<p class=MsoNormal><font size=2 color=black face=Arial><span style='font-size:
10.0pt;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.<u1:p></u1:p></span></font><o:p></o:p></p>

<p class=MsoNormal><font size=2 color=black face=Arial><span style='font-size:

the available hardware (ADC, DAC, data transfer and processing power)
capabilities are all catching up with the dreams!<u1:p></u1:p></span></font><o:p></o:p></p>
