Re: V3 build 940 crash when more than 8 receivers were open and questions about audio recording

Simon Brown
 

Victor,

 

Excellent report, thanks. Will look at reducing this further now, have managed to get a crash on another system so must also find that as well.

Simon,

Most of the time, I only concentrate on the frequency spectrum display window to look for frequencies with signal. If the waterfall display can be switched off / disabled, does it affect the demodulation / processing of the signal or reduce the memory usage (in that case, a button will be needed to toggle ON/OFF the waterfall display)?

Hi,

 

I just sent you a link to a 32-bit kit which uses a lot less memory on my 32-bit Windows 7 system. Feedback requested 😊 .

At the mean time, I can temporarily reduce the memory usage by setting the "bandwidth" to a lower value e.g. to 2 MHz / 1 MHz etc.

Re: Center signal. With no antenna sig it's there and with antenna it's modulated

Alan G4ZFQ
 

in the center a signal that
also is present with the antenna disconnected (pic 1) ,
Kees,

This is normal with soundcard SDRs. Avoid using the centre.

and is modulated when antenna is connected (pic 2).
The best bee seen (and also mist annoying) on the higher bands.
Maybe due to very strong local AM station?
More noticeable on high bands because noise is lower there.
If so a High Pass Filter would help.

Re: Oct 23 Preview Does Not Record To C: And No Error Message

David J Taylor
 

I can't record to C root. If I select a folder, everything's ok. If I select the root of an external drive, everything's ok.

If not to record to C root is intentional, maybe there should be an error message.

(And to be honest, I don't record to C root, it was just a quick & dirty test to see how the new preview performed).

Bjarne,

Under later versions of Windows, direct write access to C: may involve going through one or two security hoops, so the problem may not be in SDR Console.

Cheers,

Re: audio stutter with Airspy decimation

Hi,

 

Great screenshots, many thanks.

 

Please look at http://www.sdr-radio.com/Radios/Airspy/AirspyServer which I wrote yesterday. Your CPU load is not too high, I see you have 5 (maybe more) receivers – you could try just using 1 or 2 and see how that works?

 

Looking at the logfile you do have stutter, *maybe* due to running all receivers through the same soundcard, if this is not the case then increasing the Buffering may help.

Hi,

 

  1. I updated http://www.sdr-radio.com/Support/Computer look at 32-Bit vs 64-Bit
  2. I suggest 64-Bit Windows on your existing computer if possible
  3. Yesterday evening I spent time reducing the memory foot print with considerable success, I will give you a direct link to a kit later today with luck, I need to do more testing

Mark,

Concerning the CPU usage, reducing the waterfall speed (VIEW/SPEED) can significantly reduce the CPU usage.

It seems that 4G is the RAM size limit for 32-bit Windows.
In my case, adding RAM is impossible unless updating to 64 bit Windows or simply buy a new up-to-date computer system.

The only thing I can do is reducing the RAM usage of SDR Console. In my case, the value is about 1.5G. What kind of setting can be changed to reduce the programme RAM usage?
