG of EFF devoted to this cause, join the Homebrewers of
the Electronic Frontier Engaged in Winning Electronic Independence and
Zeroing Establishment Nonsense (HEFEWEIZEN), or send mail to
hefeweizen@eff.eff.org. Be sure to include the entire text of
this manual page.
NOTES
Relax. Don't worry. Have a homebrew!

I think she/he's the only one that has a clue, since the message was
half-baked. Probably a letter would clear things up.

Yes, there are two seperate TX/RX Xtals.

I got mine from Gracilis and told them what freq I wanted. Later I bought
new ones from International. Probably same deal here, or no crystals.

As long as it's in the 440 band, should be no problem. Mine only developed
1.5 Watts, so I think the 2 Watts is max. For tuneup there's one varicap on
each oscillator. I walked my TX on freq with a counter, the RX on freq by
watching the remote station on a scope and centering the discriminator
waveform (the other station was off freq slightly).

Within full quieting range I used about 200 ms, but the link between Noble
and Pauls Valley seems to like 400 ms through an RF Concepts amp. It's
running about S-5, and Pauls Valley is in a hole. These times don't matter
much in the big picture, because AX.25 VC mode adds seconds to minutes to
these delays, and is the real slow down, Rose is used here, rather than IP.

Oof, that's a big bandwidth. First off, my TEKK came with a 20 kHz ceramic
filter (don't know if Gracilis changes those out) but I don't think it'll
pass that??
These radios are pretty neat. They have alot of stuff packed tightly
together, and even more on the bottom side. They didn't simulate any parts
of the radio :-) Someone once reported that they didn't work very well on
a multi-transmitter site (10 or 20 systems on a mountain top probably) but
the radio is enclosed in a metal box. It's worked OK for me, better than my
Alinco which intermods easily and can't be used within 5 miles of downtown
OKC, or any paging tower :-)

Yup, using one here on the local 9600b packet repeater. Last I checked we
were at 33000 pings of 512bytes each, 94% return rate. (we're testing a new link :-)

We just told them what frequencies we wanted and they shipped what we asked for.

Not hard if you have the proper equipment. The alignment instructions I have
call for the use of a spectrum analyzer, communication monitor and DVM. That's
the hard way however, most of us just send them back to TEKK and let them
do it.

I believe there are at least two versions, but don't know what the differences
are. We have had no problems with them, they seem to work well and have not
had any maintanence problems. No amplifiers have been needed, just good 440
beams.

If you get them to work at 19.2 I'd like to know. When I talked to someone
at TEKK about this a year ago they said it wouldn't work. But then again
were HAMs right? Lets try it and see :-)

Just don't expect to put them in a high rf environment, the front ends leave
a lot to be desired.
