Probably a noob question but I’m curious to understand why the frequency limitations for the kraken are 100-1 while the actual limitations of the RTL SDR are from the low HF range to 6 GHz. Is this a software limitation or simply due to the massive nature of a VHF antenna array for direction finding 35-45 MHz?
@gojiba The frequency range of any normal RTL-SDR is ~24 - 1766 MHz. Some specific models (such as the RTL-SDR Blog V3) bypass the tuner so you can tune into frequencies below 24 MHz. I’m not aware of any RTL-SDR that goes above ~1800 MHz without an external down converter. Would you mind linking to one of the radios you are referring to? Are you maybe thinking about the PlutoSDR or HackRF?
I could be thinking of the HackRF, I use them both for work (I’m an EW guy). In any case, I would be super interested if future firmware iterations allow the kraken to direction find between 30-88 MHz. If that’s already possible with the correct array I suppose I’ll try it out.
