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" 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.

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. 73 David, VY2DCS Internet: Seeler@upei.ca ------------------------------ Date: 17 Feb 94 00:11:53 GMT From: munnari.oz.au!newshost.anu.edu.au!sserve!usage!metro!news.ci.com.au!eram!dave@network.ucsd.edu Subject: Daily IPS Report - 17 Feb 94 To: ham-space@ucsd.edu IPS RADIO AND SPACE SERVICES AUSTRALIA Daily Solar And Geophysical Report Issued at 2330 UT 16 February 1994 Summary for 16 February and Forecast up to 19 February IPS Warning 05 was issued on 14 Feb and is still current. ----------------------------------------------------------- 1A.

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.
