Hi Kees, You could try playing about with the sampling rate keeping it low values which will have a direct response on the spectrum display. Try clicking the "L" which is the low sample rate? Also

Hi Brian, Thank you so much. That was the solution. I have a lot to learn :-) 73 Kees PA3KVE

I know see that the Baseband sample rate is 150 kHz (see 150k on screenshot). Can I get that higher ?

Hi Kees, Why not just change the Decimation factor from the value of 16 down to something much lower, even 1 which will allow the full available coverage of the RTL-SDR dongle? Regards, Brian EI8EJB

Hi David, Thanks for coming back. I am a bit confused by your answer, as I think it is a SDRangel question :-) In SDR# I can see the spectrum for 2.4 MHz width, so no questions there; in SDRangel I

Hello, Using SDRangel (which is great by the way!) makes me wonder why I "just" can see about 200 kHz. In SDR# and other sdr-programs I can see 2.4 MHz with my RTL-SDR. SR = 2,400,000 S/s Any help

Hello, I haven't had time to try to reproduce using the details given by Steve below. However this seems to confirm that this is related on how the audio system and the chain all the way up to the

The kernel I use is 5.3.0-26-lowlatency #28-Ubuntu SMP PREEMPT (Ubuntu 19.10) I did a transmission test this evening with the Pluto sdr using NFM and a (usb) microphone. I didn't hear any or see any

I reformatted the SBC and installed Ubuntu 19.10. The audio artefacts were different; better. The attached image 'ubuntu1910.jpg' shows the Channel Spectrum during a Fldigi PSK31 idle 'transmission'

Hello Edouards. Many thanks for this confirmation. After many trials I use this solution , and also with squelch feature.: File is registered only when incoming audio is above 0. sdrangel is streaming

Further tests: sdrangel.log shows all devices & DLL had been loaded Override high DPI in the sdrangel.exe setting activated still no more devices in the 'sampling devices' list... 73's de

Hi all, running 4.12.5 in Windows 7 pro (YES, I know, 14 Jan 2020...) and in the sampling devices I can see only: File input KiwiSDR LocalInput RemoteInput TestSource Tried to reduce my screen

I installed a pre-built low latency kernel, and that appeared to help reduce dropped packets a tiny bit with my Limes, maybe a 10%-ish improvement. So I built and installed a full real-time kernel,

Thanks Bob, that's useful information. I have carried out all my testing with the sample rate set at 1-2MS/s. Kind regards, Steve

Dear Edouard, Many thanks for the detailed reply. Here are some answers: - The issue is only with TX. - No issues with CW generated with the Morse keyer mode. The 'Tone

Hello Remi, yes you can send the audio mix via UDP as explained in the Wiki. There is no example of storing the audio file at the other end of the UDP pipe but apparently you managed this part. This

Hello, let me try to recap things... Issue is with transmission right? So I have a first bunch of questions: Do you encounter the same issues with a CW transmission (either pure CW or in Morse

You can also limit the sample rate. Here I start to get small audio interruptions when set too high on reception, let say above 4 MS/s. This without touching the priority. Bob VE3TOK -- When you
