The reply are evenly matched for and against such activitys (see previouse post). I would like to say a few words on my behalf. I am aware on the fact when I do this activity I do tie up nodes. So I do this activity lat at night usaly starting around 00:00hrs pac. and some time go as long as 05:00hrs pac. I do this at theise times for two reasons: 1, there is little packet communications going on in my area at this time. 2, I run low power and often get stomped on by higher powerd stations durring the peek hours. There has bein the comment to call out CQ when I get to a new node, I've tried that but usaly no one's up that late. If the owners of the nodes think I'm a nucence they can kick me off, thats their perogrative. Usaly when I get out far enouph I usaly time out some where along the line anyways. I node hop like this becuase I like to see how far I can get if need be. and I usaly set a goal in seing if I can get to a certain city (current one St. Joeseph MO, I have family threre). Thank you for your responces. Some of them I found quite entertaining, I'm glad that they were all polite in wording. -Micah- *KD6PJM* Ps. The question concerning if there were node or bbses in or around St. Joeseph MO was never answered. ------------------------------ Date: Thu, 11 Aug 1994 17:00:57 GMT From: gatekeeper.us.oracle.com!barrnet.net!rational.com!jal@decwrl.dec.com Subject: PACTOR/AMTOR subbands...where? To: ham-digital@ucsd.edu I am still an HF newbie and with the current state of the bands, it's not easy for us newbies. Last night while scanning around what should be the CW portion of the 40 meter band I heard a QSO between an Hawaiian station and some foreign station. Als the Hawaiian station claimed he was going to QSY back to a quiet spot he had found between two AMTOR subbands. My question are two: 1) How can a Hawaiian, which despite Dan Quayle not understanding is part of the US, transmit phone in a non-phone portion of the band. 2) My only reference for digital subbands is a handbook on digital published by the ARRL. It lists only one subband for AMTOR per band. Are there more subbands. Where can I find a current subband listing? Is the AMTOR subband the same subband as RTTY and PACTOR. I know that there is no such thing as a digital subband but you know what I am referring to.

The space below the RTTY section is where people do Amtor/Pactor/Gtor. The space above the RTTY area is where packet is commonly run. On 20 meters, 14.065 or so to 14.080 is where the Gtor/Amtor/Pactor modes are used, the 14.080 to 14.090 space is for Baudot (and you'll find a lot of DX on Baudot in this space) and above 14.095 is where there's a lot of packet. Layouts are similar on other bands... The fully automatic HF NPRM will likely cause a shift in where the packet signals are, since they'll be in limited subbands (along with any other mode being run full-auto) once that NPRM becomes part of the rules. -- --------------------------------------------------------------- Daniel Senie Internet: dts@world.std.com Daniel Senie Consulting n1jeb@world.std.com 508-779-0439 Compuserve: 74176,1347 ------------------------------ Date: 12 Aug 1994 23:55:51 -0700 From: ihnp4.ucsd.edu!dog.ee.lbl.gov!overload.lbl.gov!agate!news.ossi.com!news.fujitsu.com!amdahl!pacbell.com!UB.com!kaiwan.com!kaiwan!dmercado@network.ucsd.edu Subject: PCMCIA TNC?

Subject: PKGOLD Enhanced PROBLEMS To: ham-digital@ucsd.edu TO ALL HAMS USING PKGOLD ENHANCED I have ran into a problem with the latest version of PKGOLD Enhanced with Pactor. It seems to exit the program with the following: DISK ERROR 100 DISK READ error record -1 in GOLD.BD This is found on the screen after the program dumps out. Timing of the exit from the program is random meaning 5hrs or 1hr after loading the program and has even done it while in the connect mode as well. It will leave the TNC open so that the buffer fills up and no connects can happen. Having the ***SAME*** version for the Kantronics TNC (KAGOLD) for use with the KAM+ and the KPC models and using the ***SAME*** computer ***WITHOUT*** ONE problem at any time and I can leave it without worry PKGOLD I can not do that at all. (also tried it on other computers with the same results) One other problem I have notice is that opening a connect window it is full of junk chars which should not be there. ?????????? (PKGOLD ONLY) Interfex claims it doesnt have any problems and thinks it mine. Why can I run the same versin for the Kantronics TNC without any problems but yet I can not run the PKGOLD (extra cost) with the AEA products. (PK-232, PK-88, PK-96) Also how many commercial programs leave out the manual because you have it with your other versions of gold Has anyone seen or have the so called DUALPORT PKGOLD yet.

I understand that Windows 3.1 or WFW can use TCP/IP networking with the WINSOCK.DLL. This provides TCP/IP networking services to an Windows TCP/IP application. Whatever networking medium used requires a driver, ie SLIP/PPP, ethernet, token ring, etc. Ham/packet radio also uses TCP/IP as a protocol in local area networks. I have a Baycom modem and plan to use the AX.25 driver withthe DOS program KA9Q NOS to access the local TCP/IP packet network. My question is: Is there a way to tie the Baycom modem into Windows 3.1 or WFW? You could then use the TCP/IP applications over pacet radio just like you would over an ethernet or SLIP/PPP, only much slower. I think you would need a packet driver like the etherne cards require. Has anyone got any information on this? If I get any responses, I will combine and post to this list. THANKS IN ADVANCE!! Andrew Lynch, N8VEM alynch@wpgate1.wpafb.af.mil PS. I have searched the ham/packet FTP archives for this and did archie searches as well, with no luck. I suspect nothing like thi exists. I realise this may be esoteric, but I think this would be one very interesting technical project. If there are any ham/paket radio enthusiasts looking for a challenge, who are also Windows expert programmers, this project may be for you. This project pobably would require programming experience writing windows drivers therefore this is WAY out of my league. There are DOS programs which do this in existence, with source code, so I think its *theoretically* possible. If Windows WINSOCK.DLLprovides the TCP/IP services, I think all thats needed is a Windows packet driver for the Baycom modem. The Baycom AX.25 driver forDOS (NOS) includes documented assembler source code, but no doubt a Windows version would be VERY different. Send me email if you would like to discuss more. 73!! ------------------------------ Date: 12 Aug 1994 23:56:16 GMT From: newsgw.mentorg.com!wv.mentorg.com!hanko@uunet.uu.net To: ham-digital@ucsd.edu References <32bj9r$861@search01.news.aol.com>, , <1994Aug12.154901.27305@ke4zv.atl.ga.us> Reply-To : Hank_Oredson@mentorg.com Subject : Re: Packet Node Info Wanted In article <1994Aug12.154901.27305@ke4zv.atl.ga.us>, gary@ke4zv.atl.ga.us (Gary Coffman) writes: |> In article JAY@medicine.dmed.iupui.edu (Jay Sissom) writes: |> >Interesting, an Amateur Radio mode where DXing is discouraged!

The properties that makes it desirable are : Protection against jammers. This is measured in the AJ (anti- jam) ratio. Some simple math shows how much more jammer energy is needed to cause bit errors(digital communications) Low probability of intercept. SS signals can be placed below the noise floor in many cases. This means that covert operation can be conducted with some communications. Most people confuse the encryption with the last one. If the method for spreading and the code is known, a little bit of work will show you the signal. For more information I believe Sklar's "Digital Communications" has a chapter on it.
