Alejandro, The Spyverter will shift the 457kHz signal up by 120 MHz, so the result will be 120.457 MHz. Connect your 457kHz signal to the input of the Spyverter; connect the output of the Spyverter to the rf input of the hackrf. Remember to apply 5Vdc to the Spyverter (make sure you use a linear power supply, or a battery pack, because a switch mode supply will be very noisy). You can use gnuradio companion (or numerous other programs) to show the spectrum.

I'm writing this e-mail because I'm using HackRF-One SDR as a spectrum analyzer in a university project. I'm also using a Spyverter converter (https://airspy.com/spyverter-r2/) and I'm having troubles to configure correctly the device, since I'm not very familiar with it. I'm interested in detecting with the HackRF-One a signal which is at 457 KHz (out off the range of operation), therefore I need the Spyverter to achieve it, but I'm not able to configure it. If you have some experience with this device used with a HackRF, or there's any website I can get some information about how to configurate it, I'll apreciate it a lot. Thank you very much in advance, Kindest regards, Alejandro Ramiro. -- Alejandro Ramiro Muñoz NIA: 100314975 Grado en Ingeniería de Sistemas de Comunicaciones (Bachelor's Degree in Communication System Engineering) Universidad Carlos III de Madrid
