<p>Thanks.</p>
<p>My "sniffing" comment is based on what I remember reading.</p>
<p>What I want to do is intercept frequency information going form
HPSDR to wherever to glean the frequency the radio is on, and
switch antennas and/or filters. (Right now filters) I've read
that there is some UDP "signal" to multiple addresses that people
intercept. If I can just grab UDP packets with a RaspberryPI,
that would be cool. Then the PI could command the relays. I
could also grab CAT2 or CAT3, at least on the portable SDR; that
computer has a real serial port. I'm not sure (at the moment) how
many serial ports the computer used to virtualize the fixed SDR
has; will look.</p>
<p>Thanks, you have been MOST helpful over the years. And I LOVE
the product!</p>
<p>Thanks & 73,</p>
<p>Jim</p>
