<div class="moz-cite-prefix">Hi,<br>
<br>
Just a little report here.<br>
Running hermes-board and 2.3 firmware and I7 PC W7-64.<br>
Everything seems to work o.k. also on the max panadapter
bandwidth of 1.1MHz,<br>
and even nicer (AM) audio now then before. <br>
<br>
Audio buffer size: 2048, sample rate: 384000<br>
Display FPS:60 Bin Width:2.930 DSP buffer Size:8192<br>
Maximal CPU : +/- 23% and the 100MB network use : +/-90%.<br>
<br>
Things I discovert are that at DSP buffer Size 16384 (max) and
in combination with ANF or NR enabled that the panadater gets
problems to stay "real time".<br>
And that at the XVTR setup, when adjusting the RX-gain (to
calibrate out the transverter gain), the panadapter is not
adjusted. the signal meter is adjusted o.k..<br>
The NB has some problems in the AM mode.<br>
<br>
Thanks for this really nice upgrade, the higher resolution
panadapter is great for us "weak-signal hunters" now I'm ready
for that "WOW! signal"<br>
Thanks to all that are involved, Warren, Doug ... <br>

<p class="MsoNormal">Does your CPU need more exercise? Want
to see more on your Panadapter?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Doug and I have collaborated on a new
release adding some new features:<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">**Deep FFTs (FFT bin-widths as small as
0.184Hz) – Mercury, Hermes, and Angelia.<o:p></o:p></p>
<p class="MsoNormal">**Wide Spectrum Display (displayable
spectrum of over 1 Mhz). This width is for Hermes, RX1 only
at the moment, and at the new 384K sample-rate. However,
Angelia supports a wider display also … and stay tuned for
more announcements!<o:p></o:p></p>
<p class="MsoNormal">**Fast Update Rates (up to 60 frames per
second at any selectable FFT-size and displayable spectrum
width—assuming your CPU is up to the challenge!)<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Why might you care?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">**Deep FFTs means smaller frequency
“bins” which means less noise per bin; this lowers the noise
floor and makes weak signals more visible. The smaller bins
also mean better frequency resolution on viewed signals and
better resolution for frequency calibration. Those large
FFTs make great spur hunters too.<o:p></o:p></p>
<p class="MsoNormal">**Wide Spectrum Display—You can see more
of what’s going on around you in the frequency spectrum.<o:p></o:p></p>
<p class="MsoNormal">**Fast Update Rates make the display more
interactive and pleasant to view. They also allow you to
better see transient signals that might be missed between
less frequent updates.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">But, take care! We’re sure some
government or its agency has determined that such bold FFT
computing could be hazardous to your CPU’s health and might
induce CPU heat stroke.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">As an added bonus, there’s a new
NoiseBlanker –be sure to reset your NoiseBlanker parameters
if you have a job for it.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">We hope you enjoy the new release. More
details on usage are found in this document: <a
