<p class="MsoNormal">Hi all ...<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I figure there are two or three major
aspect of implementation of a VNA.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Firstly, whilst there has been an agreement
that it is conceivable with Hermes, I would feel that it is
important to have an implementation that used
Mercury/Pennylane. Having said that, I am very new to this
SDR project and have absolutely no idea about the viability of
same ... from a hardware or software perspective.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Has anyone given any thought to exactly
what additional hardware (if any) would be needed to implement
a VNA in the HPSDR projects as they currently stand? I guess
we have the expertise in this group to implement the hardware.
(if any)<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Which brings me to my second point. Phil
has already stated that there is some open source VNA software
(which I had already found and downloaded <span
style="font-family:Wingdings">J</span> ) which should be a
good starting point. It was going to take me some time to get
my head around the PowerSDR software in it’s own right. Add to
that the VNA software (written in Python by the way, not my
native language) and I have a steep learning curve and will
need time to get up to speed.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Are there any programmers note and or other
documentation that I can use to help me get up to speed a bit
more quickly?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">--<o:p></o:p></p>
