To: ham-digital@ucsd.edu I'm looking for some kind of a directory to assist in addressing messages. What I'd like to see is a directory in which one could look up, for example, a city, and get: 1. A list of the BBSs that serve that city 2. The flood address hierarchy for the city One could also look up a flood address and find the BBSs that contain it. The problem I'm trying to solve is that of getting a message to a particular geographic area when I don't already know the address for the area. The US convention, using state postal abbreviations for flood addresses, is fine if the area of interest is a state, and if you happen to know the abbreviation. For someone outside the US, neither of these may be true: the packet user may be looking for someone in Dallas, but not know the state abbreviation for Texas or even that Dallas is located in Texas. Similarly, I have no idea how to get a message to all BBSs in Sydney, for example. Does such a directory exist already? If not, would anybody on the net find such a directory useful if it did exist? At minimum, I expect that easy access to a directory of this sort would cut down on the number of messages intended for one particular country that are addressed to @WW. -- Bruce Toback KN6MN@KC7Y.AZ.USA.NA btoback@netcom.com ------------------------------ Date: Thu, 23 Dec 1993 16:58:18 +0000 From: swrinde!cs.utexas.edu!howland.reston.ans.net!news.intercon.com!udel!news.sprintlink.net!demon!fantom.demon.co.uk!andyh@network.ucsd.edu Subject: Packet frame check sequence help please?

I'm trying to get into packet radio, but know not too much about it. I'm trying to go the cheap route, so I got the schematics for the Baycom modem using the TCM3105, and Baycom 1.5 software. My question is, what frequencies are normally used for packet radio at 1200 baud (that is what the Baycom modem is at right)? My radio is 2 meter, but I understand some transmissions are in the FM range. Is 2 meter for 9600 and FM for 1200/300? Lemme know, so I'll know whether to build this or not. On the 2m band, the standard baud rate is 1200. Hams are beginning to experiment with 2400 baud on this band, too. On the 1.25m and 70cm bands, the baud rate can increase dramatically, provided you have the modem to work at those baud rates. Plus, are there any more schematics out there for a better modem than this? Perhaps some with DCD? Any usual schematics format (preferably schema) or even a PS file would be nice. The faq failed to mention any relevant info on any of these topics...or any anon. ftp sites for that matter. What other software can I use the Baycom modem with? I'll let others on the net answer the rest of the questions.

Yes, they are used for radio control of miniature aircraft, ships, cars, etc. To put someone's precious toy aircraft at risk isn't exactly a nice thing to do. It's much better to connect a TNC or Baycom modem to mic input/output of the CB set. Then you can use the legal channels without modifying the set. It works good enough for me and lots of other people.
