If you get a black screen (or any useless screen), press "S" to get back
to text mode to try another alternative. If this does not work you have
probably detected a bug in the 2.6.10-r4 core. Did you select "N" for
"use memlockall" ?

This is a problem in linrad that I no longer remember the details of. I
have made some changes to accomodate for the new OSS application program
interface recently and there may still be some errors. Try linrad-01.28
(or earlier) which should not have this problem. With this version (and
earlier) be careful to set the true hardware sampling speed, you can set
any speed but that forces oss to make a rate conversion that may be
problematic for linrad.  Once you have 01-28 running, you can copy  the
par_userint file to your linrad-01-31a installation.

Do you have two output channels on this computer?
The coherent modes require stereo head-phones.
 (Except for coh3, but I have not allowed it because one has to
understand how it works to use it properly and the other modes should be
helpful for that. coh2 is better to use on really difficult signals
while coh3 improves S/N for a signal that is good enough to never loose
tha carrier. )

I have never tried this one so I do not know if there is something
particular with this distribution/kernel.
