What's the current hotness for a TNC?  Prefer something portable, but it isn't necessary.

Thanks

Depends on how capable you want it. TinyTrak has a small portable unit for APRS that will function as a TNC. IIRC it's the TT4 model.
If you are looking for an old school TNC then MFJ, AEA and Kantronics are about your only choice.

Do people not do data anymore?  I would have thought that in this day of SDR it would be more prevalent.

I use soundmodem on a raspberry pi and YACC for mobile APRS

Soundmodem plays the tones over a sound card, I prefer a external usb one. The raspberry pi runs YAAC which is a java program that has a ton of features. The pi also logs all packets and sound via arecord to a thumbdrive. It could be made into a portable unit pretty easy but I am working on putting it in my truck. Using the pi I can also run FLDIGI and sstv.

Packet hasn't really been cool since the 80s. Everybody seems to go through a couple of phases when they want to try packet (I've had at least 3 ) and then they get bored with it again. There are no PBBSs anywhere near me.

Now a lot of people are playing with sound card modes on FM (including repeaters). The local RACES nets run digital modes for half the net to practice traffic handling.

I've got a couple of KPC 3's that I use for APRS stations.  I used to do more with packet but it's fairly dead around here.

KPC3+ for vhf and a PK232 for pactor I is what I have/use.  I don't do much standard packet, mostly setup for airmail.  Our group stuff uses the pactor III modem.

If money isn't an impediment, the new SCS P4 Dragon DR-7800 modem is the state of the art. It'll do everything you'll ever want and your ham friends will drool too.

ARES and RACES are reviving packet networks all over the country. MARS is too.



I generally run peer to peer Pactor 3, but in an emergency you gotta get the message through and packet seems to have been identified as the mode most people can use to that end.

Ohhhh....that's nice.

I prefer a KPC3+ instead of a sound card interface. Much easier for me to just deal with a serial interface than trying to deal with sound cards, etc.

gcw,
I've looked at YAAC but until just recently I didn't figure out how to install Java. Not a fan of Xastir...just seems cumbersome in some of it's features. Could you tell me how you have soundmodem configured for the external USB soundcard? I've been trying to get one configured on my netbook (so I can eventually move it over to one of my RPi's) but haven't gotten the setup just right yet.

Ill get you the info as soon as I get home. What distro are you running on your pi's? For the usb sound card try this (with the card pluged in)

cat /proc/asound/cards


It will list out your sound cards. The numer on the left with 0 on top is its id. In soundmodem choose plughw,X:X where X:X is your card.

I have a crazy cold and am on my phone but that should get you started.

Running Raspbian on both of them. Headed off to Taos for the long weekend but brought my sound dongle and proper cabling for receiving on my Mint PC. I'm fairly confident that if I can get it working on my Mint PC this weekend I can get it working on the RPi's.
