font-family:Arial'>Nice write-up Phil. Thanks for sharing your thoughts on a
future path of SDR development. In your text, I read SDR as primarily "software
defined receiver". I would like to see a broader "software defined
radio", to include expansion capabilities in the front end hardware,
including TX. In my mind, this should include not only the ability to add
multiple ADCs for receive, but also multiple DACs for transmit. This would open
the possibility (for example) for both transmit and receive "beam
steering" using software determined phasing of a vertical antenna array
for both transmit and receive. Other applications would also be possible with
multiple independent transmit and receive hardware paths.<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>It's a fun time to be discussing all this, now that the
available hardware (ADC, DAC, data transfer and processing power) capabilities are
all catching up with the dreams!<o:p></o:p></span></font></p>
