[hpsdr] Call for Comments and Discussion - OzyII

Wed Jul 22 01:24:14 PDT 2009

Hi Murray,

I was under the impression that they needed drivers/software in the host for
that?
That it was only the PHY hardware (I think) in the adapter?
Maybe the latest don't need this anymore I'll have to check.

More reading...... ;-)

Henry.
