The KrakenSDR will automatically have started processing. Ensure that the Connection Status, Sample Delay Sync and IQ Sync indicators are all green, or all turn green after a few seconds if you opened the page during calibration, and that the Frame Index is increasing. 3. Set the desired center frequency, gain, antenna array radius configuration, and other settings like VFO bandwidth and squelch for the specific signal of interest. Make sure to apply the update by clicking on “Update Receiver Parameters” after changing the centre frequency or gain settings. 4. Check the Spectrum screen to ensure that your signal is being received as expected. |
