I want to be a packet ham. I am at Xalapa, Veracruz, approximately 400 miles south of McAllen TX. My need is for a connection by the HF frecuencies, but i need to know first: Is it possible to get a connection in HF within the 400 miles range?? and, if possible, what equipment i should have? I am a long time user of the ka9q NOS system. If you have a solution for this in packet satellite please let me know.

The entire 4-character system was first proposed by Tom Clark, W3IWI, in 1990 in a paper in the proceedings of the 9th ARRL/CRRL Computer Networking Conference in London, Ontario. In this paper, Tom called for the elimination of continental designators; that systems simply route on the ISO-3166 ALPHA-3 code. This system was presented as a fallback position should there be a truly good reason to even have continental designators, at all. To date, the "best" reason I have heard is that some HF forwarding stations refuse to handle messages without the 2-character designators:-(. Through the 11th Conference (last proceedings I have in hand) with the exception of the one paper at the 7th Conference that first detailed hierarchical routing (or naming as the case may be) any paper that has expressed a view on continental designators has supported their elimination (including my own). >Personally, with the legal problems with Inet->packet and packet->Inet >gatewaying, I think the better compromise would be to go with the >4-character designators, as I'm not sure we want to make the packet >network look like 'just another part' of the Internet.

Trimming the PBBS system names to end with the ISO-3166 ALPHA-3 codes I feel is an even better compromise than the 4-character designators as they convey the required information and are clearly distinct from the ISO-3166 ALPHA-2 codes used on the internet and are non-intersecting with the existing 3-character top level domains. >Ben >+---------------------------------------+---------------------------------+ >| Ben Coleman NJ8J | "All that is not eternal is | >| AX.25: NJ8J@W4QO.#EAL.#ATL.GA.USA.NA | eternally out of date." | >| Internet: ben@nj8j.atl.ga.us | C.

Then why is the .NA required? Just ask anyone in the teaching profession. Apparently most people under the age of 30 these days have a hard time locating North America on a map. The .NA is "required" beecause people think it is required. Another effect of amateurs copying something they didn't take the time to fully understand before they did it.

Hey, I suggested the same thing on our local tcp/ip mailing list. This discussion has been going hot and heavy on the local LAN in Arizona and New Mexico. I wish that the subject line would change and drop the "wb7tpy gateway" ...
