Hello Rein and All,

> Assuming that the linrad file is a stand alone file ( Program )
There is also errors.lir and help.lir that I forgot to add into
the zip file. The program runs without them but you will not get
error messages.

It is a statement. I would be very happy if someone could 
tell me how I can query a soundcard to get its capabilities.
The only info I can get is the vendor text string.

You would typically select 3 and just not feed anything into
the second channel unless you have direct conversion hardware.
(Better use a mono-capable soundcard)

This means that sound output could not be opened.
My guess is that Windows does not support full duplex for SB16

Remove par_userint to get access to "U". Then type "W" after you
made your choices AND EXIT IMMEDIATELY. (a bug, both under Linux
and Windows) Then restart linrad.

To get weak signal CW, remove par_wcw* and restart. 
The modes "A" and "B" is exactly the same code. Only
the parameters differ so you can set the parameters
to a working initial state by copying all the
par_cw* files to par_wcw

This does not look right. Parameters not saved correctly - but it
could be because of the bug.........

Yes. Try fresh without par_userint and save immediately.
Then exit immediately (This is ONLY for Linrad-02.00)

Presumably Windows does not think the cards are properly 
installed;-)
