[Elecraft] USB Sound Card

[Don Wilhelm]

Tom,
Tom,

If you want to use the soundcard for panadapter applications, then go 
with the recommendations on the LP-Pan site, but there are several users 
that have been reporting that the ASUS U7 reverts to 48k and there does 
not seem to be a solution.  The ASUS U5 does not seem to share that 
problem.  In addition to the bandwidth of the card, the noise floor and 
the lack of a zero frequency spur are important considerations.
Look at the LP-Pan Yahoo Group for a lot of comments.

If your soundcard will be used for digital modes only, then you do not 
need a 'top of the line' soundcard, most any will do.
But the LP-Pan website can still be an assist in selecting one - look at 
the noise level on the various cards to find the better ones for 
soundcard digital mode use.  The internal soundcard in your computer may 
prove to be adequate, but turn off the sounds generated by your OS if 
you use the internal card so you do not transmit those sounds.
