Hi folks
I just got a RTL 820T cannot get it to work with HDSDR or SDRSHARP. Since I use window XP I downloaded zadig_xp_ V2.0.1 160 7Z to installed the RTL driver. It was installed successfully WinUSB (v6.1.7600.16385) then I went to options picked bulking interface 0 as suggested.
I also installed for HDSDR the EXtio RTl.dll I use a 4 ports hub with its own power. When I start HDSDR the EXtio is illuminated & select RTL EXtio.dll file I get sound but i have to push the slider WAY UP. There is also an icon saying RF +30.If i raise the slider the HDSDR software freezes. I guess the RTL does not have a soundcard because none shows up but the computer one. when soundcard icon is selected????
One more thing when I double click On the Illuminated EXtio a window called RTL SETTINGS comes up & read as follows DIRECT SAMPLING DISABLED,SAMPLE RATE 0.25Msp PLL LOCKED, TUNER AGC,RTL AGC,OFFSET TUNING NOT CLICKED
Now for SDRsharp
I select CONFIGURE & get RTLsdr/TCP which I select Then I click play a window comes up & reads as follow:
" no connections could be made because the target actively refused it 127.0.0.1 1234 " Now I assume that 1234 are the ports of the hub I am using.???
Also if I click on CONFIGURE a window comes up & says : RTL-TCP Settings
Host : 127.0.0/1
PORTS 1234
sample rate 2.048 MSPS
RTL AGC NOT indicated
RF gain OFF
Now I wonder if i should select ONLY the port where the RTL is plugged in??? or does it matter since it is a HUB???
BTW I use also a Funcube dongle Pro with HDSDR & SDRSHARP with no problems.
Your help will be very much appreciated thank you!!!!

Re: Computer Requirements to run SDR#

Speaking of C++ vs C#, I admit one needs to be more than "simple developer level" at C++ to write good performing C# code. Now to write faster code in C# that is also better looking is somewhat of an art. Many people seem to believe that simply using C++ or an optimised math library such as IPP, BLAS and LAPACK will cure all their performance problems. It is really no surprise C++ can outperform .NET. Unfortunately, nobody seems to be able to write efficiently in C++ either.

Time for a simple demonstration of how poorly performing .NET vs C++ really is.

The videos linked below show a single core Atom N270 at a 1.6GHz clock. Both applications are performing a mono WFM demod from the same IQ recording at 2 MSPS rate.

We regularly use this CPU as our baseline benchmark because it is such an awful cpu without OOO execution. It does however support up to SSSE4 (not used in SDR#!).

Note which application produces the most coherent audio. Note which application has the lowest latency. Note which one is not written in C++ or using IPP.

PS. When I'm waving my fingers while playing with SDR Console V2, I've clicked to tune to another frequency. I'm waiting for something to happen due to the insane latency involved

Simon, maybe it's time you finally enjoy the cleverness of C#? We can help.

Yes, correct. That's why I have ever avoided using GDI+, sticking to bare GDI.

GDI+ has more functions, granted, but if you, like me, do not like filled spectrums,
or other embellishments that add nothing in terms of information contents, then
you do not have much reasons to use GDI+. What GDI offers is enough for the
spectrum/waterfall of an SDR.

One very easy way to chew up the CPU is being over-enthusiastic with the
graphics. Most SDR programs use GDI+ which itself does not support hardware
acceleration.

For lower-powered computers I set the SmoothingMode
http://msdn.microsoft.com/en-us/library/windows/desktop/ms535815(v=vs.85).as
px to either high quality or high speed, this can make a very big
difference. Adjusting the settings of Graphics
http://msdn.microsoft.com/en-us/library/windows/desktop/ms534453(v=vs.85).as
px is worth investigating, if anyone who programs SDR# is interested I can
pass on my log/high power CPU suggestions for this.

Re: [SDRSharp] FUNcube Dongle Pro+ / SDR# v1.1.0.0.1161 / WXtoIMG version 2.10.11 - volume change

Roberto Rizzardi <robertorizzardi@...>
 

If you have Win XP as the operating system, as I presume, in the audio section of SDR # select in the Output MME Microsoft Sound Mapper or your sound card and the Gain to 50-60%, while in the Recording task of the audio control of your pc you must select Stereo Mix.
Open WXtoImg and, after selecting your sound card in Recording Options, click on the Manual Test in the Record task.
Moving the cursor in Stereo Mix you will see increase or decrease the volume in WXtoImg and up to 50-55% is sufficient.
Now you can close the test and try to get a pass with these settings.

Usually all the fancy features of game oriented modern GPUs are not used
in an SDR program.
I don't know what happens under the curtains when you use .NET, but if
you practice a safe
life and do not use it, what is usually done is to build what should be
displayed in a memory
bit map, and when ready it is bit-blitted at once on the display card
refresh buffer.

So, as long as the GPU is capable of a decent bit-blitting speed, it is
more than adequate for
displaying spectrum/waterfall of an SDR program.

Or, if you have a GPU supported by the new libraries OpenCL of AMD, you
could demand part of the
DSP processing to the highly parallel processors of the GPU. But, as far
as I know, currently no
released SDR program does that.


Re: [SDRSharp] FUNcube Dongle Pro+ / SDR# v1.1.0.0.1161 / WXtoIMG version 2.10.11 - volume change

Siegfried Jackstien
 

You just have to set sdrsharp to send the audio to your onboard soundcard
(so you hear the tones) ... then set recording options in windows to use
"stereomix" as the input ....

Now wx2img does use the sound from speakers (what is sent to them from
sdrsharp) .... same as you were using line in or mic in with an external
receiver ...

Then you have 2 options to control the "volume" in wx2img

The audio out in sdrsharp (to speakers)

And the stereomix slider in the recording mixer (from speakers to wx2img)

(and depending on what os/mixer/hardware you use maybe wave out AND masters
out do BOTH control the volume TO the speakers)
