Here, we have assigned liasons between our local NTS BBS (K1UGM.MA) and both nightly NTS nets (EM2MN at 20:00 and HHTN at 22:30). At most, a message will sit around for one day waiting to be picked up (but many traffic handlers will grab any traffic they can handle whenever they check in) This definitely helps keep the traffic flowing. 73, /mike N1IST HHTN NM -- \|/ Michael L.

NOAM is the packet radio code for North America. They are not from the same naming scheme, although making the distinction avoids accidentally using NA in an internet message. NOAM is not a registered top level domain on Internet. If the two naming systems were to be integrated (a good idea, but some people disagree), the packet names would probably be of the form ......USA.NOAM.???.ORG.

[I'm surprised CLOVER did not do better.] Based on this and other published data, the throughput (CPS) for various protocols on HF would appear to line up as follows: AX.25 Packet 4, AMTOR ARQ 5, RTTY 6, PacTOR 9-10, CLOVER 16, and G-TOR 24. By the way, I don't think the Kantronics KAM used in Westhuizen's tests implemented hardware ADC Memory ARQ. Furthermore, the various throughput data cited above were not taken by the same experimenters under similar conditions, etc. Of course, there are many features that differentiate the different protocols beside typical throughput, not the least of which is throughput normalized to bandwidth, i.e., CPS per hertz. And the maximum throughput may be much higher than the throughput measured under typical conditions (if there is such a thing as "typical" conditions on HF!). Comments anyone?

Well, it is possible to access a Waffle BBS via packet. The problem isn't technical so much as legal. You can't have business traffic on amateur frequencies, so you or someone else would have to monitor stuff pretty closely.

(was Re: [REPOST] NTS Traffic on Packet) A dumb set of questions regarding BBS and NTS, with a follow: (1) Would there be enough NTS traffic to warrant a set of NTS only (or at least NTS priority) BBS systems across the country to forward NTS-type traffic? (2) I how much time, effort, and cost is involved in running a BBS? I ask not to point any fingers, but because I can't fathom what the costs would be. I can think of there being the expense for a good antenna, a reasonable 2m rig (50 watts?), a reasonably fast computer (486 of some flavor) with a decent size hard disk, that this power-hungry computer (400 VA watts?) would be running 24 hours a day, your time and effort in seeing that the computer and radio keep running. I suspect MUCH IS already being given by BBS operators as a service, but I'm just curious of the accounting. Maybe a few statements by BBS operators will enlighten more than a few of us of the services we use and keep asking for without thinking about hidden costs, or at least costs we've individually externalized. Amateur radio is very much a hobby of willful giving and sharing, and we shouldn't come to expect when expectations shouldn't be there. At the same time, though, I would hope some compromise/working solution can be found between NTS and BBS operations, which is what prompted me to post. Enough said. Off the orange crate.

At most, a >message will sit around for one day waiting to be picked up (but many >traffic handlers will grab any traffic they can handle whenever they check in) I am trying to get this set up in West Mass as well. One problem I do see is that the BBS community sets up new BBS's, turns on NTS handling abilities, then expects that the NTS folks will somehow find those new BBS's and check for messages on them. The BBS constructing folks really need to talk on occasion with others to let others know what's up. The problems with NTS use of BBS's are not the fault of the BBS folks or the NTS folks exclusively. The groups need to talk and make sure they are in sync. The alternative is visible as "status-qou" in most parts of the country, where each group complains about the other. > >This definitely helps keep the traffic flowing. > >73, >/mike N1IST HHTN NM > 73, Dan N1JEB SM WMA -- --------------------------------------------------------------- Daniel Senie Internet: dts@world.std.com Daniel Senie Consulting n1jeb@world.std.com 508-779-0439 Compuserve: 74176,1347 ------------------------------ Date: 28 Mar 1994 18:46:44 GMT From: nothing.ucsd.edu!brian@network.ucsd.edu To: ham-digital@ucsd.edu References , <764402457snx@skyld.grendel.com>, <764721388snx@djwhome.demon.co.uk> Subject : Re: [REPOST] The # in PBBS addresses.... david@djwhome.demon.co.uk (David Woolley) writes: > >NOAM is not a registered top level domain on Internet. If the two naming >systems were to be integrated (a good idea, but some people disagree), >the packet names would probably be of the form ......USA.NOAM.???.ORG. Actually, the transformation is a bit more complex process, but yields a less complex result. Any hambbs-to-internet gateway which forwards mail will be required to 1) be fully registered (both A and MX records) with the AMPR.ORG domain server. 2) be able to utilize MX records for mail exchange on the internet. 3) be capable of accomodating a routing table large enough to handle all the ham packet BBSs that will be routing to the internet through it, and automatically update that table. 4) be able to generate MX records as required and submit them to the central ampr.org database maintenance robot, either automatically or by hand. The procedure is: When mail arrives from an AX.25 bbs at a ham-to-internet gateway system, the gateway 1) updates its routing table for that BBS to reflect the routing hints contained in the return address. E.g., mail arriving at the WB6KDT gateway FROM WB6XYZ@WB6CYT.#SOCA.CA.USA.NOAM generates a routing table entry of WB6CYT #SOCA.CA.USA.NOAM 2) the bbs from line is rewritten* as From: WB6XYZ@WB6CYT.AMPR.ORG and the mail is injected into the internet 3) An MX record for WB6CYT.AMPR.ORG is established (if it does not already exist)**, pointing to the gateway system (in this example, WB6KDT.AMPR.ORG) with a preference value equal to the number of stations the message took to make it to the gateway from the bbs where it originated. Yes, it's a bit elaborate. But it's RIGHT. It's clearly the way it ought to be done. Let's do it. - Brian * Yes, rewriting addresses is supposed to be a sin. It's unavoidable when you change addressing methods between networks, so in this case we have to do it. I don't like that either but there's no choice. ** Yes, there's a timing problem here if a reply message is sent before the nameserver gets updated and propagated. It's a one-time problem, though, and could be solved by pre-registration. After all, how many BBSs are there near each gateway system? ------------------------------ End of Ham-Digital Digest V94 #85 ****************************** ******************************
