Those of you who have a desktop computer with an available PCI slot and
are looking for an alternative soundcard at a lesser price, you might
want to find a SoundBlaster Live 24 as an add-on. It is a 24 bit
soundcard that can operate duplex and has a decent dynamic range and
good S/N ratio.
I have mine configured as the default soundcard because I like to listen
to good music and do recordings. I will also use it for the receiving
end of my Z10000/Softrock panadapter when that project is finsihed.
I then use the stock on-board computer soundcard (not the default card)
for digital modes since I can see little difference in the *usable*
dynamic range - (my computer uses a SoundMAX) - it is not the greatest,
but it does OK for me in digital modes.
The net result is that Windows sounds can occur 'on-top' of my music or
panadapter output, but I will not be transmitting those sounds because I
do not use this default card for data modes.
If you are using a laptop for the shack computer, then you best choice
is an external USB soundcard. I prefer to use a desktop computer in the
hamshack.
