How to properly record Raw IQ data via Web U?

Hi everyone,

I am working on a Machine Learning project and I need to record Raw IQ data (complex64) from my KrakenSDR. I am using the latest software version on a Raspberry Pi 5.

I have followed the DeepWiki instructions:

  1. Enabled “Beta Features” in System Control.

  2. Set “VFO-0 IQ Channel” to True.

  3. Reconfigured and restarted the DAQ chain.

However, in the “Local Data Recording” section, the “Data Format” dropdown only shows “Kraken App”.

My questions are:

  • Is the .iq file being recorded automatically in the background even if the dropdown doesn’t show “Raw IQ”?

  • Is there a way to confirm the raw recording is active from the Web UI?

  • Are there any CLI alternatives (command line) to record raw data directly to an external SSD to avoid Web UI overhead?

Thanks in advance for your help!

Would like to know as well!!!
