I'm about to give up on ever getting getting packet/aprs working under linux.   I've tried FC10 and 11, and ubuntu 9 (and possibly 8 too).   I've tried using a dell D600 and D400 laptops as well as virtual machines running under VMWare Fusion (Mac).  

I believe my problem is with soundmodem.  I've tried source as well as packages (all the ax25 stuff loads fine with no indications of problems).   I can run soundmodemconfig  and create a configuration/channel (typically I use /dev/dsp, /dev/soundmodem0, and KISS).    I can start the diags and watch my radio input on the o-scope, the levels look fine (maybe 75% total deflection? no clipping) and I see the APRS data.  Not only that, I DO see the DCD light up when I see the data.

What I *never* see however, is any decoded data in the modem window after testing for hours.   Despite that failure, I'd soldier on and try running xastir.  And again after hours of running, it would see no data on the interface.

Before I give up and just buy a TNC, I just want to hear is that someone can confirm they actually can run soundmodem/APRS on FC10, FC11, or Ubuntu.   Besides that I would greatly appreciate any tips and suggestions.

Direct replies are fine too gary.huntress@gmail.com

Cheers,

Gary H.

I haven't used it in a while, but a while back I was running Ubuntu 8.04 on a Dell D810 laptop.  I wanted to try out some Ham radio applications where I could copy some PSK31.
What I did was load "wine" on my Ubuntu system.  You may know that wine allows you to emulate a windows environment in Linux.
I then loaded up Digipan and it worked great with wine.  I also ran a demo version of Ham Radio Deluxe on my Ubuntu system using wine.

I run many other windows programs on my Linux system, using wine, and so far very few did not work.

You might give it a try.

I have used soundmodem with Xastir.  I run a Debian system here which is somewhat close to ubuntu.  I can't say anything about Fedora because I moved away from Red Hat many moons ago.

I had it hooked up to my HT and was talking with a few guys here locally.  I did run it through a homebrew sound card interface.

Hope this gives you some motivation.

Perserverence, thats what it takes!
I still don't think my audio levels are perfect, I'm not decoding nearly the amount of traffic I think I should be but it does work Smiley

Thx all!
