Thank you for the advice. However, even after commenting out all RX-related functionality, I still see occasional TX data drops at a 12 MHz sampling rate.

I am currently running limeTRX on a Windows 11 system. In the following post, [oe1rsa](https://discourse.myriadrf.org/u/oe1rsa) reported stable TX at 40 Msps when running as root:

As a “work around” I manually force the extra config to strcfg.extraConfig.rx.packetsInBatch = 8; This results in smooth operation with very low CPU utilisation and no data losses. (Tested with 4Msps over a period of 10 minutes, while doing email and internet surfing and no escalated privileges, i.e. as a normal user.) I also tried wi…

This makes me suspect that the issue may be related to the Windows environment. I will try running limeTRX on Ubuntu, using **nice** to increase its scheduling priority, and see if that improves the stability.
