Need to get something for working at home, and I thought I'd try to combine a little business with pleasure. So the computer will be in the shack, next to the rig. I've been looking at various 486 25mhz boxes, including Compaq, Laser, and Packard Bell. Are there any that are notoriously bad radiators of RFI? I'll be looking for a TNC and software as well. I want to use the two for VHF/UHF packet, and HF digital modes too. I'm also interested in what else the two can do for me with logging, station control, etc... I've got a Yaesu FT747GX, which has the CAT control port. I was leaning toward the AEA PK-800 (or is it 900) and PAKRATT/windows, until I saw the new MFJ software advertised in the Nov QST. It looks like it'll do everything that I want and then some. Any comments?

AMTOR is the amateur version of SITOR, the commercial ship to shore system. It's defined by the CCIR as using international telegraphic alphabet number 2, IE Baudot. Packet on the other hand has no such alphabetic restriction. It's defined as transmitting "octets", IE 8 bit data combinations. 7 bit ASCII *fits* in an octet with room for a parity bit, so it's most often used as the telegraphic alphabet with packet, but packet isn't limited to ASCII.

It turned out that the dip switches on the back (used for setting baud rates etc) had been installed up-side down.

The number of people kind enough to respond makes a direct response to each difficult. I appreciate the suggestions some of which I had already tried but some were new. The connection still isn't working. I'm now going to try the break-out box although I'm not sure why my cable works with the modem but not with the TNC but who knows. It is interesting that one respondent says that the 1270B definitely uses 7E1 while the multicom documentation from MFJ says to use 8N1 for the 1270B. The documentation for the TNC is somewhat confusing it says the AWLEN is by default 8 but it says to use 7bit in the commo package. However, regardless of that I had already tried them both and neither did anything when it comes to allowing communications between computer and TNC. I guess I'll make the break-out box the last try and then bag it figuring the new TNC is defective. Given the overall quality of this MFJ item, it could well be. But whatever comes of it, I appreciate all the suggestions from the net. thanks, Erich N3OXM ------------------------------ Date: Wed, 3 Nov 1993 08:05:36 GMT From: pacbell.com!att-out!cbfsb!cbnewsg.cb.att.com!fvdbord@ames.arpa Subject: Viruses and Packet radio To: ham-digital@ucsd.edu If I use Baycom for Packet radio and I set "remote off" is there any chance that anyone can install a virus on my PC from a remote system?
