SDRuno Issue today

[KM4FLF]

I am running the SDR play with the TS590SG. I am running it through the DRV connector. SDRuno has been working fine since the latest software update.
Today when I turned things on, I have an intermittent receiver drop. every couple of seconds the audio stops and immediately starts back. It does it in all modes and all bands. I tried switching AGC modes, as well as adjusting squelch, but it continues. My animation ....shhhhh---shhhhhhh-shhhhhh=shhhhh.

I reloaded version 1.03 but it didn't correct the problem. I opened the SDR play using HDSDR. I have no problem with this software and everything is working fine.

Any ideas of what gives with SDRuno??

One thing you can do is check and see in both SDRUno and HDSDR what the CPU load is for the program, and for the system overall. I also have had SDRUno stutter on a not-very-powerful computer whereas HDSDR because it uses less resources does just fine.

Thanks for the reply. Definitely onto something on CPU issues.

I have a Dell Inspiron with a 2GHz processor and 4 GB Ram. I checked CPU and Memory use and there is definitely a major difference between SDRuno and HDSDR.

SDRuno:
50 to 52 % CPU use (On system tray shows 48-52%).
47% physical memory.

HDSDR:
14 to 22% CPU use.
46 % physical memory.

I turned off all background programs except Norton, and it does not make a significant difference in CPU usage. I will say that the skipping is not as bad today when I turned everything on. I have been using SDRuno for about 3 weeks until this issue suddenly appeared.

Is there any setting is the SDRuno software that would minimize CPU usage?

If you let me know what your settings are (you can send a screenshot to support@sdrplay.com) I can let you know if it's optimum from a CPU point of view. Also, make sure the PERF button is OFF

Best regards,

I sent the screen shot to support. I discovered today that Band With seems to be the CPU resource user. I have dropped BW to 7 Mhz and my CPU is running 39% and not stuttering. I will try keeping bandwith 7 or lower and seems to have fixed my issue.
