subject: Introduction to Blacknet
Introduction to BlackNet
Your name has come to our attention. We have reason to believe you may be
interested in the products and services our new organization, BlackNet, has
to offer.
BlackNet is in the business of buying, selling, trading, and otherwise
dealing with *information* in all its many forms.
We buy and sell information using public key cryptosystems with essentially
perfect security for our customers. Unless you tell us who you are (please
don't!) or inadvertently reveal information which provides clues, we have
no way of identifying you, nor you us.
Our location in physical space is unimportant. Our location in cyberspace
is all that matters. Our primary address is the PGP key location:
"BlackNet<nowhere@cyberspace.nil>" and we can be contacted (preferably
through a chain of anonymous remailers) by encrypting a message to our
public key (contained below) and depositing this message in one of the
several locations in cyberspace we monitor. Currently, we monitor the
following location: the "Cypherpunks" mailing list (cypherpunks@toad.com).
BlackNet is nominally nondideological, but considers nation-states, export
laws, patent laws, national security considerations and the like to be
relics of the pre-cyberspace era. Export and patent laws are often used to
explicity project national power and imperialist, colonialist state
fascism. BlackNet believes it is solely the responsibility of a secret
holder to keep that secret--not the responsibilty of the State, or of us,
or of anyone else who may come into possession of that secret. If a
secret's worth having, it's worth protecting.
BlackNet is currently building its information inventory. We are interested
in information in the following areas, though any other juicy stuff is
always welcome. "If you think it's valuable, offer it to us first."
- trade secrets, processes, production methods (esp. in semiconductors)
- nanotechnology and related techniques (esp. the Merkle sleeve bearing)
- chemical manufacturing and rational drug design (esp. fullerines and
protein folding)
- new product plans, from children's toys to cruise missiles (anything on
"3DO"?)
- business intelligence, mergers, buyouts, rumors
BlackNet can make anonymous deposits to the bank account of your choice,
where local banking laws permit, can mail cash directly (you assume the
risk of theft or seizure), or can credit you in "CryptoCredits," the
internal currency of BlackNet (which you then might use to buy _other_
information and have it encrypted to your special public key and posted in
public place).
If you are interested, do NOT attempt to contact us directly (you'll be
wasting your time), and do NOT post anything that contains your name, your
e-mail address, etc. Rather, compose your message, encrypt it with the
public key of BlackNet (included below), and use an anonymous remailer
chain of one or more links to post this encrypted, anonymized message in
one of the locations listed (more will be added later). Be sure to describe
what you are selling, what value you think it has, your payment terms, and,
of course, a special public key (NOT the one you use in your ordinary
business, of course!) that we can use to get back in touch with you. Then
watch the same public spaces for a reply.
(With these remailers, local PGP encryption within the remailers, the use
of special public keys, and the public postings of the encrypted messages,
a secure, two-way, untraceable, and fully anonymous channel has been opened
between the customer and BlackNet. This is the key to BlackNet.)
A more complete tutorial on using BlackNet will soon appear, in plaintext
form, in certain locations in cyberspace.
Join us in this revolutionary--and profitable--venture.

Signal of Meteor 2-21 seems to become a bit stronger,
but remains weak compared to the other APT-Satellites.
Meteor 3-3, -4, -5 and -6 were inactive. The illumination-
conditions over the northern hemisphere slowly become
better, increasing the vis-contrast (exspecially for
NOAA-9). NOAA-11 drifted to late afternoon, passing
northbound roughly one hour west of the terminator at
50 deg NLat, the right parts of vis-images are quite dim.

Subject: Cable Before the PreAmp
To: ham-space@ucsd.edu
The system I am currently using has two omni directional antennas for 2
meters and 70 cm. The 70 cm antenna is the M Square egg beater and it is
up about 20 feet - connected to the rig with Beldin 9913 via N connectors.
I do okay on the 9.6 Kb birds: I can copy from an elevation of about 15
degrees (- can hear the bird at 2 degrees elevation) - but the signal is
rarelyabove S1.5 on the IC475. Fortunately noise and interference is not a
problemhere on the Island. BUT - as soon as it gets above freezing I plan
to put a landwehr preamp up at the base of the antenna to improve the
stations performance on receive.
My question is this:
What cable/coax should I use for the patch cable between the antenna and
preamp. I would like to make the distance as short as possible - but too
short and even RG213 will not make the turn to get to the preamp input
without distorting the cable's properties. Is a 12 inch run of smaller cable
bad news? Should I use a longer run ofRg 213 or 9913? What would have the
least impact upon the preamp's performance?
I understand that flexible 9913 is used for the system using yagis - but
there the patch cable is probably in excess of 10 feet depending on the
setup. - Is flexi 9913 able to make a decent turn - so that a patch cable
in an omni system is a reasonable size?
Thank you for any information you might be able to provide me on what is
essentially a practical question.

To: ham-space@ucsd.edu
Anti spoofing is a system that degrades the GPS fixes of systems that
are not using the classified military codes for accurate, dynamic
navigation. i.e. to prevent anyone from using GPS as a means
of guiding weapons or aiming them.
Presumably 100 m is greater than the blast radius of a terrorist
bomb!

It could not be delivered to the following recipient(s):

In most cases, these delivery problems are caused by spelling errors in the

Its correct addressing is:

RFC-822: /X121=9xxxxxxxx/ADMD=arcom/C=ch/@chx400.switch.ch
Other reasons may be:
- non-authorized use of our gateway to ADMD=arcom: It is open for users with
X.400 addresses "...;PRMD=switch;ADMD=arcom;C=ch" *and* RFC-822 addresses
...@<somedomain>.ch only.
- an incorrectly encoded message envelope: Examples for this are missing
address attributes from some very old EAN versions.
- incorrect timezones in the header's tracing info:
We often see timezone +2900 (29 hours, 0 minutes ahead of Greenwich)

Subject: Oscar 13 questions
To: ham-space@ucsd.edu
Hi All,
As a "newbe" to satellite work, I am in the middle of assembling a
Oscar 13 station. I have enough power/preamps/decent rigs for the 2
meter uplink and 435 downling (and vice versa). One thing I'm lacking
is antennas for this effort. I already have the elevation rotor so I'm
about ready to go. I've been looking into antennas, and need some info
regarding them and circular polarization;
a) Is switchable polarization really necessary? Is there a
"standard" polarization setting for the Oscar birds?
b) I have diagrams to build quagi's for satellite work. What is
the current prices vs building a quagi like. I saw some ad's for
KLM antennas, and if I remember correctly, the prices were like
$150 + each. Even if I had to build a quagi a year, it would take
me quite a bit of time to use up $150 worth of materials!!
c) I saw an article in either Jan or Feb QST regarding 2304
downlinks. Are they used very much? Is it worth the effort and
cost to install a 2304 downlink? I live in a rather rural area,
so 2 meter interference isn't really a problem here, but was
trying to get a idea of the cost vs necessity of getting up on
2304.
Thanks and 73,
Joe KI3B
