It can be connected to computers, Android phones and other devices to use SDR software to receive 100KHz-1.7GHz electromagnetic waves and support AM, FM (NFM, WFM), CW, DSB, LSB, and USB demodulation. Can listen to short-wave single-sideband communication, FM radio, walkie-talkie calls, aviation bands, etc. The analog sub-tone and digital sub-tone can be cracked through the software. Automatic search scans can be set up. The ID of common digital walkie-talkies can be cracked and the voice signal can be demodulated by software. This machine, 24hmz can not receive the signal, the aviation band effect is good, if you need to use 24hmz, please choose other bands. Use RTL2832U + R820T2 chipset 100KHz to 1766MHz operating frequency Cover all short wave amateur bands Cover VHF & UHF bands from 24-1766MHz. Up to 3.2M sampling rate.
