Thanks for the suggestions. It appears there is a more fundamental
problem here in that soundmodem seems to stop receiving after some
time. I'm not exactly sure how long - I'll have to set my VX-8
beaconing at two minute intervals and see when it stops receiving the
position reports - but I have noticed after some time that it does not
receive anything the HT sends until I restart the computer. I can't be
sure that this is not the cause of the problem I reported, since
xastir may not be hearing the VX-8 even though it has been sending
beacons.

I had to apply a hack I found through Google to the soundmodem code to
fix a problem that it tries to open the soundcard at a 9600 sample
rate and the soundcard in the Eee PC doesn't support it. I don't know
if that is the cause of the problem because it didn't work at all
without the hack. But I did notice that the diagnostic oscilloscope
screen in soundmodemconfig freezes after a few seconds, which didn't
happen with the version that came from the Ubuntu repository. Is there
a list where I can get help with soundmodem?
