It's illegal to use the Amateur Radio freqs for business purposes. A bigger concern is through-put. Most plug-and-play stuff ( 1200b ) get's you under 100 chars/second. Try sending a large file at 100 cps. You might be able to get some 19.2kb stuff going but it is still really SLOW compared to Internet Standards. If you want to move alot of data and you don't have to go very far ( line of site ) you can use 10Ghz and do 2 mega-bit stuff. I think that this is similar to the Commercial, Broad-Band stuff. I'm note sure what the rules are for general communications in the 10Ghz area. You may not need to be a ham to use some of the Microwave freqs using low power. Most of the 10Ghz stuff is low power. It's very directional and very short range compared to the other bands. It takes a lot of time and energy to scroung up 10Ghz parts. There's very few hams doing that sort of stuff. If you don't mind slow speed, you could probably get away with a pair of business-band talkies and a pair of tncs. Total cost would be under $600 new. The Tnc's are around $115 new. The talkes are $100 - $200 or so. If you used these, you wouldn't need to worry about doing business over amateur radio, because these are on non-ham freqs. Not 100% sure that packet is ok on these freqs, but I think that it is. Do you really want 100 cps ( more like 60 cps ) though? > >1) Is there a FAQ? Yes. Somewhere. Usually posted here I think. >2) Is there an easy way to connect to the "rest of the Internet" from the ham > network? Yep. Telnet to dfwgate.ampr.org ( it's down at the moment but it will be back.) It is an Internet/Ampr.Org gateway. The Ampr.Org is the Amateur Radio domain. >3) What kind of hardware do you need to start up? What does it cost? see above. >4) Is there software available to work with TCP/IP under UNIX? Yes. NOS. >5) What kind of throughput can be expected? (Assuming an RS-422 serial port) See above. The computer is not the limiting factor. The RF Modems are generally pretty slow. > 73's de Jack - kf5mg AX25net - kf5mg@kf5mg.#dfw.tx.usa.na - (817) 962-4409 Internet - kf5mg@kf5mg.ampr.org - 44.28.0.14 Worknet - kf5mg@vnet.ibm.com ------------------------------ Date: 28 Oct 93 17:12:15 GMT From: ogicse!uwm.edu!linac!att!cbnewsm!jeffj@network.ucsd.edu Subject: Interesting things done with Packet Radio?

The KPC-3 has what is known as "firmware", the software stored inside the unit itself, and that is the software that should be version 5.0 or 5.1. Kantronics ships a terminal program with the KPC-3 called PacTerm, and that is the software that should be version 1.02. I don't have the manual with me at the moment, but I think if you can get to a cmd: prompt try the command VER to see what version of firmware is in your unit. PacTerm is just a communications program - you do not need to use it to use your KPC-3. I use the KPC-3 on both Macintosh and Windows boxes running the appropriate versions of Smartcom, a terminal program from Hayes. Any terminal program should do - there are even specially designed packet terminal programs (that are all a lot better than PacTerm) like PacRatt for DOS, Windows, or Mac by AEA, or Savant for the Mac (I forget who sells this).

That may be so, but if it is, the wiring shown in the KPC-3 manuals for an IC-2AT is wrong. Here is the way I wired my KPC-3 to work with the Radio Shack HTX-202: D-9 PIN# 1 -> .1 uF cap -> 7 3 -> 3300 ohm resistor -> pin 7 7 to tip of small (3/32) plug. 5 to tip of larger (1/8) plug. 6 to sleeve of small plug. 9 to sleeve of larger plug. as shown in the KPC-3 manual, the D-9 radio connector is wired like this: Pin 1- AFSK out Pin 2- XCD (squelch-not needed) Pin 3- Push to Talk Pin 4- Audio in (from radio) Pin 5- Audio in (from radio) Pin 6- Ground/shield Pin 7- Default is open-can be configured with wire jumpers to do a 'hard reset' by grounding pin 7. Pin 8- Ground/shield, same as Pin 6 Pin 9- Ground/shield, same as Pin 6 Note: A jumper in the KPC-3 (J2) can be used if you're using only an H.T. that requires the capacitor and resistor. The value of the resistor in the KPC-3 is 4700 ohms, which did not work with my HTX-202. It needed the 3300 ohm. I used pin 7 as a convienient tie point to install the resistor/capacitor. I could have changed the value of R4 in the KPC-3, but I set my stuff up to use numerous different radios.

If you can capture one of these mysterious smtp connects, you can 1) see who it is exactly and what gateway or router they are using ( if any ) and 2) see where/how your box responds. If it's a routing problem, you'll be able to tell something from the trace. If the stuff is comming from the 44.X.X.X router and your responding through the 44.X.X.Y router then you'll know it. The trace may be very usefull. You turn off the trace using 'trace portname 0'. 73's de Jack - kf5mg AX25net - kf5mg@kf5mg.#dfw.tx.usa.na - (817) 962-4409 Internet - kf5mg@kf5mg.ampr.org - 44.28.0.14 Worknet - kf5mg@vnet.ibm.com ------------------------------ Date: 25 Oct 93 15:24:45 GMT From: galaxy.ucr.edu!library.ucla.edu!news.mic.ucla.edu!magnesium.club.cc.cmu.edu!pitt.edu!dsinc!spool.mu.edu!howland.reston.ans.net!pipex!uknet!root44!praxis!mikec@network.ucsd.edu Subject: THS Program for WA8DED Hostmode?

I have two questions that I hope people can help me out with: 1) When I make the cable to connect the DX-440's audio-out (a mono headphone jack) to the DB-9 connector, do I just connect pin 7 to the tip and pin 9 to the shield? Or do I need to put some resistors or capacitors in the line? The manual is not too clear about this, and although I think I would be all right to just connect the two wires straight through, I thought I would ask. Also, am I safe to assume that using old coax as the line is possible, as I only need to connect to two pins? 2) What is the best shareware/freeware/public_domain wefax decoding program available for dos/windows or the mac? (I'm currently using a windows box, but I have a mac waiting for me at school.) And where can I find these programs? Or are there worthwhile commercial alternatives?

In his original post, he mentioned "ham radio" twice. A prudent individual would assume that when he left the word ham off of the later references to radio he was still talking about ham radio, but then that is open for interpretation. AX.25 protocol is being used on commercial frequencies in the States and has been for many years. In fact commercial users were using amateur TNCs at one time, but I haven't been involved for quite a while so I don't know if they still do or not.
