How to properly record Raw IQ data via Web UI?

1

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!
