Turn your mobile phone into an All mode communications receiver from 0.1 to 2000 MHz !
This video shows “SDRplay” Software Defined Radio running with my Android mobile phone, receiving USB on 20m Band (14 MHz).
The software “SDR Touch” and SDRplay driver are downloaded from Google Play Store.
Some mobile phone USB ports simply do not have enough power for the SDRplay receiver (my phone usb port, did not provide enough power also), therefore, I sliced the USB OTG cable and added (soldered) additional connector for an external 5 volts power source, or 5V battery pack. In that way, the external battery is charging the mobile phone and powering the SDRplay-receiver at the same time.
