<DIV>Hi Bruce,</DIV>
<DIV> </DIV>
<DIV>Thanks for your feedback. It was not my intention to limit the
suggestions to receiving only, for sure we can apply the same philosophy
to the transmitter. For the time being we may be pushing our luck to do
wideband on Rx and Tx but multiple transmitters, along the same lines as we do
presently, would not be a problem.</DIV>

style="FONT-SIZE: 10pt; 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>

style="FONT-SIZE: 10pt; 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>
