DPC Thumping

in SmartSDR for Windows

My Transmitter spectrum has noise pulses. I saw this sporadically with my 6600 and see this similarly with my 8600. In previous years it was explained as DPCs (Deferred Procedure Calls) and manifest as noise artifacts on the transmitted RF waterfall. See screenshot:

I previously had WIN10 i5 and i7 HO refurb desktops. I upgraded to a new WIN11 thinking this would allow me 3 monitors and 1 mouse with plenty of reserve to handle multiple windows with various tools (PSK Reporter, Slack, DXMaps, etc). Now I guess I would be better having those web tools on my old computer and the Flex apps on the new WIN11. Is there any plan to change the SSDR code so that when the Flex transmits, it blocks the web app DPCs? I now see this is becoming prevalent from other Flex radios while monitoring various FT8 frequencies.

    You can try something like Process Lasso Pro that allows control of priority etc for apps.

An inline formatting menu will show up when you select text. Hit tab to get into that menu. Some elements, such as rich link embeds, images, loading indicators, and error messages may get inserted into the editor. You may navigate to these using the arrow keys inside of the editor and delete them with the delete or backspace key.
