Dear Fellow Flexers,
Please allow me to share a little trick that I've stumbled upon, using PowerSDR
v2.0.16 with my Flex 5K, that seems to dramatically improve band noise and
woodpecker noise filtering while improving the effectiveness of Noise Blanker 1
and Noise Blanker 2.

Hi Steve,
I have made a few of my own with Photoshop that I use, but haven't come
up with anything special. It would be nice if there was a repository
where we could upload skin folders that could be shared, downloaded, and
unzipped into the PowerSDR/Skins folder. I'm sure there are some very

be something new.

What does the scale of negative numbers on the left side of my PowerSDR

Blacksburg, VA, on 60M Channel 2 the scale reading of the noise floor is
about -115. I am using the Panadapter, with AVG selected on my

I think -70dbm is s9 by most people's definition so you can go downwards
from there. Just look at the S Meter on the upper right and you can get a
quick appraisal of dbm to S units!

Carter ( Brian),
It takes a measureable amount of processing resources to draw update in
real-time the waveform on the Panadapter display. As I understand it, the
design decision was to not draw the output waveform for CW in order to be
able to apply the resources saved towards better

I shall try to follow your suggestion.
Now if only I knew what FFT bin in dBm means. I know what the dBm part
means...
The spectrum display looks like a continuous line but it is really a

Neal,
Actually, S9 is defined as 50 uV into 50 Ohms. O dBm is defined as 1 mW
into 50 Ohms. That calculates to S9 = -73 dBm.

The width of a panadaptor FFT bin in Hertz is your sampling rate divided by
4096.
In other words, your panadaptor display is a vertical bar graph display of
received
level for 4096 very narrow band receivers setting side by side by side ... .
So if you set your receiver bandwidth to the same bin
Here is the simplified version of the skins license as I understand it.
If you use an existing, copyrighted skin as the starting point for creating a
new skin (modifying the graphics files), even if it is just one image file,
then you may do so as long as the skin is utilized for your own
IIRC...
S9 is defined somewhere by someone as 50uV into 50 ohms (i.e the
antenna input to your rig). If you do the math to convert this to power
and express it as dBm, I believe it comes out to -73dBm.
An S-unit is equivalent to 6dBm

Fascinating reading, and thanks for that link. Mostly way over my balding
head, but I think I got a better grip on it than before.
Thanks Teach... (My former students used to call me that too, Hi!) Those

Ray's explanation is dead on. It reduces the system latency in CW mode which
is critical for it proper operation.

That was good reading. I hadn't seen that link before. I love the 3D spectrum
over time display. I've got a guy here at work, that has written code to
control our HP/Agilent spectrum analyzers so we can monitor the RF spectrum in
3D over time. Would be really nice to see that on a Flex 5K

I need help getting v2.0.16 installed and running with the Flex-1500. I
previously had v2.0.5 running fine on CW (never could get v2.0.8 to run CW
without gliches). Recently decided to try to get PSK/RTTY modes setup with the

You are right. Max HP occurs about 5%-10% rich of best stoichiometric
