I do not wish to address your personal attack on Jim Fortney other than to assure that I prepared the drafts of the reports based upon the discussion conducted by the Committee Jan 7-9 in Cleveland. Jim did critique the draft, as did all members of the Committee. The Band Plan and other remarks represent the collect thought of our Committee at that point in time. Based upon further data, particularly investigations underway to assure that the technical objectives are appropriate, it may be that there will be some changes the will be incorporated into the final report. You, or any other reader, are welcome to provide input into this process.

Signal encryption, so only A and B can chat, no one else can listen to. Amateur frequencies and bands are strictly shared, with no provisions for either message or conversational privacy. The FCC Rules prohibit codes and ciphers, and also require that ID be done in either voice or Morse Intl#1. If you need privacy, moe to a common carrier or commercial system where such technology is both available and legal (it's not legal in CB/GMRS either!). > 3.

TNCs are inherently and by definition digital devices, with no voice capability. The ones I've seen on the market today do not offer automatic mode detection and switching from packet to RTTY, Morse, AMTOR, or FAX modes. > 4.

There are several simple interconnects from various suppliers, most of whom advertise in all the major ham magazines, to allow communications through a local radio to a portable or mobile. All communications come under third-party rules, since the caller is assumed NOT to be a licensed amateur. > > May be I am dreaming, but with recent electronic and digital technology > evolution, I believe above feature can be integrated into one total radio > system.

The international Maritime service is considerably different from ham radio, both in usage and regulatory structure. Actually it sounds like you are trying to operate your amateur station like a smart multi-mode cordless phone for personal and possibly business use. Even with the recent rules changes, business use is prohibited. I hope I'm reading far too much into your comments. > > +-------------------------------------------------------------------------+ > |Johnny C.

I am an experienced system administrator, however, I have very little experience on the radio side. Can someone point me in the right direction? I'm looking for white-papers, howto's, FAQ's and any other material that can help me to get started. This will be strictly for my personal use at home. I definitely need full service TCP/IP so that I can pull news and ftp files, run Mosaice, etc. Thanks, Roger Spicher rspicher@ml.com ------------------------------ Date: Fri, 11 Feb 1994 20:35:28 GMT From: netcon!bongo!netcomsv!netcom.com!slay@locus.ucla.edu Subject: MFJ 1278B vs Kantronics KAM+ To: ham-digital@ucsd.edu Scott Barnett (srbarnet@nyx.cs.du.edu) wrote: : Hi All, : I am looking at getting a TNC to do packet with, but I thought maybe to get : a multimode because I might want to get into other digital modes in the : future. I have looked at the MFJ 1278B and like what I see. Also, a friend : suggested the Kantronics KAM. Which do you think would be better. This is : to use with a Realistic HTX-202 2 meter FM HT. Or is there another one : you like better? Whoa - looks like we have a major problem here. First, if you plan to use ONLY your 2M FM HT, you are wasting a lot of time and MONEY looking at a Multi-Mode Controller. You will NOT be able to use the wide range of features in the MMC with just your HT. Virtually ANY 1200bps TNC (TNC-2 type) will be all that you need. The MMCs like KAM and MFJ-1278 etc rally shine on the HF bands. I have and use BOTH the KAM and MFJ-1278T as well as a pocket TNC for portable use. If you want to do the SSTV and FAX modes, the MFJ-1278 is the way to go. I personally prefer the KAM these days because I want and need the dual port capability. I want to be connected to the DX PacketCluster on VHF at the same time that I am on CW, FSK, etc on HF. The MFJ-1278 does not have the dual-port function. I frankly have a quite a bit more invested in my MFJ-1278T (w/extra ram and 9600bps modem, host mode s/w, etc) but for ANYONE interested in DXing and using PacketCluster - the KAM is the ONLY way to go - IMHO.

This card is just what we need for our packet gateway! We will use the 56k baud async port to connect us to the Internet feed while we hope to use the 9600 baud port for a 9600 baud packet port. Obviously we will be running NOS as the software for the gateway. Therefore, I would like to know if the PI card will do this? I would appreciate receiving any information relative to the PI card.
