To: ham-digital@ucsd.edu Phil Keys (philkeys@pt.olympus.net) wrote: : I haven't started packet yet but I am considering buying a mobile VHF/UHF : dual-band rig and have some questions. : Will most rigs support 9600 baud or only those that are "data ready"? : What features are required for reliable 9600 baud packet (max deviation)? Most mobile rigs work fine when modified for 9600 baud packet. If nobody has a mod for it then you can probably figure it out yourself since most radios are designed virtually the same as the others and use the same IC chips and the 'tap' points for 9600 are almost the same. About the toughest radio I've seem to mod for 9600 is a Kenwood TM-731A dual-and mobile, and mine runs just fine on both VHF and UHF at 9600. A 'data' radio optimized for performance is better though (like a Kantronics D4-10 or TEKK rig), but my TM-731A runs fine at a TXDelay of 8 (80 ms) and receive people fine when they run 4 or 5. If your rig requires a TXDelay of more than about 10 - 15 or so then look into something better. There's no reason for anybody to run TXDelays higher than about 15. If they need higher then there's something wrong, even an HT with a slow squelch will work fine around 15 and under. : Do crossband rigs offer any particular utility for packet? Depends how packet is done around your area. If people are spread out all over VHF and UHF, then having a dual-band is nice so you can float around (assuming a not very well connected network). Or you can run dual-receive and single transmit, which I've been running on and off when I test out modems. Another thing about dual-band radios. Seems that many, if not all, still have both bands receiving even if you turn a subband off. I can turn on UHF and disable VHF entirely, but the VHF receiver will actually still be running and if I have a 9600 modem hooked up it'll still receive packet on it.

I've been working on setting up JNOS and had some questions. I stumbled across a digest version of this group at sunsite.unc.edu:/pub/academic/agriculture/agronomy/ham/DIGITAL don't ask me about the path, that's where it is. FTP each of the files and you can view them with any UNIX-type mailreader (and there are DOS-based UNIX mail readers). I printed out about seven messages dating back to June of this year where people here answered the same questions I have now when someone else asked them months ago.. you might find help, too. And secondly, I think I found out what was wrong with my TNC. The user guide says to exit KISS mode by entering "host off" followed by 3 control c's. AEA tech support said 3 control c's. In a message I printed from the digest, someone mentioned the importance of hitting the 3 control c's and *waiting a full second* for command mode to return. That did it for me. However, later on, my input buffer filled in the TNC, and the TNC locked. I had to power down and kill the battery backup in the TNC. Thanks, sunsite, for digesting this stuff. -- Steven Jackson, Assistant to the Chair of Computer Science Courant Institute of Mathematical Sciences, New York University 251 Mercer Street, NY NY 10012 +----IMPORTANT:-----+ |<-----------These 2 DEAD after 9/23/94--------->|<-starts 9/24/94-->| | Work <-- (forwarded) | | |jackson@cs.nyu.edu, jcksnste@acfcluster.nyu.edu,|jacksons@cs.nyu.edu| +------------------------------------------------+-------------------+ ------------------------------ Date: 23 Sep 1994 18:33:46 GMT From: enews.sgi.com!sgigate.sgi.com!sgiblab!swrinde!howland.reston.ans.net!news.sprintlink.net!tequesta.gate.net!hopi.gate.net!anto@ames.arpa Subject: KPC 9612 To: ham-digital@ucsd.edu Kenneth E.

Any comments about >the best equipment or personal experiences would be greatly >appreciated. I run a Mac on packet at my home QTH. I use a KPC-3 (around $90) and the Z-Term comm program, which is the same program I use for the land- line modem. I started out using the comm. program from claris works and it works well, also. I also use my mac to decode WEFAX, which is kinda cool, also. 73's N0UJT ------------------------------ Date: 25 Sep 94 15:36:42 GMT From: news-mail-gateway@ucsd.edu Subject: your LISTSERV request "info wanted on commercial packet radio network" To: ham-digital@ucsd.edu File on does not exist. ------------------------------ Date: 25 Sep 94 15:36:45 GMT From: news-mail-gateway@ucsd.edu Subject: your LISTSERV request "info wanted on commercial packet radio network" To: ham-digital@ucsd.edu File radio does not exist. ------------------------------ Date: 25 Sep 94 15:36:40 GMT From: news-mail-gateway@ucsd.edu Subject: your LISTSERV request "info wanted on commercial packet radio network" To: ham-digital@ucsd.edu File wanted does not exist. ------------------------------ Date: 25 Sep 94 15:36:44 GMT From: news-mail-gateway@ucsd.edu Subject: your LISTSERV request "info wanted on commercial packet radio network" To: ham-digital@ucsd.edu File packet does not exist. ------------------------------ Date: 25 Sep 94 15:36:43 GMT From: news-mail-gateway@ucsd.edu Subject: your LISTSERV request "info wanted on commercial packet radio network" To: ham-digital@ucsd.edu File commercial does not exist. ------------------------------ Date: 25 Sep 94 15:36:47 GMT From: news-mail-gateway@ucsd.edu Subject: your LISTSERV request "info wanted on commercial packet radio network" To: ham-digital@ucsd.edu File network does not exist. ------------------------------ End of Ham-Digital Digest V94 #320 ******************************
