Hold on there bobalouie. I'm hope Linux overtakes. I'm glad to hear it
works AND someone is actually doing it. The thing is, I have Flex
working in DOS/WIN but can't find a APRS program fer it. What better
than to hear someone actually using it. The combo I am asking about is
Linux AND Soundcard AND APRS. If we can an easy to use home install
with Linux, it will fly. I like is robustness yet it needs to work for
mom too. :)

That's cool.
I guess what I'm asking for are the adantages of running soundcard/APRS
and such on Linux compared to Windose.

This can be the case when it does not use Kernel AX.25 but talks to a TNC
connected to a COM (tty) port. Some programs do that.
You can circumvent that when you have a suitable emulator for the TNC type
they expect, and interface that via a pty.

Subject: SOUNDCARD SAVES PACKET HAM RADIO?
Programs like AGW Packet engine 2000.72 now allow your Pentuim +
soundcards to take the place of TWO 9600/1200 TNC's! Combined with a
easy to tap into "true FM" rig you can do 9600. 1200 baud requires no
modification.
Can you say new and free (with what you may have) 9600 baud network?
Could this revive Packet?
9600 is fast enough for TCP/IP and is wireless. One can use your
regular Internet programs. FTP, HTTP, Newsgroups, Telnet ect.
Can you think of some real benefits from this?
Sure, work on faster but don't forget the cost!
Further if you don't think this is in the "spirit" of ham radio or
something then simply go and do what you will. Just don't dictate what
I do. TO EACH HIS OWN!
Stop the bickering. You'll make us all look bad. If you want to do only
CW then I GOT NO PROBLEM WITH THAT! Just mind your own business and
don't rain on my parade. I think it's wise to combine various
mode/bands whatever for a communication benefit. If we don't focus on
some benefits ham radio will soon be sold off.
So I hope you get my point. Don't turn this news into a bar brawl. I
hope I'm clear. If you don't want to do anything but RF or CW or
Internet or whatever then fine. I HAVE NO PROBLEM WITH THAT! That's OK.
I am simply on a quest for benefits. Benefits for emergency, benefits
for everyday. Ask yourself; when the fun (of tinkering) is over, what's
left?
Plus! While this is a technical hobby, let's not fail to distill THE
TECH down (EASY OF USE) so new hams and the not so technical can
benefit form it AND GET STARTED. After all guys, intelligence isn't
that big a deal compared to communication and caring. Let's stop trying
to prove how smart we are and get down to business.
Sorry for the rant. I've just seen too many "bar brawls" when someone
tries to promote a real benefit in Ham Radio. What can you say about
the soundcard "revival"?

God bless
Be well

Even with a true FM rig, you probably aren't going to be very happy
with your results. Think about getting a TEKK data radio. They are
cheap, and they work well.

Yes, for portable applications(PDAs, laptops).

Using a soundcard also isn't going to make you happier... you need audio
coverage down to a few Hz or preferably to DC. Soundcards are designed
for audio and smallish speakers. You may be able to increase the values
of coupling capacitors, but with some bad luck there is filtering that you
cannot work around.
I have once converted a commercial FM transceiver that had really true FM
in that a small variable DC voltage on the line input would actually sweep
