Just about everything else. Remember most of these have 8 bit
micro's in them that are not useful for anything else. Buy an used
one if you really want to go this route. You can use it in your mobile
for APRS (maybe).

As with anything, the answer is: "it depends on what you want to do on
packet".
If it's APRS *from your home*, then you don't need a TNC anymore. Go to
the TAPR website and subscribe to the APRS SIG (special interest
group). It's a listserve for that interest-area. The authors of
WinAPRS just announced that their product now supports SoundBlaster
cards instead of TNC's.
If it's APRS *from your car*, then the best is the Kantronics KPC3+ with
ROM 8.3.
If you want to start playing with PropNET (a service that uses APRS
protocols to chart propagation anamolies and meteor scatter contacts
using packet technology), then the best TNC is the Kantronics KPC3 or 3+
with ROM 8.2 or above.
I guess this means, if you need a TNC, make it a Kantronics. A close
second is the Paccomm units with latest ROM. Everything else comes
next.
Of course, these are generalizations that may need modification, based
on your actual usage; but this is a good place to start.

As you can see from the postings it really does depend what you want to do
on 2 mtr packet.
Talk to you local HAMS and find out what is happening in the local packet
scene. Even though many nodes or digipeaters are coming down, many places
still have BBS's, DX clusters, internet gateways and TCP/IP JNOS stations.
Yes, You can easily use a sound card for 1200 baud packet and sometimes the
sound card will work for 9600 baud packet. But you will need to build a
small circuit the interfaces your computer's serial port to the rig's PTT
line in order to key the rig on transmit. The circuit is very simple - only
1 resistor, I diode and 1 transistor.
If you don't have a sound card, you can use a BAYCOMM modem. Tigertronics
sell BAYCOMM modems under the trade name BAYPAC. It is a very simple modem
but the packet protocol is implemented in the PC NOT the modem. (i.e. the
PC must always be on for you to use packet). Much cheaper than a regular
TNC such as KPC3 or MFJ etc.
But some people like keeping their packet station running all the time
especially if their local BBS does reverse mail forwarding. If you want to
keep you packet station running all the time, you may want to consider a
standalone TNC such as MFJ, Pacomm or Kantronics. You won't need to keep
you PC on all the time -- only your TNC and Rig.
If you want to run 9600 baud packet (but check first to see if there is any
9600 baud activity left in your area), you will need a rig that is 9600 baud
ready or you will have to make a mod to your existing rig.
I have a KPC3, it is a simple TNC and works well BUT it is not TAPR TNC2
clone compatible. The TAPR TNC2 clone has become almost a defacto
standard.
Unlike the Kantronics TNC's, the MFJ and Pacomm TNC's are TNC 2 compatible
and support the WA8DED host mode. There are many great terminal and BBS
programs out there that support the WA8DED host mode. A lot of them are
free!
Some people also like the MFJ or Pacomm units over the Kantronics since they
can easily change the EPROMS in the TNCs with any one of the multiple of
free EPROMS out there designed for the TAPR TNC2. Some of these EPROMs
include The Net X1J4 (very common node for routing), 6PACK so the TNC can be
used with FlexNet software, etc.
You can even change the EPROM in a MFJ or PACOMM TNC to run a different OS
in the TNC such as the TAPR firmware or the NORD<>LINK's "The Firmware
TF2.7b". (But I don't know whether such a change is worth it).
To change the EPROM, typically all you need is to find someone who will burn
the EPROM for you. (the images for the EPROMS can be found on the
internet). Buck Rogers (www.packetradio.com) will burn EPROMS for the NET
X1J4 and may even burn other EPROMS for you.
I hope this helps.

Proprietary does not mean unpublished. You can publicly document the
protocol (thereby meeting FCC requirements) and still retain the
exclusive legal rights to it.

Not True.
As of November 1st we can use proprietary Spread Spectrum schemes on
70cm and higher. Most of us wouldn't know how to homebrew the protocol.
Thus, the only way you can decode the transmission, is with another like
product.
Case closed, argument over.

Subject: WTB: KAM Plus
Here I go again folks:
I had a deal set up but it fell through - so – once again:
I am looking for a late model, KAM Plus TNC/MCP with version 8.x
firmware. I would like the interconnect cables that come with it,
documentation and wall transformer too.
Please e-mail me if you have one you are willing to part with. State
condition, description and asking price.
Thanks: Jeff – KA9S
