WebSDR with airspy mini. Technical specs: 24 MHz bis 1700 MHz.

Usually, it's loud at our location (what's nice anyway): no Audio, but "only" graphical view of amateur radio signals, or decoding of digital transmissions. Btw, the 70cm ISM-band is in behalf of the amateur radio band. If you like to verify the transmitter of your project, our SDR could be a good choice.
