Hello Andy,
There was a very good article in QST a few years ago about sound cards.
They ran five different cards through quite a battery of tests in the ARRL
Lab and yes indeed, you really do get better performance out of some cards.
But dollar for dollar, the performance was not linear.
Where is everybody hanging out?

Hello Doug,
It sounds like you have quite a bit of RF in the shack. I have D-Star
here with no problems on an Icom 91AD. Do you do a lot of transmitting into
non-resonant antennae? Do your radios still lock up when transmitting into
an antenna that is closer to being resonant?
Yes, thank you very much.
Rick KH2DF/W5

My Icom 746 suffers the same problem. I had hoped that the Elecraft K3
that I had in mind would solve this issue for me as well but maybe not. The
review in QST was the best they ever gave but maybe I hope for too much.

Hello,
The ARRL also sells a very nice book about Digital Signal Processing
although at $45 it is a little expensive. I am just getting started reading
it but if you want to know how all of this stuff we are doing in digital HF
really works, this would be the book to read.
Rick -
is... if you have the pack already on your HD, how do
you take care of the install when prompted to insert the CD with the
service pack on it ?
Andy.

If you turn Automatic Updates on, it should load in less than a day or so of
leaving your computer on. Or you could go to Microsoft Update and let it
install from there. After that, I would go to the sound card web site and
download the latest driver . . . should work.
